L-Tyrosine and Rhodiola Rosea, a synergy.
Rhodiola inhibits MAO and COMT, reducing dopamine/norepinephrine breakdown. L-tyrosine provides the precursor. Together they increase catecholamine availability.

Synergy
What is happening. Rhodiola inhibits MAO and COMT, reducing dopamine/norepinephrine breakdown. L-tyrosine provides the precursor. Together they increase catecholamine availability.
Mechanism. Rhodiola's salidroside and rosavins inhibit MAO-A/B and COMT, reducing catecholamine degradation. L-tyrosine provides substrate for TH to increase catecholamine synthesis. Net increase in dopamine/NE signaling.
Recommendation. Effective focus and mental energy stack. Take in the morning for sustained cognitive performance.
