Synergy
What is happening. Vitamin C Liposomal is a cofactor for dopamine beta-hydroxylase, which converts dopamine (from tyrosine) to norepinephrine.
Mechanism. After L-tyrosine → L-DOPA → dopamine, dopamine beta-hydroxylase (DBH) converts dopamine to norepinephrine. DBH requires ascorbate as an electron donor for this copper-dependent reaction.
Recommendation. Take vitamin C with L-tyrosine to support the full catecholamine synthesis pathway from dopamine to norepinephrine.
