Shallow breathing makes the body produce lactic acid to get its energy. Some consequences are muscle pains and anxiety. One solution is extra calcium, which binds with lactic acid, neutralizing its effects by forming calcium lactate, according to Pitts, McClure, and Reich. Under stress, my PPS fatigue levels go up and with them come anxiety, stiffness, pain and fatigue. Lactic acid energy generates about 40 kilocalories of energy per ATP molecule.
Lactic acid is one way of keeping all the cells, brain and muscle, going.
However, under rich oxygen conditions, the body kicks into its most efficient gear of energy production, the oxidation, or oxygen pathway of protein, carbohydrate, or fatty acid metabolism. Calcium and magnesium combine with lactic acid, neutralizing the negative effect of excess lactic acid, normalizing pH, and normalizing breathing for asthma, emotional disturbances, and restoring the ill health of people in many disease conditions. Hyde, Cheney, and Goldstein have used it in their practice with CFS to improve energy and reduce pain. The reason for greater energy is made clear by Lehninger. It doesn't neutralize lactic acid build-up directly.
