According to the Biocodex Microbiota Observatory, only 32% of French people know precisely what the microbiome is. Yet it influences your child's immunity, digestion, and even mood every single day.

You hear more and more about the microbiome these days. But what does it actually mean for your child? And why does it matter more during childhood than at any other time in life?

Your child's gut microbiome influences their immunity, their digestion, their sleep, their mood, and even their ability to concentrate at school. And the window to build it well is much shorter than most people think.

In this guide we cover: what the microbiome is, how it builds from birth, how to recognise when it needs support, and what to do to protect it day to day.

What is the gut microbiome and why does it matter so much in children?

The gut microbiome is the community of billions of bacteria living in your child's intestine. Far from being harmful, the vast majority of these bacteria are essential to their health.

In children, the microbiome plays three fundamental roles:

Digestion: it breaks down nutrients from food and makes them available for the body to absorb and use.

Immunity: the gut-associated lymphoid tissue (GALT) concentrates approximately 70% of the body's immune cells. From the first months of life, the gut microbiome plays a central role in educating this system: it teaches immune cells to tolerate what is harmless and to respond to what is threatening. A diverse, balanced microbiome is therefore one of the pillars of a child's immune development.

Protection: the gut microbiome plays an active protective role. By occupying sites on the intestinal lining and producing antimicrobial substances, it limits the proliferation of pathogenic bacteria. This role is particularly critical in young children, whose intestinal barrier is still maturing and whose microbiome is still being built during the early years of life.

What makes childhood so critical is the timing. The microbiome begins building from birth and reaches a relative stability around age 3 to 4. The quality and diversity of the microbiome established during this window has consequences that extend throughout a child's entire life. The good news: it can always be supported and improved, whatever your child's age.

What recent research tells us

In November 2025, INRAE and AP-HP launched Le French Gut Kids: the first national French research project dedicated to mapping the gut microbiome of children and adolescents aged 3 to 17. The project aims to collect samples from 10,000 children by 2029.

Until recently, very little was known about what actually happens in a child's gut. French scientists are only now beginning to map it for the first time. The project will specifically study how diet, lifestyle, and environment shape microbiome diversity during childhood and adolescence: exactly the period when chronic conditions, including allergies, obesity, and digestive disorders, are increasing most rapidly in young people.

This is the most significant French research initiative on children's gut health currently underway. It confirms what pediatric nutritionists observe in practice every day: what happens in your child's gut during childhood matters far more than was previously understood.

The first 1,000 days: a crucial but not irreversible window

You may have heard of the concept of the "first 1,000 days": from conception to age 2. This period is recognised as particularly important for microbiome construction. The mode of delivery, breastfeeding, the environment, and early food choices all shape the foundations of your child's gut health, with effects lasting a lifetime.

But here is what matters: this is not a window that closes and locks. The microbiome continues building, evolving, and responding to care throughout childhood and adolescence. Regardless of how your child was born, whether they were breastfed or not, and whatever antibiotic courses they may have had: their microbiome can always be nourished, diversified, and strengthened. It is never too late to start.

How to tell if your child's microbiome needs support

A disrupted microbiome does not always announce itself loudly. More often it shows up quietly, in things parents notice day to day but do not immediately connect to gut health.

The most common signs to watch for in children: your child catches every cold going around, even outside of winter. Their stomach hurts regularly, especially in the mornings or before school. Their skin breaks out in eczema or reactive patches that keep coming back. Their transit is irregular: constipated one week, loose stools the next. They seem more tired, more irritable, or more anxious than usual without a clear reason.

If several of these are present at the same time and have been going on for a while, the microbiome is worth looking at. It is rarely the first place parents think to look, but it is often where the answer is. The AFPA confirms that microbiome imbalance in children is more common than people think and increases with the number of antibiotic courses received.

6 factors that damage your child's gut microbiome

Understanding what harms the microbiome is just as important as knowing what builds it. Several modern habits quietly deplete your child's microbial diversity every day.

1. Ultra-processed food

Diets rich in refined sugars, additives, and poor-quality fats while being low in fibre impoverish bacterial diversity and favour opportunistic bacteria. When reading food labels, the shorter the ingredient list, the better. Be cautious of any ingredient beginning with E followed by a number, refined sugar in any form, sweeteners, and poor-quality fats. In general, if you cannot identify all the ingredients on a label, the product is likely to be problematic for the microbiome.

2. Excess sugar

Sugar feeds undesirable bacteria, causing imbalance, bloating, and chronic low-grade inflammation. The most problematic forms are glucose-fructose syrup, white sugar, fructose syrup, and corn syrup. Watch for hidden sugars in breakfast cereals, biscuits, sweetened drinks, and flavoured yogurts: this is where the majority of hidden sugar accumulates in children's diets.

