      Breaking it down

      Below we've broken down the main functions of our L-Tryptophan and the benefits it can provide.

      Restless leg symptoms can be caused by a lack of dopamine. L-tryptophan can be converted to serotonin in the body which then can be converted to dopamine. This may help relieve the irritating symptoms of restless legs.

      L-tryptophan can be converted in the body to melatonin by the pineal gland which helps regulate wake and sleep cycles to promote restful sleep.

      What the research says

      L-tryptophan has a large impact as a neuromodulator and is involved with a number of central nervous system functions including mood, pain, sleep and motor behavior. Studies have shown a decrease in restless leg syndrome symptoms with continued use of L-Tryptophan.
