A2 Goat Milk Formula Explained
One of the main reasons that goat’s milk formula is easier to digest is that it’s naturally A2. And we’re not talking giant pieces of paper.
Read on to learn what ‘A2’ means when it comes to formula, and what makes A2 infant formula worth understanding for families exploring their options.
What does A2 mean?
It’s all to do with proteins.
Milk contains two major proteins: casein and whey. When you break it down further, there are four subtypes of casein. Two of these are classified as beta-caseins: A1 beta-casein and A2 beta-casein.
Most cow’s milk contains both A1 beta-casein and A2 beta-casein. However, some cows only produce A2. Goat’s milk always contains very little to no A1 beta-casein proteins.
So when it comes to infant formula, A2 blends will typically be made from specifically bred cows that don’t produce A1 proteins. And while ‘A2’ may not feature in the product or brand name, goat’s milk formulas are naturally A2 as well.
Is A2 infant formula better for formula feeding newborns?
What’s interesting is that human breast milk is very low in A1 beta-casein. A2 milks, including goat’s milk, are closer in composition to human milk, and some research suggests they may be easier on the digestive system.
When it comes to newborns, A2 formula may help support digestive comfort for formula-fed babies — making it worth considering for families whose babies seem unsettled on standard cow’s milk formula. And while goat’s milk formula naturally offers the potential benefits of A2 protein, it has so much more to offer developing infants too.
What does the research say about A1 beta-casein?
Some research suggests that the A1beta-casein may be harder to digest for some people, and that this could contribute to digestive discomfort.
However, a lot of this research is based on animal studies and is not considered conclusive when it comes to human health effects. It’s important to note that the vast majority of infant formulas on Australian shelves are derived from cow’s milk and are safe and nutritionally complete for all babies.
A2 infant formula and digestive comfort
Newborns have a lot going on inside. While all they seem to do is eat and poop, it’s astounding how much effort can be involved in eating and pooping!
For parents, there’s the process of choosing the right formula, preparing formula for feeds, and changing a heck of a lot of nappies. There’s also the added effort of dealing with babies’ digestive discomfort as their bodies grow, develop, and adjust to life outside the womb.
Here are a few ways the naturally A2 protein structure in goat’s milk formula may support digestive comfort for formula-fed babies. As always, consult your healthcare professional for advice specific to your baby.
A2 goat’s milk formula for colic
Colic is a bit of an anomaly, and it’s not always obvious what causes the hours of inconsolable crying. Sometimes it’s related to intolerance, but it could just as easily be a matter of pain and discomfort caused by a baby’s tiny body adjusting to life outside the womb. For some babies, a gentler A2 formula may help ease digestive discomfort associated with feeding. Speak to your paediatrician about whether switching formulas is appropriate.
A2 goat’s milk formula for constipation
Constipation in infants is common and frustrating. Naturally A2, goat’s milk formula may suit some babies better — its smaller, gentler protein molecules form softer curds that may be easier for little ones to process. Talk to your doctor if your baby is experiencing ongoing constipation.
Goat’s milk formula and cow’s milk protein sensitivity
Infants with cow’s milk protein intolerance (CMPI) sometimes react to proteins in standard cow’s milk formula. Goat’s milk formula may be a gentler alternative for some of these babies, but importantly, goat’s milk is **not suitable for babies with confirmed cow’s milk protein allergy (CMPA)** — as cross-reactivity is possible. Always consult your healthcare professional before switching formula for a baby with diagnosed allergies or intolerances.
Goat’s milk formula and reflux
There can be a range of reasons that some babies experience infant reflux. Some parents find that Oli6 Goat Milk Formula suits their baby’s tummy better than other formulas they’ve tried, and the naturally A2 protein structure may be part of why some babies tolerate it better. As always, speak to your doctor if reflux symptoms are persistent or severe.
Goat’s milk formula for babies with general sensitivities
In some babies, the issue can’t be boiled down to one thing. They may be generally fussy after feeds, or show a combination of symptoms at different times. A2 infant formula may be worth exploring for babies with general feeding sensitivities — always in consultation with your health professional.

A2 refers to A2 beta-casein, a type of protein found in milk. Most cow’s milk contains a mix of A1 and A2 beta-casein proteins. Goat’s milk is naturally very low in A1 beta-casein, making it naturally A2. Some research suggests A2 milk proteins may be easier to digest for some babies.
