Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect kidney function
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.
Notes
grade-a Creatine - Very High See all 13 studies
In otherwise healthy persons given creatine supplementation, there is no significant beneficial nor negative influence on kidney function.
grade-c Curcumin Minor Very High See 2 studies
Appears to promote kidney function in instances where function is normally hindered
grade-c Astaxanthin - - See study
grade-c Benfotiamine  
grade-c Chromium  
grade-c Cordyceps  
grade-c Lactobacillus reuteri  
grade-c Trimethylglycine
