                                The body's Recommended Dietary Allowance for riboflavin (vitamin B2) for adults is only about 1.3 mg for men and 1.1 mg for women, yet supplements containing 100 mg or more are common. This significant difference often causes concern regarding the safety and necessity of taking such a high dose.
