In recent years, the increase in interest and use of vitamin D has been attributed mainly to the effects of vitamin D on the extra-skeletal effects and confusion about normal reference values for serum 25OHD. However, The Institute of Medicine (IOM), which determines daily intake of nutrients, vitamins and minerals in the United States, emphasizes that there is no additional benefit of having a 25OHD level above 20 ng/ml in terms of PTH suppression, calcium absorption and "fall risk". Taking into consideration that there has not been a significant increase in vitamin D deficiency and related conditions in Turkey over the past 5 years, it is not hard to suppose that this increase is due to declarations of doctors who have shown vitamin D as a "panacea’’ in media platforms. This paper aims to answer some frequently asked questions such as the threshold values recommended for the evaluation of vitamin D status, the clinical indications for measuring 25OHD and suggestions on the use of lifelong vitamin D starting from pregnancy.
