The Protein Question

Any protein, whether it be whey, casein, or soy is made up of amino acids, which are the building blocks of muscle.  However, that’s where the similarities end. Here’s a brief description of the differences between the 3 main types of protein:

Whey - This protein absorbs the fastest and contains the most concentration of amino acids. Consumption is ideal immediately after a workout or activity to replenish the muscles.

Casein - This protein derives from milk and has the highest amount of glutamine (the most abundant amino acid found in your muscles).

Soy - A product of soybeans, it is considered the “complete protein” because it provides all of the essential amino acids and isoflavones (which may help reduce cholesterol).

Ideally, an athlete or someone looking to increase muscle mass should get an equal amount of protein from each source and strive for at least 1.5 grams of protein per pound of body weight each day.
