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.
