The research report 1999 published in the journal Toxicology Research published by the American Chemical Society in May reminds users that the melatonin content of normal people is very low. If excessive melatonin is absorbed through the intake of healthy food,
On the contrary, it will produce "derived free radicals" that harm the human body, affect behavior and cause unexpected health problems. Germany: Authoritative experiments have confirmed that melatonin inhibits gonadal development. Among European countries, Germany has the strictest control over melatonin. So far, because the function of melatonin is not clear, it is not allowed to be registered as a drug in Germany. Germany is the first country to study pineal gland, melatonin and reproductive function simultaneously. 1998, a boy was found to have precocious puberty by a German doctor. At the same time, the tumor of the boy's pineal gland was found, and the normal tissue had been destroyed. It is also because of the destruction of the pineal gland that boys have precocious puberty. So the doctor first put forward the concept that the pineal gland inhibits gonadal development. Since then, people have also proved the role of melatonin secreted by the pineal gland through animal experiments. Injecting melatonin into animals will cause many anti-reproductive phenomena, such as delaying the sexual maturity of immature animals and inhibiting the spontaneous ovulation and estrus response of animals. Injecting melatonin into rabbits not only makes the bisexual reproductive organs smaller and shorter than normal, but also makes the follicles in the ovaries of female rabbits degenerate, the uterine muscles decrease and the sperm cells in the seminiferous tubules of male rabbits degenerate. If the injection lasts for 6 months, both men and women will lose their reproductive ability. Therefore, some researchers have concluded that melatonin has obvious inhibitory effect on reproductive function. Even Dr. Utermann, the patent holder of melatonin products, fully agrees with this point.
Britain: Experiments sponsored by the Ministry of National Defense confirmed that melatonin is harmful to human body, instead of treating insomnia. At present, in Britain, because of its controversial efficacy, melatonin is strictly controlled as a prescription drug and cannot be obtained in pharmacies. The first scholar in the world who corrected the time difference with melatonin was Dr. Allende from the University of Surrey. According to a study sponsored by the British Ministry of Defence and presided over by Professor Middleton of the University of Surrey, melatonin can not only cure insomnia, but also cause "intermittent sleep". The British Ministry of Defence stressed that sometimes melatonin not only does not help to improve insomnia, but is harmful, which is completely contrary to the "baby-like sleep" emphasized in the past. Animal experiments by researcher Aaron De and human experiments by al show that sleep is caused by the vibration of day and night. If you take melatonin at night, the body will send out a strong sleep signal, break the circadian rhythm, destroy the circadian rhythm, and make the vibration no longer happen. When the rhythm of nature disappears, this person's sleep will be disordered. Therefore, the efficacy of melatonin has yet to be confirmed.
The drug seller said that you also believe that melatonin is mainly melatonin, but it is best to eat vitamin C garlic every day at least harmless.
