Dr. Sponaugle Says:
"Dopamine naturally converts to norepinephrine, which then converts to epineprine (pure adrenaline). These three brain chemicals are known as catecholamines. The enzyme dopamine hydroxylase converts dopamine into norepinephrine in absence of copper deficiency and vitamin C deficiency. Copper deficiency can occur secondary to excessive zinc intake, or malabsorption of copper."
