Health Notes

Adenosine Monophosphate

Adenosine Monophosphate
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.

Shingles and Postherpetic Neuralgia
Dose: Refer to label instructions

Adenosine monophosphate (AMP), a compound that occurs naturally in the body, has been found to be effective against shingles outbreaks. In one double-blind trial, people with an outbreak of shingles were given injections of either 100 mg of AMP or placebo three times a week for four weeks. Compared with the placebo, AMP promoted faster healing and reduced the duration of pain of the shingles.1 In addition, AMP appeared to prevent the development of postherpetic neuralgia.2, 3

Adenosine monophosphate (AMP) is a substance made in the body that is also distributed as a supplement, although it is not widely available. According to one report, 90% of people with porphyria cutanea tarda responded well to 160 to 200 mg of AMP per day taken for at least one month.1 Complete alleviation of photosensitivity occurred in about half of the people who took AMP.
