Why You’ll Love It

The essential amino acid L-tryptophan is the precursor for the synthesis of melatonin and serotonin, a hormone and a neurotransmitter involved with mood and stress response. It helps support relaxation, restful sleep, and a positive outlook. This tryptophan tablet includes vitamin B-6, which is required to convert tryptophan to serotonin. If needed, L-tryptophan is converted to niacin in the body, an important B vitamin. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.

Sleep help

Helps on nights when I can't seem to fall asleep. Sometimes I use this tryptophan and sometimes I use the Source Naturals GABA Calm. I like them both.

I absolutely love this! I live in NYC, so sleeping through the night is sometimes a challenge. This gives me a deep sleep and helps me fall asleep faster.

My doctor recommended taking this before bed for improved sleep. I was buying it at a pharmacy and it cost $10 more a bottle. I was glad to find this on thrive.
