Lipitor is a medication used to lower cholesterol levels in the blood [1]. Vitamin D is a nutrient that helps the body absorb calcium and is essential for strong bones and teeth [2]. According to the Mayo Clinic, vitamin D is generally safe for most people when taken in recommended doses [2]. The recommended daily allowance of vitamin D for adults is 600-800 IU [3].

There are no known interactions between Lipitor and vitamin D, and both can be taken together long-term [1, 2]. However, it is always important to consult with a healthcare provider before taking any new medications or supplements, as they can provide personalized advice based on individual health conditions and other medications being taken.
