What is the percent daily value of riboflavin?

The percent daily value of riboflavin, often found on nutritional labels, indicates the percentage of the daily recommended intake of this vitamin that a serving of food provides. Riboflavin, also known as vitamin B2, is vital for energy production, cellular function, and the metabolism of fats, drugs, and steroids.

In the context of daily requirements, for adults, the recommended daily allowance (RDA) for riboflavin is generally around 1.3 mg for men and 1.1 mg for women. The percent daily value is calculated based on these recommendations, with 100% typically representing the daily target intake. The value of 19% signifies that a food serving provides a significant portion of the daily requirement, making it a beneficial nutrient in the diet.

Since riboflavin is essential for various bodily functions, the percentage reflects its importance in promoting overall health. A daily intake near this percentage indicates a good source of riboflavin, supporting energy metabolism and various other physiological roles.
