The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

Despite the instructions to take this with meals, it should actually be taken between meals with an activated B-6 tablet and 50+ mg of vitamin C in order to get the greatest benefit. If you smoke, this is an indispensable product and this brand is as effective as any of the more expensive brands I've tried. Aside from increasing your body's production of glutathione, essential for liver protection, NAC is particularly effective in clearing your lungs of damaging carcinogens or any other detrimental pollutants. In fact, if your dog is dumb enough to go after a skunk and gets sprayed, and you take it to the vet, the first thing the vet will do is give it a 1K mg shot of NAC to clear its lungs of the spray, which can be toxic due to its preventing your dog's ability to breathe with that oil covering the oxygen intake cells. So, for liver or lung protection/healing, NAC is essential and well worth the relatively minor expense, considering the benefits reaped from taking it in contrast to the damage done if you don't use it regularly. I was surprised that this brand worked as well as it does - just as well as any of the more expensive brands I've tried over the years - and its effects were immediately noticeable, so I would recommend 2 tabs/day taken separately between meals for anyone needing the benefits of NAC. (If you smoke, you will cough more because your lungs are being cleared of tar.)

since most NAC's sources comes from birds feathers,hog bristles or even human hair, I contacted the manufacturer and asked them about the sources and they confirmed it's "synthetic" that was a relief; NAC is the second important supplement for me after Vitamin D, helps with many things and over all well being; quality product with a decent price.
