L-Tryptophan 220 mg

ʟ-tryptophan is the amino acid precursor to the synthesis of serotonin and melatonin, which promote good mood and healthy sleep cycles.

ʟ-tryptophan is an essential amino acid - meaning the body cannot synthesize it and must acquire it through the diet. This amino acid is essential for the production of serotonin, melatonin and niacin: serotonin and melatonin stabilize mood and sleep cycles; niacin regulates digestive function for optimal protein, lipid and carbohydrate metabolism.

Supplementation with ʟ-tryptophan can also increase levels of dopamine and norepinephrine, neurotransmitter chemical messengers that act on pleasure and alertness. L-Tryptophan from New Roots Herbal is an excellent choice for supplementing levels of this essential amino acid, which is depleted with age and can prove useful against insomnia, as well as for improving mood and general well-being.
