Whey protein is a part of milk protein which is thought to be healthier than other forms of protein that people consume. Whey is one of the two proteins found in milk that people often use as a supplement. This form of protein can be readily absorbed by the body faster than other varieties of protein. Additionally, whey provides a substantial amount of L-cysteine, an amino acid which helps combat deficiencies that naturally occur with age and in those with diabetes. Many people believe that whey protein helps promote fat loss, but this effect is due to protein itself as opposed to whey specifically. Individuals with kidney or liver issues should avoid whey consumption as it can be harmful for those with existing conditions. Orally, whey protein is used to improve:

  • Athletic performance
  • An alternative to milk for people with lactose intolerance
  • Protein allergy
  • Treatment of asthma
  • Hyperlipidemia
  • Promote weight loss
  • Replacing or supplementing milk-based infant formulas
  • Atopic disease in infants
  • Treating metastatic carcinoma
  • Colon cancer
  • Reversing weight loss
  • Increasing glutathione (GSH) in people with HIV disease
