The Sun Vitamin D3 plays a central role in calcium metabolism and thus contributes to the maintenance of normal bones and muscles. Vitamin D is also needed for the immune system to function normally.
Vitamin K2 is important for the mineralization of bones and for normal blood clotting and should be taken in conjunction with vitamin D. In this optimal combination, the body receives the necessary nutrients in a practically dosable drop form.
