Ascorbic Acid + Dexpanthanol + Nicotinamide + Pyridoxine Hydrochloride + Riboflavin + Sodium Acetate + Thiamine Hydrochloride + Vitamin A + Vitamin D + Vitamin E is a combination preparation of different vitamins.

Ascorbic acid: Also known as Vitamin C, is necessary for the growth, development and repair of all body tissues. It's involved in many body functions, including formation of collagen, absorption of iron, the proper functioning of the immune system, wound healing, and the maintenance of cartilage, bones, and teeth.

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.

Pyridoxine HCl: Pyridoxine Hydrochloride is a water soluble form of pyridoxine or Vitamin B6. Vitamin B6 is a vitamin that benefits the central nervous system and metabolism. Its roles include turning food into energy and helping to create neurotransmitters, such as serotonin and dopamine. 

Riboflavin: Riboflavin, also known as 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).

Sodium acetate: It is an organic salt of sodium. Na+ is an important electrolyte involved in various functions like neurotransmission.

Thiamine Hydrochloride: Thiamine Hydrochloride is a preparation of vitamin B1. It allows the body to utilize carbohydrates for energy. It is required for glucose metabolism and is important for nerve, muscle, and cardiac function.

Vitamin A: Also known as retinol, vitamin A 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 D: It is a fat soluble vitamin that helps the body to absorb calcium and phosphate. It plays an important role in bone and teeth formation.

Vitamin E: It 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.
