If you are new to taking this product please know that you might have a slight rash and red glow straight after you take it. This is nothing to be alarmed of if it goes away after about 1 hour, depending on your sensitivity to supplements. It usually subsides when you start working out due to blood flow and movement. Itching when you first start taking it is also normal. If the itching and redness persist over more than a day (which it honestly should not), then please contact us for further guidance or lessen your dosage.
