Magnesium , the essential mineral that has been overlooked for long, is finally having its moment. From providing better sleep to boosting cardiovascular health, magnesium plays multiple roles. When the diet falls short, people turn to magnesium supplements . But guess what? Most of us are taking magnesium supplements the wrong way, says Dr. Amy Shah, a double-board-certified doctor and wellness expert trained at Cornell, Harvard, and Columbia, who specializes in food allergies, hormones, and gut health. She has explained the different types of magnesium supplement and their benefits.

Magnesium is back in vogue

“There’s a lot of interest in magnesium these days,” says Dr. Shah.

“Why the interest? Well, there have been recent studies that looked at brain health in women being better with a 41% increase in magnesium levels over baseline,” she explains, in a post shared on Instagram.

The recommended daily amount of magnesium is 320 milligrams (mg) a day for women and 420 mg a day for men.

Some of the key roles of magnesium in the body include:

  • Energy production
  • Muscle function
  • Maintains healthy brain function
  • Strengthens bones
  • Balances blood sugar
  • Supports heart health
  • Reduces inflammation
  • Helps in protein synthesis
  • Aids DNA and RNA production
  • Supports electrolyte balance
