Vitamin D3 2000 IU. (100 caps)

The sunshine vitamin – Vitamin D3 2000 I.U.    Vitamin D is a very special vitamin - in several ways: It belongs to the group of fat-soluble vitamins and can therefore be stored in the body, in contrast to water-soluble vitamins.   Since fat-soluble vitamins are absorbed along with fats, concomitant consumption of fat can therefore increase the absorption of these vitamins.   However, this also means that people who eat very low-fat foods only get small amounts of these vitamins into their bodies.   In addition, vitamin D is the only vitamin that can be produced by the body itself - through exposure to sunlight.    Vitamin D is important for numerous metabolic processes.   To do this, however, it must first be converted into a usable form in the skin, liver and kidneys, the so-called calcitriol (1,25-dihydroxycholecalciferol).   The vitamin D hormones, known as calcitriol derivatives, are needed primarily in the intestines and kidneys as well as in bones, muscles and nerves.   They influence the calcium and phosphate balance and ensure adequate absorption and storage of calcium.   But the prohormone also plays an important role in numerous other biological processes, especially in connection with the immune system.    Vitamin D has numerous important tasks in the body, and people who consume little fat in particular should pay attention to their vitamin D balance.
