5 things to consider when taking magnesium supplements
If the label says "500 mg magnesium," that's what the body absorbs. Many supplements mention the weight of the compound, not the elemental magnesium (i.e., the weight of the component) that the body uses. For example, 1000 mg of magnesium citrate contains only about 160 mg of elemental magnesium. Always pay attention to the "elemental magnesium" figure. This is the actual amount the body can utilize. Skipping this step is like buying a mango by weight, not by the peel.
If it's a supplement, it should be clean and safe. Many magnesium supplements contain added flavorings, artificial colors, preservatives, and even allergens like soy or gluten. While these aren't always harmful, they can cause sensitivities in some people or reduce the purity of the product. Reading the ingredient list is just as important as checking the front label. If a supplement tastes more like a dessert than a mineral, it may not be the right choice.
If it's sold in a pharmacy or online, it should be safe. Dietary supplements aren't as tightly regulated as medications, meaning quality can vary. Reputable brands often have their products tested by third-party laboratories. Looking for a certification seal or lab-tested note adds an extra layer of security. It helps ensure the magnesium in the product is the same as what's stated on the label and not something else.
A higher dose means better results. Excessive magnesium intake can cause side effects such as diarrhea, nausea, and even low blood pressure. The recommended daily allowance (RDA) for most adults is approximately 310–420 mg of elemental magnesium, depending on age and gender (source: National Institutes of Health).
Supplements should fill nutritional gaps rather than overwhelm the system. If your diet already includes magnesium-rich foods (such as spinach, almonds, or pumpkin seeds), a lower supplement dose may be sufficient.
