Riboflavin (Vitamin B2) may cause a bright yellow colour in your urine. This is completely normal and simply indicates that your body is absorbing the essential nutrients it needs.
We have included a meaningful dose of Riboflavin and other B vitamins, as many respected authorities recognize their important health benefits. These vitamins have been extensively studied and are safe, with no known toxicity at recommended levels.
As a water-soluble vitamin, any excess Riboflavin naturally passes through your system. Rest assured, your body takes in what it needs to support energy production and overall health before safely excreting the remainder.
