After reviewing the sources provided, there is no indication that there is a specific time to take Lipitor before yoga. Lipitor is a medication used to lower cholesterol levels in the body, and the time of day it is taken may vary depending on the individual's needs and schedule. According to Drug Patent Watch [1], Lipitor is typically taken once a day, with or without food, at the same time each day. However, the timing of when to take Lipitor may also depend on other medications the individual is taking or if they have any underlying health conditions.

In terms of the relationship between Lipitor and yoga, the sources do not provide any information about a specific time to take Lipitor before practicing yoga. However, a study published in the National Center for Biotechnology Information [2] suggests that practicing yoga may have a positive effect on cholesterol levels, which could potentially complement the use of Lipitor.

It is important to note that Lipitor has been the subject of lawsuits [3] due to potential side effects, such as an increased risk of developing type 2 diabetes. Therefore, it is recommended that individuals consult with their healthcare provider before starting or changing the timing of their Lipitor regimen, especially if they plan to incorporate yoga or other physical activities into their routine.
