Casein Protein

July 5th, 2007 by Paul Johnson

Casein is a protein source most commonly used by bodybuilders.

About Casein Protein:

Casein is often dubbed the “slow” protein powder. It is called this because in direct contrast to whey protein, it absorbs very slowly but steadily into the body. Whereas whey protein takes 45 minutes to hit peak, casein takes 3 to 4 hours to hit blood peak levels.

Which is better, Whey or Casein?

Whey protein cannot be beat for its many immune system, health, and anti-cancer properties. However due to it's fast digesting properties it is not optimal to be the main protein source in a bodybuilders diet. Casein would be better to take for most of your meals. The ideal time for whey protein is pre and post workout. Casein or whole food proteins should be taken instead at other times. Casein is much more expensive then whey protein powder, so you may want to just opt for whole food sources of protein instead.
