Product Description

Size: 120 Tablets

Dietary supplement. Antioxidant support. N-Acetyl cysteine is a stable form of the sulfur amino acid l-cysteine, and is a powerful antioxidant. It is also a precursor of glutathione, a major antioxidant. Glutathione is activated by the selenium-containing glutathione peroxidase, one of the most important antioxidant enzymes in the body. N-Acetyl cysteine is better than glutathione supplements, which may break down during digestion and lose potency. (These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.) Hypoallergenic: Contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

I am breathing better and I feel better.

Some people may not benefit from this, but I certainly have, and I encourage everyone to give it a try.

NAC really only comes in 600mg tablets other than this tablet.

First review May 2013
After reading the claims and reviewing the actual studies, I decided to try these to see if it improves my asthma and frequency of infections as claimed.
Other reviewers commented on the smell and they are 100% correct! Do NOT smell the contents of the bottle or you'll likely throw them away. (LOL! Trying to maintain acceptable language here)-- It smells like concentrated colon gas after eating a can of beans. Understand? But us old-timers recall old medicines usually tasted nasty and learned how to deal with it. Bite the pill between you teeth, then quickly down it with water. Avoid holding it in your mouth. Hey, it's nowhere nearly as bad as 1950-60's penicillin or the spoonfuls of code liver oil... BLAH!
Update May 2014
An update after using this product for a year and I'm happy to report I am doing MUCH better! Absolutely NO - ZERO upper respiratory tract infections this year and this has NEVER happened to me!!! Even my doctor was impressed. I am not one who eats supplements without doing my homework- checking the valid studies. This one passes the test.
Before starting this I did a lot of research, reading studies by pulmonologists. According to most, all patients with COPD should be on NAC, as it's benefits have been proven. A great resource is nih.gov... just type in the search line: NAC + COPD. They tested subjects with 600mg, then 1200mg. The best results were found in the group taking the higher dose. This brand is 1000mg, which for me is close enough.
BTW, regarding its awful smell- it helps to leave the lid off the bottle for a while.
I should also mention these are huge horse pills. Some may need to break them in half with a pill cutter, as they are not scored.

N-Acetyl-Cysteine is what they use for people who have liver poisoning or Tylenol (liver damage). This is one of the reasons I bought it, my liver is failing from years of Chemotherapy and chronic (high) Tylenol use. While I am NOT a doctor and cannot claim that this "saves lives" it HAS helped my liver begin to regenerate some and ease some of my symptoms. I am still under the care of a Hepatologist (Liver specialist) but if you have ANY kind of liver damage or problem (Cirrhosis, fatty liver, chemotherapy damage, etc) then this is a product that certainly cannot hurt.

I received my product very quickly, and Source is a good company. The pills ARE very "bitter" and large, so you can either break them in half or follow maybe with a bit of applesauce? But do not be surprised at the bitterness. If it wasn't so bitter I would give it a 5 star rating. I normally take 3 of these a day.

I starting using this product right away. I take 2 pills per day, one in the morning and one at night. Instantly, it helped my craving for cigarrettes. In the last two days, I have smoked only 10 cigarettes, when, normally I would smoke a pack and a half per day.

I highly recommend this product.

Well my liver is not a happy camper so doc suggested these. They smell like cat poo but they are apparently working as I am still on this side of the turf. :-)

NAC is the only thing that seems to help at all with my endometriosis and migraines. I would be dealing with migraines 24/7 without it. This brand works better for me than the NOW NAC does. The NOW NAC started to give me an upset stomach for some reason and this brand does not.

NAC really only comes in 600mg tablets other than this tablet. So convenient to have the 1000mg dose. Very fast shipping, reliable (I order this product regularly) service and absolutely no stomach upset with this product even when taken outside of meal time. Other brands give me a stomach ache if I do that.

I have pulmonary fibrosis (a progressive lung disease) and was told, 4 years ago, by my Pulminologist to take this. Studies show that this antioxidant removes free radicals and helps to keep this disease from progressing. So far so good. It always arrives promptly.
