What is the main component of melatonin?

Melatonin is the main component of melatonin, and its English name is melatonin. It is a hormone secreted by the pineal gland at the top of thalamus. Why is it called melatonin? Because it can make the skin of amphibians such as frogs fade, it has no such function for mammals. The pineal gland is very sensitive to light, and melatonin secretion decreases during the day and increases at night. The maximum secretion period of melatonin in human body is in childhood. Around the age of seven, the pineal gland begins to calcify, melatonin secretion decreases, and then people begin to enter adolescence. Pathological changes in the pineal gland can lead to precocious puberty. Injecting melatonin into animals will hinder the development of gonads in young animals, delay sexual maturity, inhibit the activity of gonads in adult animals, and shrink gonads and sexual organs. Excision of the pineal gland will increase the weight of the left side or testis. Therefore, scientists have concluded that "the most obvious effect of MLT on mammals is to inhibit the function of reproductive system" (Cheng Zhiping's Endocrine Physiology). In addition, melatonin can regulate the periodic changes of various physiological activities in the thermometer, inhibit the central nervous system and generally inhibit the endocrine system. (See the entry of pineal gland in biological volume and medical volume of Encyclopedia of China). Melatonin was allowed to be marketed as an auxiliary food in the United States on 1994 because of its inhibitory and sedative effects on the nervous system. On the outer packaging of melatonin sold in the United States, its purpose is marked: "It is believed that it can keep people in a regular sleep pattern" and it is stated that "this statement has not been evaluated by the FDA of the Federal Food and Drug Administration. Therefore, this product should not be used to diagnose, treat or prevent any disease. " Most experts believe that melatonin has certain effect on improving sleep. Melatonin has an inhibitory effect on the nerve center, so it helps to improve sleep. But melatonin is only effective for some insomnia patients. Why is this? First of all, there are many reasons for insomnia, such as insomnia caused by psychological factors, melatonin is ineffective; Secondly, the dose of melatonin is uncertain. Some people are very sensitive and have a great reaction when taking 1 mg, while others take 6000 mg without any problems. In other words, the effective range is 6000 mg and the normal dosage is 3 mg, which is not suitable for most users. Other experts hold a negative view. For example, Mr. Rao Yi, an associate professor of neurobiology at the Medical College of Washington University, a researcher at the China Academy of Sciences and a professor at Tsinghua University, thinks that it has an effect on the sleep of a few people, mainly as a placebo, because taking a blank control without drugs has a similar effect.

Since 1997, melatonin has been introduced to China by many manufacturers, and melatonin is only one of them. Melatonin is a trade name given to its melatonin products by Zhuhai Kangqi Co., Ltd. Different from others, melatonin is mixed with a bottle of hawthorn and poria oligosaccharide (isomaltooligosaccharide) oral liquid in addition to melatonin capsules. Why do you want to put these two things together? From the function of the product, the capsule helps sleep, and the oral liquid moistens the intestines to relieve constipation. The compatibility of the two has no additive effect. Unless a person can't sleep well and defecate well at the same time, what is the need to eat two things at the same time? The combination of these two things will also lead to a joke: Poria cocos and hawthorn juice are called the components of melatonin, and "melatonin" is also said to be a hormone secreted by the human body, which means that the human body secretes hawthorn and poria juice to control human aging. As for the laxative effect of oral liquid, because it is not the main function of melatonin, no one has studied and evaluated it at present. But one thing is clear, for a person with normal bowel movements, it is meaningless to take this kind of thing. Melatonin products are named "Melatonin", which is suspected to be illegal. Article 27 of the Product Quality Law of People's Republic of China (PRC) stipulates that "the mark on the product or package must be true. The annex 1 of the food labeling standard issued by the Ministry of Health 1996 stipulates that "exaggerated or misleading names shall not be used in health food". The name melatonin violates the above regulations. First, melatonin is only one of dozens of hormones in the human body, and some ordinary physiology books have not introduced it. Calling melatonin "melatonin" exaggerates its function and makes people mistakenly think that it is an extremely important substance in the human body. Second, the name of melatonin is easily mistaken for a brain-strengthening product, especially the brain-strengthening product brain gold developed by the former giant group. China Youth Daily, China Business News, etc. It has been reported that it is included in brain tonic products, even in the market analysis reports of some commercial consulting companies, which shows that there are many misunderstandings.

The oral liquid in melatonin is similar to "Sanzhu" and "Weili". The main component is oligosaccharide, which is isomaltose. This thing can promote the growth of bifidobacteria in the intestine. Bifidobacterium is a kind of beneficial bacteria. But there is a secret here: the flora in the human body is stable from birth, and normal people don't need extra supplements. Intestinal poisoning says that when people get old, the intestines get old first, and there is no scientific basis. Aging is still a mystery, but it is certain that human organs and tissues are aging at the same time. In order to deceive consumers, Shi Yuzhu also learned a trick from "Zhu San"-to ensure that consumers feel effective. One function of melatonin is farting. The instructions of melatonin particularly emphasize that after taking melatonin, we should pay attention to "the number of stools per day, the color of stools and whether they float on the water" and "the degree of fart smell compared with children". "If something happens, it means that the human body has begun to enter a beautiful and young state." These things may have the function of farting. Old people fart a lot. I don't believe it. This is the skill of entrepreneurs.
