Vitamin B6 (Pyridoxal 5-phosphate) is the active form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP (a naturally occurring amino acid in the body) to serotonin. Serotonin is one of the most important brain chemicals, or neurotransmitters, for regulating the sleep/wake cycle and promoting deep and sustained sleep. Vitamin B6 deficiency has been linked to irritability, emotional disturbances, confusion and disturbed sleep. Studies show that vitamin B6 positively impacts aspects of sleep and is essential for promoting and maintaining a good mood.*

Magnesium is a mineral involved in over 300 enzyme-related biochemical processes and influences sleep in a variety of ways. Magnesium helps the body maintain healthy levels of GABA (gamma aminobutyric acid), a naturally occurring amino acid that works as a neurotransmitter in your brain and, in part, can help calm the body and mind while preparing for sleep. Those who are deficient in magnesium are more likely to have nocturnal awakenings, less time spent in stage 5 REM sleep, and poor sleep quality. On the other hand, those taking dietary magnesium supplements are more likely to experience better sleep efficiency, the ability to fall asleep faster, and the ability to reduce cortisol (stress hormone) levels. *

Glycine is an amino acid that elevates serotonin and improves sleep quality. Studies suggest it helps you fall asleep more quickly, increases sleep efficiency, improves sleep quality and promotes bouncing back to healthy sleep cycles after a period of disrupted sleep.*

Valerian [root] extract may reduce the amount of time it takes to fall asleep and helps you sleep better. According to multiple clinical studies, it is commonly used to induce and improve sleep, and may significantly improve sleep quality. Valerian seems to be most effective for people who have trouble falling asleep and who consider themselves to be poor sleepers, and has had good results for people who wake up during the night.*

Zizyphus Jujube extract has been used for sleep issues in traditional Chinese medicine for centuries and is known to benefit our brain by calming down the mind and improving quality of sleep.*

Hops extract has natural sedative effects and can increase sleep time. Hops has also been shown to reinforce the body's daily bio rhythms of rest and activity.*

Melatonin is a hormone that helps regulate our circadian rhythm, which synchronizes our sleep-wake cycle, and is one of the most popular supplements used by people who have trouble falling asleep.*
