it seemed to help with my chest cold - although beware passing of gas near anyone nearby for the aroma may be an unpleasant experience for anyone, including yourself. And I know sometimes it doesn't bother you, in fact you may take pride in it, but this will be different.

n-acetylcysteine. Smells like the real deal if you break a capsule open. Same gastro effects if you mega dose it. I obviously didn't send it to a lab for testing but I feel certain it contains NAC. iykyk, pleiotropic benefits. Cheap, easy way to access it if you run out of a more expensive brand from some of the more "high end" supplement companies. Would recommend

Connor September 27, 2025

I was told NAC supplements have shown promise in reducing cravings for alcohol use disorder while at a treatment facility. It's only my third day but I'm noticing an increase in energy levels and reduction in cravings. It's still early but initial results are promising. I'm also noticing a clearing "brain fog" which I'm hopeful will continue to improve. Very happy so far.

NAC works for me

Sparky July 10, 2026

Supplements are a debated topic, some say they don't work while others sing praises.. My experience has been that ever since I started taking NAC regularly-kind of regularly I have had no injury get infected and have had no colds or flu other than when the wife and I had a very mild case of the COVID where we lost the senses of taste and smell for over a month.. We never had more than a low grade fever and maybe a few sniffles and a few coughs.. In my mind I credit the NAC for giving us stronger immunity systems over the past 6 years.. One capsule in the morning with a glass of water or coffee or 1 in the morning and one before dinner with a glass of water during cold and flu season..

⭐️This is one of my go-to purchases, as I've experienced positive health benefits since starting to take it. The synergistic effects of all the ingredients enhances its overall effectiveness.

Recommend!

Holly June 1, 2026

I added this to my suppliments to help rebuild my immune system and gut health. It has been a good addition, the price is reasonable, and it is easy to take. I would recommend, it is cheaper to buy here than other places which is nice too.

Straight up smells like flatulence

Jaimee May 15, 2026

I was born with a genetic autoimmune liver disease called Primary Sclerosing Cholangitis, which has no real cure or treatment besides getting a transplant. I would like to avoid that at all cost, living out the rest of my life with the liver I have. I read that this is good for liver support and have added it to my supplements. IT SMELLS LIKE flatulence IT TASTES LIKE HOW A flatulence SMELLS WHILE INSIDE MY MOUTH. I am willing to overlook that aspect due to my circumstances ….if you don't have liver disease, you can be nit-picky about it 🤷‍♀️. Again - I am trying to avoid a massive life-changing transplant surgery, so I am choosing not to be picky . It sucks for a minute and then I move on with my life…. Just be warned LOL

It is a stronger mg dose for trying for the 1st time, so I it is pretty powerful @2 at once. It stinks and I hate capsules, all in all, it's what my healthy ordered!!

Sleepy October 4, 2025

I am an avid supporter and user of NAC (Jarrow, NOW, etc) for many years. I needed some fast to clear up my chest congestion (great for COPD!) so I ordered this brand. I expected that it may not be as good a quality as Jarrow my go to, but I thought it would at least work, but not a chance. NAC usually clears me up within 24 hours, but it didn't and the notorious odor that is expected with NAC isn't there. It smells like they added garlic to make it stink, but it's not the typical odor one would expect. I hope to get a refund and I don't recommend this NAC product at all.

Terrible!

Jamie November 27, 2025

Rancid smell. Very sulphuric. I took a total of 3 doses over 2 days and ended up severely bloated and constipated. And once I finally went to the bathroom it smelled like a sulphuric burnt rubber leading me back to this vitamin. I do not recommend this to anyone.
