Source Naturals, N-Acetyl Cysteine, 1000 mg, 120 Tablets40 Reviews
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.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

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.

iHerb Customer Reviews
I have been taking NAC for months now, and I appreciate the larger 1 gram size, also need to up my vitamin c dosage to 3 grams with this monster, otherwise it can cause more bad than good. Strong sulfur odor lets me know it means business.
I have/had a 30% hearing loss from family genetic predisposition. I've been taking this supplement for 3-4 months now and I believe there has been definite improvement. Maybe a 10%-15% reduction. I've stopped using my hearing aids and though I still have trouble hearing I'm picking up much more conversation than I did in the past. I'm 54 but I think this is definitely worth a try. This substance was supposedly tested by the US Navy to help prevent hearing loss onboard ships but it has also helped me.
