Day by day, an estimated 50 percent of
Americans take a supplement or two. For example, many people take a few
ascorbic acid tablets to add to their resistance to the common cold. The main
reason for taking dietary supplements is to add to what you normally get from
your food. This is necessary because people have unbalanced diets at times, and
these dietary supplements provide an effective way to meet the recommended
daily allowance of vitamins and nutrients.
