## Description

L-Tryptophan is an essential amino acid (protein building block) in human nutrition that helps promote healthy sleep. Essential amino acids are not synthesized by the body and must be obtained in the diet.

Review: Great for Depression, Great for Sleep - I switched over from the Now Tryptophan powder because it tasted so .... distasteful. This is pharmaceutical grade and is "Tryptopure" and made from entirely plant-based sources. I have double depression and MTHFR, which interferes with the conversion of trytophan into serotonin, so I take a lot of this to get enough serotonin into my system. But it is a life saver. I like it much better than 5-HTP, which does not seem to have much of an effect for me. If I take a lot, it is a great sleep aid (along with Gaba). For this I usually take 4 capsules / 2 grams or 6 capsules/ 3 grams. I wake up feeling refreshed instead of hung over like I would if I took Ambien. At the beginning of the day, I take about 1 gm (2 capsules) to help me feel happy. Make sure to take it on an empty stomach and away from other amino acids like tyrosine. Gaba is a different kind of amino acid, so I take them together. But the trytophan is a relatively weak amino acid and has to compete against other amino acids to get through the blood brain barrier. Sometimes the other amino acids get through the blood brain barrier and this gets swiped away and brought down to the cell walls to be turned into muscle instead of going into the brain to convert into serotonin/melatonin for good mood and good sleep. I also make sure to take it with other vitamins and minerals that help it convert from trytophan into serotonin, like B complex, Vitamin C and magnesium.
Review: Really helps me sleep - Menopause has really made it hard to sleep the past few years. The L-tryptophan supplement has greatly improved my quality of sleep. I rarely wake up during the night anymore.

### ⭐⭐⭐⭐⭐ Really helps me sleep

Menopause has really made it hard to sleep the past few years. The L-tryptophan supplement has greatly improved my quality of sleep. I rarely wake up during the night anymore.

### ⭐⭐⭐⭐ That’s a pretty good pill, PawPaw!
*by E***A on April 8, 2020*

I add this to my nighttime routine and find it helps complement the melatonin i take. I believe it is a quality product, but I am not in a lab to do tests that could verify any of this. I do believe it has a subtle (desired) effect on my overall serotonin levels, but i cannot confirm that, either. Anything is better than SSRI’s that are similarly unknown to the psychopharmacological community prescribing them: mediocre and conflicting test results and virtually zero expertise re: mechanism of action, side effects, potential risk, or safe prescribing criteria... But that is just my own, non-M.D. personal experience and opinion.