3. Repeated antibiotics and PPIs

Antibiotics are life-saving medicines but they do not distinguish between pathogenic and beneficial bacteria: they eliminate both. The consequences are a significant reduction in bacterial diversity, the disappearance of key strains, and a weakening of the gut's protective lining.

A study published in Nature Communications showed that certain microbiome changes can persist for several months after a single antibiotic course. A Harvard study also confirmed that antibiotic-related microbiome disruption in babies has measurable long-term consequences. This is precisely why actively supporting the microbiome during and after every antibiotic course makes such a meaningful difference: the sooner you act, the faster it recovers.

Proton pump inhibitors (PPIs), sometimes prescribed for infant reflux, can also affect microbiome balance. If your child has taken PPIs, supporting the microbiome with probiotics and prebiotic-rich foods is a simple and effective step.

4. Lack of fibre

Fibres are the fuel of the microbiome. They feed good bacteria and allow the production of short-chain fatty acids essential for gut health and immune function.

The formula to remember: your child's daily fibre needs equal their age plus 5 grams per day. A 5-year-old needs approximately 10 grams of fibre daily. A 9-year-old needs 14 grams. Most children in France do not reach this level. Constipation is often the first consequence of insufficient fibre intake in children. 

5. Food additives

Certain emulsifiers, preservatives, and sweeteners alter microbiome composition and weaken the gut's protective lining. When reading labels, here is what to watch for: emulsifiers to limit are E466, E433, E471. Preservatives to limit are E211, E202, E250, E621.

6. Lifestyle factors

The microbiome is sensitive not just to what your child eats but to how they live.

Contact with nature: children who play regularly outdoors, in the earth, and with animals are exposed to a wider diversity of bacteria. This exposure supports the development of a diverse, resilient immune system.

Sleep: the microbiome follows the body's daily rhythm. Regular, good-quality sleep supports microbiome balance, and a healthy microbiome in turn supports better sleep.

Physical activity: movement supports a more diverse and resilient microbiome. Outdoor play, even 20 minutes a day, makes a meaningful difference.

6 foods that nourish your child's gut microbiome

Supporting your child's microbiome through food is both effective and accessible. These six foods are the most impactful.

1. Sauerkraut and fermented vegetables

Non-pasteurised sauerkraut is rich in live beneficial bacteria, particularly lactobacilli, which reinforce gut diversity. The key detail: non-pasteurised. Heat destroys the live bacteria that make fermented foods beneficial. Variants your child might accept: milder versions of kimchi, miso dissolved in soups, tempeh as a protein source.

2. Garlic and the prebiotic family

Garlic is rich in inulin, a type of fibre that feeds the good bacteria already present in the gut. It does not add bacteria itself: it feeds the ones already there. Variants with similar properties: onion, leek, asparagus, artichoke.

3. Jerusalem artichoke: the prebiotic powerhouse

Jerusalem artichoke is particularly rich in prebiotic fibres that specifically promote bifidobacteria, the beneficial bacteria most important during childhood. It also reduces pathogenic bacteria and directly supports transit regularity. Variants: chicory root, salsify.

4. Natural yogurt and kefir

Natural yogurt contains live bacteria that directly enrich the gut microbiome. The key detail: the yogurt must not be pasteurised after fermentation, as this kills the live cultures. Check the label for "contains live cultures."

Kefir is even richer: a fermented drink containing up to 10 different beneficial bacterial strains, it is one of the most potent natural probiotic foods available for children.

5. Slightly unripe bananas

Slightly unripe bananas contain resistant starch, a type of fibre that feeds beneficial gut bacteria. As bananas ripen, the resistant starch converts to sugar and the benefit decreases. The greener the banana, the stronger the effect.

6. Mushrooms, cranberry, and other allies

Certain mushroom varieties, particularly reishi, maitake, shiitake, and oyster mushrooms, contain compounds that support microbiome diversity and immune function.

Cranberry contains a non-digestible compound from the xyloglucan family that acts as a prebiotic and specifically promotes the growth of a beneficial Bifidobacterium strain: a lesser-known but particularly interesting ally for children.

Lentils provide both fibre and plant protein and directly support microbiome diversity. They are one of the most underrated foods for children's gut health.

Probiotics vs prebiotics: what is actually the difference?

These two words are often used interchangeably but they describe completely different things, and understanding the difference helps you make better choices for your child every day.

Probiotics are living bacteria: the good bacteria themselves. They help digest food, synthesise vitamins, fight harmful bacteria, reinforce natural defences, and protect the gut. You find them naturally in yogurt, kefir, non-pasteurised sauerkraut, and miso.

