The active form of vitamin D is made in the kidney. Kidney dialysis patients have low amounts of activated vitamin D and need to be supplemented. Calcium must be given along with vitamin D or the vitamin cannot do its job. Calcium levels must be closely watched. If too much calcium is absorbed, the physician often stops the vitamin D supplements.
Calcium carbonate is a good supplement for calcium and phosphorus control.
Vitamin K Vitamin K is important in blood clotting. There is no evidence that kidney dialysis patients need vitamin K supplementation. The B vitamins are B1, B2, B6, B12, biotin, pantothenic acid, niacin and folic acid. Vitamins B1, B2, niacin, pahtothenic acid and biotin should be taken in recommended daily amounts. B6 and B12 are very important vitamins that act together to promote red blood cell development.
