| 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 |

The amount of high quality evidence. The mo
re evidence, the more we can trust the results.

each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.

Notes |
|---|---|---|---|---|
|
|
Polypodium leucotomos |
Notable
|
- See study |
Limited evidence suggests potent anti-psoriatic effects.
|
|
|
Zinc |
Notable
|
- See study |
Topical application of a 0.25% zinc pyrithione cream is associated with highly significant reductions in psoriasis symptoms (twice daily application for three months reducing them by over 70%)
|
|
|
Inositol |
Minor
|
- See study |
Lithium-induced psoriasis is reduced with supplemental inositol at 6g daily. Inositol may only be effective in this particular scenario
