''Bodybuilding Supplements''

Bodybuilders often take a powdered form of protein, the essential building blocks for muscle. Protein powder is generally consumed immediately before and after exercising, or in place of a meal.[citation needed] The theory behind this supplementation is that having a sufficient protein intake allows for efficient growth and repair of muscle tissue.



Whey protein is the most commonly used type of protein.[citation needed] It is absorbed by the body very quickly and easily. It contains high levels of all the essential amino acids, branched-chain amino acids and has the highest content of the amino acid cysteine which is important for the biosynthesis of glutathione; which has extremely important immune boosting properties for the body.[citation needed]
Casein protein (or Milk protein) is the richest in glutamine, an amino acid that aids in recovery[citation needed], and has casomorphin which helps the body to absorb the amino acids over a long time.
Soy protein contains all essential amino acids, and is an alternative protein for vegans. Soybeans also contain isoflavones, a type of phytoestrogen, which have a weak estrogenic activity.[1][2]
Egg white protein is a lactose- and dairy-free protein.
Hemp seed contains complete and highly-digestible protein and hemp oil is high in essential fatty acids.
