Riboflavin, also known as Vitamin B2, is a water-soluble vitamin that plays an important role in energy production and metabolism. It is involved in many cellular processes, including the metabolism of fats, carbohydrates, and proteins, as well as the production of red blood cells.
Riboflavin is commonly used as an ingredient in protein powders due to its ability to support energy metabolism, which is important for athletes and individuals who engage in regular exercise. It also has antioxidant properties and helps to protect against oxidative stress.
In terms of safety, riboflavin is generally considered safe when consumed in recommended amounts.
