Rhodiola (typically Rhodiola rosea) has been investigated in scientific studies for its adaptogenic properties, including its potential effects on the mitochondria, which are the energy-producing organelles in cells. Preclinical research (cell and animal studies) suggests that Rhodiola and its main constituents (such as salidroside and rosavin) may help to enhance mitochondrial function. Mechanisms proposed include increased mitochondrial biogenesis, improved efficiency of the electron transport chain, and protection against oxidative stress. For example, studies have shown that Rhodiola extracts can increase ATP production and reduce markers of mitochondrial damage under stress conditions.

In humans, there is limited but promising evidence. Some clinical trials report that Rhodiola supplementation may reduce fatigue and improve exercise performance, outcomes that are suggestive (though not definitive) of improved cellular energy metabolism. However, direct measurement of mitochondrial function in human studies is rare, and most evidence remains indirect.

Overall, while there is scientific interest and some supportive data—particularly from laboratory and animal studies—the evidence in humans is preliminary. The use of Rhodiola to support mitochondrial health is therefore supported by a moderate level of scientific evidence, but more rigorous research is needed to draw firm conclusions about efficacy in the context of mitochondrial function in humans.
