Doctors Best

Best L-Tryptophan products contain Ajinomoto TryptoPure™. Tryptophan is an essential amino acid readily converted by the body to the neurotransmitter serotonin. Able to cross the blood-brain barrier, L-tryptophan is altered by enzymes to first form the intermediate amino acid 5-HTP and then serotonin. It is also the metabolic precursor to melatonin and to the B vitamin niacin. Supplementing the diet with pure L-tryptophan like TryptoPure™, found in Doctor’s Best L-Tryptophan products, can improve sleep and enhance mood, and may also be beneficial in reducing carbohydrate cravings.

Doctor’s Best L-Tryptophan Enhanced additionally includes the active form of vitamin B6 and the B-vitamin niacin (as niacinamide) as cofactors for the enhanced utilization of L-tryptophan. Vitamin B6 is an essential cofactor in the conversion of tryptophan, while niacinamide plays an important role in allowing our body to properly utilize this essential amino acid. Clinical observation suggests that supplementing with Vitamin B6 and niacinamide in conjunction with L-tryptophan enhances the ability of tryptophan to support healthy sleep.
Suggested Use: Take 1 or 2 capsules daily or as directed by a health practitioner. For optimum absorption, take separately from protein-containing foods and dietary supplements containing protein or amino acids.
