Magnesium before exercise doubles glucose availability and improves performance
Magnesium is a vital and often forgotten mineral in sports nutrition. Not only does magnesium help reduce the incidence of muscle spasms and cramps it also helps the heart maintain regular rhythm particularly when under stress.
Magnesium and Glucose: Glucose mobilization and utilization in the periphery and central nervous system are important during exercise and are responsible for exercise efficacy. Releasing these stores of glucose so it can be available for instant energy requirements can make all the difference when pushing your body to the limits.
Supplementation of Magnesium before exercise doubles glucose availability in the peripheral and central systems, and increased lactate clearance in the muscle during exercise.
