At present, many chemical elements 1 10 have been found, among which 92 natural chemical elements and 8 1 chemical elements can be found in organisms.
According to the roles and functions of chemical elements in human and animals, chemical elements can be divided into essential elements, non-essential elements and harmful elements. Essential elements are also called life elements, and life elements can be divided into macro-element boxes and trace elements according to their contents in human body.
Macro-elements: The mass in human body accounts for more than one ten thousandth, including carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, chlorine, calcium, potassium and sodium.
Trace elements: refers to the life elements whose content in human body is lower than 0.0 1% to 0.005% of human body weight. There are more than 70 kinds of trace elements, including iron, zinc, selenium, copper, manganese and germanium.

Physiological functions of trace elements
1 Trace elements can catalyze the enzyme. At present, it is known that 1/3 needs the participation of metal ions, which are called coenzymes or auxiliary groups or auxiliary factors and are composed of trace elements. The enzymes involved in these metals are divided into metal activating enzymes and metal enzymes. Metal-activated enzymes must be combined with trace elements when they play a catalytic role, otherwise these enzymes will lose their function.
2 Trace elements promote human immune function
Human immune function: it is the ability of human body to resist the invasion of various bacteria and viruses. The level of human immunity often determines people's health. In human immune function, too much or too little intake of trace elements will cause disorder and lead to decreased immunity. When trace elements are deficient in the body, the direct consequence is that the immune organs of the body shrink and the immune ability of humoral immune box cells decreases.
3 Trace elements promote the formation of functional protein.
There are many kinds of protein in the human body, and some protein are responsible for functional work, such as detoxification, transportation and anti-inflammation. These functional proteins need the participation of trace elements to play their unique functions. If the human body lacks trace elements, it will affect the normal function of functional protein.
Trace elements control the secretion of hormones.
Hormone is the most efficient bioactive substance in human body, which directly affects growth and development and even causes diseases. Most hormones need the participation of trace elements.
Trace elements are closely related to nucleic acids.

Seabuckthorn contains trace elements.
The oldest element-iron
Biological function: participate in the production of blood in oxygen transport box. The daily iron requirement of adult males is 12 mg, and that of females is 12mg.
Iron deficiency in human body can lead to dyspnea and palpitation. Fatigue, fatigue, loss of appetite, swelling and ulceration of the tongue and corners of the mouth, decreased immunity, mental retardation, deafness and other symptoms.
four
Anti-cancer trace element selenium
Biological function: Selenium has the functions of anti-cancer, anti-aging and anti-oxidation.
Selenium exists in almost every cell, especially in kidney, liver, spleen, pancreas and testis. Adult men consume 70 micrograms a day, and adult women consume 55 micrograms.
1 Selenium deficiency in human body will not only cause cancer, but also cause Keshan disease, Kaschin-Beck disease and cataract.
Selenium is a strong antioxidant, which always protects cells and cell membranes from free radicals. When dealing with free radicals, selenium will also cooperate with vitamin E and cooperate with each other. Complement each other.
3 Selenium can fight cancer:
(1) can affect the metabolism of some carcinogens in the body.
(2) Anti-oxidation, avoiding cell membrane damage
(3) inhibiting the mutation of carcinogens
(4) Activate human immune system and enhance the fighting capacity of T cells.
(5) regulating the expression of tumor suppressor genes
Selenium can also protect blood vessels and the heart, and selenium can reduce the occurrence of thrombosis, thus greatly reducing the risk of heart box stroke.

The Spark of Youth —— Zinc
Biological function of zinc;
1 is an important mineral that constitutes cells.
Participate in the composition of more than 300 kinds of enzymes in human body, especially those in reproductive system.
3 also has antagonistic effect on the damage of harmful heavy metals cadmium and lead to cell membrane, thus inhibiting the damage of free radicals to cell membrane.
4 zinc deficiency can cause immune decline, and zinc deficiency is the most fatal cause of thymic box lymphatic atrophy, and the weight of thymus decreases by 20%-40%, thus causing T cell function damage and cellular immunity decline, and then fatal diseases such as cancer will take advantage of it.
Once the human body is short of zinc, the growth and division of cells will be hindered, and the development of skin and bones will be delayed. Male infertility, female secondary sexual dysplasia.
six
The unsung hero of hematopoiesis-copper
Biological function of copper;
1 copper deficiency in human body can cause iron deficiency anemia.
2 is an essential substance for the formation of human collagen. Collagen is the basic protein of bone, skin and connective tissue.
Copper is also related to the formation of melanin. Lack of copper in human body will lead to baldness and vitiligo.
Copper is also an expert in detoxification, which can stimulate superoxide dismutase to scavenge superoxide anion free radicals and induce cancer cells to commit suicide.
seven
Love Element-Manganese
Biological function of manganese;
1 once the human body lacks manganese, its ability to synthesize hormones and get pregnant will be reduced.
Anti-aging, can improve the synthesis of hormones in the body, can activate a series of enzyme activities, thus stimulating the hypothalamus and pituitary gland to maintain good physiological functions, making people healthy and young.
It has the function of caring skin. Appropriate amount of manganese can regulate the secretion of adrenaline, remove dead skin accumulated on the skin surface, restore skin elasticity and reduce the appearance of wrinkles.

Three elements
Macro-elements are indispensable elements in human life, which are relatively abundant in human body, accounting for more than one-tenth of the mass of human body.
Calcium-the source of life
Calcium accounts for 1.5%-2% of human body weight. 99% of calcium in human body is concentrated in teeth and bones, and the remaining 1% is dispersed in blood and muscle. Foods with high calcium content mainly include dried sardines, dried shrimps and loach.
Classification of 1 calcium
(1) Functional calcium is a cell with blood input and plays an important role in maintaining life. It is also related to cell division, proliferation and differentiation. It is the contraction of skeletal muscle and smooth muscle. Excitement of sensory cells and nerve cells, wound coagulation and other substances indispensable for various physiological functions,
(2) Storing calcium is an important substance for building bones and supporting the body.
2 Biological function of calcium
(1) Without calcium, bones can't form, wounds can't coagulate, muscles lack strength, and various physiological and biochemical reactions can't occur, so life can't exist.
(2) Calcium deficiency can lead to osteoporosis, hypertension and arteriosclerosis, and calcium can also affect nerve conduction.
nine
Phosphorus-a Good Partner of Calcium
The average human phosphorus content is 680 grams. 85% is concentrated in bones and teeth.
Biological function of phosphorus
1 combines with calcium to form calcium phosphate. The optimum ratio of phosphorus and calcium intake is 1: 1.
2 can balance the pH of human body fluids. When human body fluids are acidified, people are bound to get sick.
Phosphate in blood can participate in regulating PH value and osmotic pressure, so that people can get rid of the trouble of acidic constitution and make the functions of brain, nerve and muscle work normally.
Magnesium —— Activator of Enzyme
Biological function of magnesium
1 There are more than 300 kinds of enzyme reactions related to magnesium in human body, such as participating in thermogenesis, protein synthesis, nerve conduction, muscle contraction, thermoregulation and blood pressure regulation. Without the assistance of magnesium, these biochemical reactions will stop and people's metabolism will be disordered.
2 Maintain the health of the heart. Because when the human body is short of magnesium for a long time, the circulatory system in the human body will be hindered, which will lead to angina pectoris and myocardial infarction.
3 is a rare anti-stress substance. When human body is deficient in magnesium, it will increase in cells, leading to various mental symptoms or neurological symptoms. Mental symptoms: causing depression, anxiety, paranoia and insanity, mainly causing nervous system allergy, tremor and muscle spasm.
