L-Lysine Powder 100g

Lysine is an amino acid found in the protein of foods such as beans, cheese, yogurt, meat, milk, brewer's yeast, wheat germ, and other animal proteins. Proteins derived from grains such as wheat and corn tend to be low in lysine content.

The bioavailability of lysine is reduced with food preparation methods, such as heating foods in the presence of a reducing sugar (ie, fructose or glucose); heating foods in the presence of sucrose or yeast; and cooking in the absence of moisture at high temperatures. The average 70 kg human requires 800 to 3,000 mg of lysine daily.

Suggested uses

Lysine has been studied for the prevention and treatment of:

  • herpes infections / cold sores (caused by the virus herpes simplex labialis).

How it works:

It seems to prevent the herpes virus from growing. It also increases the intestinal absorption of calcium and eliminates its excretion by the kidney, suggesting that it might be helpful in osteoporosis.


Lysine may be dosed from 1 to 3 g daily to prevent or treat herpes simplex infections, reserving the higher dosages for breakouts It is taken by mouth and can also be applied directly to the skin if there is a cold sore breakout. In addition to the amount found in the average American diet, L-Lysine given at doses in this range appears to be safe for use in adults and pre-pubertal children.
