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. ## Frequently Bought Together - NOW Foods Supplements, L-Cysteine 500 mg with Vitamins B-6 and C, Structural Support*, 100 Tablets - DHM1000 Dihydromyricetin (DHM) Tablets - Most Powerful DHM Supplement on The Market - 1,000mg (30 Count) Enhanced with Electrolytes for Hydration and Liver Support by Double Wood - Bronson Milk Thistle Silymarin Marianum & Dandelion Root Liver Health Support, Antioxidant Support, Detox, 120 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/2576147-now-foods-supplements-l-cysteine-500-mg-with-vitamins-b](https://www.desertcart.sg/products/2576147-now-foods-supplements-l-cysteine-500-mg-with-vitamins-b) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-21*
