How Calacis-K27 works

Vitamin K2-7 decides where the absorbed calcium goes. It activates osteocalcin, the protein that binds calcium into the bone matrix, and matrix Gla protein, which keeps calcium out of arterial walls. Calcium and vitamin D get the mineral into the body; K2-7 directs it into bone rather than into blood vessels. Calcium citrate supplies the mineral bone is built from. Bone is not inert -- it is broken down and rebuilt continuously, and after about thirty-five the breakdown outpaces the rebuilding. Supplementing matters most where the loss accelerates: after menopause, during pregnancy and breastfeeding, and through the growth years when the skeleton is being laid down. Calcium citrate is absorbed without needing stomach acid, which matters in older people and in anyone on a proton pump inhibitor -- calcium carbonate depends on acid and is poorly absorbed in both. Calcium taken without adequate vitamin D is largely not absorbed at all -- which is why the two are almost always given together. Calcitriol is what allows the gut to take calcium up and what keeps blood calcium steady. Calcitriol is the already-active form of vitamin D. Ordinary vitamin D must be converted first by the liver and then by the kidney; calcitriol skips both steps, which is why it is used where kidney function is impaired or where a faster effect is wanted. Supplying them together is the point: each supports what the others are doing.
