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.

I was using l-tryptophan (3 grams a day) and it did not help my depression/anxiety. When I switched to this 5-htp it was amazing. I started at 100mg, 3X a day along with 1000 mg L-tyrosine ( 3X day) for one week. Then I went to 5 -htp 100 mg, 4X a day with 1000mg tyrosine, 3X day and withing 3 days at this dosage I felt like myself again and do not feel depressed at ALL! Love that it is enteric coated so no stomach irritation. Take on an empty stomach. Don't forget to add a coenzymated b complex supplement at breakfast and vitamin C. And add extra folate in the form of methylfolate (Solgar brand) as it helps make serotonin, norepinephrine and dopamie.

I have been using it for the past 3 weeks and i have to say that within several days i have noticed a positive change in my mood and happiness. I was really glad to find this one helpful, but unfortunately i think i'll stop taking it since it makes be bloating. My belly bloats loke a balloon. At first i didn't understand why is it happening , but only later i realised it was because of this supplement.

I've tried a few brands and this one is the best. I usually take 50 mg but even cut in half, therefore making its enteric coating redundant, this tablet doesn't hurt my stomach. It really is an excellent way to keep your serotonin levels healthy. But don't take too many as cortisol rises with serotonin, so if you push the boundaries you'll end up sleepy and stressed (ie heart pounding, body under stress) at the same time! That's what happens to me if I take more than I need.

After 7 years taking antidepressants, which made me feel like a zombie, constantly tired most of the time, to many side effects from the meds, i came cross a video on youtube, john gray 5htp watch?v=wltfQ4qOA8Q, this is an excellent product for mood stabilization, sleep, suppressing appetite. This is the precursor to serotonin...

I was using the "now" brand of 5-htp with great success but always hated the nausea ide get with it afterwards, after switching to this brand that problem is fixed.

My husband and I having been taking 100mg 5-HTP for a few months now and not only has it helped us come off antidepressants without tumbling into despair it has been a wonderful alternative to being on them at all. The enteric coated tabs prevent any tummy troubles and we've both found taking 100mg at bedtime gives us a good night sleep with no 'hangover' in the morning. When we took them during the day we did feel very sleepy - if anxiety or hyper-arousal was an issue this might be useful but we find it hard to get going at the best of times! When "Life" gets a bit tough - we up the dose with the 50mg tabs which seems to flatten out the bumps quite well - some bumps are unflattenable but at least we've got the goods to face it head on and not be crushed by the thought of tackling the big stuff. We both found on anti-depressants that we were in a 'chemical straight-jacket' and far too many 'whatevers' were being mumbled and way too many things went through to the keeper that should of been addressed - we're now in the process of 'mopping up' from a lot of that non-decision making.... I will NEVER go back on anti-depressants again now that I have found a reliable and real alternative. If you're at the point of knowing you need help but aren't really wanting to start on the antidepressant merry-go-round DEFINTELY give 5-HTP a fair go, I wish I'd known about it before I filled the Cymbalta script!!!
