L-Tryptophan is an amino acid that is converted in the body to serotonin, an important neurotransmitter that supports many functions in the brain and is used to aid sleep. As we age, many find it more difficult to get a good night’s rest and L-Tryptophan can help maintain serotonin levels to support normal sleep.*
