What Is L-Lysine?

Lysine, a building block for protein, is an essential amino acid, which means it is not produced by our bodies. Therefore, it has to be obtained through our diet. Lysine helps encourage a healthy stress response and helps inhibit glycation, which can play a role in a variety of age-related factors.

Among its potential health benefits, lysine supplementation has been shown to increase calcium absorption and retention.

L-Lysine Benefits

  • Supports healthy nitrogen balance
  • Promotes healthy calcium metabolism
  • Encourages a healthy stress response
  • Helps inhibit glycation

Fight Against Age-Related Factors

Lysine is an essential amino acid necessary for growth, and it helps maintain nitrogen balance in the body. It also appears to inhibit glycation, a biochemical reaction that can contribute to a variety of age-related factors. Glycation events disrupt the normal function of protein and lipid structures in the body and are accelerated by elevated levels of sugar in the blood.
