6 Dangerous Side Effects Of Biotin You Need To Know!

Like we stated before, some people can be allergic to biotin – this will most likely happen to people who are allergic to Vitamin B12 or cobalt. A skin rash can be one of the symptoms, but some people can experience nausea and swelling of the throat and face.

This type of allergic reaction can be managed, but if the issue is not addressed by a medical professional, it can also become quite dangerous. To avoid a situation like this, try not to take biotin in large doses and try to see how your body reacts to that change. Either way, it is always good to check with your doctor to be safe.
