An adaptogen researched for resilience to physical and mental fatigue.
Rhodiola is an adaptogenic herb studied for its role in fatigue resistance, both physical and mental, rather than providing a direct stimulant effect.
It's commonly paired with other performance-oriented ingredients for this reason, supporting the body's capacity to handle stress rather than acting as an immediate energy source.
Its evidence base, while real, is smaller in scale than some of the more heavily studied ingredients here, like ginseng.
