Drivers should use it with caution, as the tablets can cause drowsiness and slow down reaction time. You've probably heard of melatonin . It's a hormone produced by the brain that helps regulate our circadian rhythm, the internal clock that regulates our sleep-wake cycle. The production of melatonin in our body depends on exposure to light; its production increases in the dark and decreases in bright light, such as daylight. So ideally, melatonin levels should naturally increase before bed to help us fall asleep, and then decrease in the morning to make us feel refreshed and alert. However, the bright light emitted by cell phones or computers before bed, or even turning on the bathroom light in the middle of the night, can disrupt our circadian rhythms and make it difficult to fall asleep. Melatonin levels can also decrease with age. That's why we combined melatonin , which has been shown in clinical studies to help people fall asleep and stay asleep, with two other natural elements of the sleep cycle: tryptophan and vitamin B6. Tryptophan is a precursor to melatonin and serotonin. Vitamin B6 is also part of the melatonin production chain: It helps convert tryptophan into melatonin. So, these synergistic ingredients create a formula that can really put us to sleep when we need it most. Tryptophan ( Trp ) is one of the amino acids found in proteins. In addition to protein biosynthesis, about 2 percent of dietary tryptophan is converted to nicotinic acid (niacin, or vitamin B3) in the human liver. It is a very important intermediate from which NAD and NADP, involved in many oxidation-reduction reactions, are then synthesized. Tryptophan is also a precursor to the neurotransmitter serotonin, the circadian rhythm hormone melatonin. Vitamin B-6 (pyridoxine) is important for normal brain development, maintaining the health of the nervous system and the immune system. Vitamin B6 plays an important role in the synthesis of GABA, tryptophan and serotonin, which affect sleep. Vitamin B6 deficiency is associated with symptoms of insomnia and depression. Vitamin B6 helps produce the hormones serotonin and melatonin, which are important for restful sleep and mood. There is a strong link between depression and sleep disorders. Research shows that supplementation with tryptophan and vitamin B6 has a greater effect on reducing night awakenings than melatonin alone. https://pubmed.ncbi.nlm.nih.gov/31621274/
