Design experiments prove that some trace elements are necessary for human health.

Trace elements needed to guide human body, such as iron, zinc, selenium, iodine, copper, manganese, chromium, fluorine, molybdenum, cobalt, nickel, tin, silicon and vanadium, are all essential trace elements for human body.

Suggestion:

Although the human body's demand for trace elements is very low, it plays a great role. For example, iodine can treat goiter and arteriosclerosis and improve intelligence and sexual function. "Strontium and chromium" can prevent hypertension, diabetes, hyperlipidemia and gallstones. "Zinc" is an important life-related element directly involved in immune function. Because zinc has immune function, the zinc content in white blood cells is 25 times higher than that in red blood cells. Manganese can stimulate the cell proliferation of immune organs, greatly improve the survival rate of macrophages, and has the functions of phagocytosis, sterilization, cancer suppression and tumor dissolution. Selenium is the main anticancer element in the immune system, which can directly kill tumor cells.
