Cysteine stabilizes protein structure and aids in the formation of collagen, being thereby indispensable to skin, hair and nail health.* Natural color variation may occur in this product Review: DIGESTIVE ISSUES? - I purchased this supplement to help keep my intestines health. I am pleased with results. Helped my digestive system get on a consistent daily cycle. Great price, quantity, quality tablets are a little large but still easy to swallow. Review: Seems to prevent mega-hangovers at least, may help other things - I don't think that science has fully confirmed this, but my impression is that this supplement helps a lot with hangovers. In my experience, it won't really prevent them, but it does seem to help avoid catastrophic hangovers from a really big night. I used to get 36-hour hangovers sometimes and those don't ever seem to happen if I take at least one of these at the beginning and the end of the night. So I keep these around mostly for that purpose, but they might possibly have some other benefits. It tastes pretty bad so don't let it linger in your mouth before swallowing. It's smooth and about the size of a multivitamin so it goes down easy. The theory that led me to this is that this supplement helps your body metabolize acetaldehyde. With a balanced diet, it probably doesn't do much, but in brief periods of having a very unbalanced diet, like a bachelor/bachelorette party, I think it helps. And I've definitely never experienced any side effects from taking this supplement, so I consider it cheap insurance. ## Features - STRUCTURAL SUPPORT*/WITH VITAMINS B-6 AND C: Cysteine is a non-essential sulfur amino acid, which plays a critical role in methionine, taurine, and glutathione metabolism* - NON-GMO TABLETS/HEALTHY SKIN, HAIR, AND NAILS*: 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* - CERTIFICATIONS/CLASSIFICATIONS: Soy Free, Non-GMO, Nut Free, Made without Gluten, Dairy Free, Egg Free, Halal, Kosher - GMP Quality Assured: A-rated, third-party certification means that every aspect of the NOW manufacturing process has been examined.

L-Cysteine can directly participate in glutathione synthesis, whereas N-acetyl-L-cysteine must be first de-acetylated (i.e., broken down) before its incorporation to glutathione. Cell studies have shown L-Cysteine to be more effective in increasing cellular antioxidant glutathione levels. However, L-Cysteine is less stable than NAC so oxidizes more readily in the body. To help prevent or slow this process, 3x more ascorbic acid (vitamin C) should be consumed. So for every 1g L-Cysteine consider taking 3 g Vitamin C. **Q: I read an article about a new study saying this will cure hangovers. Thoughts?** A: I read that article and bought a bottle to try. It works! Absolutely amazing hangover cure that actually works. I get hangovers from just 2 glasses of beer normally and now I get virtually none. I just take 2 tablets each time I drink and may take another if I go hard. If I drink too much and forget to take a 3rd tablet, I may have a very mild headache the next day, which is much improved from being out for the count all day like I used be after drinking. My boyfriend and roommate can also attest and ask me for some whenever we have some drinks together. All I can say is, just try it. You'll be amazed. **Q: Is it made of human hair? If surprised read about L cysteine or E920(another name) on internet** A: Apparently synthetic L-Cysteine is expensive to manufacture, so human hair, duck feathers and pigs' bristles can be used. Whether NOW's L-Cysteine is a product of human hair it is not clear. **Q: Is this product vegan?** A: It is most commonly derived from human hair. ## Customer Reviews ### ⭐⭐⭐⭐⭐ DIGESTIVE ISSUES? *by F***N on January 26, 2026* I purchased this supplement to help keep my intestines health.
