Lactose is the name of a specific carbohydrate or sugar of milk. Unlike proteins and fats, lactose in all milks is chemically and biologically identical. Goat milk contains lactose just like cow milk. There is no difference so it is unlikely that the lactose in goat milk will help directly with lactose intolerance.

However, other factors may play a role in this. For example goat milk contains oligosaccharides similar in structure to human milk oligosaccharides.¹ Oligosaccharide concentrations in goat milk from New Zealand are approximately 10 times higher than cow milk.² These oligosaccharides may influence how lactose is metabolised.
