Short answer Whey is a complete, quickly digested protein from milk. A typical serving provides 20g to 25g of protein. Protein contributes to the growth and maintenance of muscle mass.

Concentrate, isolate, hydrolysate

Concentrate is the standard; isolate is filtered for less lactose and fat; hydrolysate is pre-digested and dearer. For most people concentrate is fine.

How much

Total daily protein matters more than timing. For a lighter option, Oriflame's Natural Balance Shake gives 7.3 to 7.7g per serving from whey, egg and pea.
