Goat Milk Formula vs Cow Milk Formula: Which Is Right for Your Baby?
Walk into any pharmacy or baby store in the UK and you'll find formula made from cow's milk — it's by far the most common type. But goat milk formula has grown enormously in popularity over the last decade, and more parents than ever are asking whether it could be a better fit for their baby. This guide covers everything you need to know to make an informed choice.

What Is Cow Milk Formula?
The vast majority of baby formula sold in the UK is based on cow's milk. The milk is processed and modified to make it safe and appropriate for babies — cow's milk in its natural form is not suitable for infants under 12 months as a drink. Manufacturers adjust the protein ratio, add vitamins and minerals, and remove excess salt to create a nutritionally complete infant food.
Cow milk formula is the most extensively researched type of formula in the world, and all major UK brands — including Aptamil and Kendamil Classic — are based on it. It is safe, nutritious, and appropriate for the vast majority of babies.
Top cow milk formulas we stock:
- Aptamil Stage 1, 2 & 3 — one of the UK's most trusted brands
- Kendamil Classic & Organic (Stage 1, 2 & 3) — whole milk, palm oil free, made in the UK
What Is Goat Milk Formula?
Goat milk formula uses goat's milk as its base instead of cow's milk. Like cow milk formula, it is heavily processed and nutritionally fortified to meet the strict UK and EU infant formula regulations. Goat milk formula is not the same as giving your baby goat's milk — raw or pasteurised goat's milk is not suitable for babies under 12 months.
Goat milk formula has been approved for use in the UK and EU since 2014, and is produced by brands including Kendamil (Goat) and Nannycare.
Top goat milk formulas we stock:
- Kendamil Goat (Stage 1, 2 & 3) — whole goat milk, no maltodextrin, UK-sourced
- Nannycare (Stage 1, 2 & 3) — 30+ years of heritage, NZ goat milk
The Key Differences Between Goat and Cow Milk Formula
1. Protein Structure
This is the most meaningful difference. Cow's milk is high in a protein called alpha-S1 casein, which forms a relatively firm curd in the stomach. Goat milk naturally contains much less alpha-S1 casein, and its proteins form a softer, more loosely structured curd. Many parents find their babies digest goat milk formula more comfortably as a result.
2. Fat Composition
Goat milk has a slightly different fatty acid profile to cow's milk, with more medium-chain fatty acids, which are absorbed relatively quickly. Kendamil Goat preserves this by using whole goat milk, while some other goat formulas use skimmed goat milk and add vegetable oils.
3. Lactose
Both goat and cow milk formula are lactose-based. This is important to understand: goat milk formula is not a lactose-free product. If your baby has been diagnosed with lactose intolerance (rare in infants), neither type is appropriate — you'll need a specialist formula.
4. Taste
Goat milk formula has a slightly more distinctive taste compared to cow milk formula. Most babies adapt without difficulty, especially if introduced gradually.
5. Allergen Profile
This is critical: goat milk formula is not suitable for babies with diagnosed Cow's Milk Protein Allergy (CMPA). The proteins in goat milk are similar enough to cow's milk proteins that cross-reactivity is possible. If your baby has CMPA, your GP will prescribe an extensively hydrolysed or amino acid-based formula.
Who Should Consider Goat Milk Formula?
Goat milk formula is worth considering if:
- Your baby seems unsettled, gassy, or uncomfortable on cow milk formula, and your GP has ruled out CMPA
- You want to try a formula with a different protein structure before seeking a prescription formula
- You have a family history of mild dairy sensitivity (though always discuss with your health visitor first)
- You prefer a formula that is closer to the natural composition of the source milk (especially Kendamil Goat with its whole milk base)
Always speak to your GP or health visitor before switching formula, especially if you suspect your baby has an allergy or intolerance.

Frequently Asked Questions
Is goat milk formula better than cow milk formula?
Not universally. Both are safe and nutritionally complete. Goat milk formula's different protein structure may suit babies who seem unsettled on cow milk formula, but for most babies cow milk formula works perfectly well.
Can I switch from cow milk to goat milk formula?
Yes, but do so gradually over 5–7 days, mixing increasing proportions of the new formula with the old. Consult your health visitor before switching.
Is goat milk formula suitable from birth?
Yes. Both Kendamil Goat Stage 1 and Nannycare Stage 1 are suitable from birth as a sole source of nutrition.
Is goat milk formula lactose free?
No. Goat milk formula contains lactose. It is not suitable for babies with lactose intolerance.
Does goat milk formula help with wind and colic?
Some parents report improvement in gassiness and unsettledness after switching to goat milk formula. This is thought to be related to the softer curd formation. However, there is no clinical evidence that it treats colic. Always speak to your health visitor or GP if your baby seems distressed.
