L-Lysine 500mg Vegetarian Capsules

Derived from natural sources, Natural Factors' lysine amino acid supplement provides nutritional support for depressed immune systems. Known for its antiviral properties, lysine is often used to fight cold sores and other viral infections. Your body is unable to manufacture this essential amino acid on its own so it must be ingested from either foods or supplements.

  •  An essential amino acid.
  •  Supports immune system health.
  •  Helps to reduce the severity and healing time of cold sores.
  •  May also be helpful for shingles, herpes and other viral infections.
  • Vegetarian capsule.

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.
