Based on the information available, there is no direct evidence or scientific studies suggesting that Lipitor, a medication used to treat high cholesterol, can lower the potency of glucosamine. Glucosamine is a dietary supplement used for osteoarthritis, and its potency is typically associated with the dosage and the individual's response to the supplement [1].

Lipitor, also known as atorvastatin, works by reducing the production of cholesterol in the body, thereby helping to lower cholesterol levels in the blood [2]. There is no known interaction between atorvastatin and glucosamine that would suggest Lipitor could lower the potency of glucosamine [3].

However, it is always important to consult with a healthcare provider or pharmacist before starting any new supplement or medication, as individual responses can vary, and potential interactions may exist that are not well-documented [4].
