Mixing Lipitor (atorvastatin) with probiotics may pose risks as probiotics can interact with medications like Lipitor. Probiotics can potentially affect how the body absorbs certain medications, including atorvastatin, which is a medication used to lower cholesterol levels. According to the National Health Service (NHS) in the UK, it is advisable to consult a healthcare professional before taking atorvastatin with any other supplements, including probiotics, to avoid any potential interactions or adverse effects [2]. The Mayo Clinic also highlights the importance of being cautious when combining herbal supplements with medications, as interactions can occur that may affect the effectiveness or safety of the medication [3]. Therefore, it is recommended to seek advice from a healthcare provider before combining Lipitor with probiotics to ensure the safe and effective use of both.
