Our verdict
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.

WEEM is a small Los Angeles brand whose vegan Hair.Skin.Nails gummies launched in 2020. Two raspberry-flavored pectin gummies deliver 5,000 mcg of biotin (16,667% of the Daily Value) plus vitamins A, C, D, E, B6 and B12, folate, pantothenic acid, 2.7 mg of zinc and 42 mcg of iodine, with 20 calories and 3 g of added sugar. The extras range from 22% to 250% of the Daily Value, so it behaves more like a modest gummy multivitamin than a hair-specific formula, and the inositol (40 mcg) and choline (0.04 mg) amounts are token.
The evidence for the headline ingredient is weak. NIH's Office of Dietary Supplements says biotin's hair, skin and nail claims rest on a few case reports and small studies, and a 2017 review found every reported benefit involved a deficiency or underlying condition. A dose this high also matters for blood work: the FDA has warned since 2017 that biotin can distort some lab tests, including falsely low troponin results, so tell your clinician before any blood test.
The label carries a GMP seal and WEEM says the gummies are made in the US, but we found no named third-party testing. The current label misprints vitamin D as 10 mg (its 50% Daily Value matches 10 mcg), and the gummies are colored partly with titanium dioxide, which European regulators no longer consider safe as a food additive. At $30 for a 30-day bottle on the brand site, it costs about $1 a day, several times the price of mainstream biotin gummies. Buyers consistently praise the taste and many report faster nail growth and less shedding, while recurring complaints include no visible change after months, an off smell or taste in some bottles, and subscription and refund problems.
| Key ingredient | Per serving | Why it matters |
|---|---|---|
| Biotin 16,667% of the Daily Value; benefits are documented mainly in deficiency, and intakes this high can skew some lab tests, including troponin. | 5000 mcg | 16,667% of the Daily Value; benefits are documented mainly in deficiency, and intakes this high can skew some lab tests, including troponin. |
| Zinc (from zinc citrate) 25% of the Daily Value; zinc deficiency can affect hair, but this is a small top-up. | 2.7 mg | 25% of the Daily Value; zinc deficiency can affect hair, but this is a small top-up. |
| Vitamin A (as retinyl acetate) 70% of the Daily Value as preformed vitamin A; worth counting if you also take a multivitamin. | 630 mcg RAE | 70% of the Daily Value as preformed vitamin A; worth counting if you also take a multivitamin. |
| Vitamin D2 (as ergocalciferol) The label's 50% Daily Value figure corresponds to 10 mcg; the printed '10mg' appears to be a typo. | 10 mcg (label prints 10mg) | The label's 50% Daily Value figure corresponds to 10 mcg; the printed '10mg' appears to be a typo. |
| Folate 108% of the Daily Value, a standard multivitamin amount. | 433 mcg DFE (260 mcg folic acid) | 108% of the Daily Value, a standard multivitamin amount. |
| Inositol A token amount; it adds marketing appeal rather than a meaningful dose. | 40 mcg | A token amount; it adds marketing appeal rather than a meaningful dose. |
