Magnesium

Magnesium is an essential mineral for human nutrition and is responsible for over 300 biochemical reactions. Magnesium is the fourth most abundant mineral in the body and is responsible for maintaining normal muscle and nerve function, supporting immune function, and keeping bones strong.

Magnesium is usually referred to as a “macromineral,” which means that our food must provide us with hundreds of milligrams of magnesium every day. (The other macrominerals that all humans must obtain from food are calcium, phosphorus, sodium, potassium, and chloride. Researchers estimate that the average person’s body contains about 25 grams of magnesium, and about half of that is in the bones.

Every organ in the body — especially the heart, muscles, and kidneys — needs the mineral magnesium. Most important, it activates enzymes, contributes to energy production and transport, and helps regulate calcium levels, as well as copper, zinc, potassium, vitamin D, and other important nutrients in the body. Magnesium is required for the proper growth and maintenance of bones, the contraction and relaxation of muscles, and the production of protein.

Magnesium benefits

Just a few of the benefits of magnesium include:

An easy way to remember foods that are good magnesium sources is to think fiber. Foods that are high in fiber are generally high in magnesium. Dietary magnesium is absorbed in the small intestines.

Magnesium Supplements

Nutrients should come primarily from foods however magnesium is one nutrient that most people are lacking in their daily diets, so supplementing it can be beneficial.

Magnesium is available in many forms. Recommended types include magnesium citrate, magnesium gluconate, and magnesium lactate, all of which are more easily absorbed into the body than other forms.
