Special Order - 5-Hydroxytryptophan [5-HTP] (90 Capsules)Introduction of L tryptophan: L tryptophan is an amino acid essential to human metabolism because it is the metabolic precursor of serotonin (a neurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3).* Other neurotransmitters and central nervous system chemicals, including dopamine, norepinephrine, and beta endorphin, have been shown to increase following oral administration of tryptophan.* Because of its effects on serotonin and

Introduction of L-tryptophan:
L-tryptophan is an amino acid essential to human metabolism because it is the metabolic precursor of serotonin (a neurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3).* Other neurotransmitters and central nervous system chemicals, including dopamine, norepinephrine, and beta-endorphin, have been shown to increase following oral administration of tryptophan.* Because of its effects on serotonin and melatonin production in the brain, L-tryptophan supplementation can benefit mood and can also promote relaxation, a benefit for individuals attempting to get to sleep.*

Introduction of  5-Hydroxytryptophan (5-HTP):
5-Hydroxytryptophan (5-HTP) is the intermediate metabolite produced when the body initiates the process of converting the essential amino acid L-tryptophan to serotonin. Serotonin levels in the body are associated with the regulation of sleep, mood, aggression, appetite, temperature, sexual behavior, and pain sensation.*

Supplementing with 5-HTP to facilitate serotonin production is preferable to supplementing with L-tryptophan because, unlike L-tryptophan, 5-HTP cannot be shunted into niacin or protein production.* Supplementation with 5-HTP bypasses the conversion of L-tryptophan into 5-HTP by the enzyme tryptophan hydroxylase, the rate-limiting step in the synthesis of serotonin and a step that can be inhibited by a number of factors, including stress, insulin resistance, increasing age, and deficiencies of vitamin C, folate, and iron.

Beautiful, luxurious-looking watch.
Color: Grey
Beautiful, luxurious-looking watches. Impeccable craftsmanship. Highly polished glass & reflective hour markers & arms pop with a luxurious shine in the light. Love these watches. So much so I have bought several in different color faces for different occassions. Each is beautiful. Finely detailed minute, hour & second hands are easy to read even in dim light. Outstanding quality for the price. Perfect size looks great on the wrist & keeps accurate time. I have had more compliments of these watches, than much more expensive watches I have.

Cheap not worth the money
Color: Blue
You get what you pay for and most of these cheap watches from China that you get on Amazon aren’t worth the time you spent ordering them off the site. I bought like six of them as gifts and none of them lasted more than a month
