Vitamin D3 and vitamin K2 work together to support key aspects of bone and cardiovascular health. D3 contributes to the normal absorption and utilisation of calcium, while K2 helps maintain normal bone and teeth structure by directing calcium to the right places. This combination also contributes to the normal function of the immune system. Taken as part of a balanced diet, this supplement provides these nutrients in active forms, which the body can readily use to support overall wellness.
