What the Evidence Says

✨ AI-generated · Qwen 3.6 · grounded in 1 source · methodology

Vitamin D3 and K2 work synergistically to support calcium absorption and bone health, with strong evidence supporting their roles in skeletal maintenance. Vitamin K2 specifically helps direct calcium into the bone matrix rather than arterial walls. Research indicates these nutrients are generally safe, though high doses of D3 require monitoring.
