Vitamin D contributes to the maintenance of normal bones and teeth, as well as normal muscle function. It plays a role in cell division and supports the normal function of the immune system. It also contributes to the normal absorption and utilization of calcium and phosphorus, as well as to the regulation of normal calcium levels in the blood.*
According to the latest findings, vitamin D should always be taken in combination with vitamin K2 to prevent deposits.
Vitamin K is a fat-soluble vitamin that contributes to normal blood clotting and the maintenance of normal bones. The MK-7 All-Trans form is the most bioavailable form of vitamin K2 and can be optimally absorbed by the body. It is derived from natto (fermented soybeans) and is therefore 100% vegan.
Important: Vitamin K supplements should not be used by people taking anticoagulant medications from the vitamin K antagonist group.
Magnesium contributes to the normal function of the nervous system and muscles. It plays a role in cell division and supports normal protein synthesis and electrolyte balance. Magnesium also contributes to the maintenance of normal bones and teeth.*
