Lipitor is a brand name for the drug atorvastatin, which is a type of medication called a statin that is used to lower cholesterol levels in the blood. Statins work by blocking an enzyme in the liver that is responsible for producing cholesterol [1]. According to the first source, Lipitor is one of the most widely prescribed statins in the United States, and it has been available as a generic drug since 2011 [1].

While statins like Lipitor can be effective at lowering cholesterol levels, some people may prefer to try natural alternatives. According to the British Heart Foundation, there are several lifestyle changes that can help lower cholesterol levels, including eating a healthy diet, getting regular exercise, and quitting smoking [2]. In addition, there are several natural supplements that may help lower cholesterol levels, including plant sterols, psyllium, and omega-3 fatty acids [3].

It is important to note that natural alternatives may not be as effective as prescription medications like Lipitor for some people. Additionally, it is important to talk to a healthcare provider before starting any new supplements or making significant lifestyle changes to ensure that they are safe and appropriate for an individual's specific health needs.
