Health Notes

Lysine

Lysine
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Cold Sores
Dose: 1 to 3 grams daily
Supplementing with lysine may reduce recurrences by suppressing the virus that causes sores.(more)
Cold Sores
Dose: 1 to 3 grams daily
Supplementing with lysine may reduce recurrences by suppressing the virus that causes sores.(more)
Shingles and Postherpetic Neuralgia
Dose: Refer to label instructions
Because shingles is caused by a herpes virus, some doctors believe that lysine could help, since it inhibits replication of herpes simplex, a related virus.(more)
Cold Sores
Dose: 1 to 3 grams daily

The amino acidlysine has been reported to reduce the recurrence rate of herpes simplex infections in both preliminary1, 2 and double-blind trials.3, 4 The amount used in these studies was usually 1 to 3 grams per day, although some people received as little as 312 mg per day. In one double-blind trial, lysine supplementation (1,200 mg per day) failed to prevent recurrences better than placebo.5 However, the results of that study may have been skewed by a large number of dropouts in the placebo group who fared poorly but were not included in the analysis.

When lysine has been used for acute outbreaks, the results have been mixed. In a preliminary study, 390 mg of lysine taken at the first sign of a herpes outbreak resulted in rapid resolution of the cold sores in all cases.6 However, in a double-blind study, supplementing with 1 gram of lysine per day for five days did not increase the healing rate of the cold sores.7

Shingles and Postherpetic Neuralgia
Dose: Refer to label instructions

Because shingles is caused by a herpes virus, some doctors believe that lysine supplementation could help people with the condition, since lysine inhibits replication of herpes simplex, a related virus. However, lysine has not been shown to inhibit Varicella zoster, nor has it been shown to provide any benefit for people with shingles outbreaks. Therefore, its use in this condition remains speculative.

Lysine is an essential amino acid needed for growth and to help maintain nitrogen balance in the body. (Essential amino acids cannot be made in the body and must be supplied by the diet or supplements.)
