Lysine is an essential amino acid that your body doesn’t produce on its own, which means it must come from diet or supplementation. Primary dietary sources of lysine are meat, poultry, fish and dairy. However, because many individuals don’t get enough lysine through diet alone, supplementation of this essential amino acid is advisable.

Thorne’s Lysine uses the purest, most absorbable form of this amino acid – without adding unnecessary additives or preservatives. Health benefits of lysine include:

  • Wound healing – Lysine is often recommended for supporting the healing of sores and wounds because of its benefits to collagen formation and immune function.
  • Some evidence indicates lysine can be beneficial for maintaining healthy gum and lip tissues.
  • Promotes immune health – lysine provides nutritional support to help your body maintain its natural defences.
  • Skin health – This amino acid is known to promote collagen formation, which in turn benefits the health and elasticity of skin.
  • Bone Health – lysine promotes calcium absorption, which is needed to maintain strong bones and teeth.

Vegetarians or vegans eating a lot of grains run the risk of being deficient in lysine. 

Lysine is known for its use in treating herpes simplex virus (HSV). Lysine hinders the herpes virus from reproducing. Herpes virus uses arginine in its reproduction and lysine stops that mechanism. The dose is important if you take lysine to treat herpes. 3000 mg is a recommended dose for adults against herpes while doses of 1250 mg did not work as well according to research. 

Contact If you suffer from herpes, we recommend L-Lysine in combination with Ultra C and Vitamin D3. Vitamin C contributes to a normal immune system and to normal collagen formation, which is important for the normal function of the skin. Research has established a significant association between low serum vitamin D levels and the presence of Herpes.
