We make energy in the presence of oxygen and this means that the body must be able to optimally take oxygen in through the breath, transport it around the body and then into the cells. Any breakdown in this supply chain can be a roadblock to the production of the body’s energy currency ATP and this can be experienced as fatigue. In this episode Anna discusses red flags and what tests, foods, supplements and general lifestyle practises may be helpful to optimise your body’s oxygenation and energy production.