Prebiotics are fibres that the body cannot digest but that serve as food for the good bacteria. Without prebiotics, probiotic bacteria cannot establish themselves and stay active. You find them in slightly green bananas, garlic, onion, leek, apples, and whole grains.

Together they form what scientists call a synbiotic: a combination where the whole is greater than the sum of its parts. Think of it this way: probiotics are the seeds you plant in the garden, and prebiotics are the water and sunlight that make them grow and thrive. This is why a probiotic formula that also contains prebiotic fibres, like our Kids 10 Billion Probiotics, delivers significantly better results than probiotics alone.

According to the Canadian Digestive Health Foundation, targeted probiotic supplementation can reduce the duration of acute diarrhoea by 20 to 30% in children.

Diarrhoea and the microbiome: what parents need to know

Diarrhoea in children is one of the most common signs that the gut is under stress, whether from a viral infection, a dietary change, or an antibiotic course. It is the body's way of signalling that gut balance needs support.

The right actions during a diarrhoea episode: hydration first, with water, clear broths, or rehydration solutions such as those recommended by your pharmacist. This is the priority before anything else.

Gentle foods that support recovery include rice, cooked carrots, banana, grated apple, and steamed potato. These foods are gentle on the stomach, help stools become more regular, and do not irritate the gut.

Supporting gut flora is essential: probiotics, particularly bifidobacteria, help restore the gut barrier and reduce the duration of diarrhoea episodes. Starting child-appropriate probiotics on the first day can meaningfully shorten recovery time.

What to avoid during and after the episode: fatty, sugary, or ultra-processed foods. These feed disruptive bacteria and slow recovery.

If diarrhoea lasts more than 2 to 3 days or your child seems unwell, consult your paediatrician.

The gut-brain axis: how your child's gut affects their behaviour

The intestine is often called the "second brain," and for good reason. Via the gut-brain axis, a direct communication channel between gut and brain, the microbiome directly influences serotonin production, emotional regulation, and attention capacity. Approximately 95% of the body's serotonin is produced in the gut.

A balanced microbiome means a calmer and more concentrated child. This is why children with digestive discomfort are often also more irritable, more anxious, or struggle to focus at school. The connection is not coincidental: the gut and brain are in constant conversation.

Emerging research suggests the microbiome may also play a role in neurodevelopmental challenges like ADHD via this gut-brain connection. Certain probiotic strains, particularly Lactobacillus helveticus, Bifidobacterium longum, and Lactobacillus rhamnosus, are being studied for their potential to support mood regulation, stress reduction, and attention in children. This research is still emerging and probiotics do not replace usual medical treatment. Always discuss with your doctor before using probiotics as a complement to any medical treatment for your child.

When and how to give your child probiotics

Probiotics are beneficial year-round but certain moments deserve particular attention.

During and after antibiotics, this is the most important use case. Start probiotics on day 1 of antibiotic treatment and space the intake by at least 2 hours from the antibiotic dose. Continue for at least 1 month after the course ends, or 2 months if the course lasted more than 7 days. 

During repeated fatigue, colds, or convalescence, when your child keeps catching every virus, the microbiome is often a factor. A targeted probiotic cure supports the immune system's natural defences.

At back to school in September, the start of the school year can be a challenge for the gut: new bacteria, stress, rhythm change. A September preventive cure with Bifidobacterium longum and Bifidobacterium infantis, combined with acacia prebiotic fibres, helps reinforce your child's first line of defence before winter viruses arrive. Ideal duration: the entire month of September.

From the youngest age, from 1 year, a probiotic formula adapted to children supports the microbiome during its most critical development phase and can help reduce colic and mild digestive discomfort.

A 3-month cure helps the body find its natural balance gradually and durably. Punctual support, during antibiotics or at back to school, is shorter and more targeted. The two approaches serve different purposes and complement each other.

How to choose a probiotic for your child

The number of strains: most children's probiotics contain 2, 3, or 4 strains. A formula with 7 different complementary strains provides broader action across immunity, digestion, and transit.

The CFU count: CFU (Colony Forming Units) measures live bacteria per dose. 400 million is insufficient. 1 billion is modest. 10 billion per dose is the level that delivers meaningful results.

Zero additives: most probiotic powders are up to 90% fillers and additives. The bacteria and prebiotic fibres should be the formula, nothing more. Zero sugar, zero additives, zero maltodextrin.

The capsule format: the capsule guarantees bacterial survival through heat and humidity. A capsule that opens easily and mixes into water or yogurt means no additives are needed to make it palatable for young children.

Our Kids 10 Billion Probiotics bring together all of these criteria: 7 carefully selected strains, 10 billion CFU per capsule, acacia prebiotic fibres included, zero sugar, zero additives, zero maltodextrin. From 1 year.

