Metabolic Maintenance, NAC, 600 mg, 60 Capsules4 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.

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.
