Ascorbic Acid + Calcium d-Pantothenate + Cyanocobalamin + Folic Acid + Nicotinamide + Pyridoxine Hydrochloride + Riboflavin + Vitamin B1 is a combination preparation of different B vitamins and Vitamin C.

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.

Calcium d-Pantothenate: 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.

Cyanocobalamin: Cyanocobalamin is the synthetic form of vitamin B12, which is metabolized by the body into the active form. 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. 

Folic acid: Folic acid plays an important role in DNA, RNA and Protein biosynthesis. Folic acid is converted into tetrahydrofolate in the body which is the active form.

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).

Vitamin B1: 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.
