Regular use of the K2D3® preparation helps prevent osteopenia and osteoporosis. It makes bones stronger and more resistant to fractures, prevents the occurrence and accelerates the healing of fractures. An important function of vitamin D3 in the body is to control the absorption of calcium from food in the intestines. In order for the body to be able to use this calcium properly, vitamin K2 is necessary, which prevents the formation of calcium deposits in soft tissues (joints, kidneys, breast, blood vessels...) and embeds calcium directly in the bone. In the absence of vitamin K2, calcium is deposited in soft tissues and leads to long-term dangerous calcification of joints and organs. That is why it is always necessary to take vitamin K2 along with vitamin D3
