Pros and cons
Hair Growth Supplement
- AminoMar marine complex (1,072 mg) with trial data
- Favorable mention in a 2023 JAMA Dermatology systematic review
- Full label disclosure with modest 240 mcg biotin
- Recommended by board-certified dermatologists on TikTok
- About half Nutrafol's monthly cost
- No named third-party certification
- Trials are small and company-funded
- Some buyers report stomach upset or constipation
- Marine ingredients (oyster extract) rule it out for shellfish allergies
Hair Skin and Nails Gummies
- Vegan pectin gummy, free of gelatin and gluten
- Fully disclosed label with no proprietary blend
- Adds vitamins A, C, D, E, B6, B12, folate and zinc at mostly moderate doses
- Buyers consistently praise the raspberry flavor and soft chew
- Brand advertises a 100% money-back guarantee
- 5,000 mcg of biotin has little evidence for hair or nails in people who aren't deficient and can distort some lab tests
- About $1 a day at the brand's list price, several times the cost of mainstream biotin gummies
- No named third-party testing; the label misprints vitamin D as 10 mg and uses titanium dioxide for color
- Marketing promises to fight hair loss and heal the scalp, which the evidence does not support
Our verdicts
Hair Growth Supplement
One of the better-supported hair supplements, with a transparent label and a sensible biotin dose, at a lower monthly cost than Nutrafol. The evidence is still small and company-funded and there is no third-party certification, so treat it as a three-to-six-month experiment alongside a proper diagnosis.

Hair Skin and Nails Gummies
WEEM is a pleasant-tasting vegan gummy with a broad, fully disclosed vitamin label. Its signature 5,000 mcg of biotin, though, is unlikely to change hair or nails unless you are deficient, the marketing goes well beyond the evidence, and at about $1 a day it costs far more than comparable biotin gummies. If you want to try biotin, a cheaper product does the same job, and new or patchy hair loss deserves a clinician visit first.