Your daily checklist to support your child's microbiome

These are the habits that make the biggest cumulative difference, applied consistently every day:

At least one portion of fibre-rich food at every meal: vegetables, legumes, whole grains, fruits with skin.

At least one prebiotic food daily: garlic or onion in cooking, slightly green banana as a snack, oat flakes at breakfast.

One fermented food daily if possible: natural yogurt at breakfast or as a snack, kefir as a drink.

Sufficient hydration: water as the primary drink, adapted to age (1.2 to 1.6 litres per day).

Outdoor play, even 20 minutes a day, meaningfully supports microbiome diversity.

A consistent bedtime routine: regular sleep supports microbiome balance.

During and after every antibiotic course: start probiotics on day 1, space by 2 hours, continue 1 to 2 months after.

Frequently asked questions

From what age can I give my child probiotics?
From 1 year for most children's probiotic supplements. For babies under 1 year, specific infant probiotics exist. Always check the product's age recommendation and consult your paediatrician.

Can probiotics be given every day?
Yes. Probiotics are not medicines: they are living bacteria that support the gut's natural balance. A 3-month daily cure supports gradual microbiome rebalancing. Shorter targeted courses address specific situations: antibiotics, back to school, frequent illness.

Do supermarket yogurts contain real probiotics?
Only if they contain live cultures not heat-treated after fermentation. Look for "contains live cultures" on the label. Flavoured yogurts and those with a long shelf life have often been pasteurised after fermentation: the bacteria are no longer alive.

How many strains should a good children's probiotic contain?
At least 5 to 7 complementary strains targeting immunity, digestion, and transit. A formula with 7 strains including Bifidobacterium lactis, Bifidobacterium longum, Lactobacillus acidophilus, Lactobacillus gasseri, Lactobacillus plantarum, Lactobacillus rhamnosus GG, and Lactobacillus reuteri covers the full spectrum of children's gut health needs.

What are the signs that my child's microbiome needs support?
The most common signs are frequent colds or infections, recurring stomach aches, irregular transit, persistent eczema, unexplained fatigue, and irritability or mood changes without a clear cause. If several of these are present at the same time over a period of weeks, the microbiome is worth supporting.

Can gut health affect my child's behaviour and concentration?
Yes. Via the gut-brain axis, the microbiome directly influences serotonin production and emotional regulation. Children with a disrupted microbiome are often more irritable, more anxious, and struggle more to concentrate. Supporting gut health is increasingly recognised as an important part of supporting children's mental and emotional wellbeing.

Should I give probiotics at back to school?
September is one of the most valuable moments for a probiotic cure. Back to school means massive exposure to new bacteria, stress, and rhythm disruption. A September preventive cure with Bifidobacterium longum and Bifidobacterium infantis combined with acacia prebiotic fibres helps reinforce the first line of defence before winter viruses arrive.

My child has had several antibiotic courses: is it too late to support their microbiome?
It is never too late. The microbiome is resilient and responds well to support at any age. Starting probiotics for children, increasing prebiotic-rich foods, and reducing sugar and ultra-processed foods will make a meaningful difference regardless of your child's history.

What parents should know

The gut microbiome builds primarily during the first years of life, but it can be supported, strengthened, and improved at any age.

70% of the immune system is located in the gut: a healthy microbiome is the foundation of your child's natural defences.

The signs that a microbiome needs support are often everyday observations: frequent colds, stomach aches, irregular transit, eczema, fatigue, and irritability. It is rarely the first place parents look, but it is often where the answer is.

Ultra-processed food, excess sugar, repeated antibiotics, lack of fibre, food additives, and too little outdoor time all deplete the microbiome.

Fermented foods (yogurt, kefir, sauerkraut), prebiotic-rich foods (garlic, banana, leek, cranberry), and fibre-rich foods (legumes, whole grains) are the most powerful daily dietary tools.

Probiotics and prebiotics work best together: this combination is called a synbiotic. A formula with 7 strains, 10 billion CFU per dose, prebiotic fibres, and zero additives delivers the most complete support. Discover our Kids 10 Billion Probiotics.

A 3-month cure supports gradual microbiome rebalancing. Targeted shorter cures address specific situations: antibiotics, back to school, frequent illness, digestive discomfort.

Are you wondering about magnesium deficiency and its health effects? This international scientific review provides an update on the latest available data, causes, consequences, and solutions.

Magnesium is an essential mineral involved in energy metabolism, glucose regulation, cardiovascular function, bone integrity, and neuronal activity. Despite its fundamental physiological roles, dietary magnesium deficiency remains a widespread and largely underestimated global public health problem.

