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. 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. It contains high levels of all the essential amino acids and is absorbed by the body very quickly.
* Casein protein (or Milk protein) is the richest in glutamine, an amino acid that aids in recovery, 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 vegetarians. Soybeans also contain isoflavones, a type of phytoestrogen, which have a weak estrogenic activity.
* 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.
