Pure Rest Difference
USANA's Pure Rest is made from an exceptionally pure source of melatonin
Most researchers agree that getting enough sleep is equally important to long-term health as eating a healthy diet and exercising regularly. Unfortunately, millions of individuals suffer from occasional sleeplessness—the incidence of which increases with age. Other lifestyle factors, such as stress or alcohol consumption, can contribute to poor sleep as well.
Poor sleep results in tiredness, poor concentration, reduced quality of life, compromised immune function, and an increased risk of morbidity and mortality. Sleep deprivation has also been linked with increases in markers of oxidative stress and decreases in levels of antioxidant enzymes (e.g., SOD, glutathione reductase, etc.) in the brain, liver, and heart.
Melatonin is a naturally occurring hormone synthesized in the brain that regulates normal sleep and wake cycles. Melatonin levels naturally start to rise in the evening and remain elevated for most of the night, signaling to our body that it is time to sleep. As melatonin levels rise we become less alert and feel drowsy. USANA's Pure Rest supplement supports the natural increase of melatonin production at night. They are not sleeping pills. When taken at bedtime, oral Pure Rest supplements support the body's natural circadian rhythms and have been clinically proven to help promote sleep, which restores the body after daily exposure to free radicals and general wear and tear.
 
Antioxidant Support
Sleep is restorative with respect to oxidative stress, and melatonin, by promoting sleep and inactivity, allows the body's natural antioxidant defences to overcome the oxidative stress that accumulated during the day's activity.
 
Melatonin and Immune Function
Adequate amounts of sleep are necessary for healthy immune function. As a compound that promotes sleep, melatonin may help in keeping the immune system functioning normally.
