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.

Natural Factors Glucosamine Sulfate is the most effective form of this product I've ever used. My sacrum "went out" several years ago and after many chiropractic adjustments was still sensitive and I had to be very careful how I sat and what I sat on. After taking Natural Factors Glucosamine Sulfate, my sacrum feels stronger and does not slip out of alignment. I have tried other brands, but Natural Factors seems to go right to work quickly. iHerb.com is highly reliable and fast at getting your order to you. I will definitely be ordering from them again.
