Vitamin D3 – A study in the Virology Journal (February 25, 2008) states, “2000 I.U. of Vitamin D3 per day abolished the seasonality of influenza and dramatically reduced its self reported incidence.” Vitamin D3 is crucial to our body’s initial defense (called innate immunity) against infections.
Vitamin D3 – 2000 I.U.s has also been found to reduce the risk of cancer by 50% (Annals of Epidemiology July 2009 pg. 468-483) A brief quote from the study reads as follows:
“Daily doses of 2000 I.U.s of Vitamin D3 would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial. Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal or prostate cancer by half. There are no unreasonable risks from intake of 2000 I.U. per day of vitamin D3. The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium.
Vitamin C – “In a controlled trial of over 700 students, the vitamin C-treated test group (showing flu/cold symptoms) given 1000 mg every hour for the first six hours (and three times daily afterwards) vs. the control population who were treated with pain relievers and decongestants showed an 85% reduction in symptoms. Vitamin C “administered before or after the appearance of cold and flu symptoms relieved and prevented the symptoms in the test population compared with the control group.” (Source: Gorton HC.
