Ascorbic Acid + Nicotinamide + Pyridoxine Hydrochloride + Riboflavin + Vitamin A + Vitamin B1 + Vitamin D is a combination 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.
• 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 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 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.
• 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.
