Estrogen

Known as the female hormone, 'Estrogen' is a group of compounds that tends to work in opposition to androgens (like testosterone) and mediate fat metabolism, cognition, blood flow, and female reproduction. Men sometimes wish to lower estrogen via aromatase inhibition.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect estrogen.
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 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.
Notes
grade-a Notable High See all 14 studies
There appears to be a notable and unreliable increase in estrogen following DHEA supplementation, with most research being conducted in menopausal women. This increase in estrogen has been noted in men as well, although similarly unreliable.
grade-b Minor - See all 8 studies
It's possible that it can increase estrogen in postmenopausal women, and some studies suggest a considerable increase, though the evidence is weak and inconsistent. More research is needed to determine its effects in postmenopausal and premenopausal women.
grade-b - Very High See all 6 studies
Regardless of any direct estrogenic effects (which also do not appear to occur) there are no changes in circulating estrogen seen with oral supplementation of red clover extract.

Frequently Asked Questions and Articles on Estrogen

Is soy good or bad for you?
Moderate consumption of soy foods is unlikely to have adverse effects in adults; it may even benefit cardiovascular health and reduce cancer risk. Eating large amounts of soy foods for 6 months or more, however, may cause problems. Also, the use of soy infant formulas should probably be minimized.
