The essential amino acid L-tryptophan helps support relaxation, restful sleep, and a positive outlook. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. This tryptophan includes the activated coenzyme form of vitamin B-6, called P-5-P, that is required to convert tryptophan to serotonin. L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, L-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.
1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 tablets before bed.
Dibasic calcium phosphate, stearic acid, modified cellulose gum, and silica.

I have tried varieties of L-Tryptophan. Even one compounded by a pharmacist. This version with the Coenzyme B-6 is the most remarkable. I feel better quickly and sleep very well at night. It helps with daily stress and is perfectly safe. Eliminates many cravings for sugar and caffeine. A great investment in my health. Wouldn't be without it.
The inclusion of B6 as p5p was a good choice in conjunction with tryptophan. The Dr. Best formula includes B3 as niacinamide (which is a known soporific agent), but having added my own niacinamide, I cannot perceive any difference. Melatonin is synthesized AFTER serotonin. The synthesis of serotonin (and other neurotransmitters) is catalyzed by a B6-dependent enzyme. Furthermore, B6 is required to manufacture Niacin from tryptophan. Thus a reason one might choose tryptophan over melatonin is NOT to skip any intermediary steps (there are a few studies showing that direct melatonin supplementation reduces levels of intermediary products). I use low-dose melatonin anyway (Same brand, sustained release) because sleep is scarce.

I took just one the first time I opened my new bottle and didn't notice any difference in my sleep pattern. So, it sat om my nightstand next to my other medications and supplements for a few weeks. Then 2 days ago, I read the back label once, then again, noticing I could be taking them MORE than just at bedtime. So, I began taking one at bedtime and for 2 days in a row I slept through the night. And today I took one in the morning along with my pain med and anxiety med and did a few things and started to feel a difference in my mood. I went to my chiropratic appointment and he was able to do a wonderful manipulation. And I began to really feel good. I plan to give this a chance by taking just the 2 a day and see how I continue doing. Hopefully I can stop taking my anxiety med at some point after speaking with my Primary doctor who I advised ahead of time that I had purchased the L-Tryptophan. Right now I'm ready for my 2nd dose. Quite the unexpected results.

This seems to do the job as described. I sometimes need a little something for sleep.

I take two of these before bed and i find I have a more restful sleep and don't wake up during the night. I like the Source Naturals brand, I have tried a few different supplements from them and I find they've worked better than other brands.
