Deranged vitamin D metabolism represents an active trigger of secondary hyperparathyroidism (SHPT) in CKD. Correction of 25(OH)D deficiency by nutritional Vitamin D administration is suggested by KDIGO guidelines, to prevent and treat SHPT in CKD stage G3-G5 and G1T-G5T patients, although with a still inconsistent background. Nutritional vitamin D is available as cholecalciferol, ergocalciferol, or calcifediol. Superiority of calcifediol in increasing 25(OH)D levels has been suggested due to its better bioavailability. The safer pharmacokinetic of the recent modified-release (MR) formulation of calcifediol was effective in replenishing 25(OH)D levels with minimal impact on vitamin D catabolism and fibroblast-growth factor-23 (FGF-23) activation. Areas covered: the review discusses utility of calcifediol for treating SHPT in different CKD stages under physiology driven approach, focusing on vitamin D metabolism, guidelines suggestions and comparison between clinical effects on SHPT elicited by calcifediol, cholecalciferol and ergocalciferol. Expert commentary: although optimal targets of 25(OH)D and parathormone remain uncertain, calcifediol, especially in its newer MR formulation, may represent an intriguing option to combine an efficacious correction of 25(OH)D deficit and SHPT, with a limited impact on vitamin D catabolism and FGF-23 activation. Newer data are required to better explore the role of MR calcifediol in treating SHPT.
