Our guide to children’s gut health

Have you ever noticed your child’s moods shifting like the wind, meltdowns at twilight, restless nights, skin rashes out of nowhere? Modern science now shows what ancestral wisdom has long known... these outward signs often begin deep within the gut.

Gut dysbiosis in children can look like:

Tantrums and mood swings that seem to flare without warning
Skin issues like eczema, rashes, or unexplained hives
Digestive troubles: constipation, bloating, and tummy aches that won’t quit
ADHD-like symptoms: fidgeting, trouble focusing, a mind that never settles

These are not “bad behaviours”, they’re the gut crying out for balance. Inflammation in the gut lining, sparked by modern foods and environmental stressors, can let immune triggers slip through. The result? An immune system stuck on high alert, a brain flooded with stress signals, and a child whose calm is buried under the noise.

The good news? Children are remarkably resilient. And their gut is incredibly adaptive when given the right roadmap.

Why gut health is everything in childhood

The gut sets the tone for almost everything in a child’s development. Here’s why it matters so deeply:

The gut-brain axis: A superhighway of nerves and signals connecting the gut to the brain, influencing everything from focus to calmness.
Neurotransmitter production: The gut microbiome produces serotonin and GABA, the very chemicals that soothe and steady our minds.
Immune regulation: A healthy gut teaches the immune system to respond appropriately, reducing allergies, sensitivities, and inflammation.
Nutrient absorption: Every cell-building, hormone-balancing, brain-feeding nutrient? It’s absorbed in the gut.

When the gut is nurtured, children are more likely to have steady energy, balanced moods, and a spark of curiosity.

But when it’s under siege, by refined sugars, seed oils, additives, antibiotics, things shift. The gut gets leaky. The brain gets foggy. And kids start to struggle.

The microbiome’s first birthday

A baby’s birthday is also the birthday of their independent microbiome. As the mother’s body labours to bring forth new life, it also performs an ancient microbial dance. During a vaginal birth, the baby is bathed in microbes from the birth canal, a messy, miraculous first inoculation that coats the newborn’s skin, eyes, mouth, and gut. This is nature’s intended welcome committee for the infant immune system.

Breastfeeding extends this gift. Far more than nutrition, mother’s milk is alive, teeming with beneficial bacteria, enzymes, and special sugars designed to nourish the infant’s newly seeded microbiome.

Breast milk is effectively “feeding the friends”, promoting the growth of beneficial microbes that, in turn, protect and nourish the baby. It’s a symbiotic relationship between mother, baby, and microbiome. Breast milk also carries maternal antibodies (IgA, etc.), immunoglobulins, antimicrobial proteins, and even maternal immune cells that patrol the baby’s gut, all of which work together to prevent infection and inflammation while the infant’s own immune system mature.

But what if breastfeeding isn’t possible?

Life doesn’t always unfold like you want it to. Even when breast milk isn’t an option, raw milk and colostrum can be allies as children grow. Raw milk, unprocessed and enzyme-rich, is closer to what a baby’s biology expects: a living food filled with beneficial bacteria, immunoglobulins, and bioavailable nutrients. When bottle-feeding, practice skin-to-skin contact (bare chest cuddling) , nature’s quiet bridge, offering microbial exposure and warmth that mimic nursing.

Four key nutrients to nourish the young gut

1. Raw milk

Raw milk is one of the most nourishing, bioavailable foods for children’s gut health, and it’s no coincidence. Its composition closely mirrors that of human breast milk, making it a natural bridge from infancy to childhood.

Living enzymes: Raw milk contains lactase and lipase, enzymes that help children break down milk sugars and fats more easily, reducing digestive distress that many experience with pasteurised dairy.
Probiotic microflora: Unlike pasteurised milk, raw milk teems with beneficial bacteria like Lactobacillus and Bifidobacteria, seeding the gut with friendly microbes that support immunity and calm inflammation.
Immunoglobulins and lactoferrin: These immune-modulating proteins in raw milk act like quiet guardians, soothing the gut lining and regulating immune responses, much like the protective factors found in breast milk.
Bioavailable minerals: Calcium, magnesium, and phosphorus in raw milk are highly absorbable, supporting strong bones, steady moods, and gut motility, the rhythmic flow of digestion.

For children moving beyond breastfeeding, raw milk offers a natural, nutrient-dense continuity, a whole food that’s alive, gentle, and perfectly in tune with a growing body’s needs. Always choose raw milk from healthy, pasture-raised animals on trusted farms, where rigorous testing ensures safety and quality.

2. Colostrum

Even more potent than raw milk is colostrum, the first milk of mammals, a concentrated source of immunoglobulins (like IgA), lactoferrin, and growth factors that train the gut’s defences and strengthen its lining. Even in small amounts later in childhood, bovine colostrum can support children with eczema, allergies, or gut imbalances, a gentle, ancestral way to guide the immune system toward balance

3. Collagen

On a misty morning, an ancient grandmother might have brewed a calming herbal broth for a child who was “acting up,” not realizing she was helping the young one’s gut as much as their mood. Collagen, found in bone broth and gelatinous cuts, provides glycine and proline to rebuild the gut’s protective lining and reduce inflammation.

