How important is magnesium for athletes? 

Now coming to the importance of magnesium for athletes, studies have shown that the requirement of magnesium for an active person is much more than a sedentary person.

As you can quite deduce, magnesium plays numerous roles in the human body and various studies have shown that high levels of magnesium help in boosting muscle power, especially increasing the strength of the leg muscles. 

When we consume magnesium-rich foods or supplements, magnesium enters into our bloodstream and helps in lowering the lactate levels in the body. Lactate or lactic acid is a metabolite that is generally produced due to intense physical exercise. If lactate continues to build up in the muscles, then muscle performance gets limited and the person can get fatigued easily. 

How to exercise with proper magnesium?

Exercising without adequate levels of magnesium in the body also leads to excess oxygen consumption and an increase in heart rate. 

Magnesium plays a huge role in boosting the immune system and its function in the body is similar to that of an antioxidant and therefore helps in reducing the risk of getting injured during strenuous physical exercises. 

Deficiency of magnesium in athletes can lead to depletion in energy production, getting lethargic quickly, reduction in performance, and frequent episodes of muscles twitching and cramps.
