Magnesium is one of the minerals we have the most of in the body (in fact it’s the fourth most common mineral), and is important for several functions of a healthy body – not least for the absorption of vitamin D.
Magnesium is found in all types of cells and supports a variety of bodily functions and processes. For example, magnesium acts as a coenzyme in the burning of carbohydrates and proteins, and contributes to the absorption of other minerals such as calcium, phosphorus and sodium. Magnesium also contains certain enzymes that are needed in order for B, C and E vitamins to be absorbed properly.
Magnesium plays a part in over 300 different enzyme reactions in the body, which are primarily about producing and taking care of energy. In other words, magnesium is one of our most important minerals and nutrients. Below you can read more about the benefits of magnesium:
Magnesium assists in the activation of vitamin D, which helps regulate levels of calcium and phosphate in the body. Consuming large amounts of vitamin D without consuming enough magnesium can therefore cause the body’s levels of calcium and phosphate to increase and to not be absorbed into the skeleton where they belong. The calcium can then end up in the vessel walls instead, which increases the risk of calcifications in the blood vessels.
In addition, the enzymes that burn vitamin D also require magnesium in order to fulfil their purpose properly. The vitamin D you consume can therefore not be utilised by the body if you have not ingested sufficient amounts of magnesium.
Magnesium deficiency is relatively uncommon but can occur in connection with certain diseases and in cases of restricted diets. Symptoms of magnesium deficiency include muscle cramps, difficulty sleeping, high blood pressure and more subtle signs such as cravings for dark chocolate and difficulty relaxing. Too much magnesium can result in diarrhea.
The daily recommended intake is 280 milligrams for women and 350 milligrams for men. Magnesium is found in many types of natural unprocessed raw produce (see list below), but the amount of magnesium in these foods has decreased over time due to the increased use of pesticides and fertilisers. In addition, the magnesium you consume is used up faster if you consume a lot of sugar, since it takes as many as 54 magnesium molecules to process a single sugar molecule, and the same goes for very fatty and refined foods.

Dark chocolate (high cocoa content)
