According to the sources provided, there is no significant interaction between Lipitor and Vitamin D.

Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood. According to DrugPatentWatch [1], Lipitor is a statin drug that works by inhibiting the enzyme HMG-CoA reductase, which is involved in the production of cholesterol in the liver.

Vitamin D, on the other hand, is a fat-soluble vitamin that plays a crucial role in the regulation of calcium and phosphorus levels in the body. It is obtained from sunlight exposure, diet, and supplements.

A study published in PubMed [2] investigated the effect of atorvastatin on vitamin D levels in patients with hyperlipidemia. The study found that atorvastatin did not significantly affect vitamin D levels in these patients.

Additionally, Drugs.com [3] lists no known interactions between Lipitor and Vitamin D. However, it is always important to consult with a healthcare provider before taking any new medications or supplements, as individual factors may affect drug interactions.

In conclusion, based on the sources provided, there is no significant interaction between Lipitor and Vitamin D. However, it is always important to consult with a healthcare provider before taking any new medications or supplements.
