Consuming large doses of riboflavin (vitamin B2) is generally considered safe and nontoxic, as excess amounts are excreted in the urine. However, some individuals may experience side effects such as diarrhea or yellow discoloration of the urine if they take excessively high doses. It is always recommended to follow the recommended daily intake levels for vitamins and minerals unless directed otherwise by a healthcare professional.
