It is important to follow the recommended dosage guidelines for vitamin C and to speak with a healthcare professional before taking any new supplements.

In conclusion, there is no known interaction between Lipitor and vitamin C [2]. However, it is always recommended to consult a healthcare professional before combining any medications or supplements.
