Dexpanthanol + Nicotinamide + Vitamin A + Vitamin B1 + Vitamin B12 + Vitamin B2 + Vitamin B3 + Vitamin B6 + Vitamin E is a combination preparation of different vitamins.

Dexpanthanol: It is an analogue of pantothenic acid, the synthetic form of vitamin B5. It helps to produce energy from the food we take. Vitamin B5 is an antioxidant and a neural component that aids in immune system and neural function enhancement. It also helps with fat metabolism and stress reduction.

Nicotinamide: Nicotinamide is converted into two essential coenzymes in the human body: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Many important events require both NAD and NADP, including energy synthesis, DNA repair, and cell death regulation.

Vitamin A: Also known as retinol, serves several functions. It Aids in the proper functioning of the body's natural defense against illness and infection (the immune system). It also aids vision in low-light situations. It is essential for the health of the skin and the lining of some body parts, such as the nose.

Vitamin B1: Often known as thiamine, in one of the 8 essential vitamins which means that our body cannot produce this vitamin on its own. It is soluble in water. Vitamin B1 allows the body to utilize carbohydrates for energy. It is required for glucose metabolism and is important for nerve, muscle, and cardiac function.

Vitamin B12: Vitamin B12 is required for the proper function and development of almost all the organ systems, including the brain, nerves, and blood cells. Methyl cobalamin is the active form of vitamin B12. 

Vitamin B2: Also known as riboflavin, Vitamin B2 acts in conjunction with the other B vitamins. It is necessary for the development of the body. It aids in the formation of red blood cells. It also assists in the energy release from proteins. Riboflavin aids in the conversion of carbohydrates to adenosine triphosphate (ATP).

Vitamin B3: Vitamin B3 functions in the body after being converted to nicotinamide adenine dinucleotide (NAD) by the NAD coenzyme system. Niacin (but not nicotinamide) in gram doses lowers total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG), while increasing high-density lipoprotein cholesterol (HDL-C). The magnitude of individual lipid and lipoprotein responses may be affected by the magnitude and type of underlying lipid disorder.

Vitamin B6: Vitamin B6 benefits the central nervous system and metabolism. Its roles include turning food into energy and helping to create neurotransmitters, such as serotonin and dopamine. 

Vitamin E: Vitamin E  has antioxidant properties. This means that it protects body tissue from damage caused by free radicals. Free radicals can cause damage to cells, tissues, and organs. They are thought to play a role in certain aging-related conditions. It aids in the defense of the immune system against viruses and bacteria. It aids in the formation of red blood cells and the widening of blood vessels, which prevents blood from clotting within them.
