- Helps support relaxation, restful sleep, and positive mood
- Plays a part in the synthesis of both melatonin and serotonin
- Supports immune functions
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 stress response and sleep/wake cycles. l-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that promote 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.

Free of additives
I take different amino acids and, whenever I find one that is a pure powder, I use it instead of capsules. I take a lot of supplements and do not want to be ingesting all the additives. Be aware that, because this is only the powder (no sweetener added), it is rather bitter, so if you only like sweet tasting or good tasting supplements, you may want to add this to something that masks the taste. I feel tryptophan helps me sleep.
