Juvamine Vitamins D 2000 IU Normal function of the immune system Food supplement 20 ampoules of 10 ml Net volume: 200ml Juvamine Laboratories have developed ampoules with a high dose of vitamin D3, which contributes to the normal functioning of the immune system and the maintenance of a normal bone structure. Vitamin D is synthesized by the skin under the action of the Sun, in the form of vitamin D3. Our modern lifestyle (often subway, work, sleep) limits our exposure to the Sun. Furthermore, during periods of low sunlight, particularly in autumn and winter, our production of vitamin D is reduced. In France, 80% of the population lacks it**. To more quickly compensate for any deficiencies, each ampoule provides 50 g or 2,000 IU (International Units) of vitamin D3.
