                                It is a fact that certain medications and supplements can cause stools to change color, and vitamins are no exception. But can vitamins cause light-colored stool, and when should you be concerned about this change? Occasional light-colored stool from supplements is generally not a cause for alarm, but persistent changes can signal a more serious underlying issue.
