Ostoforte is tablet consisting of vitamin D12, which is known medically as ergocalciferol. We carry the generic alternative of this medication in 50000iu. 

The most common uses of Ostoforte include hypoparathyroidism, rickets, and hypophosphatemia. Hypoparathyroidism is an uncommon disorder where the body is not capable of producing (enough) parathyroid hormones. This hormone, along with vitamin D and calcitonin (another hormone), help regulate the amount of calcium in the blood. If this goes untreated, it can cause hypocalcemia (an abnormally low level of calcium in the blood). This may result in muscle cramps or rightness, tingling of the lips or fingers, and rarely, seizures may occur. Rickets are when bones become soft and weak due to a deficiency in calcium, vitamin D, or phosphate. People with rickets may also have stunted bone growth and in some cases, skeletal deformities. Hypophosphatemia is one of the causes of rickets; hypophosphatemia is a phosphate deficiency, which means there are abnormally low levels of phosphate in the blood. This condition may cause on to feel weak, with troubles breathing and a loss of appetite. Complications such as seizures, coma, or rhabdomyolysis.

All of these conditions can be treated with Ostoforte/vitamin D2 (ergocalciferol) because vitamin D helps your body absorb calcium from the sun, and all these conditions stem from a lack of calcium.
