5-HTP (hydroxytryptophan) is a pure natural herbal formula that is extracted from the seeds of West African pharmaceutical plants. It can improve sleep, help suppress appetite, make the body consume less carbohydrates, and reduce stress hormones, thereby suppressing appetite and thus achieving weight loss. It does not contain some undesirable side effects, including dry mouth, anxiety and loss of libido. It is the best substitute for anti-depressant prescription drugs and is widely used as an over-the-counter drug in many countries abroad.
