A Canadian researchers team led by dr. GC Willis, found that heart diseases are caused by hidden forms of scurvy and chronic and can be cured with high doses of vitamin C without heart surgery and drug treatments costly and with effects devastating side in organic plan. But the process of healing cardiovascular disease with vitamin C is not approved by the medical institutions and the pharmaceutical industry, which earns billions of dollars in surgeries and drugs that are used in allopathic therapies for various cardiac diseases. Canadian scientist discovery was confirmed in the late 80 s by Dr. Linus Pauling, Nobel laureate, the most noted human of his time. The medical care developed by Dr. Pauling include vitamin C with added lysine (amino acid nutritional qualities, existing in most... plant and animal proteins) and it works cleanly, healing cardiopathy once thought were incurable. Dr. Pauling medical care records healing miracles coronary diseases. It had been identified back then that vitamin C deficiency within the body weakens human arteries by forming induration of the arteries plaques (infiltration of the walls of the artery and arteries with fat), that blocks blood circulation. This paper aims to spotlight the importance of vitamin C for the treatment and prevention of circulatory diseases especially. The daily minimum demand of vitamin C at tissues and cells level for a healthy person is: 75 mg/day women, 90 mg/day for men, 100 mg/day smokers. But always need a bigger tank because these amounts could reach all tissues and cells of a healthy organism: about 500-1000 mg/day. When the body is disturbed or ill, quantities required to repair cells, are much higher 5000-10000 mg/day.
