Maca Root, Eleuthero Root, Astragalus Root, Panax Ginseng and L-Tyrosine.
This group leans on adaptogenic botanicals — plants traditionally used to support the body's response to physical and mental stress — rather than direct stimulants.
Maca, eleuthero (sometimes called Siberian ginseng) and panax ginseng all carry long traditional-use histories for energy and stamina, with a growing modern research base of varying strength behind each.
L-Tyrosine is an amino acid precursor to dopamine and norepinephrine, included here for its role in supporting mental alertness, particularly under stress or fatigue.
