Melatonin does not have absolute side effects, but when melatonin reaches a certain dosage, a small number of people may experience side effects such as inhibition of gonadal development, drop in body temperature and infertility.
Melatonin originates from the pineal gland inside the human brain and has physiological functions such as regulating jet lag, anti-aging, regulating immunity and promoting sleep. With the development of science and technology, it is now possible to achieve synthetic melatonin, when taking melatonin normally, generally will not appear obvious side effects, but need to be different from person to person.
However, according to relevant research organizations, some people can inhibit gonadal development after taking melatonin, resulting in decreased libido in men and women, decreased sperm health, inhibiting female ovulation and other side effects. Melatonin may also cause a drop in basal body temperature and infertility, but the chances of this occurring are small.
In daily life, healthy people do not need excessive melatonin supplementation, and melatonin does not have the role of treating diseases, only as a health care product to use, and can not replace drugs.
