First, vitamin B, formerly known as vitamin B, is a general term for B (vitamin B) and belongs to water-soluble vitamins. They usually come from the same food source, such as yeast. It is an essential part of metabolism in the body, and each vitamin B participates in key metabolic reactions, usually in the form of coenzyme.
2. Biotin B is a water-soluble vitamin, which has a synergistic effect, regulating metabolism, maintaining the health of skin and muscles, enhancing the functions of immune system and nervous system, and promoting the growth and division of cells (including promoting the production of red blood cells and preventing anemia). Among them, vitamins B 1B6 and B 12 help to protect nerve cells, while vitamin B2 has antioxidant effect, and plants can synthesize vitamin B2. Animals generally can't synthesize vitamin B2, which is one of the essential elements to maintain the normal growth of animals.
First of all, if it is lacking, it may lead to growth stagnation or local damage.
Three, there are more than twelve kinds of B vitamins, and nine kinds of vitamins are recognized as essential for the human body, all of which are water-soluble vitamins. They only stay in the body for a few hours and must be replenished every day. B group is an essential nutrient for all human tissues and the key to the release of energy from food. They are all coenzymes, which participate in the metabolism of sugar, protein and fat in the body, so they belong to one family.
Fourth, all vitamin B must play a role at the same time, which is called VB fusion. When a certain VB is ingested alone, due to the increase of cell activity, the demand for other VBs increases, so the functions of various VBs are complementary, which is the so-called "Kanekin's Law". Dr Roger William pointed out that all cells have exactly the same demand for vitamin B.
The V b vitamins closely related to skin care are B 1. B2.B3.B5.B6 and h, etc. Vitamin B 1, also known as thiamine, can inhibit cholinesterase activity, reduce skin inflammatory reaction, prevent and treat seborrheic dermatitis and eczema, and improve skin health. Mainly from cereals, fresh vegetables, fruits, milk, egg yolk, lean meat, liver, yeast, bran, peanuts and so on. Vitamin B2, also known as riboflavin, is involved in the redox reaction of cells, the synthesis of hemoglobin and the metabolism of sugar, protein and fat, which can help the skin to resist the damage of sunlight and promote cell regeneration. When the human body lacks vitamin B2, the skin is sensitive to sunlight, and solar dermatitis is easy to occur. Exposure to the sun for a long time, the face is red and itchy, and powder appears around the nose. Mainly from egg yolk, milk, yeast, green leafy vegetables, rice bran, germ, animal liver and kidney, carrots, brewing yeast, fish, oranges, oranges and so on. Vitamin B3, also known as nicotinic acid, can inhibit the formation of melanin and prevent rough skin. Conducive to the recovery of damaged cells or skin. Sixth, it plays an important role in maintaining the integrity of normal tissues, especially the integrity of skin, digestive tract and nervous system. Vitamin B6 is closely related to skin health and is a part of the molecular structure of many enzymes and auxiliary enzymes. Promoting amino acid metabolism to maintain skin health can reduce capillary wall permeability and hyaluronidase activity, reduce allergic reaction and inflammatory reaction, and promote epithelial cell growth. Can be used for preventing and treating pachylosis, acne, sunburn, itching relieving and tanning, and can also be used for preventing and treating seborrheic skin inflammation, acne, seborrheic dermatitis, eczema and desquamation skin changes. Mainly from liver, egg yolk, grain, germ, beans, milk, fish, meat and vegetables. Vitamin H, also known as biotin, can promote skin metabolism, improve rough skin, and prevent alopecia, seborrheic dermatitis and acne multiforme. It exists in liver, egg yolk, milk, yeast and other foods.
