The riboflavin content of foods or supplements is expressed in milligrams (mg).
The recommended dietary allowances (RDAs) for different life stages is based on the amount required for normal body reserves, urinary excretion of the vitamin, red blood cell content, as well as other, more complex factors.
To compensate for losses, pregnant and breastfeeding women should have a higher riboflavin intake.
Adults need between 1.1mg (women) and 1.3mg (men) of riboflavin per day. Roughly speaking, that’s the equivalent of two bowls of fortified breakfast cereal. Pregnant women need 1.4mg, and breastfeeding women need 1.6mg, per day.
