Melatonin secretion decreases during aging. Reduced melatonin levels are also observed in various diseases, such as types of dementia, some mood disorders, severe pain, cancer, and diabetes type 2. Melatonin dysfunction is frequently related to deviations in amplitudes, phasing, and coupling of circadian rhythms.
The synthesis and release of melatonin are stimulated by darkness, melatonin is the "chemical expression of darkness" and inhibited by light [4]. Photic information from the retina is transmitted to the pineal gland through the suprachiasmatic nucleus of the hypothalamus (SCN) and the sympathetic nervous system [5].
Fish is a better source of melatonin than other meats. The best options are oily fish like salmon and sardines, which also provide valuable omega-3 fatty acids. Most nuts have a good amount of melatonin. Pistachios and almonds are among the highest.

The melatonin average concentration was 6.98 pg/mL in the cows' milk, 4.71 pg/mL in the BTM, and 5.62 pg/mL in the UHT milk. In the night milk, the melatonin concentration averaged 14.87 pg/mL, whereas it was 6.98 pg/mL in the total daily milk.
A combination of both methods — timed application of bright light in the morning and a dose of melatonin in the evening — seems to be the most effective therapy for treating melatonin rhythm disturbances. Melatonin has not only been shown to advance sleep time, but to increase sleep duration as well.
But, although the hormone's plasma levels at nighttime remain at least an order of magnitude higher than at daytime throughout the life span, its absolute concentrations undergo a continuing decline after peaking at ages 2–5 yr (2–4).
