Some of the most common nutrients are depleted by commonly used medications. As a cardiologist, the use of statin drugs to lower cholesterol has been reported for years to deplete a cardiac supplement called Coenzyme Q10. I recommend any patient taking a statin drugs consume 60 - 100 mg of coenzyme Q10.
I also use many anti hypertensive or blood pressure lowering drugs. I find some of the drugs in these classes lower zinc, potassium , magnesium and folic acid. These are important nutrients for the body.
One class of drugs , the proton pump inhibitors for acid refllux are prescribed way too often and used for many years. This class of drugs deplete B12 and folic acid in addition to magnesium and vitamin C
I feel patients should know what kinds of drugs they are taking and what side effects each might have. The above is just a small sample of some drugs and their side effects towards nutrition and supplements
