Symptoms of OCD Research Analysis

Summary of Symptoms of OCD

Scientific Information on Symptoms of OCD

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 [show legend]
	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

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
Inositol	Minor	- See study	Although a small decrease, there appear to be benefits to OCD symptoms associated with high dose inositol supplementation
Valeriana officinalis	Minor	- See study	The lone study assessing the effects of valerian and OCD found a benefit with treatment relative to placebo.
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.
N-Acetylcysteine	-	- See study

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