While magnesium has recently captured attention for its potential sleep-enhancing properties, this vital mineral has been quietly powering hundreds of crucial bodily functions all along. Although supplement sales are soaring, nutrition experts emphasize that the best way to harness magnesium’s benefits is through wholesome, natural food sources.
“Magnesium is truly a cornerstone of human health,” explains nutrition and wellness expert Samantha Cassetty, MS, RD, founder of Sam’s Plate and co-author of Sugar Shock. “This powerhouse mineral orchestrates over 300 biochemical reactions in your body. Beyond supporting heart health, blood pressure regulation, and blood sugar balance, it’s essential for maintaining strong bones and cellular energy production. What’s particularly fascinating is its dual role in stress management – magnesium helps regulate cortisol levels while supporting natural melatonin production, potentially improving both stress resilience and sleep quality.”
According to the National Institutes of Health’s guidelines, women should aim for 310-320 milligrams of magnesium daily, while men need 400-420 milligrams. The good news? Meeting these requirements through diet alone is surprisingly simple.
