Tyrosine is used in the nervous system to make a class of neurotransmitters called catecholamines: dopamine, norepinephrine and epinephrine. Epinephrine, made from tyrosine in the adrenal medulla, functions as a neurohormone and is known as adrenaline.\u003c\/p\u003e\n\u003cp\u003eIn addition to acting as a neurotransmitter that supports healthy mood and sleep, norepinephrine is now known to protect brain cells by promoting a healthy inflammatory response, inhibiting oxidative stress and supporting healthy neuronal growth and connectivity.\u003c\/p\u003e\n\u003cp\u003eDopamine, though long associated with more primal aspects of brain function linking behaviors to rewards, is recognized now as a mediator of higher-order cognitive capacities.The diminishment in brain catecholamine production that occurs with aging may be a contributing factor in normal age-related cognitive decline. Providing catecholamine precursors can help support healthy cognitive function. The enzyme that catalyzes the conversion of tyrosine to dopamine may work more efficiently if its co-factors (vitamins B6 and C) are included.\u003c\/p\u003e","brand":"Life Extension","offers":[{"title":"100 Veg.
