10 Best Hormone & Sexual Health Supplements

By The Supplement Ratings editorial team6,310 products analyzed

Hormone, sexual and reproductive health products span saw palmetto for prostate support, fertility formulas, menopause support and testosterone boosters. It is also the category with the most FDA warnings about products containing undeclared drugs, which makes a complete, specific label worth more here than anywhere else.

We ranked every hormone, fertility, menopause, prostate and thyroid-support product sold on iHerb by label quality.

How we ranked them

Every product is scored 0–100 from its label data in the NIH Dietary Supplement Label Database: dosage transparency (35 points - are amounts stated per ingredient, or hidden in a proprietary blend?), label completeness (25), formulation cleanliness (25 - fillers, dyes, titanium dioxide and other non-active ingredients) and ingredient profile (15). The Top 10 admits only products scoring 60 or higher; among those, products with a verified retail listing are shown first so the list is one you can act on. No brand can pay to be included or moved up.

Forms and dosage

Saw palmetto: Studied mostly at 320 mg a day of extract; labels should state the extract and its fatty-acid standardization.
DIM and indole-3-carbinol: Compounds from cruciferous vegetables, sold for estrogen balance.
Fertility and prenatal-support formulas: Often inositol, CoQ10 and vitamins; amounts per ingredient should be stated.
Herbal libido and testosterone formulas (maca, tribulus, tongkat ali): Frequently sold as proprietary blends.

How much to take

Doses are ingredient-specific and mostly come from small studies: saw palmetto 320 mg, DIM 100–200 mg, myo-inositol 2–4 g per day. Thyroid formulas with iodine should state the amount; the NIH upper limit for iodine is 1,100 mcg per day.

Frequently Asked Questions

Are testosterone booster supplements safe?

Many herbal ones are low-risk at labeled doses, but the FDA has found prescription drugs hidden in some "male enhancement" products. A fully disclosed label from an established brand lowers that risk; our score rewards disclosure.

Can supplements replace hormone therapy?

No. Our ranking judges how well a label is written, not whether a product treats any condition.

How are hormone & sexual health supplements ranked?

Products are ranked by SupplementScore, which evaluates label quality across four categories: dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts). The score is based on data from the NIH Dietary Supplement Label Database, not marketing claims.

Does a higher score mean the supplement is more effective?

No. The SupplementScore measures label quality, how transparent, clean, and well-documented a product is. It does not measure clinical efficacy, bioavailability, or third-party testing. A higher score means better label practices, not guaranteed results.

How many hormone & sexual health supplements were analyzed?

We analyzed 6,310 hormone & sexual health products from the NIH DSLD database, which contains label data for over 116,000 dietary supplements sold in the United States.
