Metabolic Maintenance, NAC, 600 mg, 60 Capsules5 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.

iHerb Customer Reviews
Internet sources indicate that most NAC is manufactured in China using cysteine from animal protein, mostly through the hydrolysis of human hair or poultry feathers. I contacted Metabolic Maintenance to inquire about the manufacturing source of their NAC. While they would not identify the exact manufacturer, they did say that it was manufactured in Japan by synthesis (ie. not from human hair or feathers). This may explain why NAC of other brands costs less than that from Metabolic Maintenance. Because of this and because Metabolic Maintenance does not use any fillers in their NAC product, I prefer this brand for NAC.
I bought this based on the first review because I had not found an NAC I could tolerate and this one did not have anything in it that is problematic for me. Yes, it's more expensive than the others, but I am glad I got it, as it's the only one that I seem to tolerate out of all the ones I have tried. A big thank you to the person who wrote the other review and said what the difference was with this product. My doctor wanted me to take 600 mg once a day, and now I'm glad that I can!
