Magnesium is an essential mineral crucial for many physiological processes in the body. It plays a role as a cofactor in more than 300 enzyme systems that regulate a range of biochemical reactions including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation¹. Magnesium is also integral for energy production, DNA and RNA synthesis, and bone structural development².

Here are some key points about magnesium:

1. Sources: Magnesium is naturally present in various foods such as green leafy vegetables, unrefined grains, legumes, beans, nuts, and seeds. It is also available as a dietary supplement and in some medicines (like laxatives and antacids)³.

2. Bodily Functions: It is necessary for energy production, oxidative phosphorylation, and glycolysis. Magnesium aids in the active transport of calcium and potassium ions across cell membranes, which is important for nerve impulse conduction, muscle contraction, and normal heart rhythm⁴.

3. Deficiency: Low levels of magnesium can lead to hypomagnesemia, which may result from inadequate intake, decreased renal absorption, or impaired gastrointestinal absorption. Risk factors for hypomagnesemia include gastrointestinal disease, chronic diarrhea, proton pump inhibitor therapy, alcohol use disorder, and diuretic use⁵.

4. Health Benefits: Adequate magnesium intake is associated with a lower risk of cardiovascular disease, osteoporosis, and metabolic disorders such as type 2 diabetes and hypertension⁶⁷.

5. Supplementation: Magnesium supplements are available in various forms, including magnesium oxide, magnesium citrate, and magnesium glycinate. These supplements can help improve magnesium status and may be used for specific health conditions such as constipation, eclampsia, or pre-eclampsia, and certain types of arrhythmia⁸⁹.

6. Recommended Intake: The Recommended Dietary Allowance (RDA) for adults is 400-420 mg per day for men and 310-320 mg per day for women. During pregnancy, the RDA is approximately 350-360 mg per day¹⁰.

Magnesium plays a critical role in maintaining health and proper bodily function. Ensuring adequate magnesium intake through diet or supplements can provide numerous health benefits and help prevent various health issues linked to magnesium deficiency.
