Brief Summary

Extra-renal sources of 1, 25-dihydroxyvitamin D can be increased to normal serum 1, 25-dihydroxyvitamin D levels in chronic kidney disease patients after administration of high dose 25-hydroxyvitamin D. The investigators observed that 1, 25-dihydroxyvitamin D concentrations were significantly increased after 3 months of omega-3 FA supplementation compared to baseline levels without 25-hydroxyvitamin D administration in dialysis patients. In this study, the investigators hypothesized that omega-3 FA and 25-hydroxyvitamin D supplementations may increase 1, 25-dihydroxyvitamin D concentrations much more compared to 25-hydroxyvitamin D supplementation only in hemodialysis patients with insufficient or deficient 25-hydroxyvitamin D levels.
