People taking maois should avoid foods and supplements containing tyrosine. In sum, we observed higher baseline plasma tyrosine concentrations in older compared with young adults. Research confirms that tyrosine is actively transported across the blood-brain barrier where it increases dopamine, norepinephrine, and epinephrine in the brain.
