Scientific Information on Symptoms of OCD

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect symptoms of ocd
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 mo re 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-c Inositol Minor - See study
Although a small decrease, there appear to be benefits to OCD symptoms associated with high dose inositol supplementation
grade-c Valeriana officinalis Minor - See study
The lone study assessing the effects of valerian and OCD found a benefit with treatment relative to placebo.
grade-c Zinc Minor - See study
High dose zinc (220mg twice daily) may have a minor additive role to standard OCD therapy (fluoxetine), although the small magnitude of benefit and the high dose used suggest that it is not the best supplemental option.
grade-c N-Acetylcysteine - - See study

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

The evidence for each separate supplement is still freely available ​here.
