D-Phenylalanine, USP

According to my research I've come to the conclusion that D-Phenylalanine is a safe alternative to aspirin, tylenol, ibuprofen and opiates for acute and/or chronic pain. D-Phenylalanine is non-addictive and will not upset the stomach. By Bonnie O'Sullivan, Editor, The Road To Health Newsletter
