Foods high in Riboflavin

Riboflavin is one of the B vitamins the body uses constantly to release energy from the food you eat and to support normal red blood cell production, and because it isn't stored in meaningful amounts, regular intake matters more than occasional large doses. Isolated riboflavin deficiency is uncommon today in the United States, largely thanks to fortified grains and widespread dairy and egg consumption, so most people don't need to actively seek it out. Riboflavin deficiency also rarely shows up alone — it tends to accompany broader dietary gaps affecting several B vitamins at once, which is one reason a varied diet matters more than chasing any single nutrient. Riboflavin is also sensitive to light, so foods and drinks that contain it, like milk, are typically packaged in opaque containers to protect it. The list below ranks foods and ingredients by measured riboflavin content per the amount tested. Organ meats such as liver and fortified products cluster at the top because they're especially concentrated sources by weight, while dairy, eggs, almonds, and salmon further down the list better reflect what typically shows up in an everyday diet. Comparing a food's rank here to how much of it people realistically eat in one sitting is a more useful way to judge its practical contribution than the raw ranking alone.
