Riboflavin is vitamin B-2, which is a water-soluble vitamin used by the body to produce red blood cells, derive energy from carbohydrates and increase cell turnover. Excess amounts of water-soluble vitamins are excreted from the body and are not stored. Therefore, riboflavin must be consumed daily to avoid deficiency. Males should consume 1.3 mg of riboflavin per day, and females should consume 1.1 mg of riboflavin per day, according to "Contemporary Nutrition."
Step 1
Locate the nutrition facts on the back on the container of tablets.
Step 2
Locate the serving size. This information is listed in the upper portion of the nutrition facts table. Often, one tablet is one serving, but that is not always the case. Also locate the amount of riboflavin listed on the nutrition facts table.
Step 3
Divide the number of tablets in one serving into the amount of riboflavin in one serving to determine how much riboflavin is in each tablet. For example, if the nutrition facts state that one serving is two tablets and there is 100 mg of riboflavin in each serving, you can calculate that each tablet contains 50 mg of riboflavin.
