Cysteine is a non-essential sulfur amino acid, which plays a critical role in methionine, taurine and glutathione metabolism.* It is also an important component of hair, nails and the keratin of the skin. Cysteine stabilizes protein structure and aids in the formation of collagen, being thereby indispensable to skin, hair and nail health.*

Really helps with hair loss
After consulting everyone and their mother for YEARS, up to and including paying to see one of the top dermatologists in NYC, I ran into a woman in a vitamin shop in Loveland, CO. She recommended 1000 mg/day of L-Cysteine and 2400 mg/day of Biotin, and she saved me. At that point, I literally had bangs I didn't cut -- my hair was breaking off and falling out all across the front of my head. I've been taking those two supplements daily for a dozen years now. If I stop, the "male pattern" hair loss starts right up again. My hair isn't thick in those spots, but it's not sparse, and best of all, it's not gone.

Great product but bottle makes storage a pain
Ordered this many times. Great and easy to use. I wish it were in a bag and not in a plastic bottle, otherwise it is good.

It's a health supplement
It's reasonably priced and hopefully does what it's intended for. It's a health supplement, nothing more.
