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 husband has suffered from depression for 25 years and the 5-HTP has been the only thing to make any impact. For the first time in years he is smiling and occaisionally able to do things he hasn't done in years. He takes it at a low dosage and it still accomplishes much good for him. I have been suffering from depression with an escalation in the last year to dangereous levels. 5-HTP has had a significant impact. It keeps the despair at bay so that I can still go to work and maintain some level of function. I will be increasing my dose to also address migraine headaches, and/or use when hit with a migraine and hope that it will prove as effective with that dysfunction as well. I highly recommend reading the research on this product. It has provided me the ability to continue on without longing for death every day. I am capable of acting, and thinking, and feeling, beyond the depression and despair which were becoming unmanageable and completely overwhelming prior to taking the 5-HTP. I now buy at a higher quantity for myself. Highly recommend.
