Whey protein is a by-product in the cheese making process. It is made from the watery portion of the milk. Even though it is a by-product, it is highly nutritious.

#2. Not for lactose intolerant

Since it is a dairy product, it is not recommended for people with milk allergies or who are lactose intolerant. Also, different supplements have different calories and lactose content.
