Seen a claim about a supplement somewhere — a "best-seller" badge, an ad, something on social media? See what the evidence Herology has already reviewed says about it.
The best-selling creatine on Amazon (30,000+ ratings). Solid basic product.
Not third-party certified, and the label follows the standard 20g/day loading protocol most women don't need.
ProbioticsOne of Amazon's best-selling probiotics (100,000+ bought/month). High CFU count and 10 broad strains for general digestion — solid for gut health.
None of its listed strains are the ones studied for vaginal/urinary health.
MagnesiumAmazon's best-selling magnesium (20,000+ bought/month). Cheap and fine for occasional constipation.
The poorly-absorbed form — not the one studied for cramps, PMS mood, or sleep.
IronThe default drugstore iron pill. Effective.
The highest-GI-side-effect form in head-to-head trials — a common reason people abandon iron supplementation before their levels recover.
Anxiety / MoodA popular, well-reviewed generic saffron extract.
Not the specific 'affron®' branded extract used in the PMDD trials, so the exact evidence doesn't transfer one-to-one.
PrenatalThe standard, most widely used OTC prenatal (#1 OB/GYN-recommended OTC brand). Solid folic acid, DHA, and iron coverage.
Essentially no choline, like most prenatals in this price tier.
