Malic acid

Detailed Product Description

 

Malic acid is both derived from food sources and synthesized in the body through the citric acid (Krebs) cycle. Its importance to the production of energy in the body during both aerobic and anaerobic conditions is well established. Under aerobic conditions, the oxidation of malate to oxaloacetate provides reducing equivalents to the mitochondria through the malate-aspartate redox shuttle. During anaerobic conditions, where a buildup of excess of reducing equivalents inhibits glycolysis, malic acids simultaneous reduction to succinate and oxidation to oxaloacetate is capable of removing the accumulating reducing equivalents. This allows malic acid to reverse hypoxias inhibition of glycolysis and energy production. This may allow malic acid to improve energy production in FM, reversing the negative effect of the relative hypoxia that has been found in these patients.

In addition, malic acid is the only metabolite of the citric acid cycle positively correlated with physical activity. It has also been demonstrated that exercise-induced mitochondrial respiration is associated with an accumulation of malic acid. In humans, endurance training is associated with a significant increase in the enzymes involved with malic acid metabolism.
