Scientific Information on Asymmetric dimethylarginine (aka ADMA)

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect asymmetric dimethylarginine (aka adma)
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
grade-b Arginine - Very High See all 3 studies
Although there is some evidence for an increase in ADMA (a negative regulator of NOS that is derived from L-arginine), it does not appear to occur most of the time
grade-d Vitamin C - - See study

All comparative evidence is now gathered in our ​A-to-Z Supplement Reference.
