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 definitely notice a difference when I stop taking these, have used this and other brands off and on for years. I find that I feel sort of flat when I take them though, like I'm not sad but also can't feel a range of other emotions as normal. Very odd, but during really hard and stressful times they have probably saved my life. Look into Sam E, lots of brans on this site, found it far more helpful!

The product is great and does what it’s supposed to, but when me and my aunt stopped taking fluoxetine (SSRI) cold-turkey (yes I know we could have tapered off, but the issue is the same across the board), we didn’t fully realise the effects of the excess serotonin. We both started experiencing the effects of serotonin syndrome, which can be life threatening. So do your research before taking this if you plan to supplement an anti-depressant withdrawal. Our plan is to wait a full three months to ensure it is no longer in our system before taking the 5-HTP again. It’s a great product, but do your research: it’s powerful stuff.
