Mivolis Vitamin D3 + Selenium effervescent tablets help maintain a normal immune system. Vitamin D is known as an "all-rounder" and is required for a variety of tasks in the body, including the maintenance of normal bones, teeth and muscle function, the normal absorption of calcium and phosphorus and the normal function of the immune system. The contained pantothenic acid contributes to the normal synthesis and metabolism of vitamin D and some neurotransmitters. Vitamin D, the sun vitamin, can be formed by the human organism itself through regular exposure to sunlight. Nevertheless, in months with little sunshine or when there is not enough time outdoors, the supply for in-house production is not always sufficient and a supplement can be useful. In contrast to vitamin D, selenium cannot be produced by the body itself and must be taken in regularly through food. In addition to supporting the immune system, the trace element also helps protect the body cells from oxidative stress and also contributes to normal thyroid function.
