Based on the information available, there is no direct evidence to suggest that Lipitor, a medication used to treat high cholesterol, affects plant-based iron absorption. Lipitor, also known as atorvastatin, is a type of statin that works by lowering the levels of low-density lipoprotein (LDL) or "bad" cholesterol in the blood [1].

Iron absorption can be influenced by various factors, including the form of iron (heme or non-heme), the presence of certain substances in food, and individual health conditions [2]. Plant-based foods contain non-heme iron, which is typically not as easily absorbed by the body as heme iron found in animal products [3].

While Lipitor is not known to interact directly with plant-based iron absorption, it is always recommended to consult with a healthcare provider, pharmacist, or nutritionist for personalized advice regarding medication use and dietary considerations [4].
