Life Extension L-Tryptophan, 500mg, 90 Vcaps


Serotonin  - is a neurotransmitter in the brain associated with positive moods and restful sleep.

To produce and maintain optimum serotonin levels, your body requires tryptophan, an essential amino acid the body can’t produce.39

In the body, tryptophan has been shown to:

  • Improve sleep

  • Enhance mood

  • Modulate stress

The basis for this formula is premium L-tryptophan, which has undergone significantly more rigorous manufacturing processes than regular tryptophan material to assure the highest purity and safety.
