Under the influence of ultraviolet radiation on our skin, a group of vitamins - ferols is activated, as a result of which calciferol is produced, which we know under the name - vitamin D. This useful element regulates the absorption of many minerals, participates in the metabolism of phosphates and calcium.All these actions normalize the functioning of the kidneys, intestines, parathyroid glands, stabilize the skeletal system, skeleton, prevent osteoporosis, and have an antibacterial effect on us.
