Biotin is a B vitamin that plays several roles in energy metabolism, gene regulation, and cellular activity.
It’s found in animal-based foods, nuts, and seeds. Deficiency, which is characterized by brittle nails, skin rashes, and thinning hair, is uncommon.
However, you may need to supplement with biotin if you have biotinidase deficiency or chronic alcohol use disorder, as well as if you’re pregnant or breastfeeding.
Live Extension Biotin is vegetarian and non-GMO, as well as third-party tested by NSF International.
Per serving, this supplement from Life Extension provides 2,000% of the DV for biotin. This is a relatively low dose compared with most other biotin-only supplements.
Several reviewers mention that taking the vitamin has helped strengthen their nails, though others note that it took close to 1 year before they noticed improvements.
Still, despite anecdotal reports, keep in mind that there’s minimal evidence to support the effectiveness of biotin for hair and nail health.
This organic, gluten-free, non-GMO, and vegan-friendly supplement is designed to promote collagen synthesis and improve the appearance of your skin.
In addition to biotin, Garden of Life mykind Organic Plant Collagen Builder contains several other vitamins, minerals, and botanicals that may help support healthy hair and skin, such as silica and vitamin C.
The supplement is also third-party certified gluten-free by NSF International, making it safe for those with a gluten-related disorder.
