Vitamin D is a fundamental substance for the well-being of the body. It contributes to the correct absorption and use of calcium and phosphorus and to the maintenance of normal bones and teeth. It must not be missing to maintain proper muscle function and assist that of the immune system. Food choices that exclude sources rich in Vitamin D, daily commitments, which force us to stay closed at home or in the office for most of the week, unfavorable weather conditions, especially during the winter season, which force us to go out little and cover ourselves well , and even advancing age, can sometimes make supplementing this Vitamin useful. Erbamea therefore suggests combining a varied and balanced diet and a healthy lifestyle with a Vitamin D3 supplement: from today you can also choose the new Vitamin D3 of vegetable origin, extracted from Lichen Cladonia rangiferina, the reindeer lichen, also suitable to vegetarians and vegans. Both the proposed Vitamin D3 supplements provide with 1 tablet 50 μg of Vitamin D3 (cholecalciferol) equal to 2000 International Units.
