Product Overview


  • Dietary Supplement
  • Hypoallergenic

Biotin is a water-soluble B vitamin that can have a beneficial effect on a number of structures and functions in the body. In a clinical trial, 45 patients with brittle fingernails received oral supplementation of 2.5 mg biotin for 1.5-7 months. Ninety-one percent showed "definite improvement," exhibiting firmer, harder fingernails after an average of two months of supplementation.

Biotin in a higher amount, such as Is present in Thorne's Biotin-8, supports glucose metabolism by stimulating glucose-induced insulin secretion in pancreatic beta cells and by accelerating glucose metabolism in the liver. Biotin also enhances muscle insulin sensitivity by increasing uptake of glucose by the muscle cells.

Suggested Use

Take 1 capsule one to two times daily or as recommended by your health-care practitioner.

Microcrystalline cellulose, hypromellose (derived from cellulose) capsule, silicon dioxide, leucine.

iHerb Customer Reviews

Great quality product, good for nails

Posted by iHerb Customer on September 30 2017 | Verified Purchase

Thorne is reliably a high quality product, and this was no exception. Has made an observable difference to the strength of my father's nails which he needs strong for playing the guitar. Other brands of similar product lines had no measurable effect.

Thanks for your feedback!

Nice small capsule AND great effects!

Biotin is one of the B vitamins, and as such is best if combined with a B complex or a diet high in B vitamins. I am trying Biotin to help with energy, skin, hair and nails, and also tolerance of carbohydrates. Actually, I quite surprised how well it is working. It seems to keep the opportunistic yeasts (such as Candida albicans) in check, even if I do have a little date in a homemade treat creation. Normally, I would feel very tired, my tongue would quickly develop a thick coating and perhaps I would get an itch here or there. Also my skin texture seems to have improved a little. Also this past week, I have been able to eat a little potato and even a little quinoa. Both of these are usually badly tolerated. Definitely worth a try!

Thanks for your feedback!

This will take some time

I will update in due time, however, I do notice my normally paper thin nails are not bending so easily. Edited to Add: I am switching to whole food vitamins/minerals.

Thanks for your feedback!
