HealthWise® L-Tryptophan is 100% pure pharmaceutical grade amino acid. This essential amino acid is found in all animal proteins and is often lacking in a vegan diet.
L-Tryptophan and the conversion to 5-HTP are known precursors to enhance the neurotransmitter Serotonin, manufactured in the brain and GI tract. L-Tryptophan absorption can be boosted by supplementation with B group vitamins.
Tryptophan is an essential amino acid. It is the precursor to 5-hydroxytryptophan (5-HTP) which is the direct precursor to serotonin. Serotonin is important for mood and sleep; when it is deficient, this can lead to anxiety, depression, insomnia and various other neuropsychological conditions. L-Tryptophan works in about 50% of insomnia cases.
Tryptophan is the precursor for vitamin B3 in the form of nicotinamide adenine dinucleotide (NAD). Only about 1/60th of the tryptophan in the body is actually converted to NAD.
