Functional B2 deficiency, also known as riboflavin transporter deficiency, is a rare genetic disorder affecting how the body absorbs and uses vitamin B2. Unlike a typical dietary deficiency, where a person simply doesn't consume enough riboflavin, a functional deficiency involves underlying issues with the body's metabolic processes or transport mechanisms. This means that even with sufficient dietary intake, the body cannot effectively utilize the nutrient, leading to severe health consequences if left untreated.

An estimated 6% of Americans are deficient in vitamin B12 alone, highlighting widespread issues with nutrient uptake. Learning how to enhance vitamin B absorption is critical for maintaining overall health, energy levels, and neurological function. This comprehensive guide provides practical strategies to optimize your body's use of B vitamins from both food and supplements.
