Recognize High Biotin Side Effects. Biotin is a vitamin sold under a variety of names such as Biotina, Vitamin H, Vitamin B7 or Coenzyme R. Although biotin is present in many foods such as nuts and legumes, people may need to take biotin supplements if they have been diagnosed with biotin deficiency. Low biotin side effects include hair loss, inflamed eyes and a red skin rash. But taking too much biotin can lead to high biotin side effects. It is very rare for anyone to suffer from an overdose of biotin since the body normally flushes out any excess biotin in urine. But reports of biotic toxicity have been reported in people taking mega doses that also take doses of pantothenic acid.
