Is it vegan? Ingredients
Is lactose vegan?
Quick answer: No. Lactose is the natural sugar in milk, so it is a dairy ingredient and not vegan.
Also called: milk sugar, lactose monohydrate, lactitol (E966)
Why it isn’t vegan
Lactose is the main carbohydrate in mammalian milk. It is used as a filler in tablets and capsules, in baked goods and sweets, and as a carrier for flavourings. Lactitol (E966), a sweetener, is made from lactose.
“Lactose-free” products are usually still dairy products with the lactose broken down, so they are not vegan. In medicines, lactose is a common excipient; ask a pharmacist about lactose-free alternatives if this matters to you.