Globally, an estimated 2.4 billion people, or approximately 31% of the population, do not meet recommended magnesium intake levels.

This deficiency results from multiple converging factors, including modern dietary habits poor in whole grains and vegetables, soil depletion due to intensive farming, losses related to food processing, population aging, chronic diseases, and socio-economic inequalities.

The health consequences are significant: magnesium deficiency is associated with an increased risk of cardiovascular diseases, metabolic disorders, bone loss, and neuropsychiatric disorders.

The biological and physiological roles of magnesium

Magnesium is an essential mineral, vital for a wide range of biochemical and physiological processes, including energy metabolism, protein and nucleic acid synthesis, muscle contraction, neuronal activity, glucose regulation, and blood pressure control.

In the brain and nervous system, magnesium plays a crucial role in modulating ion channels and neurotransmitter release, thereby influencing neuronal excitability and synaptic plasticity. It protects neurons by regulating NMDA receptor activity, highlighting its importance in neuroprotection and cognitive processes.

Several meta-analyses have highlighted significant associations between magnesium status and various neurological or psychological health parameters.

Like calcium, magnesium is fundamental for muscle and bone health. Beyond its role as a mere storage site, bone tissue actively participates in magnesium homeostasis, while magnesium, in turn, exerts significant regulatory effects on bone mineralization.

Furthermore, magnesium influences the immune system and could play a regulatory role in inflammation.

To specifically understand what these roles mean for your child's health — sleep, concentration, growth — consult our full article: Magnesium in children: role, needs, and deficiencies

Factors contributing to magnesium deficiency

Multiple factors, acting independently or in combination, contribute to magnesium deficiency. These include dietary habits, lifestyle behaviors, physiological or pathological conditions, agricultural practices, and environmental influences such as climate change.

Modern diets, rich in refined grains, added sugars, and processed foods, are generally poor in magnesium. Processing and cooking, especially boiling certain vegetables, can lead to a loss of 80 to 90% of their magnesium content. Refining whole grains can also remove up to 80% of their magnesium content.

Soil depletion: intensive farming and the excessive use of synthetic fertilizers have significantly depleted soils of magnesium, thereby reducing the natural content of the foods we consume.

Major health consequences of magnesium deficiency

Magnesium acts as a cofactor for hundreds of enzymatic reactions essential for the proper functioning of the body. Its deficiency is implicated in the development of type 2 diabetes, cardiovascular diseases, hypertension, and osteoporosis.

Although these pathologies are multifactorial, chronic low-grade inflammation and oxidative stress induced by magnesium deficiency can worsen their underlying pathophysiology.

In Europe, numerous studies show insufficient magnesium intake across different age groups. An analysis of the NutriNet-Santé cohort among French adults showed that, among 13,549 men not taking dietary supplements, the prevalence of insufficient magnesium intake was 53.2%, and 51.6% among 30,197 women.

Strategies to prevent and correct magnesium deficiency

Managing magnesium deficiency requires a multidimensional strategy.

Dietary strategies: dietary modification remains the basis for correcting magnesium insufficiency in the general population. It is advisable to increase the consumption of magnesium-rich foods:

• Leafy green vegetables (e.g., spinach)
• Legumes (e.g., black beans, lentils)
• Nuts and seeds (e.g., almonds, pumpkin seeds)
• Whole grains (e.g., brown rice, oats)
• Certain fruits and seafood

For the general population with insufficient intake, oral magnesium supplements are a convenient way to maintain adequate levels. Consulting healthcare professionals helps determine the optimal dosage and monitor magnesium status.

The bioavailability and digestive tolerance of magnesium vary depending on the forms used: organic salts, such as magnesium citrate, lactate, and bisglycinate, generally offer better absorption than inorganic forms like magnesium oxide.

Conclusion

Magnesium is one of the pillars of human health, yet its deficiency remains a widespread and largely underestimated global problem. The global burden of magnesium deficiency results from a complex interaction between insufficient dietary intake, environmental degradation, depletion of agricultural soils, and socio-economic inequalities.

Concrete strategies are needed to mitigate this deficiency, including improving dietary intake through diversification, food fortification, optimizing agricultural practices, strengthening public awareness, and integrating magnesium screening into health protocols for at-risk populations.

Magnesium in children: understanding its role, children’s needs, and preventing insufficient intake

Magnesium is involved in over 300 enzymatic reactions, making it an essential mineral for the proper functioning of a child's body. It plays a particular role in energy, the nervous system (stress and emotion management), sleep, concentration, and immunity, all functions that are particularly active during growth.

Modern diets can sometimes lead to insufficient intake.

What signs might suggest a magnesium deficiency in children?

