Vitamin D3 & K2, 4000 IU/100 mcg, 60 capsule bottle

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone-7, MK-7) work synergistically in calcium homeostasis and bone metabolism. Vitamin D3 supports intestinal calcium absorption and helps maintain serum calcium levels, while vitamin K2 activates vitamin K–dependent proteins (such as osteocalcin and matrix Gla protein) that help regulate calcium deposition in bone and support vascular calcium balance. This coordinated activity supports bone mineralization while promoting healthy arterial elasticity and cardiovascular structure. Vitamin D3 also contributes to normal immune system function. Formulated with bioactive all-trans MK-7 in a hypoallergenic capsule.
