Magnesium Supplements: Benefits and Forms

What Are Magnesium Supplements?

Magnesium supplements are dietary products designed to help individuals meet their daily magnesium requirements. Magnesium is an essential mineral that plays a critical role in over 300 enzymatic processes in the human body, including energy production, muscle function, nerve signaling, and DNA synthesis. While magnesium is naturally present in foods like leafy greens, nuts, seeds, and whole grains, many people do not get enough from their diets, making supplementation necessary.

Bioavailability: Why It Matters

Bioavailability refers to how well a nutrient is absorbed and utilized by the body. Organic forms of magnesium, such as magnesium citrate, glycinate, and L-threonate, generally have higher bioavailability compared to inorganic forms like magnesium oxide. Choosing a form with higher bioavailability ensures you get the most out of your supplement.
