Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect c-reactive protein
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 Fish Oil - Very High See all 16 studies
Although some decreases have been noted, the vast majority of the evidence suggests that there is no significant influence
grade-b Curcumin Minor High See all 3 studies
May decrease C-reactive protein if elevated
grade-b Hesperidin Minor High See all 3 studies
There is a decrease in C-Reactive Protein (inflammatory biomarker) in those with higher baseline inflammation or inflammatory disease conditions, but not in healthy persons.
