Description

L-Tryptophan
Mood, Relaxation, Sleep*
Dietary Supplement

The essential amino acid L-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and street response and sleep/wake cycles. 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.*



HYPOALLERGENIC: contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

L-Tryptophan
I take one supplement in the morning and one at night. It helps me sleep well at night and helps my mood during the day. It worked well for me the first night I took it. Sometimes it can leave a bad aftertaste, but I found if I drink enough water this doesn't happen.

I take one capsule in the morning and one at night. It helps me sleep well and keeps my mood balanced throughout the day. It worked for me the first night I used it. Sometimes it can leave an aftertaste, but I have found if I drink more water that usually doesn't happen.

It actually works as a sleep aid!
This actually works as a sleep aid, promoting both intial sleep (falling asleep) and mainting sleep throught the night. It doesn't leave you groggy in the morning, either. No side effects I can find and it is safer than pure 5-HTP which can cause serotonin syndrome in large dosages. Great product!
