VB12
Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brainand nervous system, and for the formation of blood. It is one of the eight B vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid synthesis (especially odd chain fatty acids) and energy production. Neither fungi, plants, nor animals are capable of producing vitamin B12. Only bacteria and archaea have the enzymes required for its synthesis, although many foods are a natural source of B12 because of bacterial symbiosis. The vitamin is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis.
VB2
Riboflavin, also known as vitamin B2 and is the vitamin formerly known as G, is an easily absorbed colored micronutrient with a key role in maintaining health in humans and other animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. As such, vitamin B2 is required for a wide variety of cellular processes. It plays a key role in energy metabolism, and for the metabolism of fats,ketone bodies, carbohydrates, and proteins.
VB4
Adenine (formerly known as vitamin B4) is a purine that has many different functions in biochemistry. In cellular respiration, it acts in the form of energy-rich adenosine triphosphate (ATP), cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD). It is also used as a component of DNA and RNA in the process of protein biosynthesis.
VB5
Niacin (also known as vitamin B3 and nicotinic acid) is an organic compound with the formula C6H5NO2 and, depending on the definition used, one of the 20 to 80 essential human nutrients. Insufficient niacin in the diet can cause nausea, skin and mouth lesions, anemia, headaches, and tiredness. Chronic Niacin deficiency leads to a disease called pellagra. The lack of niacin may also be observed in pandemic deficiency disease which is caused by a lack of five crucial vitamins: niacin, vitaminC, thiamin, vitamin D and vitamin A, and is usually found in areas of widespread poverty and malnutrition. Niacin has been used for over 50 years to increase levels of HDL in the blood and has been found to decrease the risk of cardiovascular events modestly in a number of controlled human trials.
VB6
Pyridoxine is one of the compounds that can be called vitamin B6, along with pyridoxal and pyridoxamine. It differs from pyridoxamine by the substituent at the '4' position. Its hydrochloride salt pyridoxine hydrochloride is often used. It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.

Vitamin E refers to a group of eight fat-soluble compounds that include both tocopherols and tocotrienols. Of the many different forms of vitamin E,γ-tocopherol is the most common in the North American diet. γ-Tocopherol can be found in corn oil, soybean oil, margarine, and dressings. α-tocopherol, the most biologically active form of vitamin E, is the second-most common form of vitamin E in the diet. This variant can be found most abundantly in wheat germ oil, sunflower, and safflower oils. As a fat-soluble antioxidant, it stops the production of reactive oxygen species formed when fat undergoes oxidation. Amounts over 1,000 mg (1,500 IU) per day are called Hypervitaminosis E, as they may increase the risk of bleeding problems and vK deficiency.
VK
Vitamin K is necessary for the liver to synthesize four coagulation factors (active coagulation factor Ⅱ (prothrombin), coagulation factor Ⅶ, coagulation factor Ⅺ and coagulation factor Ⅹ). If vitamin K1 is lacking, the above four coagulation factors synthesized by the liver As abnormal protein molecules, their ability to catalyze blood clotting is greatly reduced. It is known that vitamin K is a cofactor for the carboxylation of glutamate gamma. Without vitamin K, the γ-carboxylation of the above coagulation factors cannot be carried out. In addition, these coagulation factors in the blood are reduced, and coagulation delay and bleeding disorders will occur. In addition, it is recognized that vitamin K is dissolved in the lipids of the mitochondrial membrane and plays an electron transfer role. Vitamin K can increase intestinal peristalsis and secretion. When vitamin K is lacking, smooth muscle tension and contraction are weakened. It can also affect the metabolism of some hormones.
VK1
Vitamin K1, also known as phytomenadione, phytyl menadione, phylloquinone, and its chemical name is 2-methyl-3-phytyl-1,4-naphthoquinone, which is a polycyclic aromatic ketone. It is a fat-soluble vitamin, stable to air and humidity, but will be decomposed in the sun. Exist widely in natural green plants.
VK2
Vitamin K2 is a collective term for a series of terpene side chain compounds containing 2-methyl-1, 4-naphthoquinone nucleus and a different number of isoprene structural units at the C3 position. According to the carbon on the terpene side chain The number of elements can be divided into K2(10), K2(20), K2(35), K2(40), etc. Vitamin K2 (35) is vitamin K2 with 35 carbon elements on the terpene side chain; vitamin K2 (35) is also known as menadione-7, which is based on the fact that there are 7 isoprene on the terpene side chain The alkene side chain is named.
Valsartan
Valsartan is used for the treatment of resistant hypertension, mild-to-moderate essential hypertension,especially for secondary hypertension caused by kidney damage.It can significantly reduce the high blood pressure patients' proteinuria associated with diabetes or abnormal renal function , and has functions of promoting the excretion of uric acid and renal to protect the kidney.
