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.
5-HTP (L-5-Hydroxytryptophan) is an intermediate in the natural conversion of the essential amino acid, tryptophan, to serotonin. Clinical studies have shown that 5-HTP increases the amount and availability of serotonin produced by the body. Increased brain serotonin levels may produce positive effects on emotional well-being, appetite regulation, melatonin production and maintaining a healthy sleep cycle. Source Naturals 5-HTP is naturally derived from the seeds of the African plant Griffonia simplicifolia.

This really works to reduce appetite, without the side effects of sleepiness and constipation. An excellent company - their mint-flavored sub-lingual melatonin is the best of its kind.

I can not really say whether is working or not, currently taking it everyday. I could say that I sleep a bit well.

Too early to say, but I think it has improved my sleep. My sister is less depressive on this, and that's great! :) For myself, I prefer the Holy Basil from New Chapter (it makes me calm and certainly improves my sleep and overall feeling).
