An oral supplement called Cholecalciferol Softgel Capsules is used to treat and prevent vitamin D deficiency. When skin is exposed to sunlight, a form of vitamin D called cholecalciferol is created. In addition to controlling blood levels of calcium and phosphorus, it is crucial for maintaining strong bones and teeth. Cholecalciferol Softgel Capsules dosage will vary depending on the patient's age, weight, medical condition, and the severity of the vitamin D deficiency. The medication is typically taken orally, with or without food.
