According to the sources provided, the recommended maximum daily dose of Advil (ibuprofen) for adults is 1200 mg per day, which is equivalent to six 200 mg tablets. However, it is important to note that this maximum dose should not be taken all at once, but rather spread out over the course of the day. It is also recommended to take the lowest effective dose for the shortest duration possible to minimize the risk of side effects.

It is important to consult with a healthcare provider before taking Advil or any other medication, especially if you have any underlying medical conditions or are taking other medications. Additionally, it is important to follow the instructions on the label and not exceed the recommended dose.
