There are a few Facebook groups on the subject. I have good results with taking Beta Alanine during flares of COLD URTICARIA. It kills the itch and calms my skin…it is an OTC supplement typically used as a preworkout supplement. I take 750 mg every four hours as needed, which is a much lower dose then using it for preworkouts. If you take too much you can get a weird tingling felling on your skin…
