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.

After taking 100mg of 5-HTP for several weeks, I'm pleasantly surprised by the results. My sleep is much improved; Within about an hour of taking a 100mg capsule of 5-HTP I'm relaxed, sleepy and ready for bed but, thankfully, it's not the same feeling that a person gets after taking a prescription sleep aid. In my waking time, I find that I have little craving for junky, carbohydrate-laden foods. I'm thankful especially that I no longer have a late-night hunger for sugary junk food. My mood hasn't much changed, but depression — of the type caused by brain chemistry — can be a result of a defecit of the neurotransmitters Dopamine, Norepinephrine, and Serotonin. Since 5-HTP works by stimulating the human body's own production of Serotonin, I think that a person must have depressed levels of Serotonin in order for this product to make much difference in their overall quality of life, since depression can involve other neurotransmitters. To those who already take prescription anti-depressants: Please be careful! Consult with your medical professional, since 5-HTP — together with SSRIs — can create dangerous levels of Serotonin in the brain and cause Serotonin Syndrome.

I took my first pill as directed, before bed. I noticed I was sleepy, and I slept well, and woke feeling good. I really noticed t, so I spent time on here reading a lot of the reviews. Then I decided maybe I'll take one in the morning as well. But half hour later I was lazy, tired. So then I decided, nope. I'll just see how it effects me taking it at night because I don't want to feel sleepy during the day. So I've been taking 1 pill before bed for a couple weeks. And I kid you not, I sleep better and wake up better, but best of all, my mood has completely changed from being fatigued, mildly depressed, lazy, hard to get outta bed...to feeling good every day since I stared taking these. I'm happier, less things bother me, I don't know how to explain it, but I spent a lot more time in bed alone then I do now! Who knows, it could be the sunshine, summer is here now. But I believe it has worked for what I wanted it for and that was to improve my mood. And I will keep taking one a night before bed as long as it keeps working. Also, as an added bonus...less hangovers! Haha. Seriously though, any night that I've drank wine...even late nights, I get up feeling good the next day. So 5 stars from me!
