Studies show that both adults and children are vitamin K deficient. This seems to correlate with the declining dietary intake of Vitamin K2. Bone tissue grows and develops intensively during childhood and adolescence, and children have the greatest requirement for active Osteocalcin and vitamin K. The most widely recommended Vitamin K2 dose today for children is 45 mcg daily, a dose clinically proven to increase the carboxylation, or activation, of Osteocalcin. However, future studies will show if especially growing children need additional Vitamin K2 in their diets.
