Provides 500mg of the essential amino acid L-lysine. Amino acids are used by the body to form proteins, which are required for biological functions and cell structures. L-lysine supports immune function and has been shown to inhibit the herpes simplex virus responsible for cold sores. It may increase the absorption of calcium and recommended as a supplement for those eating a vegetarian or vegan diet as it is not found in many non animal foods. Lysine is an essential amino acid which cannot be manufactured in the body and must be obtained from diet or by way of supplements.

- May increase the absorption and retention of calcium, the major structural component of bone
- A higher ratio of lysine to another amino acid, arginine, in the body impacts immune function.
- Collagen, the major protein in the skin, is rich in lysine

The use of L-Lysine in the treatment of cold sores is well documented. The herpes virus, one of the underlying causes of cold sores, can be sparked off by a number of factors including over-consumption of certain types of foods (e.g. alcohol, chocolate, peanuts) rich in the amino acid L-Argine. When there is too much L-Arginine, L-Lysine is reduced in the body and when this imbalance occurs the herpes virus can be activated. So by taking L-Lysine and restoring the body's balance of these two amino acids, the virus can be overcome sooner. Excess exposure to sunshine can also weaken the immune system and bring on the herpes virus, as can stress, a major offender all year round. The topical use of A Vogel's Bio-Propolis together with L-Lysine will dramatically speed up the recovery period. It is not just a soothing ointment which will act as an effective barrier to protect the lips but it has amino acids, vitamins and minerals which will combine as an antifungal barrier to support lip health as they recover.
