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.

Calms your mind and makes you focus better. Reduces anxiety and helps you step away from overwhelming situations to resolve them better. Also helps when taking with Doctor's Best L-Tryptophan for sleeping. As this product works on a brain level (got this from the great nutritionists at Doctor's Best), it helps calm the brain and the L-Tryptophan helps on the hormonal level. Best sleep i've ever gotten and all night too. I have put my entire office on the Doctor's Best Suntheanine L-Theanine product. As a manager i have found people are more productive and much better to get along with. Also my husband kids and mother love this product. Doctor's Best does have the best product by far. By the way, I always get experts to talk to when I need any questions answered. My kind of company. Angie.
