Review: Improve clogged arterite! - Product on US market years ago faded out - Vitacore. The US proponent was Dr. Linus Pauling who passed on. He had a business partner in Europe who still sells Vitacore. Here in US you can get same thing from desertcart or Vitamin Shoppee - discount catalog. Proline + Lysine pills,- BUT HAS 1000MG of Vit C. See back label. SAME AS VITACORE. It was also originally available as orange powder drink . US Patented and tested as OK and works. Think of the water pot on stove with lime caked up . Add water and vinegar without stirring. After a while the pot is cleaner. The Proline + Lysine erodes away very slowly the Plaque build up in arteries from Cholesterol and fat. The autonomic process in body has no personal control. It constantly heals and adds collagen to arteries . If not enough collagen, process uses fat and cholesterol on surface of arteries. Poor diet. Takes a few weeks to feel better. A start of clearing on medial scan within 3 months. Full process takes a year constantly on pills. The Vit C allows body to MAKE collagen as well as from the food. So now you know. There was a movie years ago with Harrison Ford that was a put down on such a product. Producers of " The Fugitive" made it out as non worthy - they called it Provassic.
Review: Great Stuff! - I've been taking this stuff almost two years. They are horse pills, but easy enough to swallow. I take two in the morning, and two in the evening. I began using it after having an ischemic stroke (cholesterol blockage). After a year, my doc took me off the statin, and my LDL is still going down. I've had knee and hip issues for years...getting out of a seat was not fun, squatting was impossible, even walking was painful. I now, simply stand up from a chair, sofa, etc; I can do squats with/without weights again, and no issues/pain walking. I've even started running again. My wife's sister and a couple of friends have tried it, and report similar results. It does take a couple months to start noticing improvement, so bear with it.

### ⭐⭐⭐⭐ Big Pill
*by K***T on February 13, 2025*

These are large pills but I have a pill splitter since split easy to take. Purchased accidentally but took them anyway and I do notice a slight difference in skin. Am getting another bottle to keep it up n see if more change happens.
