The discovery of molybdenum was attributed to the lush green grass of New Zealand. It has been found that molybdenum is one of the seven micronutrient elements needed for plant growth and development. In the soil lacking molybdenum, adding some molybdenum fertilizer appropriately can increase the nitrogen fixation ability of crops, make crops grow better and increase the yield.
In addition, molybdenum is an essential micronutrient element for animals, plants and human body. Molybdenum is an important component of nitrogenase, nitrate reductase, xanthine oxidase, sulfite oxidase and other enzymes, and is involved in and affects various metabolic processes in animals.
The amount of molybdenum in the human body is very small, accounting for only one part per million of body weight. Although the content of molybdenum is very small, it plays an important role in human life that cannot be ignored. Heart muscle is known to contain a high proportion of molybdenum, which, along with some enzymes, maintains energy metabolism in the heart muscle. The hearts of dozens of people who died from myocardial infarction were analyzed and found to contain lower levels of molybdenum than healthy people. This indicates that the amount of molybdenum in the human body directly affects the function of the cardiovascular system, and also indicates that molybdenum has a special role in maintaining the normal function of the heart.
In recent years, the study found that molybdenum can interrupt the nitrosamines strong carcinogen in the human body synthesis, so as to prevent cancer. Increase the content of molybdenum in human body appropriately, can reduce or eliminate digestive tract cancer not only, still can improve blood circulation, prevent hypochromic sex anaemia.
Experts also found that molybdenum has an obvious anti - caries effect. The incidence of dental caries in children is very high in some areas with molybdenum deficiency or in people with molybdenum absorption disorders. Once the intake of molybdenum is increased, the effect of caries prevention is obvious. For this reason, it is suggested to produce molybdenum-containing toothpaste to open up a new way to prevent dental caries.
Other benefitsMolybdenum is
• an indispensable trace element in the formation of uric acid.
• Molybdenum is an important component of many enzymes. It involves the use of iron in the body, which prevents anemia, promotes development, and helps with carbohydrate and fat metabolism.
• Maintain myocardial energy metabolism to prevent Keshan disease.
• Maintain arterial elasticity and prevent cardiovascular disease.
• Maintain the bodys immune function.
• Regulate the thyroid.
• Prevent tooth decay, kidney stones, cancer, etc.
• Molybdenum is an important component of the iris of the eye.
• Prevent some rare genetic diseases.
Molybdenum supplement planAdults generally need 0.15 to 0.3mg of molybdenum per day. Because it is widely found in foods such as chrysanthemums, wheat, beans, milk, eggs, pork and honey, and because the human bodys requirement for molybdenum is extremely low, it is generally not deficient.
Some people lack molybdenum, in addition to consideration of environmental or dietary factors, but also to pay attention to the absorption and use of molybdenum by the human body itself. For example, in patients with molybdenum deficiency due to gastrointestinal dysfunction, the diagnosis and treatment of the primary disease and its etiology should be strengthened while supplementing the molybdenum-containing diet. You can eat more food rich in molybdenum to improve the content of molybdenum in the human body.
Anyone who talks about harm and not dose is acting like a rascal.Although molybdenum is a "heavy metal" by definition, it is far from the risk standard in the consumer goods and articles of daily life that it is exposed to.So molybdenum is not a monster, its just one of the elements that make up our life and our world.
