NusaPureL-Tryptophan 1500mg 200 Vegetarian Caps (Non-GMO, Vegan) Bioperine

I’ve been taking this for a year now. Can really feel the progressive benefits of the product. I’m a lot calmer and upbeat

It took a couple nights but I am sleeping better. I used this back in the 80's before it was take off the market for sleep. I've used many different over the years both RX & natural & this is - so far - the best I've used.

Seem to be good quality supplements

This product helps me to fall sleep and for that I recommend it highly. I would have given it a higher score, accept that the gel caps get stuck in your esophagus and stick there. They are fine after a few big swallows of water. That isn't that big of a deal for me, but if you have problems with swallowing meds, it may be an issue. Also, just to mention, for me at least, they just help you doze off, but not maintain sleep. I still like the product despite what I have mentioned.

I've been using the other name brand sleep aid (similar ingredient but with "proprietary blend" stuff as well). Because it is expensive I thought to try straight Tryptophan. The price on this is great, and I notice the same, if not better sleep. I love this natural alternative - as melatonin straight does nothing for me, and the pharmaceutical sleep aids knock me out for the next day. Good product, great price.

I've been experimenting with this to help me sleep, and am ready to conclude, it's helping. My sleep is definitely deeper and I can go back to sleep if and when I wake up in the middle of the night. I've always managed to get by on about 5-6 hours of sleep, as long as I get a 15 min combat nap during the day, but my schedule doesn't always allow for that nap. I don't need that nap with this tryptophan. For dosing, I weigh 167 pounds; taking 3 of these every other night seems to work best. If I take it every night, it seems to build up in my system over 5-7 days, then I'm groggy in the morning.Tryptophan is a pre-cursor molecule for serotonin, "the happy hormone"... so in addition to better sleep, there's clinical trials evidence that tryptophan can boost mood, and also boost memory and attention span.

I was looking for a 1500mg pill/capsule... instead got a bottle of 500mg pills with three per dose to make 1500. I hate taking pills, was hoping to take fewer.

I was so afraid of straying from my regular brand of L-Tryptophan, but I had to when they were out of stock. But I'm so glad I tried this brand. The capsules are easy to take (3 per serving) and they start to make me sleepy in about 45 minutes. And it's just a nice, natural sleepiness that allows you to calm down and fall asleep in a gentle way. Not like the sledge-hammer sleep you get with a prescription pill, with the inevitable hangover that follows. This is a good choice for an evening calmer-downer, with no hangover the next day at all.
