Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect immunoglobulin g
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 - High See all 4 studies
IgG has been noted to be increased once when colostrum was used as a vaccine adjuvant (relative to skim milk with whey as control), but in general there is no influence without coadministered vaccination.
grade-c Minor - See study
An increase in IgG concentrations has been noted to occur with saffron supplementation alongside a decrease in IgM and no influence on IgA.
grade-c Minor Moderate See 2 studies
IgG has been noted to be increased when vitamin E is used as a vaccination adjuvant, but not in otherwise healthy persons not subject to a vaccination.
