Solgar Vitamins D3 1000 IU Without sugar and without salt Food supplement 100 capsules Net Weight: 59.5g A fat-soluble vitamin, vitamin D3 (cholecalciferol) is much more effective than vitamin D2 (ergocalciferol) because it is much easier to store. Its role in the skeleton and teeth has long been known, but in recent years research has demonstrated the importance of vitamin D in regulating the immune system, as well as its involvement in the muscular and nervous systems, etc. More than 75% of French people have a vitamin D deficiency, defined as a blood level of 25(OH) vitamin D less than 30 nanograms per milliliter (ng/mL). Essential for the correct functioning of the immune system and the skeleton, Solgar offers a new vitamin D3, dosed at 1000 IU and available in softgel. Vitamin D3 (cholecalciferol) is the most effective form and its presentation in oily form improves its absorption. Solgar FRANCE 14 Rue de Berlin CS 20143 MONTEVRAIN 77772 MARNE LA VALLEE CEDEX 4
