Great for detoxing

I think this is the best form of NAC on the market. NAC is the precursor to reduced glutathione. This helps the body detox many different substances. I'm chemically sensitive and have elevated copper levels, and this has helped with both conditions.

Jarrow Formulas, NAC, 600 mg, 100 Tablets

Clinical research has proven that L-cysteine is safer to take on a daily basis than sustained-release NAC; this powerful antioxidant should be cycled and should not be taken continuously. Please note that NAC is an altered version of L-cysteine and thus has the potential for more side effects. Please use NAC with caution and tell your physician you take this product.

Makes aging a little easier

As a precursor to glutathione, a major detoxifier in the lungs and liver, NAC helps in everyday living. But NAC itself helps to breakdown alcohol directly and makes hangovers all but disappear. I recommend taking two before drinking with a full glass of water and two before going to bed. The next morning will be too late!!! Have fun thirtysomethings!

Liver health and sinus health, too

I've had "liver problems" my whole life -- every time a doc wants to start me on a new drug, we test my liver. I've been taking NAC Sustain for a few months, and my most recent liver panel came back clean. My doc actually said "wow." Go figure. Also, not sure about the mechanics of this, but suffer from Sinus pain and have to stay on top of it -- until I started NAC Sustain -- I can always tell when we run out -- sinus pain returns. As long as I stay on this formula, no Sinus problems. Amazing. I usually take 2-3 at night before bed, and then another 1-2 tabs in the morning before food. This stuff is amazing.

The best NAC SUPPLEMENT, and one of the best free-radical fighters,

The time-release function of this supplement really hits on target for creating a superior formula. MAke sure you take this if you care at all about oxidation in your body. Many antioxidants are very useful, and target different free-radicals, in different parts of the body. However nothing, even arguably ALA, can come close to the effects of NAC! Nac's action on the human system is global, and it has hundreds of receptors for free-radicals once converted to GLutathione. Other anti-oxidants don't approach this! Take with Alpha-lipoic acid to help recycle protection further. I would also says Ascorbyl Palmitate is a good idea! My usually pale skin was visibly pink again within days to to the positive action of NAC. It does wonders for the skin and hair.
