Prevalence Study of Vitamin D Deficiency and to Evaluate the Efficacy of Vitamin D3 Granules 60,000 IU Supplementation in Vitamin D Deficient Apparently Healthy Adults.

Abstract
Objective: The objective of this study was to assess the prevalence of vitamin D deficiency in apparently healthy urban adults and to evaluate the efficacy of vitamin D3 granules 60,000 IU supplementation in increasing serum 25 hydroxyvitamin D [25(OH)D] levels. Material and methods: Healthy adults in an urban hospital were screened for 25(OH)D (radioimmunoassay method). Those found to be deficient or insufficient in vitamin D (defined as 25(OH)D <30 ng/ml) were supplemented with oral cholecalciferol granules 60,000 IU/week for eight weeks. Serum 25(OH)D level was estimated at the end of 60 days. Results: A total of 510 subjects (age 19-66 years) were enrolled for the study. Baseline data was available for 474 subjects and 178 subjects consumed a total of eight sachets as per the study protocol. Of these 178 subjects, 94.94% subjects were found to be vitamin D deficient (<20 ng/ml) and the mean plasma vitamin D3 25(OH)D level was 9.36 ng/ml (±5.19) at baseline. At the end of the study, the mean 25(OH)D plasma level was noted to be 29.28 ng/ml (±13.57). The mean change from baseline was 19.92 ng/ml (±13.25). Among these 178 participants only 5.06% had 25(OH)D >20 ng/ml at baseline, which increased to 78.09% at the end of the study following vitamin D3 supplementation for eight weeks. Conclusion: This study showed that vitamin D deficiency is highly prevalent in the urban healthy adult population. Eight weeks of vitamin D3 60,000 IU/week oral granules supplementation increased serum 25(OH)D to optimal levels.
