NAC is a great supplement but this one contains plastic!

I noticed too late there is polyacrylate in this product. That's plastic! I switched to another brand because i don't think eating plastic is good for anyone. Otherwise NAC is a great supplement: removes toxins from your body by helping liver to work as it should. Great hangover medicine as well :) <br /><br /> <font color="red"><strong>August 2012 - Note form Jarrow Formulas:</strong></font> The polyacrylate polymer is GRAS. The material is widely used in dietary supplements although can be represented in multiple ways on a label including the trademark Carbopol, carbomer homopolymer and carboxypolymethylene. Finally, the research indicates that due to its size, the polyacrylate polymer employed in this product is not absorbed through the intestines and therefore poses no safety concern.  There is a very good reason for NAC Sustain:  The half-life of NAC is relatively brief.  Carbopol is a biomucoadhesasnt.  It keeps the tablet at the site of maximum absorption, at or near the upper small intestines.  The tablet slowly erodes, thus there is a continuous release for a couple of hours instead of the whole thing being essentially gone in one hour.  The tablet can take up to two hours to release the contents plus the hour of half-lives, thus the dose lasts three hours or more.  This gives a real boost to the production of GSH (glutathione) and the Phase I detoxification pathway of the liver.  If one chooses to not utilize the benefits of Carbopol then the standard <a href="http://www.iherb.com/Jarrow-Formulas-N-Acetyl-L-Cysteine-500-mg-200-Capsules/235" target="_blank">Jarrow Formulas NAC capsule</a> is also an option.  <br />

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.

My doctor prescribed a theraputic dose of NAC to aid with a lung condition. It always gave me a headache, until I began using NAC by Jarrow. With their sustained release product, I no longer get the headaches.
