It also supports proper calcium and phosphorus absorption and helps maintain normal blood calcium levels. Vitamin K2 MK‑7, the highly absorbable form used in this formula, contributes to normal blood clotting and supports bone health.
Together, vitamins D3 and K2 offer complementary benefits, making this supplement a valuable addition to a balanced routine.