Persistent fatigue, difficulty falling asleep, agitation at the end of the day, muscle cramps, or concentration difficulties can sometimes indicate insufficient magnesium intake. These signs are frequently observed during periods of rapid growth, after a viral episode, or during periods of stress.

Are biological markers useful?

Magnesium levels are generally measured in the blood (serum magnesium).
However, this only reflects a very small part of the body's reserves (about 1%).

Result: a normal blood level does not rule out a deficiency.

Other markers (erythrocyte or intracellular magnesium) are more relevant but rarely used in practice.

In reality, the evaluation is mainly based on:

• signs (fatigue, irritability, sleep...)
• the child's context

If in doubt, consult a healthcare professional.

Why is magnesium important for children?

Magnesium is involved in over 300 enzymatic reactions in the body. In children, it plays a key role in the development of the nervous system by participating in nerve transmission and regulating neuronal excitability, thus contributing to emotional balance, concentration, and stress management.

It is also essential for muscle function, promoting relaxation and limiting tension, cramps, or physical agitation in case of deficiency.

Furthermore, it contributes to sleep quality by facilitating falling asleep and supporting recovery.

Finally, it is involved in energy production (ATP) and protein synthesis, two processes essential for a child's growth and development.

Our KIDS MAGNESIUM +CACAO provides 245 mg of magnesium, in a natural organic cocoa base, suitable for children.

The role of magnesium in children's sleep

Magnesium plays an indirect but important role in sleep regulation.

It is notably involved in the functioning of the nervous system by promoting a state of relaxation and limiting neuronal hyperexcitability. This effect helps create conditions conducive to falling asleep.

Furthermore, magnesium participates in the regulation of certain neurotransmitters involved in sleep, such as GABA, which promotes calmness, as well as the balance of the stress response system.

In children, an insufficient intake of magnesium can therefore manifest as:

• difficulty falling asleep
• restless sleep
• night awakenings

However, it is important to note that magnesium is not a treatment for sleep disorders, but a nutritional support that can help improve overall balance when signs of insufficient intake are present.

Magnesium, agitation and attention disorders in children

Agitation and difficulty concentrating are common concerns for parents. Some data suggest that insufficient magnesium status may be associated with increased agitation and attention disorders.

Magnesium contributes to normal psychological function and is involved in the regulation of the nervous system. Sufficient intake therefore contributes to the child's nervous balance, especially during periods of stress or high cognitive demand.

However, this is not about treating a medical disorder. In case of suspected ADHD or attention disorders, the advice of a health professional remains essential.

What are the magnesium requirements by age?

Needs evolve with age, growth, and activity level.

These magnesium intakes recommended by ANSES vary by age and correspond to levels deemed sufficient to cover the needs of most children. However, these needs can change depending on the individual context, especially during periods of growth or stress.

In which foods is magnesium found?

Animal sources of magnesium

Plant sources of magnesium

What is the best form of magnesium for children?

Not all forms of magnesium have the same bioavailability or digestive tolerance.

Some forms are particularly well suited for children, such as magnesium from natural sources (e.g., sea lettuce), as well as organic forms such as bisglycinate, malate, or magnesium citrate, which are generally better absorbed and tolerated.

Conversely, forms like oxide, sulfate, or magnesium chloride have more limited absorption and can cause digestive discomfort.

Furthermore, magnesium absorption can be reduced when consumed simultaneously with other minerals like calcium or iron.

A natural solution to supplement intake

When diet does not cover a child's magnesium needs, appropriate supplementation can be considered.

With this in mind, we have formulated a supplement combining 245 mg of magnesium in citrate form, known for its good bioavailability, with a natural base composed of organic cocoa powder, organic almond powder, and inulin fibers from chicory.

This form has been designed to be suitable for children, both well-tolerated and easy to integrate into their daily routine.

Important information

A dietary supplement should not replace a varied, balanced diet.
Follow the recommended dosage.
Before giving any supplement to a child, seek advice from a pediatrician or healthcare professional.

Omega 3s are essential fatty acids for our children, but to fully benefit from their advantages, it is crucial to understand some key aspects: the purity of the oils, the prevention of oxidation and the importance of the TOTOX test.

Omega-3s for children: role, importance and recommendations

Why is the purity of the oil essential?

Omega-3s, particularly ALA (alpha-linolenic acid) and DHA (docosahexaenoic acid), are polyunsaturated fatty acids that are particularly sensitive to oxidation, which can be promoted by heat, light, and exposure to oxygen.

Furthermore, the presence of contaminants such as heavy metals or pesticide residues does not directly affect their nutritional properties, but constitutes an independent health risk, highlighting the importance of the quality and purity of the oils consumed.

When choosing an oil rich in Omega 3, always opt for certified pure products, from traceable sources and having undergone rigorous testing to eliminate any form of contamination.

