8 Best Biotin Supplements

Best biotin supplement for hair health

OLLY Ultra Hair

• Type: softgel
• Dose: 1 softgel provides 10,000% of the DV

OLLY Ultra Hair is formulated to promote strong hair, prevent breakage, preserve pigment, and encourage hair growth.

Each serving contains a high dose of biotin, along with vitamin D, folate, vitamin B12, zinc, copper, keratin, amla fruit extract, and silicon, some of which are purported to boost hair growth, though the research is mixed.

The product is highly rated by reviewers, and it’s third-party tested by NSF International to ensure purity and potency.

Keep in mind that as the capsules contain gelatin and beeswax, this supplement isn’t suitable for those following a vegan or vegetarian lifestyle.

Best hair, skin, and nails biotin supplement

Pure Encapsulations Hair, Skin, and Nails Ultra

• Type: capsule
• Dose: 2 capsules provide 20,000% of the DV

Pure Encapsulations is a trusted supplement brand among health professionals. Its ingredients and products undergo rigorous testing by a number of third-party labs, such as Silliker, Eurofins, Covance, and Advance Laboratories.

This supplement contains 20,000% of the DV for biotin per 2-tablet serving, along with a number of other active ingredients to support hair, skin, and nail health, such as silica, collagen, zinc, and coenzyme Q10 (CoQ10).

Note that high doses of biotin don’t appear to pose a risk of toxicity, although they may interfere with lab testing.

When taken at high doses, excess B vitamins are typically flushed out via your urine. However, it’s possible that there simply hasn’t been enough research on the potential side effects of taking too much.

Regardless, be sure to clear a high dose biotin supplement like this one with a healthcare professional, especially if you plan to take it over a long period.
