Maca and Panax Ginseng: What the Research Shows

By the SodaPower Editorial Team. Updated September 2026. Checked against the published Supplement Facts panel.

Quick answer: Maca raised reported sexual desire at 1.5 to 3 g a day in small trials without changing testosterone. Panax ginseng root shows modest, low-certainty effects on erectile function and fatigue.

Maca

In a 12-week trial, men taking 1.5 or 3 g of maca reported more desire from week 8, with testosterone unchanged (Gonzales 2002).

Panax ginseng

Reviews suggest a small effect on erectile function, with low-certainty evidence, mostly using root extracts. NCCIH notes ginseng may interact with blood thinners and diabetes medicine (NCCIH).
