Tryptophan is an essential amino acid that produces a mood-enhancing neurotransmitter called serotonin. The body can also transform tryptophan into other helpful compounds within the body, like niacin and melatonin, which are also key ingredients for healthy sleep. When the body is deficient in tryptophan, therefore, it may also be deficient in several other, essential chemicals. This deficiency can inhibit sleep and trigger numerous physical and/or mental disorders. Tryptophan deficiencies are associated with depression, insomnia, premenstrual syndrome, schizophrenia, attention deficit disorders and autism-spectrum disorders.
Adequate levels of tryptophan are essential for biochemical balance of the brain. Pure Essentials Sleep Enhance uses only the highest-quality, pharmaceutical-grade L- tryptophan, plus key transport-enhancer nutrients in their most bioavailable and natural forms, for the most effective results. In contrast, many sleep supplements use 5-HTP, a metabolite of tryptophan.
Additional, all-active nutrients that function synergistically with L-tryptophan include vitamins B2 (riboflavin 5-phosphate) and B6 (pyridoxal 5-phosphate), which are essential co-factors that maximize the absorption of L-tryptophan and strengthen its sleep- and mood-enhancing properties.
