The Many Benefits of L-Tryptophan

L-Tryptophan is an essential amino acid that the body cannot produce on its own. It must be obtained through diet or supplements. L-Tryptophan is known for its ability to encourage a positive mood and promote restful sleep. It is also critical for the production of serotonin and melatonin. Additionally, L-Tryptophan supports proper immune system function. Every lot of NOW L-Tryptophan goes through rigorous testing to ensure it is free of Peak E and microbial contamination.

Here are some of the many benefits of L-Tryptophan:

Mood Support*

L-Tryptophan has long been associated with mood support.* A 2009 study published in the Journal of Affective Disorders found that L-tryptophan was effective in reducing symptoms of mild depression and anxiety in adults.* Furthermore, a 2008 study published in the journal Nutritional Neuroscience found that supplementing with L-tryptophan may help to reduce stress and negative moods.*

Sleep Support*

In addition to its mood-supporting benefits, L-tryptophan can also promote restful sleep.* A 2007 study published in the journal Biological Psychiatry found that subjects who took L-tryptophan before bed reported feeling more rested upon waking compared to subjects who did not take the supplement.*

Immune System Function*

The immune system is responsible for fighting off foreign invaders like bacteria and viruses. Therefore, it's important to keep it functioning properly. Some research suggests that L-tryptophan may help to support proper immune system function.* A 2006 study published in the journal Brain, Behavior, and Immunity found that participants who took 5 grams of L-tryptophan per day for four weeks had a decrease in proinflammatory cytokines—molecules associated with inflammation—compared to those who did not take the supplement.*
