Riboflavin Helps Turn Your Food Into Cellular Energy
Riboflavin, or vitamin B2, plays a critical role in energy metabolism by helping your body convert carbohydrates, fats, and proteins from food into usable cellular energy. It works by forming coenzymes that are essential for these metabolic pathways. Naturally present in foods like milk, eggs, and leafy greens, riboflavin supports the processes that keep you energized throughout the day.
