Therefore, pregnant women should not consume biotin supplements unless prescribed by the doctor.
An acne break out in the jawline is the common side effect caused by biotin. The skin becomes clear once the intake of the supplement is stopped. This skin problem can be reduced by lowering the dose of biotin and drinking large amounts of water.
