As my background, I am a researcher with a PhD degree in Biochemistry from King Abdulaziz University, Saudi Arabia (Grade 4.98, of 2015). My scientific interests are vitamin D, obesity, PCOS, metabolism, and osteoporosis. Besides that, I won two scientific AWARDS and published many research papers. Nowadays, I have been working on several scientific research projects.
Vitamin D is a hot topic that has attracted attention over the past 10 years, especially since a large proportion of people suffer from this nutrient deficiency. Vitamin D deficiency is estimated to be about 1 billion people all over the world and 50% in Asia and the Middle East. Saudi Arabia has also demonstrated a high prevalence of vitamin D deficiency among healthy Saudi individuals. This chapter provides, in detail, a clear and understandable identification of vitamin D, its function, source, synthesis, metabolism, status, and deficiency. The chapter also focuses on studying vitamin D deficiency in Saudi Arabia based on PubMed’s initial research criteria.