At Nuré, our Omega 3 DHA comes from a micro-alga and not from fish oil and is free of all heavy metals.
Omega 3 ALA is derived from organic chia and rapeseed oil, all blended with organic extra virgin olive oil.

Oxidation: an invisible but formidable enemy

Omega-3 fatty acids are highly susceptible to oxidation, a chemical process that degrades their molecules when exposed to oxygen, heat, or light. When the oil oxidizes, it loses its anti-inflammatory properties and can even produce compounds harmful to your body.

How to prevent the oxidation of Omega 3?

It is recommended to:

• Choose quality oils that have been tested, in particular using the TOTOX test with a result of less than 10.
• Choose oils packaged in opaque glass containers.
• Store the oils away from light and in a cool place (refrigerate after opening).
• Consume the oils within the indicated time frame to prevent them from going rancid.
• Avoid unnecessary ingredients such as flavorings or colorings that can promote the oxidation of Omega 3.

Do not buy your Omega 3 in gummies. They are heated to form them, which is something Omega 3 should absolutely not be done.
It also contains other ingredients that are incompatible with Omega 3, as well as a dosage that is too low, making them useless for obtaining real benefits.

Omega-3 for children: Not all omega-3 supplements for children are created equal

At Nuré, we only put the essentials in our Omega 3 oil: vegetable oils and a rosemary-based antioxidant, and that's all.

The TOTOX test: a guarantee of quality

How can you tell if an oil is pure and unoxidized?
The TOTOX test is a key quality indicator for Omega 3 rich oils.

It measures the degree of oxidation of the oil by combining two parameters:

• The quantity of peroxides (products of the first oxidation phase)
• Secondary compounds formed by advanced oxidation

The lower the TOTOX score, the better the quality of the oil.
Ideally, a high-quality oil should have a score of less than 10 (the limit being set at 26).

At Nuré, we carry out this test on each batch to ensure the quality of our oil and offer the best to our children.

The benefits of Omega-3s are well preserved.

When you consume high-quality, unoxidized Omega-3s, you can fully benefit from their properties:

• Support for cognitive function
• Reduction of inflammation
• Immune system strengthening
• Improvement in cardiovascular health

Our Vegan Omega 3 oil will provide your child with the essential DHA for their brain, mood, and overall well-being. Fish oil free, guaranteed heavy metal free.

Discover our Omega-3 for children

The majority of products available on the market do not provide the recommended daily intake of 250 mg of DHA. Many are formulated with fish oil, which has a significant environmental impact , and sometimes contain additives, sugar, or colorings. In many cases, neither the purity nor the stability of the oils is guaranteed, particularly in the absence of TOTOX testing, which is not mandatory.

Omega-3s are essential to support your child’s brain development, focus, and emotional balance all year long.

Adjusting intake according to fish consumption
- If your child eats 2 to 3 servings of fatty fish per week (such as sardines, mackerel, or herring), no additional DHA intake is necessary.
- If they eat around one serving per week, we recommend a supplement of 250 mg of DHA three times a week.
- And if fatty fish are rarely on the menu, a daily intake of 250 mg of DHA is the best way to ensure a consistent supply.

Why is it important to choose the right forms?

Better absorption, better results
High-quality forms ensure optimal absorption, allowing the body to fully benefit from each nutrient.

Fewer side effects
Some forms can cause digestive discomfort, for example, magnesium oxide (diarrhea) or iron sulfate (stomach pain). Choosing gentler forms, like bisglycinate, reduces these risks.

Less waste for the body
When nutrients are poorly absorbed, the body eliminates them, putting extra strain on filtration and detoxification organs.

Better bioavailability
Active forms, such as methylcobalamin for vitamin B12, are directly usable by the body, unlike inactive forms that require conversion.

Ideal for children and sensitive individuals
Children, the elderly, and those with digestive issues often absorb certain forms less efficiently. Choosing highly bioavailable nutrients ensures they receive their full benefits.

A recent 2024 study (National Library of Medicine) confirms a concerning decline in the nutritional quality of our food over the past 60 years. Essential minerals and nutrients found in fruits, vegetables, and staple crops have significantly decreased due to modern farming methods and soil depletion.

For parents, this means that even a balanced diet may no longer be enough to fully meet children’s nutritional needs. Choosing high-quality supplements can help fill these gaps and support their long-term health.

