Melatonin releases from the pineal gland, reaching its peak at night to help maintain tissues in a youthful state of health. Secretion of melatonin declines significantly with age, as the pineal gland becomes calcified.

Melatonin keeps our circadian cycle in tune as it communicates with the body’s cells. Not only does this hormone work to maintain cell health, it appears to regulate a system of self-repair and regeneration. When this hard-working hormone is diminished, our biological functions are impaired.

Many people use melatonin to help improve sleep. Some research has found that melatonin increases the speed of falling asleep and adds to the quality of sleep in about 60% of people who use it.
