Also known as riboflavin, vitamin B2 plays a vital role in cellular growth and function and energy production. Although vitamin B2 is found in lean meats, organ meats, asparagus, and grain products, it can be difficult to satisfy your daily requirements through food sources alone. Adding The Vitamin Shoppe® brand Vitamin B2 100 MCG vegetable capsules to your supplement stack makes consuming your daily dose of B2 a breeze.
