What does biotin interfere with? Excess biotin in the blood from supplements can block that binding and the substance won’t be measured accurately. Most of the published research on biotin interference covers hormone tests, such as parathyroid hormone (PTH), thyroid stimulating hormone (TSH), T4 and T3 tests, as well as tests for troponin.
Does biotin work with other vitamins? Biotin is generally safe to combine with most vitamins; however, there’s little research to support its use if you don’t have a deficiency.
What should I avoid taking with biotin? Biotin has no known adverse interactions with any medications, supplements, food, or beverages. Unless directed by your doctor, continue your regular diet and activities.
