Additional Information

Lysine was first identified when it was isolated from casein protein in 1889. It has been classified as an essential amino acid as the body is not able to synthesize it at all. It assists in various physiological processes and has a beneficial synergistic effect against viruses when combined with Vitamin C. Lysine supplements are commonly used as effective treatment against oral and genital herpes as well as shingles.

Bodily Functions Lysine Assists

One of lysine’s most important roles within the body is in the production of carnitine. It is needed to create carnitine which allows the body to convert fatty acids into usable energy. Lysine is also critical in the battle against viruses. Along with vitamin C, A, and zinc, it helps prevent the proliferation of virus cells and ultimately helps eliminate the presence of viruses. Other physiological processes that lysine is involved include the synthesis of collagen, enhanced absorption of calcium, general development and growth, as well as maintaining an adequate level of blood cholesterol.

Symptoms Of Deficiency:
  • Fatigue
  • Nausea
  • Loss of appetite
  • Irritability
  • Red eyes
  • Stunted growth

Ailments That Lysine Helps Against:
