Goat’s Milk Formula and Immune Support
Gastro. Hand, foot and mouth. Conjunctivitis. Ear infection. RSV. The 3am “Mum, I don’t feel good.”
You’re not imagining it — kids get sick a LOT. The Royal Children’s Hospital Melbourne reports that it’s normal for a “healthy” child to have up to 12 viral illnesses per year.
Per. Year.
If you’re using goat’s milk formula and wondering what it contains that’s relevant to your child’s immune health — this is the honest, science-backed answer. Not a miracle, not a cure. Just the actual nutrients, how they work, and what the research shows.
Will Goat’s Milk Formula Stop My Kid Getting Sick?
No. And honestly — we’d be suspicious of anyone who told you it would.
Sickness in young children isn’t just unavoidable. It’s actually part of normal immune development. Even breastfed babies who receive an added layer of protection from the antibodies in breast milk still get sick. Illness helps the immune system build its own antibody response over time.
What formula can do is ensure your child is getting the right nutrients to support normal immune function — so their body has what it needs to respond well.
Here’s what’s in Oli6 that relates to that.
Vitamins That Support Normal Immune Function
Oli6 Goat Milk Formula contains zinc and vitamin C — both of which are listed under FSANZ Schedule 4 as nutrients with approved relationships to normal immune function.
Zinc
Zinc contributes to the normal function of the immune system. It also supports wound healing, normal growth, and the metabolism of several key nutrients. One serve of Oli6 Toddler Drink contains 1.5mg of zinc.
Healthdirect Australia notes that zinc is an essential mineral for fighting off infection — a useful reference for parents who want to understand why it’s included.
Vitamin C
Vitamin C contributes to the normal function of the immune system, and supports the formation of red blood cells, bones, and tissue repair. One serving of Oli6 Toddler Drink provides nearly half (47%) of the recommended daily intake of Vitamin C for toddlers.
Goat milk naturally contains 37% more vitamin C than cow milk — so even before Oli6’s formulation adds more, the base ingredient has a head start.
Vitamin A
Vitamin A plays a role in normal immune function, as well as vision, skin health, and cell production. Goat milk naturally contains 46% more Vitamin A than cow milk.
Magnesium
Goat milk naturally contains 33% more magnesium than cow milk — a mineral that contributes to normal muscle function, energy metabolism, and protein synthesis. Magnesium is included in Oli6 as part of its overall nutritional profile.
The Gut–Immune Connection
There’s well-established research on the relationship between gut microbiome health and immune development in children. A healthy, balanced gut environment is associated with healthy immune function — which is part of why the prebiotic and probiotic profile of goat milk formula matters.
Prebiotics: 14 Natural Oligosaccharides
Our RMIT University study, peer-reviewed and published in the *British Journal of Nutrition* (Xiao et al., 2019), confirmed that Oli6 contains 14 naturally occurring prebiotic oligosaccharides — five of which are also found in breast milk.
In laboratory conditions, these oligosaccharides were shown to selectively promote the growth of beneficial Bifidobacteria while limiting the growth of harmful bacteria. That selective action is what “prebiotic” means: fuel for the good bacteria, not the bad ones.
Oli6 also adds genuine human milk oligosaccharides (HMOs) — bringing the prebiotic profile closer still to breast milk.
BB536 Probiotic
Bifidobacterium longum BB536 is one of the most extensively researched probiotic strains used in infant formula. It forms part of our SynbiOli™ synbiotic blend — where the naturally occurring prebiotics in goat milk provide the fuel, and the BB536 probiotic provides the beneficial bacteria.
Research suggests BB536 may support a healthy gut microbiome. Combined with zinc and vitamin C — and the gut–immune relationship that’s well-documented in the research literature — this is why the SynbiOli™ blend as a whole may support healthy immune function.
We say “may support” because that’s accurate. Infant nutrition is complex, every baby is different, and we won’t overstate what the evidence shows.
Goat’s Milk Formula vs Breast Milk for Immune Support
Breast milk is genuinely exceptional for immune support. It contains antibodies — specifically secretory IgA — that transfer immune protection from parent to baby in a way no formula can replicate.
While goat’s milk formula (or any formula) can’t provide antibodies, it does contain nutrients that support healthy immune development in its own right: zinc, vitamin C, vitamin A, naturally occurring oligosaccharides, and added HMOs.
For families who are formula feeding or combining breast and bottle, Oli6 is formulated to be as nutritionally complete as possible — including the nutrients relevant to normal immune function.
What Most Parents Actually Want to Know
Does the formula help at all?
Yes — not by preventing illness, but by ensuring your child has the nutrients their body needs to support normal immune function. That’s the honest, evidence-based answer.
Is zinc the key ingredient?
Zinc and vitamin C are the two nutrients with pre-approved relationships to immune function under Australian food standards. Oli6 contains both.
Is the probiotic important?
BB536’s role is gut microbiome support — and a healthy gut microbiome is associated with healthy immune development. It’s not a magic bullet; it’s one well-researched component of a complete nutritional system.
Should I give vitamin supplements too?
That’s a question for your GP or paediatrician. Medical professionals generally recommend a varied diet over-reliance on supplements — and most children get the nutrients they need from what they eat and drink, including their formula.
Frequently Asked Questions
Does goat milk formula help with immunity?
Goat milk formula contains zinc and vitamin C, which contribute to the normal function of the immune system under Australian food standards. It also contains BB536 probiotic and 14 natural prebiotic oligosaccharides that support a healthy gut microbiome — and the gut–immune relationship is well-documented in research. It supports normal immune function; it doesn’t prevent illness.
What vitamins are in Oli6 for immune support?
Oli6 contains zinc, vitamin C, and vitamin A — all relevant to normal immune function. One serve of Oli6 Toddler Drink provides nearly half the recommended daily intake of vitamin C for toddlers, and 1.5mg of zinc.
Does BB536 probiotic support immunity?
BB536 is a probiotic that may support a healthy gut microbiome. A healthy gut microbiome is associated with healthy immune development. Oli6’s immune function story runs through this gut–immune connection, supported by zinc and vitamin C.
Is goat milk naturally higher in immune-supporting nutrients than cow milk?*
Goat milk naturally contains 37% more vitamin C, 46% more vitamin A, and 33% more magnesium than cow milk per 100ml. These are compositional differences, not claims that the formula treats or prevents illness.
Will Oli6 stop my toddler from getting sick at daycare?
No formula will. Daycare illness is genuinely normal — and part of how young immune systems develop. With the right nutrition in place, your child’s body has what it needs to respond well.
