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 schizophrenia
| 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 |
|
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.

D-Serine supplementation is able to reduce symptoms of schizophrenia (more efficacy on negative and cognitive symptoms rather than positive) in a dose-dependent manner between 30-120mg/kg, but possibly due to the unreliable increases in blood D-serine its benefits are also unreliable

At the dose that showed anti-depressant effects, inositol failed to improve any symptoms associated with schizophrenia.
