Does Lysine work for cold sores?
What is Lysine?
Lysine is essential for many bodily functions, including helping with calcium absorption and collagen formation. Most people will consume enough lysine in their diet for their body’s basic needs. L-lysine, or simply lysine, is an essential amino acid involved in making proteins and metabolizing carbohydrates and fatty acids. In the laboratory, it hampers the activity of arginine, an amino acid that promotes the growth of HSV. This suggested that increasing lysine intake might work against HSV infections. But results of studies in humans have been inconclusive and a recent Cochrane review of cold sore prevention failed to find any evidence that lysine is effective. (Harvard’s Women’s Health, March 2007). In addition, many supplements like Lysine are unregulated by the FDA and may contain unlisted ingredients or fillers that may potentially cause adverse effects.
tetraVIV, a better alternative to Lysine
tetraVIV Advanced Cold Sore Care is a new era in a patented formulation. tetraVIV has emerged to provide users with relief and resolve along any stage of the cold sore. As recognized by the FDA (Federal Monograph,2003), tetraVIV patented tetracaine based formulation is a suitable active to address cold sores. This is further supported by a publication in Archives of Virology (March 1998, Volume 108,Issue 1-2; pp 151-159) entitled Destabilization of Herpes SimplexVirus Type 1 Virions by Local Anesthetics, Alkaline pH, andCalcium Depletion by Yanagi, et. al.
The above study suggests that the tetracaine in tetraVIV is able to destabilize the cold sore. This unique patented formulation is also an alkaline base to further destabilize the virus that causes cold sores. Having such a lipophilic environment in the base, along with alipophilic solvent, lowers the surface tension to allow the active to flux through the membrane (Miller, et al, 1993). Along any stage of the cold sore, this formulation attacks the viral integrity. It also addressing the itching, burning, and painful experiences of cold sores reported by the sufferers; tetracaine is known to be a long-acting anesthetic.
Sources of Lysine
Lysine is an essential amino acid. The human body does not naturally produce lysine, so we need to get it from our diet or take a supplement. Foods containing lysine include: pork, turkey, chicken, beef, eggs, yogurt, Parmesan cheese, soybeans, sardines, and codfish.
Risks of Lysine
Most doctors agree that lysine is safe to use either as a cream or oral supplement. It is important to follow the instructions on the packaging when using lysine products. Too much lysine can cause side effects, including: nausea, diarrhea, gallstones, cramps, abdominal pain and kidney issues. Pregnant and breastfeeding women should not take lysine supplements unless their doctor recommends it.
