Melatonin is ideal for sleep and normalizing circadian rhythm*
-synthesis of melatonin can be decreased by the aging process
-helps regulate the sleep-wake cycle*

Melatonin,the primary hormone of the pineal gland,acts as a powerful "chronobiotic," helping to maintain normal circadian rhythms.* In individuals having difficulty sleeping or with altered circadian rhythms,such as occur in jet lag and night shift work,supplementation with melatonin can help provide the resynchronization of those cycles,at amounts ranging from 0.3-8.0 mg.* Synthesis of melatonin from the amino acid tryptophan can be decreased by the aging process. Melatonin is a potent antioxidant.* Adequate melatonin levels have been reported to be a positive factor cardiovascular,neuroendocrine,and bone health.*
The timing of melatonin supplementation appears to be an important factor,with the most effective protocol being a diurnal cycle similar to the physiological rhythm of melatonin secretion,which is generally to take it once in the evening before going to bed.
