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.

I'm a female in my very early 30's and an inexplicable case of hair loss that no doctor or blood test seems to be able to detect 'medically'. Purchased NOW L-Cysteine after my dermatologist recommended it to me as a non medical solution. Seems to be working after 5 months of religious use - new hairs are sprouting all over my head.
I bought this as an alternative to NAC for liver detox and support, because it is good to pause or alternate ALL supplements. Now I discovered on Dr. Mercola & Wikipedia that 80% of it is made from hair swept up in chinese barbers. Then from duck feathers and hog hair. It can also be made from fermentation, but is 3X as expensive. Some sites also say it is a brain excitent which eventually burns out the brain if taken in high doses. On NOW's site, they offer no info on their source, but offer the absolute cheapest L-Cysteine. Anyone know of a non- hair source? I give it 3 stars until I know more. Also of concern is the general lack of details re ingredients on their labels. For instance: There are over 4 kinds of vitamin K-4. Menaquinone 4, 7,8 and 11. Only the Menaquinone 7 is of true value for humans. The others are inexpensive or synthetic forms of no true value. Now Foods has a large number of vitamin supplements that avoid telling us exactly what we are getting. And I am getting more suspicious of this company for this evasive strategy.

I tastes like rotten eggs, which makes it very difficult to swallow. So I gave up before I could see any effect.

A lot like Acetium and preatty much the same stuff, as I've understood it. Not necessarily as "potent" but a good product never the less.
