Natural Factors L-Lysine 500 mg Free Form Amino Acid - Cold Sore Relief


One of the most natural nutritional aids for the herpes simplex virus (HSV) is the amino acid L-Lysine. It provides cold sore relief by helping to reduce their recurrence, severity, and healing time. L-Lysine is one of nine essential amino acids that the body needs for repairing tissue, forming collagen, and producing hormones. It is considered essential‚ because the body cannot manufacture it and it must be obtained through the diet.

People who have problems with HSV may need supplemental L-lysine to keep the virus in check. Natural Factors L-Lysine is a free-form amino acid which is more effective than when obtained directly from food. Each 500 mg is delivered in a vegetarian capsule to benefit vegetarians, vegans, or people following restricted diets who may not get enough L-lysine through food sources alone.

L-lysine should be an essential part of everyone 's nutritional plan to prevent flare-ups of HSV, in whatever form it may take. For the most effective control of HSV, combine L-lysine supplementation with a low-arginine diet. Taking it with vitamin C and zinc may also provide additional benefits by supporting immune system health.
