New Roots Herbal L-Tryptophan - This amino acid is pivotal for the production of serotonin, melatonin,
and niacin. Serotonin and melatonin stabilize both mood and sleep patterns. Niacin
regulates digestive function for effective metabolism of proteins, fats, and
carbohydrates. Supplementation with L-tryptophan can also increase levels of
the chemical messengers dopamine and norepinephrine, neurotransmitters that
affect pleasure and alertness.
