Life Extension utilizes an essential amino acid that helps the body make and maintain optimal levels of serotonin in its L-Tryptophan supplement. Serotonin, a neurotransmitter in the brain, is known for supporting healthy sleep, mood, and stress response. If you don't receive enough L-tryptophan in your diet from foods like turkey, chicken, bananas, cheese, eggs, milk, chocolate, fish and others, you may want to try supplementing with this essential amino acid.


- A non-GMO, amino acid formula

- 500mg L-tryptophan per capsule

- May support the production of serotonin in the brain

- Seeks to support healthy sleep, mood and stress response

- 90 vegetarian capsules

It is recommended that this supplement be taken with a small amount of carbohydrate (e.g., diluted juice), and separately from amino acids and protein.
