FAQ
Is lactose-free milk vegan?
No. Lactose-free milk is still cow's milk; it simply has the enzyme lactase added to it to break down the lactose for easier digestion.
Why is lactose in pills?
Lactose is highly stable, compresses easily, and is very cheap, making it a popular inactive ingredient (excipient) in pharmaceutical tablets.
