Studies Show Vitamin C Can Reduce Duration And Severity Of Colds

The human body cannot produce it’s own vitamin C. Vitamin C is water-soluble which means it is quickly excreted. Aging individuals tend to have even lower levels of vitamin C. That is why it is necessary to supplement daily with vitamin C to ensure the proper function of vital bodily functions including the immune system. During times of inflammation or infection the immune system’s demand for vitamin C increases 100-fold.

Studies have shown that 1000 mg of vitamin C daily can reduce the duration and severity of the common cold, and even reduce the chance of developing a cold. In two separate studies “absence from school and work was reduced by 14-21% per episode.” Additional studies found “common cold incidence decreased by on average 50%, and in four trials of British males common cold incidence decreased by on average 30% in the vitamin C groups.”

Without regular supplementation of vitamin C levels can quickly drop. With inadequate vitamin C cells are less able to detect and destroy invading organisms or harmful cells, leaving one vulnerable to dangerous infections.
