Vitamin D is an essential nutrient that helps the body absorb calcium and maintain strong bones. The recommended dosage for vitamin D varies depending on age, sex, and other factors. According to the Office of Dietary Supplements [2], the recommended daily intake of vitamin D for most adults is 600-800 IU (international units) per day. However, some individuals may require higher doses, such as those with a vitamin D deficiency or certain medical conditions.

It is important to note that the recommended dosages for Lipitor and vitamin D may vary depending on the individual's specific medical condition and other factors. Therefore, it is important to consult with a healthcare provider before starting any new medication or supplement regimen.
