Vitamin D3 K2 Komplex | Shield: what can you do yourself?

A Vitamin D3 K2 complex is often marketed for bone and cardiovascular health. What you can do yourself: First, get your vitamin D level (25-OH vitamin D) measured via a blood test – self-testing or a doctor visit is advisable, as overdosing can be harmful. Vitamin K2 (especially MK-7) is proposed to direct calcium into bones rather than arteries, but the evidence is moderate and mostly from observational studies. A balanced diet with green leafy vegetables (K1) and fermented foods (K2) is a safe foundation. Only supplement if a deficiency is confirmed and under medical guidance, especially if you take blood thinners (vitamin K antagonists). The D3+K2 combination is plausible but not proven by large RCTs for the general population. Self-initiative means: educate yourself, test, and remain critical.
