Vitamin B2 (Riboflavin) Deficiency : A Comprehensive Guide

Vitamin B2, also known as riboflavin, is one of the eight B vitamins that play a crucial role in maintaining human health. It is a water-soluble vitamin that helps the body break down carbohydrates, proteins, and fats to produce energy, and it allows oxygen to be used by the body. Riboflavin is also essential for the growth, development, and function of the cells in our body and helps in converting food into energy.
