Vigantolvit vs. Cefavit D3 K2: Bone Health Comparison

Both of these supplements utilize the powerful synergy of Vitamin D3 and K2 to direct calcium into the bones, but they take different approaches to the supporting minerals. Vigantolvit includes a massive 500 mg dose of actual Calcium, providing the physical building blocks for bone. Cefavit omits Calcium entirely, instead providing 150 mg of Magnesium, the crucial cofactor needed to biologically activate the Vitamin D.

The core engine is similar: Vitamin D3 absorbs calcium from the gut, and Vitamin K2 acts like a traffic cop, ensuring that calcium is deposited into the bones rather than calcifying the arteries. **The difference is the payload.** Vigantolvit assumes you need more calcium, providing 500 mg directly. Cefavit assumes you already eat enough calcium, so it focuses on providing 2000 IU of D3 (double the dose of Vigantolvit) alongside Magnesium, which is required by the liver and kidneys to convert that D3 into its active, usable form.

If your diet is generally poor in calcium-rich foods (like dairy or fortified greens), you need Vigantolvit to provide the literal bricks to build your bones. However, if you eat plenty of cheese and yogurt, adding excess calcium via supplements can sometimes lead to arterial stiffness. In that case, Cefavit is the smarter, modern choice, providing higher D3 and the Magnesium needed to activate it.
