": Vitamin D plays an important role in strengthening our immune system. Since vitamin D is a pro-hormone produced by our skin when exposed to UV rays, the skin needs sunlight or supplements to produce it. Vitamin D is also present in some foods, but its concentration is significantly inferior to the amount of vitamin obtained from supplements. Vitamin D3 (or cholecalciferol) is a biologically active substance belonging to the group of fat-soluble. It has been proven that it regulates calcium-phosphorus metabolism, which is necessary to enhance the absorption of calcium from the stomach and delivery to various tissues of the body, as well as the reabsorption of phosphorus in the renal tubules, therefore, with a deficiency of vitamin D3, the content of calcium and phosphates in the blood decreases."
