The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect dht.
| 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.
|
Supplement |
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.

- See study |
An increase in DHT independent of an increase in testosterone has been noted, but the study requires replication due to some potential issues (its location, the lack of biological plausibility, etc.).

Minor
|
Very High See 2 studies |
May increase DHT levels alongside testosterone levels, but this has only been observed in postmenopausal women

Minor

Moderate See 2 studies |
A decrease in DHT has been noted following consumption of fenugreek seeds in otherwise healthy men, but appears to be unreliable
