Expiration Date:Expiration Date
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.

Peptides are isolated from whey proteins to deliver amino acids in a soluble and more bioavailable form. As such the amino acids can be directly absorbed and moved into the bloodstream. Tryptophan is the pre-cursor to serotonin, melatonin and niacin. In order to use tryptophan the body also needs sufficient supplies of vitamin B6. It might be sensible when taking tryptophan over the long-term to regularly add some B6. Tryptophan is most affective taken along side some carbohydrate (fruit or orange juice), this is because carbohydrates cause the body to release insulin which in turn helps to utilise tryptophan more easily. Personally when using this product I would say the effect from tryptophan is longer lasting. If I take normal pure l-tryptophan, the effect seems to last two hours after which I might feel worse; and I'm not planning on taking a capsule every two hours. If I take two tables of this at noon for example (500mg tryptophan in total), I feel good for the rest of the day; and even better in the evening. So my personal observation is indeed that this form is better utilized by the body!

Anytime I feel like I'm shifting into my old habit of going to sleep too late I take 2 pills, and in 30-40 minutes I'm gone. It's an amazing supplement. I use it when I feel panicky or sad, about-to-have-a-meltdown type of mood, it doesn't make me sleepy then, but it really really calms me down, especially when taken during the day (1 pill). But I wouldn't suggest taking it if you might have to drive, because it might make you a little bit too relaxed. It helps with anxiety too.
L-Tryptophan - a positive effect

For years I took L-Tryptophan supplements at bedtime to sleep and found them very effective, and then there was the case where L-Tryptophan had been tampered with (just as Tylenol had been) and it was pulled off the market. Always looking for a supplement to help me sleep, I saw this product on iHerb.com and thought I should try it. The price was very reasonable, so I ordered it and have been pleased with what I feel the results are. For now what I am most pleased with is that I stay asleep rather than waking up every hour and a half. Absolutely recommend the product - it is worth trying because there are absolutely no side effects.

May be working in the long term to produce serotonin or melatonin. I guess.
