More details about ingredients
Vitamin D3 (cholecalciferol) is also called the “sunshine vitamin” because the human body synthesizes it in the skin upon exposure to sunlight. Despite the fact that our body produces vitamin D3 under the influence of sunlight, the resources obtained in this way are quickly depleted. In the cold season when sunlight is reduced, it is recommended to supplement the diet with foods rich in vitamin D (salmon, herring, sardines, tuna oil, cod, turbot, egg yolk, brewer's yeast, etc.) or with nutritional supplements.
Vitamin D3 plays an essential role in the body. An optimal level of vitamin D3 supports good functioning of the immune system during periods of increased risk of illness, but also during periods of intense prooxidant activity (intense physical or intellectual activity). Studies show, moreover, that vitamin D enhances the functions of the immune system up to 5 times (Ginde AA, Mansbach JM, Camargo CĂ., Jr. Association Between serum 25 – hydroxyvitamin D level and upper respiratory tract infection in The Third National Health and Nutrition Examination Survey. Arch Intern Med. 2009; 169 384-90).
Vitamin D3 contributes to the optimal absorption and use of calcium and phosphorus, which leads to the maintenance of normal calcium concentration in the blood and the maintenance of healthy bones and teeth.
Vitamin D3 supports the normal functioning of the muscular system and contributes to cell division.
