Does it’s job for me
I have major sleep issues. I use L-Tryptophan coupled with Magnesium glycinate and I find I don’t have so many waking episodes at night. I feel I also have a more restful sleep. It has been worth my $$ to get better sleep.

Very helpful --find the right dose for you
This has helped me a lot. Tryptophan is a precursor for both melatonin and serotonin. Is being studied and should be studied more for anxiety depression especially postpartum. PSA: find your right dose! I started out taking one capsule twice a day just to get a feel. When I took two capsules several times a day (thinking it would help me sleep) I think I had excess serotonin which felt like kind of like too much cortisol, increased anxiety. So this stuff is good but find your balance with it to benefit.

Only one that works!
First of all, the reviewer who called this a scam clearly doesn't understand FDA regulations or patented formulations of supplements. "Triptopure" IS L-tryptophan. And the FDA doesn't directly regulate ANY supplements, but they have the regulatory power to stop the production of unsafe ingredients in supplements, which they do all the time. Now my review... This brand of L-tryptophan is so far the ONLY one that helps me sleep. I felt the need to deduct one star though because of the price. I have even tried cheaper brands made with "Triptopure", and adding B6 (as this brand's ingredient list indicates), but they still weren't as effective as Pure Encapsulations. My insomnia is due to perimenopause and I have to combine this with melatonin, otherwise I can't sleep through a full night. I'll take this for the rest of my life if I have to, however, as it's a safer option than over-the-counter meds and prescriptions.

Excellent quality Tryptophan supplement.
Pure Encapsulations is one of the best brands on the market. For years, it has been available by prescription. Thankfully, they offer it to the general public. Excellent quality ingredients. Twenty minutes before retiring provides an easy pathway to sleep. There are no after-effects when waking up the following day.
