L-Tryptophan - Product Image
L-Tryptophan

L-Tryptophan by Thorne Research - Mood & Sleep

 

L-Tryptophan

Precursor to serotonin, melatonin, and niacin

  • amino acid essential for brain serotonin and melatonin production*
  • promotes relaxation, sleep, and good mood*
  • contains no preservatives, magnesium stearate, or other lubricants and diluents
  • made without flowing agents that can inhibit its bioavailability

Product Information

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.

"There are several Total Supplements' products that I rely on to keep me healthy and functioning. I usually try to order them in advance but sometimes forget or have to wait to order. I am and can always be confident that they will arrive very quickly, much quicker than any other product that I order (that aren't even of the same quality). I have been a customer for well over 5 years and have confidence in saying that they will get you your product fast."
