Objective: The present study evaluated the correlation between Vitamin D and Alkaline phosphatase levels among the Saudi
population. Methods: Blood samples of patients with a complaint of pain in various body parts and other clinical symptoms of
Vitamin D deficiency were tested for the levels of Vitamin D and ALP. The analyzes were carried out using SPSS version 20.0
software. Results: Vitamin D and ALP levels of 460 patients were analyzed. The mean levels of Vitamin-D and ALP were found to be
22.03±13.5 and 89.02±44.9. About 356 patients (77.4%) out of 460 had Vit-D deficiency, whereas 421 patients (91.5%) out of 460
had ALP at normal ranges. From the analysis based on the nationality, Saudi 223 patients out of 280 showed vitamin D deficiency
and 257 patients out of 280 had normal ALP levels. No correlation between serum ALP and vitamin D levels was observed (r = 0.05,
p = 0.2). Conclusion: serum alkaline phosphatase cannot be considered as a useful marker to represent the Vitamin D deficiency
among the population.
