According to the study, The U.S. Food and Drug Administration (FDA) issued a warning in 2017 that “high doses” of the supplement, defined as one milligram or more, could result in inaccurate lab testing. As the study shows, this amount of Biotin can produce inaccurately low results in blood tests for troponin, a protein group that can signal a heart attack or heart damage.ae0fcc31ae342fd3a1346ebb1f342fcb Anne Thorndike, MD, chair of the American Heart Association’s nutrition committee, discussed the findings with U.S. New & World Report. “If you’re taking high-dose Biotin and you have a heart attack, there’s a good chance you might not be diagnosed correctly,” she warned. The study also assessed just how common high doses of Biotin are in popular products. Virtually unheard-of before the year 2000, the study’s analysis revealed that today, roughly three percent of adults consume high doses of the over-the-counter supplement. Perhaps even more alarmingly, certain demographics take the supplement at much higher rates than others, putting them at serious risk. Danni Li, PhD, an associate professor of laboratory medicine and pathology at the University of Minnesota and leader of the study, explained that over seven percent of women aged 60 and above currently take high daily doses of Biotin. Two percent of women that age take a whopping daily dose five milligrams or more. For reference, the recommended daily intake of the vitamin is just 30 micrograms, or 0.03 milligrams. That’s why it’s best to get the benefits of Biotin from natural dietary sources. Eating meat, eggs, fish, nuts, and certain vegetables provides the same health benefits as the supplement—without the added risk of overdoing the dosage.
