L-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. L-Cysteine stabilizes protein structure and aids in the formation of collagen, being thereby indispensable to skin, hair and nail health.

Great results

I've had a deep chest cough for months that cleared within 2 weeks of taking L-Cysteine.

Thanks for your feedback!

Thanks for your feedback!

Thanks for your feedback!

helps with BP

Posted by iHerb Customer on Aug 28, 2017 | Verified Purchase

I got this for my wife's thinning hair, as i know with other people that it helps. What surprised both of us (wife & myself) is that it lowers and stabilizes her blood pressure. After three weeks of taking 2 capsules twice per day, her BP is now perfect, something her BP medications were unable to do for many years. Needless to say we are elated with the results. It would take a touch longer to see good results with her hair, but we are sure these will come as well.

Thanks for your feedback!
