Magnesium is an essential mineral crucial for various bodily functions, including muscle and nerve function, blood sugar control, and blood pressure regulation. Despite its significant health benefits, studies reveal that almost half of Americans do not meet the recommended daily intake of magnesium. Fortunately, increasing dietary consumption of magnesium-rich foods can effectively address this issue without resorting to supplements.
“Does the average American need to take a magnesium supplement?” asks nutrition expert Doerfler. “In short, no. We should focus on incorporating more fruits and vegetables into our diets.”
How much magnesium do you need?
The recommended daily intake of magnesium varies by age and gender. For women aged 19 to 30, the goal is to consume 310 milligrams per day (or 350 milligrams if pregnant). Women aged 31 and older should aim for 320 milligrams. In contrast, men should target 400 milligrams if they are between 19 and 30 years old and 420 milligrams if they are 31 or older.
In the U.S., severe magnesium deficiencies are uncommon and usually arise from underlying medical conditions, such as kidney disease or gastrointestinal disorders, which hinder the body’s ability to absorb and retain magnesium, explains Doerfler. If you’re generally healthy but not meeting magnesium intake recommendations, the body may adapt by reducing the amount excreted by the kidneys.
“The body has remarkable strategies to recycle and conserve magnesium,” says Doerfler. “However, inadequate dietary intake can still elevate the risk of conditions like cardiovascular disease, high blood pressure, and insulin resistance.”
Doerfler advises that those considering magnesium supplementation should first assess their dietary habits. Incorporating a few servings of specific plant foods daily can provide ample magnesium.
Here are some excellent dietary sources of magnesium according to the U.S. National Institutes of Health and the Department of Agriculture.
