The study involves children and adolescents aged 2 to 18 years. Two forms of vitamin D, known as colecalciferol or vitamin D3, will be used in the trial. These are available as oral solutions called ADRIGYL 10,000 UI/ml and UVEDOSE 100,000 UI. The purpose of the study is to evaluate how different ways of taking vitamin D, either as a high dose given at once or as a smaller daily dose, affect the occurrence of hypercalciuria.

Participants in the study will be randomly assigned to one of two groups. One group will receive a high dose of vitamin D at the start, while the other group will take a smaller dose daily. The study will last for 28 days, and urine samples will be collected on days 7, 14, and 28 to measure the levels of calcium. This will help determine if the way vitamin D is taken influences the development of hypercalciuria. Additionally, the study will monitor for any side effects or unexpected reactions to the vitamin D supplementation.
