Protein powders can come from different sources, including:

Whey protein is one of the most popular protein supplements in the sports nutrition market.
It is derived from milk and is widely recognized for its high-quality protein profile.
One of the main advantages of whey protein is its excellent amino acid composition, including essential amino acids that support muscle nutrition.

Another advantage is convenience.
It can be easily mixed with:
