Abstract

Background: Hypovitaminosis is widely prevalent in India with limited data on vitamin D supplementation regimens.
Objective: We studied efficacy and safety of vitamin D supplementation as per the Endocrine Society Clinical
Practice Guidelines (ESCPG) in vitamin D deficient subjects.
Design: Fifty two healthy subjects had their serum albumin, creatinine, calcium, alkaline phosphatase, 25 OH
vitamin D (25OH D) and ntact PTH estimated at baseline, two and five months of supplementation. They were
supplemented with Cholecalciferol 9572 IU/day and elemental calcium 1 gm/day. At the end of the 2nd month, those
who attained vitamin D sufficiency were supplemented Cholecalciferol 3000 IU/day, and those still did not attain vitamin
D sufficiency with Cholecalciferol 5286 IU/day along with 1 gm elemental calcium and the later were reassessed after
three months.
Results: The mean ± SD of serum calcium, phosphorous, alkaline phosphatase were in the normal range at
baseline, 2 and 5 months of supplementation (P= NS). The baseline median (IQR-Interquartile range) of 25 OHD and
PTH was 6 (4-11) ng/ml and 19.6 (33-62) pg/ml respectively. At 2nd month there was threefold increase in 25 OHD
levels 19.6 (14.6-28.75) ng/ml and further 50% increase at 5th month of supplementation. PTH levels were suppressed
by 38 % at 2nd month and remained stable at 5th month. At end of 5th month, 46% had attained vitamin D sufficiency
and 27% of subjects were still vitamin D insufficient.
Conclusions: Vitamin D supplementation based on recent ESCPG even up to upper tolerable intake levels (UL)
along with elemental calcium of 1gm/day is safe and does not lead to hypercalcemia.
