I can only speak from my own experience.
I had a blocked artery and was given Lipitor and similar, but soon found them to be destroying my muscles and nervous system. I flat stopped taking them, changed my diet to fresh fruits and vegetables, plus rice bran, omega-3, flax seed oil, lecithin, CQ10, folic acid (B9), plus lots of water and moderate exercise. From feeling like death warmed over, I pulled out of it and now (6-years later) feel healthier than I have in nearly 20 years.
Of the above combination, I don't know what did the most good, but I bet it was water, exercise and drastic change of diet to fresh fruits and vegetables. I'd stay away from the new GMO stuff, too.
Medical doctors are smart in the Rockefeller type medicine based on petroleum-based drugs and surgery, but know very little about health maintenance. Cures are anathema to Big Pharma, because they jeopardize profits. These days, I don't trust them at all.
My last primary care physician in the States told me I'd be on a purple pill for acid reflux for the rest of my life. Got rid of that with change of diet, but also digestive enzymes.
Don't overdo exercise. I found that an easy mistake. Take it slow and listen to your body, but keep upping the amount as comfortable. Listen to your body as you do it.
Hope this helps.