Why Is This Happening?
Several factors contribute to the decline in food nutrition:

• Crop Selection & Farming Practices – Preference for high-yield, less-nutritious varieties has reduced nutrient density in food.
• Increased CO₂ Levels – Rising carbon dioxide in the atmosphere has been linked to a decline in the nutritional quality of fruits, vegetables, and staple crops.
• Soil Depletion – Intensive chemical use in agriculture depletes soil minerals, impacting the food grown in it.
• Longer Food Supply Chains – The time between harvest and consumption has increased, leading to vitamin loss.
• Early Harvesting – Fruits and vegetables are often picked before they fully mature, preventing them from reaching peak nutrient concentration.
• Overcooking – Excessive cooking further destroys the already reduced micronutrient content in food.

We believe that food supplements can play a valuable role in bridging nutritional gaps and supporting healthy physical and cognitive development in children.

But be mindful when choosing supplements! Avoid those containing additives, artificial colorings, artificial flavors, or refined sugars—these can be counterproductive.

At Nuré Nutrition, we are committed to providing natural formulations with zero compromise on quality and effectiveness. 🌿

Adopting a balanced diet from a young age is essential for supporting growth, cognitive and emotional development, strengthening immunity, improving sleep quality, and establishing healthy habits that will last a lifetime. Here are some tips that I hope will be helpful for the whole family!

1. Water: the best mealtime ally

Encourage your children to drink water with meals. Unlike juices or sugary drinks, water hydrates without adding unnecessary sugar or calories. It doesn’t affect blood sugar and promotes good digestion. It's important to drink water throughout the day, not just at mealtime.

2. A balanced and colorful plate with vegetables

Fill half the plate with a variety of vegetables at each meal. Vegetables, rich in fiber, vitamins, and minerals, support digestive health and strengthen the immune system. Varying colors provide a range of nutrients: green vegetables are high in iron and fiber, orange ones in beta-carotene, and red vegetables in antioxidants.

3. Protein and fats at breakfast to start the day right

A breakfast containing protein (such as eggs, yogurt, or nuts) and healthy fats (like vegetable oils, avocado) helps stabilize energy levels and prevent cravings. This type of breakfast improves concentration and cognitive performance, helping kids stay focused at school.

4. Teaching chewing skills

Encourage children to take their time chewing. Digestion begins in the mouth with enzymes like amylase, which break down carbohydrates and aid nutrient absorption. Taking time to chew well also helps children savor flavors and reach a natural feeling of fullness.

5. Raw fruits and vegetables as healthy snacks

To deal with hunger between meals, opt for raw fruits and vegetables. Low in calories yet rich in fiber, vitamins, and minerals, they help satisfy small hunger pangs without excess. For example, carrots, cucumber slices, or an apple make excellent choices.

6. Daily goal: five fruits and vegetables, or more!

Set a goal of at least five servings of fruits and vegetables per day, ideally seven to eight. This habit is essential for fiber, vitamins (A, C, E), and minerals (potassium, magnesium). A high intake of fruits and vegetables is associated with reduced risks of chronic diseases like type 2 diabetes and obesity.

7. Choose high-quality oils

Use vegetable oils rich in essential fatty acids to add to meals. Camelina and flaxseed oils, rich in omega-3s, support brain development and help regulate inflammation. Olive oil, high in omega-9, is also excellent for cardiovascular health.

8. Add a handful of nuts daily

Nuts (walnuts, almonds, hazelnuts) are a source of healthy fats and protein. They also provide minerals like magnesium and calcium, which support bone health. A small handful a day helps meet nutritional needs without adding saturated fats.

9. Include fish twice a week

Incorporate fish into meals at least twice a week, choosing small, fatty fish like sardines or mackerel. They are rich in omega-3s, which support cognitive and visual health, and are less likely to accumulate pollutants than larger fish.

10. Avoid refined sugars for stable energy

Refined sugars in processed foods have a high glycemic index, causing blood sugar spikes followed by sudden drops. This can lead to fatigue, irritability, and cravings. By reducing their intake, you help children maintain more stable energy levels and support a healthy gut microbiome.

11. Prioritize homemade meals over ultra-processed foods

Ultra-processed foods often contain additives, preservatives, and low-quality ingredients. They are generally low in nutrients and high in sugar, saturated fats, and salt. Preparing homemade meals lets you control ingredient quality, ensuring a balanced intake of essential nutrients.

12. Limit processed meats and red meat

Red meats (beef, pork) and processed meats are high in saturated fats and can contribute to inflammation when consumed in excess. Limit intake to two servings per week to promote cardiovascular health and reduce exposure to additives found in processed meats.

13. A fresh fruit at snack time to boost fiber and vitamins

Including a whole, fresh fruit at each snack time is a simple habit to add fiber, vitamins, and minerals to your kids' daily diets. Whole fruits (rather than juices) enhance fullness and provide essential fiber for digestion.

By adopting these principles, you will help establish a strong foundation for your child's health. These simple practices not only support harmonious growth but also build habits that will last into adulthood.
