Rhodiola helps improve oxygen transfer from lungs to red blood cells. It is a Himalayan root used by the Sherpa people to “adapt” to the stress of living and working at high altitudes. Even today, Sherpa climbers chew on rhodiola for an energy and endurance boost when helping mountaineers scale Mt. Everest.
One mechanism for rhodiola’s anti-fatigue effects is an enhancement of oxygen efficiency — with subjects living at high altitude (5,380 meters) showing a beneficial effect of rhodiola supplementation on blood oxygen levels, time to exhaustion, VO2 peak, and pulmonary ventilation during endurance exercise.
Dosage: 50-300mg (standardized to 5-6% rosavins)
