Rhodiola rosea, also known as golden root, is well known for its health benefits in humans, such as decreasing fatigue, ; boosting mood, memory and stamina; and preventing .

The herb is grown in cold climates at high elevations, and has been used for centuries by Scandinavians and Russians to reduce stress. It’s also thought to have antioxidant properties.

The current research carried out by determined that the extract increased the .”We found that Rhodiola actually increases lifespan on top of that of ,” Mahtab Jafari, one of the , said. “It demonstrates that Rhodiola can act even in individuals who are already long-lived and healthy. This is quite unlike , which appears to only act in overfed or unhealthy individuals.”

The researchers proved this by putting flies on a calorie-restricted diet. It has been shown that flies live longer when the amount of yeast they consume is decreased. Jafari and Schriner expected that if Rhodiola functioned in the same manner as , it would not work in these flies. But it did. They also tested Rhodiola in flies in which the of had been genetically inactivated. It still worked.

Not only did Rhodiola improve lifespan an average of 24 percent in both sexes and multiple strains of flies, but it also delayed the loss of physical performance in flies as they aged and even extended the lives of old flies. Jafari’s group previously had shown that the extract decreased the natural production of reactive oxygen species molecules in the fly mitochondria and protected both flies and against oxidative stress.
