Why magnesium is a miracle mineral for runners

Why do runners need magnesium?

Magnesium is required for energy production, muscle recovery and bone development. It protects us from oxidative damage, which is increased as a result of the energy produced when we run. It also supports resistance to mental stress and acts as a smooth-muscle relaxant. Optimal magnesium levels can help reduce tiredness, maintain normal blood pressure and protect your DNA. Magnesium might also help reduce the accumulation of lactic acid during hard sessions.

How can I tell if I’m deficient?

Fatigue and muscle spasms or cramps are among the symptoms; but these can have many different causes. Low magnesium levels over a long period can compromise your health in various ways and even lead to osteoporosis. Those typically at risk are people with gastrointestinal diseases or type 2 diabetes, elderly people and those who aren’t consuming optimal amounts in their diet.

How can I boost my levels?

Before you even think about supplements, try to increase the amount of magnesium-rich foods in your diet. The recommended daily intake for adults is between 300mg and 400mg per day. Include leafy greens in your diet – they are rich in magnesium. Add a big handful of spinach to your post-run smoothie, or into a salad. Kale is also high in magnesium, while some nuts and seeds are heaving with the stuff.

    How can I supplement magnesium?

    While we might naturally turn to a pill, in some cases the digestive system can fail to absorb nutrients efficiently. Skin-absorbed supplements are well worth considering; these are available in forms such as body butters, oils and flakes that you can add to your bath. A postrun magnesium bath is a great way to help soothe both muscles and mind.
