The first concept was to require recommended daily allowance (RDA) of vitamins to A level that might prevent acute deficiency diseases just like the Sailor’s disease scurvy. 

These are the standards by which RDA’s were created. However, in recent years, research has shown that Vitamins taken in higher doses can prevent sever chronic diseases like cancer and heart condition . 

A debate still rages, but there's a plethora of research being done on vitamin A , C, E, the antioxidant vitamins. 

A National Institute of Health clinical test involving people at high risk of developing advanced stages of Age-related degeneration (AMD), showed that patients’ risk decreased by 25 percent when treated with high doses of antioxidant vitamins and zinc. 

Another study at the middle for Disease Control and Prevention (CDC) in Atlanta showed that taking vitamin E along side multivitamins reduced risk from stroke and heart illness. 

Among patients who took the mixture , mortality risk decreased by 15 percent for these two diseases. 

This September, the National Institutes of Health (NIH) concluded a study investigating the connection between vitamin C and cancer, suggesting that vitamin C may fight cancer. 

They found, during a laboratory setting, that prime doses of vitamin C injected directly into the bloodstream killed cancer cells. 

Though the present RDA for vitamin C is stuck at 60 mg, many researchers suggest that raising the RDA to between 100 and 200 mg would be an excellent way for people to urge the antioxidants that they have to take care of overall well being. take care when purchasing vitamins and supplements though. 

Research has shown that whole food vitamins, or vitamins with their co-factors, are far more effective than isolated nutrients. 

Nutrition may be a complex process of thousands of chemical reactions within our bodies. 

Vitamins are always better within the ir wild - in the foods we eat. Supplements should never be utilized in place of a poor diet. 

The smart choice is to seem for whole food vitamins to supplement an already good diet for the days you cannot get everything you would like at dinner time .
