  • These L-Tryptophan 500 mg 120 Tablets from Source Naturals may support sleep‚ mood‚ and relaxation.

    L-tryptophan is an amino acid‚ a protein building block that can be found in proteins. L-tryptophan is called an essential amino acid because the body can’t make it and it must be acquired from food.

    Getting a good amount of sleep is essential for staying alert and healthy. These days‚ everyone has busy schedules and related stress‚ which affects sleep. The L-Tryptophan in this supplement from Source Naturals gets converted to 5-hyrdoxytryptophan (5-HTP) and then to serotonin and melatonin. Serotonin and melatonin are known for their impact on mood and stress response and sleep-wake cycles.

    Another specialty of this supplement from Source Naturals is that it might also support the immune system‚ being the body’s precursor to the kynurenines‚ which regulate immunity.

    Works for me!

    This is a very high quality L-Tryptophan by Source Naturals that I would recommend to anyone who has trouble sleeping or would like to stop taking prescription/OTC sleep aids. No hangover feeling and works throughout the night. Although a liquid version may work faster, I usually will wake-up a few hours later.


      It works and has consistently been high quality!



    I would recommend this item to a friend.
