Especially during the dark season, but often also during the summer, the vitamin D supply is sometimes insufficient. When a sunscreen is applied, the formation of vitamin D is prevented, as well as when staying in rooms and in artificial light. Even in old age, with a vegetarian diet, especially to strengthen bone strength, vitamin D is a useful supplement. Even people with a darker skin color should bear in mind that due to this protective function, the body cannot produce as much vitamin D3 on its own. In order to remedy a vitamin D3 deficiency in the body, vitamin D should be supplied in its purest form. In 1A. PURE SUBSTANCES Vitamin D capsules only contain 1000 I.U. (International Units) of vitamin D3 in its purest form with optimal bioavailability, of course, without any industrial additives.
