Studies have shown that having a healthy circadian rhythm—and thus adequate levels of melatonin in the body—provides a healthy sleep-wake cycle.
Melatonin, a hormone released by the pineal gland at night, is most well-known for its role in eliciting sleep and helping balance the internal clock, or circadian rhythm.
New research finds that in addition to the sleep benefits of melatonin, it also is responsible for many different physiological processes in the body including healthy fertility and fetal development, thus playing a large part in men and women’s fertility.
To benefit from Melatonin it should stay in your body as long as possible at night yet not make you tired during the day. Regular fast release Melatonin raises the Melatonin levels immediately, however, the half life is only 30 minutes which means half of the amount taken will be ineffective after half an hour. Slow release formulas increase Melatonin levels over a period of time, the downside, they create morning grogginess,
Therefore a pulsatile Melatonin formulation which raises the serum levels immediately, stay in the body over a period of time and then decrease fast is the optimal solution.
