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 25- OHD. 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
