Is Casein Protein Powder bad for you?

No, casein protein powder can be an excellent source of increased protein intake when used correctly. Casein protein powder unlike other protein sources is unique in that it provides a constant slow release of essential amino acids over a long period of up to 7 hours.

The use of casein protein powder has only been found to cause problems for those that have a pre-existing health condition or lactose intolerance. Casein protein powder is usually reasonably high in lactose and those with digestive issues as a result of lactose intolerance should consider an alternative protein source such as egg protein powder.
