 A recent Danish study observed that several other studies have recorded evidence of vitamin C deficiency as a high risk factor for heart disease. This study's conclusion was to merely propose a protocol for further study, ensuring the randomized double-blind approach for 'science based evidence.' This study's proposal was recorded by PubMed in March, 2013 as 'Does vitamin C deficiency increase lifestyle-associated vascular disease progression? - Evidence based on experimental and clinical studies.' (1-1a) This has already been worked out by orthomolecular and holistic health practitioners for well over a half century. But orthomolecular (mega-dose nutritional supplementation) is a bastard child of mainstream medicine. It is ignored even though most of the practitioners are certified MDs. A synopsis of ascorbic acid C for heart health Most of the vitamin C research for therapeutic purposes has been with ascorbic acid, which now more than ever is vilified as a synthetic toxin. Later in this article, some foods high in vitamin C will be listed. For now , consider that the Vitamin C Foundation the The Journal of Orthomolecular Medicine , and OrthoMed.org all firmly disagree. Why they disagree is explained point by point in a pdf. (2) Their disagreement is not theoretical or speculative. There have been several thousand cures of polio, cancer, and other diseases using mega-dose ascorbic acid. There is a history of successful ascorbic acid treatments curing the incurable, all ignored by the medical mafia. (3) Hundreds of comatose patients were led from death's door dramatically when mega-dose IV vitamin C or oral liposomal vitamin C were introduced. They used pharmaceutical grade ascorbic acid. Here's one very dramatic example featured by New Zealand's 60 Minutes TV News ( http://www.youtube.com/watch?v=VrhkoFcOMII ). Liposomal C is the new kid on the block. It can be taken orally and requires less ascorbic acid because it directs 90 percent of the vitamin C into cells instead of IV C's 20 percent cellular saturation ( http://www.selfnews.com/034591_vitamin_C_mega-dose_healing.html ). Pharmaceutical grade ascorbic acid is available online as a Vitamin C Foundation endorsed China-free, GMO-free ascorbic acid from Europe. It's pricier than the corn based stuff from China, and it's not used in most supplements that contain vitamin C as ascorbic acid because it's not cheap enough. Toronto physician William McCormick, MD, had investigated heart disease's relationship to vitamin C deficiency 20 years before two-time Nobel Prize winner Linus Pauling started his heart health research. Dr. McCormick's research led to the current IV mega-dose vitamin C applications of up to 100 grams daily for several diseases, including cancer. (3) During the 1980s, Linus Pauling tested high doses of ascorbic acid with the affordable amino acid lysine to reverse atherosclerosis (clogged arteries). This joint effort removes plaque and boosts collagen to restore the interior vessel walls endothelium's (thin skin layer) strength and elasticity. (4) Food sources for vitamin C Unlike most other mammals, humans don't create their own vitamin C. So it must be constantly taken in to avoid deficiency. Linus Pauling recommended using as many food sources as possible to obtain vitamin C with complete nutritive co-factors. Here are some choices: (5) Lemon or lime warm unsweetened water first thing in the morning Citrus fruits, try to include the pulp and some of the white stuff under the fruit's skin ( http://www.selfnews.com ). Potatoes, eat the skin Berries, any kind, fresh and organic Green veggies of all types, raw or lightly steamed Tomatoes and tomato sauces Spinach, raw in salad Melons of all types Vitamin C's fame has been recently eclipsed by other supplements, but its importance remains the same.
