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.
My Guarantee
I've taken the decades I've spent in school, the lab, the gym, and the kitchen and distilled them into the very product you hold in your hands. I formulated every JYM Supplement Science product to include the same ingredients at the exact amount I use to reap maximum performance and physique benefits. It's my hope that you, too, will experience similar results.
