Description
The Russian herb rhodiola (Rhodiola rosea) has demonstrated a remarkable ability to support cellular energy metabolism. Rhodiola promotes higher levels of adenosine triphosphate (ATP) in the cellular power plants known as the mitochondria, thus providing more of the energy molecules needed to perform many daily activities.135
A common complaint among older adults is loss of physical and mental energy. As people age, their cells' ability to produce energy is diminished. Many scientists believe that cellular energy deficit is a critical factor in the onset of many problems. In a human clinical trial, rhodiola aided exercise endurance after just a single dose.136 In a double-blind crossover human trial, rhodiola increased several measures of mental performance, including associative thinking, short-term memory, concentration, calculation and speed of audiovisual perception.
Statistically significant improvements were reported after just two weeks of supplementation.137 More recent clinical trials have found that Rhodiola rosea significantly improves physical and cognitive function.138-141 Unlike many Rhodiola supplements on the market today, Life Extension’s Rhodiola Extract uses only the authentic Rhodiola rosea species and is standardized 3% rosavins and NLT 1% salidrosides, matching the concentrations of active adaptogens used in clinical trials.
