Melatonin, sleep hormone
The melatonin contained in Melatonine B12 is a hormone that you naturally produce at the level of the pineal gland from serotonin. Its concentration fluctuates during the day, punctuated by exposure to light.
It is called "chronobiotic" because it plays a role in the regulation of the internal clock.
EFSA (European Food Safety Authority) confirms its following beneficial effects:
- Melatonin contributes to reduce the amount of time. The beneficial effect is obtained by the consumption of 1 mg of melatonin (1 MELATONINE B12 capsule of Dr. Jacob's®) Before bedtime.
- It also helps Mitigate the effects of time difference. The beneficial effect is obtained by the consumption of at least 0.5 mg just before bedtime the first day of the trip and the few days following the day of arrival at destination.
✓ Supports the quality of sleep.
✓ Recovery in case of time offset or during changes in summer and winter time.

- aid for the normal operation of the the nervous system and the system immune,
- support of normal psychological functions (relaxation),
- participates in the normal metabolism of the homocysteine.
Sleep and melatonin

The synthesis of melatonin is inhibited in the presence of light and stimulated when it is dark. Its peak is between 2 and 4 hours of the morning, while it is at its lowest level during the day.
From 50 years old, the concentration of melatonin decreases naturally and is correlated with the lowest sleep quality observed in older people.
In addition, people doing nocturnal work (nurses, workers ...), frequent travelers submitted to hourly offsets have a lowest quality of sleep following a discrepancy between the pace of life and the environment.
