Serotonin is a neurotransmitter in the brain associated with positive moods and restful sleep.1-4 To produce and maintain optimum serotonin levels, your body requires tryptophan, an essential amino acid the body can’t produce.1

In the body, tryptophan has been shown to:

  • improve sleep3,4
  • enhance mood1,2,4
  • modulate stress5

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.
