Based on the information available, there is no specific recommended time to take Lipitor (atorvastatin) with yogurt. Lipitor is a medication used to treat high cholesterol and prevent heart disease [1]. It's typically taken orally once a day, with or without food, depending on the patient's and doctor's preference [2].

Yogurt, on the other hand, is a nutritious food that can be incorporated into a balanced diet. It contains probiotics, which can be beneficial for gut health [3].

However, the interaction between Lipitor and yogurt is not well-studied. There's no evidence to suggest that taking Lipitor with yogurt enhances or reduces its effectiveness or causes any adverse effects.

It's always recommended to consult with a healthcare provider or pharmacist for personalized advice regarding medication administration, including the timing and potential interactions with food [4].
