Is there lactose in goat milk?
High — and not lactose-free.
Despite the common myth, goat milk is not lactose-free. It contains almost as much lactose as cow's milk, so it's still a trigger — though some people find its protein easier to digest.
Here’s a myth worth busting: goat milk is not lactose-free. It’s one of the most common mix-ups we hear, probably because some people genuinely find goat’s dairy easier on the stomach. But that’s usually down to its different proteins and fat, not the lactose — which is nearly as high as in cow’s milk.
If this is you: if you switched to goat milk hoping to dodge lactose and it still upset you, this is why. If it does sit better for you, that’s more likely a protein thing — worth knowing, but it’s not a lactose-free pass.
How much lactose is in goat milk?
Goat milk contains about 4.1–4.5 g of lactose per 100 mL — roughly 10–11 g in a 250 mL glass, only a touch under cow’s milk. A full glass is a real lactose load.
| Food | Lactose per 100 mL | Per typical serve |
|---|---|---|
| Goat milk | 4.1–4.5 g | ~10–11 g (250 mL) |
| Cow's milk | 4.8 g | ~12 g (250 mL) |
| Lactose-free milk | <0.1 g | ~0.1 g (250 mL) |

When you can still enjoy it
If it’s the goat flavour you love, a small splash may suit — but for a proper drink, lactose-free dairy milk or a plant milk is the safe bet. Aged goat cheeses (like a hard goat’s cheddar) are far lower in lactose than the milk.
