A friend of mine asked if her dad can take the Cardio -C if he is on these medicines : aspirin, ramipril, rosuvastatin, bisoprolol, nitroglycerin (if needed). Thanks for your help and advice.
This is johnwen's domain, but I'll add what I think I know..
If you look at the early testimonials, heart patients were usually at the end of their ropes and on a myriad of drugs for their conditions. Almost everyone recovered quickly on Pauling's therapy - and they didn't stop taking their drugs (right away.) Everything in Cardio-C (e.g. vitamin C, lysine and proline) are nutrients necessary for life, and vitamin C and lysine are essential - meaning you must have them in the diet to survive. The only issue is dosage, but, again, from the history, the Pauling Therapy (e.g. Cardio-C) only makes very sick people well.
Most people quickly wean any drugs, but this can be problematic since most heart patients don't discuss what they are doing with their doctors. I think usually the better test results are all that is needed to reduce the drug prescriptions. (Docs naturally figure that their treatments are working... etc.)
