Vitamin is a collective term for a series of organic compounds. They are micronutrients needed by organisms, and generally, they cannot be produced by organisms themselves and need to be obtained through diet and other means. Vitamin is not a component of body tissues and cells, nor does it produce energy. Its role is mainly to participate in the regulation of body metabolism.
Organisms require very little vitamins, and the daily requirement is often calculated in milligrams or micrograms, but lack of vitamins can cause serious health problems; excessive intake of vitamins can lead to poisoning.
According to solubility, it can be divided into fat-soluble and water-soluble vitamins. Water-soluble vitamins include all B vitamins, vitamin C, biotin (also known as vitamin H or coenzyme R), inositol, and vitamin PP; fat-soluble vitamins include Vitamin A, D, E, K, etc. Vitamins A, C, E, and part of the B family (B3, B5) are produced and demanded in large quantities. They are a large variety of vitamin products, especially VC's global annual production capacity of 200,000 tons, which is the largest vitamin variety. VB3 (niacinamide) also has About 100,000 tons; the production and demand of folic acid, vitamin B2, vitamin B6, and biotin are small, and the global production and demand are below 10,000 tons, which is a small variety of vitamins.
VE is a fat-soluble vitamin with a strong antioxidant capacity, which can improve the body's immunity and fertility.
The role of vitamin E:
Anti-aging: The principle of vitamin e anti-aging is inseparable from anti-free radicals. Vitamin E is highly effective against free radical lipid peroxidation.
Enhance immunity: Vitamin E deficiency affects the immune function of humans and animals. It not only reduces humoral immunity but also has a great impact on cellular immunity.
Resolve stains: When it comes to stains, everyone immediately thinks of chloasma and age spots on the face. They are all caused by the deposition of lipofuscin in skin cells. Lipofuscin is an inert waste product produced by cells oxidized by free radicals. This substance can not only appear in the form of various spots on the face, it can also be deposited in the heart, liver, and brain cells. The biggest function of vitamin E is to neutralize free radicals, which is conducive to the elimination of these spots. In addition, vitamin E also has the effect of dilating peripheral blood vessels and reducing blood viscosity.
Anti-tumor: Studies have found that the incidence of cancer seems to be inversely related to serum vitamin E levels: people with low vitamin E levels have a higher incidence of cancer.
Foods containing vitamin E:
Vitamin E is mainly found in plant foods. In addition, almost all green leafy vegetables contain vitamin E. Vegetable oil is the best food source of vitamin E. Foods which are rich in vitamin E include sesame, walnuts, lean meat, peanuts, lettuce, cabbage, etc., in addition to soybeans, peanuts, walnuts, melon seeds, animal liver, egg yolks, cream and corn, Yellow and green vegetables are rich in vitamin E. Milk, eggs, and cod liver oil also have a certain content of vitamin e
Vitamin B is water-soluble, which means that the body does not store vitamin B. Vitamin B that is not absorbed that day will be excreted with body fluids. Therefore, people must provide their bodies with new B vitamins every day. Due to factors such as age, pregnancy, diet, medical conditions, genetics, drugs, and alcohol, some people need to supplement vitamin B in addition to their diet.
B1 (thiamine): B1 converts nutrients into energy and plays a vital role in metabolism. The foods richest in B1 include pork, sunflower seeds, and wheat germ.
B2 (riboflavin): B2 converts food into energy and plays an anti-oxidant effect. Foods with the highest B2 content include offal, beef, and mushrooms.
B3 (Nicotinic acid): B3 plays an important role in cell signal transmission, metabolism, and DNA production and repair. Food sources include chicken, tuna, and lentils.
B5 (Pantothenic acid): Like other B vitamins, B5 helps your body get energy from food and also participates in the production of hormones and cholesterol. Liver, fish, yogurt, and avocado are all good sources.
B6 (pyridoxol): B6 is involved in amino acid metabolism, erythropoiesis, and neurotransmitter production. Foods with the highest vitamin B6 content include beans, salmon, and potatoes.
B7 (Biotin): B7 is necessary for carbohydrate and fat metabolism. Yeast, eggs, salmon, cheese, and liver are the best food sources.
B9 (folate): B9 is necessary for cell growth, amino acid metabolism, red and white blood cell formation, and cell division. It can be found in foods such as green leafy vegetables, liver, and legumes, as well as in folic acid supplements.
B12 (cobalamin): B12 is probably the most famous of all B vitamins. It is essential for nerve function, DNA production, and red blood cell development. The natural sources of B12 are meat, eggs, seafood, and dairy products.
