Melatonin is secreted in the human brain in the pineal gland and is responsible for regulation of the body's biological of the body (1). The melatonin production in our body is strongly dependent on our living conditions and is mainly influenced above all by light. In daylight, the pineal gland produces the neurotransmitter serotonin. At night, however, the production of serotonin is stopped and melatonin is produced instead (2). The production of melatonin varies depending on the amount of light to which we areto which one is exposed. More melatonin is produced at night than during the day, and the body produces more melatonin in a completely darkened room than in a semi-dark room (3). Especially in big cities, brightness and the light pollution that comes with it is a steadily growing problem.. This can sometimes lead to the fact that melatonin production in the brain cannot take place without restrictions (4). Stress, disease, and aging are also factors that can affect melatonin levels (1,5). A deficiency of the hormone has been shown in studies to lead to insomnia (6). (6). Insomnia and irregular sleep habits are associated with a a variety of health problems and premature aging (1,7). There are populations that are often prone to impaired production of melatonin. Studies have shown that especially older people produce less melatonin on average (8). (8). The same is true for people who work shift work work or who regularly have to deal with jet have to fight. Here, too, a study showed that the regular intake of melatonin helped the subjects (9). Since melatonin can be supplied externally, it is finding increasing increasingly popular in the form of dietary supplements.. The intake of melatonin is considered to be an effective way to improve overall sleep quality and to maintain maintain a regular sleep schedule (10). (10). Subjects in one study reported a calmer and deeper sleep (11).

In addition to the regulating effect on sleep, melatonin also has numerous other numerous other positive effects. The hormone has a strong antioxidant effect (8,12). Antioxidants such as melatonin work by counteracting oxidative stress in the body. Oxidative stress is a result of the production of so-called free radicals. These are produced during normal metabolic processes, as well as by various environmental factors. Metabolism also appears to be affected by melatonin. While studies have not shown a correlation between the hormone and lean body mass. However, melatonin did help in one study, prevent the body from putting on extra fat (13). (13). Regular intake of the vitamin has also been shown to have a positive effect on stomach health in scientific studies. positively on the stomach health (14).

In summary, melatonin is a really important hormone in the human body whose importance is directly related to sleep. Without a normal night sleep, many functions of the human body can not run optimally (15). Melatonin from GN Laboratories - Health Line can help to ensure that the Melatonin levels reach an optimal level.. So nothing stands in the way of sleep and regeneration.
