Why You Should Supplement With Magnesium

All our cells contain magnesium, and this macro-mineral plays an important role in over 600 enzymatic reactions.
A large number of people are not getting sufficient amounts, which is why it's important to supplement with magnesium.
We’ve rounded up some of its benefits and the reasons why it is essential to supplement with magnesium.

Magnesium plays an important role in energy creation, protein synthesis and in over 600 other enzymatic reactions. In short, it's essential for your body (1). Adult men need at least 400 mg of magnesium a day while adult women require at least 310 mg (2). Sadly, a large part of the population is not getting enough of it (3).

Foods like spinach and kale, nuts and seeds and a variety of other fruits and vegetables are excellent sources of magnesium. However, many of us have poor food choices and an imbalanced diet, often a result of our fast-paced culture and busy schedules. Thus, a lot of people find it hard to consume sufficient amounts of this macro-mineral. So, if you cannot eat enough magnesium-rich foods, then it’s best to supplement with magnesium. Here are the reasons why.

Why You Should Supplement With Magnesium

Your Body Needs Magnesium to Function

Firstly, every cell in your body contains magnesium. This macro-mineral is involved in a lot of your body’s major processes. This includes converting the food you eat into energy, repairing and creating DNA and RNA, and regulating your nervous system’s neurotransmitters. Additionally, it helps in managing your muscle movements — including your heart muscle cells — converting amino acids to proteins and so much more.

It May Help Enhance Exercise Performance

Magnesium plays an essential role in managing the body’s creation of energy and muscle function. Indeed, studies show that as activity level rises, the need for this macro-mineral also increases. Findings reveal that a supplement with magnesium has the potential to improve physical performance (14).

It Helps Improve Bone Health

Sufficient magnesium intake is essential for strong bones. Yes, they need calcium too. However, they require more than just that. First, your body needs vitamin D to properly absorb the calcium that you consume. You can get vitamin D from the sun, supplements and even from foods like tuna and salmon. However, the sunshine vitamin requires sufficient amounts of magnesium to be properly metabolized. Therefore, you need magnesium for healthy bones. Otherwise, your body will not be able to absorb the calcium that your bones need (15).
