Standard Process Neurotrophin helps the nervous system that provides much of the control functions for the body. In general, the nervous system governs the rapid activities of the body, such as muscle contractions, constantly changing visceral events, and even the rates of secretion for some of the endocrine glands. Neurotrophin PMG contains Protomorphogen extracts which are uniquely derived nucleoprotein-mineral extracts that support cellular health. Porcine brain PMG extract helps maintain the nervous system in a good state of repair to support healthy brain function.
