Vitamin D3 + K2 delivers active forms of two essential vitamins that work together to support skeletal strength and cardiovascular health. Vitamin D3 enhances calcium absorption in the gut and reduces calcium loss through urine, helping to maintain healthy serum calcium levels. Vitamin K2-7 supports bone mineralisation by enabling the carboxylation of osteocalcin, a protein that binds calcium in the bone matrix. It also activates Matrix Gla Protein, which helps direct calcium away from arteries to support vascular elasticity and proper calcium metabolism.
This specific form of K2 concentrates in arterial tissue and has a longer half-life than other types, keeping blood levels more stable over time. Research links higher dietary intake of K2-7 with healthy arterial calcification levels and improved elasticity. The combination not only strengthens bones and teeth but also helps maintain healthy lipid levels and glucose metabolism. For best results, take Vitamin D3 + K2 with a mixed meal or a source of healthy fat to support absorption of these fat-soluble nutrients.
