Nature's Bounty Biotin Hair Skin & Nails Vitamins

Our verdict

Nature's Bounty Biotin Hair Skin & Nails Vitamins works out to $0.22 per serving of biotin (vitamin b7), at 10000mcg per serving in softgel form. That puts it above the median of the 91 biotin (vitamin b7) products we can price per dose, where the typical serving costs $0.12, a Value Index of 0.5 where the median product is 1.0. One container lasts 120 days at the label dose of 1 serving a day, about $6.66 a month. We could not verify a third-party certification for Nature's Bounty in a public registry.