For children, collagen is especially helpful after antibiotics, during growth spurts, and for skin issues like eczema. Its calming effect on the nervous system also helps ground sensitive, fussy moods. If can’t sneak bone broth in, try this Bone Broth Berry Smoothie.

4. Organs

Organ meats were revered by ancestral cultures for building strong, resilient bodies. Liver, heart, kidney, these are all encompassing multivitamins, brimming with iron, B vitamins, CoQ10, and bioavailable minerals that feed not just the gut, but also the growing brain.

Liver is especially rich in retinol (true vitamin A), iron, and choline, all critical for immune resilience and calm moods.
Heart fuels mitochondria (the energy engines in every cell) and supports focus and clarity.
Even a tiny sliver of organ meats can provide a powerful microbial and nutrient boost.

But what if my child won't eat these?

We know. Liver, colostrum, and collagen can feel like hard sells. Try getting a toddler to ask for kidney over their favourite snack.

Even with all the science and ancestral wisdom, we’re still up against fussy eaters and tiny tastebuds. That’s why we often get asked:

“Can I give Organised to my kids?”

The short answer? Absolutely. Not only can you, it’s an incredibly nourishing additions you can make to their diet. Organised is built entirely from whole foods. No synthetic vitamins, no stevia or gums, no filler ingredients. It’s gentle, bioavailable, and incredibly supportive during the years when their little bodies and brains are developing at full speed.

How to give Organised to children

For little ones, we suggest starting with one scoop instead of two. You can blend it into raw milk, kefir, or a smoothie, or for a weekend treat try these Animal Based Pancakes (a little one crowd pleaser we promise).

The taste is mild and slightly sweet (thanks to raw honey, maple, and dates), making it a stealthy and effective way to upgrade your child’s nutrition, especially for picky eaters.

Plenty of parents call it their “secret weapon”, because let’s face it, if your child won’t touch liver, this is a brilliant way to cover key nutrient gaps and support their foundation.

And if you’ve ever spoken to Niall, our founder, about his four little brothers (all under the age of 12)...

…he’ll tell you all about the legendary banana milkshake. It’s just raw milk, banana, a scoop of Organised, and a bit of raw honey. That’s it. And whenever he makes it, those boys fight over who gets the biggest glass.

For some more recipes your little ones may just fight over:

Beyond the plate

Let kids get dirty

Mud under fingernails, the scent of earth after rain, the gentle scratch of grass on bare legs, these are not just fleeting joys, but ancient practices that fortify a child’s gut and mind. The soil teems with friendly microbes, tiny teachers that train the immune system, balance inflammation, and nurture a gut garden as diverse as a forest meadow. Let children play in the garden, dig their toes into the soil and cuddle the family dog.

And avoid oversanitisation. Our quest to keep everything spotless for children, we might be depriving them of beneficial microbes. The so-called “hygiene hypothesis” and research on farm children show that kids allowed to encounter farm animals, soil, and the outdoors tend to have stronger immune systems and fewer allergies, partly because their microbiomes are richer. In one famous study, Amish children raised on traditional farms (with daily exposure to barnyard dust and raw farm milk) had astoundingly low rates of asthma and allergies compared to their modern counterpart.

Start ferments early

A teaspoon of sauerkraut brine, a sip of fizzy kefir, these ancestral ferments are microbial gifts, alive with strains that soothe inflammation and craft neurotransmitters like serotonin and GABA. When woven into a child’s diet early, these living foods can anchor a lifetime of gut harmony. Even the smallest taste of fermented veggies is a gentle invitation for friendly microbes to set up camp, building resilience from the inside out.

You can even freeze kefir or yogurt into little dots as “probiotic popsicles” for teething babies. These foods provide natural probiotics that survive stomach acid and colonise the gut. Many babies love the sour tangy taste if given the chance.

Guard sleep and sunlight

Sleep is when gut microbes do their quiet work, repairing, replenishing, and calming the immune system’s reactive fires. Sunlight, in turn, fuels the creation of vitamin D, a cornerstone of gut lining integrity and mood balance. Make space for rhythms. Early light, consistent bedtime, outdoor play, these are old tools that still hold incredible power.

Mind the gut during stress or illness

If your child does hit a rough patch, say a stomach flu, a round of antibiotics, or a stressful life event, pay extra attention to their gut.

During viral illness, focus on easy to digest broths and probiotic-rich fluids to help the gut recover. In times of stress (like moving homes or starting a new school), it can help to avoid junk food “treats” and instead use nourishing comfort foods, think warm milk with a bit of honey and cinnamon, or a homemade popsicle made from yogurt and berries, to keep their gut and mood steady.

Teach the gut garden

As they grow old enough to understand, teach your kids about their “good bugs.” You don’t have to get too technical, even a 4 year old can grasp that there are tiny helpers in their tummy that love certain foods and hate others. Many children get fascinated knowing they have an inner garden. This can lay the foundation for them to make healthy choices on their own later, because they’ll have an internalised understanding of food’s impact beyond just taste.
