great best deal. some customers get a problem with one item (it happens) they dump all their life's burden at the brand. I have been using the company for years, they offer fantastic blends, generous mg amounts and serving at great prices. this is a very nice combo here as well. I use now and jarrow and enzymatic therapy, and doctor's best. NAC is sulfur, you can try sustained form by jarrow.

Previous review wrong
NAC is a sulphur compound and all brands smell like rotten egg or the like. Product is not spoiled.

I have used NAC products from other brands. Due to the low prices of Doctor’s Best, I decided to give it a try, but I was very disappointed. Half way to the end of the bottle, the ingredient inside the capsules has turned yellow and IT SMELLS AWEFULL!! The first thing I did, I checked the expiration date, but it was 2017! The ingredient has two years to expire but it has already rotten. I never had this problem with other NAC products even the ones that come in capsules such as NOW. Doctor’s Best needs to understand that they cannot fool consumers. Even if they put the word BEST ten times on their labels, people will notice the difference when a product has inferior quality. I do not recommend this product to anyone and I will not try Doctor’s Best products again, bottom line is that it was a very disappointing experience.
