Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body [1]. Calcium supplements, on the other hand, are taken to improve bone health and prevent osteoporosis [2].

There is limited information on whether Lipitor affects the absorption of calcium supplements. However, a study published in the Journal of Clinical Endocrinology and Metabolism found that taking atorvastatin along with vitamin D supplements did not affect the absorption of calcium in postmenopausal women [3].

It is important to note that calcium supplements should be taken at a different time than Lipitor to avoid any potential interaction. Lipitor should be taken at the same time every day, while calcium supplements should be taken with food to aid in absorption [2].

It is recommended to consult with a healthcare provider before taking any new medication or supplement, as they can provide personalized advice based on individual health needs and medication regimens.
