View this orderThe 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.
Read the entire label and follow the directions carefully prior to use.
Take one (1) capsule 1 to 3 times daily on an empty stomach, or as recommended by a healthcare practitioner. For maximum absorption, take with a small amount of carbohydrate, such as diluted juice. Best if taken separately from protein and amino acids.
