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 degenerative problems.
The Russian herb rhodiola (Rhodiola rosea) has demonstrated a remarkable ability to support cellular energy metabolism. Rhodiola promotes higher levels of adenosinetriphosphate (ATP) and creatine phosphate (CP) in the cellular power plants known as the mitochondria, thus providing more of the energy molecules needed to perform many daily activities.60
In a human clinical trial, rhodiola aided exercise endurance after just a single dose.61 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.62 A more recent clinical trial found that Rhodiola rosea significantly improves physical and cognitive deficiencies.63
Unlike many Rhodiola supplements on the market today, Life Extension’s Rhodiola Extract uses only the authentic Rhodiola rosea species and is standardized to contain the proven 3:1 ratio of 3% rosavins and 1% salidrosides, matching the concentrations of active adaptogens used in clinical trials. |
