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.

Supplementing with L-tryptophan allows the body to use it where it is needed most - for protein synthesis‚ niacin formation‚ or as a serotonin/melatonin precursor. For optimal L-tryptophan absorption and transport across the blood-brain barrier‚ it is recommended to take L-tryptophan with a dietary carbohydrate.

L-Tryptophan is an effective supplement for those who need help falling and staying asleep. Pureformulas.com had L-Tryptophan for the going price but with the coupon, you can save.
Natural way to help you fall asleep and stay asleep. Not habit forming.

My doctor told me to try L-Tryptophan to help me sleep. I was taking anti anxiety medicine to help me sleep and wanted to get off of it. L-Tryptophan helped me immediately and I sleep very soundly and no longer have a need for my prescription anti anxiety medication. I would highly recommend trying L-Tryptophan. I will definitely order L-Tryptophan again!!
I have no trouble waking up in the morning and do not feel groggy the next day

L-Tryptophan was just ok for me. It did help me get to sleep, but I would still wake up during the night. I will keep looking for something stronger. However, if you are not looking to use L-Tryptophan as a sleeping pill, than it does do a good job at calming you and relaxing you.
calms you & relaxes you
did not help me stay asleep
