The Benefits of Magnesium: Everything You Need to Know

Written by: Millerlandy Popayan, Research and Development Scientist

“One Mineral, Many Responsibilities.” This is one way to describe magnesium. While most people understand the value of certain vitamins and other supplements, magnesium is frequently overlooked by consumers. Magnesium is a vital nutrient in our diet, and here is why.

What is Magnesium?

Magnesium is an essential mineral for the human body. Your body cannot make its own magnesium, so it must be incorporated into your diet. Magnesium is naturally present in many foods added to other food products, and available as a dietary supplement.

How Much Magnesium is Recommended Per Day?

The recommended dietary allowance for adults aged 19 and older is 400 to 420 milligrams (mg) daily for men, 310 to 320 mg for women, and about 350 to 360 mg daily for women during pregnancy and lactation.¹ To add some extra magnesium in your diet, try out our Cal-Mag complex!

What Does Magnesium Do In Your Body?

Magnesium is involved in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation.¹ Magnesium is also critical for energy production, bone development, DNA and RNA synthesis, antioxidant support, and more.¹ Let’s take a closer look at some of these functions.

Supports Bone health

Magnesium plays a critical role in both bone formation and the maintenance of bone density as we age, aiding in normal bone structure.¹

Improves Metabolism

Magnesium participates in protein, lipids and carbohydrate metabolism and improves glucose and insulin metabolism.²

Supports Sleep

Magnesium may play a role in supporting sleep by regulating certain neurotransmitters that calm the nervous system and allow the brain to transition to a restful state.³ 4Life Transfer Factor® SleepRite® is a great way to get in your magnesium for a restful night’s sleep!

Reduces Cortisol

Magnesium may help to reduce the levels of the stress hormone cortisol in the body.⁴

Maintains a Healthy Heart

Magnesium regulates nerve and muscle function throughout the body, including the heart muscle. It helps the heart maintain a healthy rhythm⁵, is involved in the regulation of blood pressure.⁶ Try 4Life Transfer Factor® Cardio, which contains magnesium and other essential vitamins for heart health support!

Supports Brain Homeostasis

Magnesium is involved in the maintenance of the homeostasis of all the tissues, including the brain.⁷ The American Academy of Neurology and the American Headache Society concluded that magnesium therapy may also be effective for migraine support.⁸

Magnesium’s Role in the Immune System

Magnesium is particularly important for the activation of T-cells. T-cells are a type of white blood cell in the immune system. T-Cells only effectively eliminate abnormal or infected cells in a magnesium-rich environment.⁹

Magnesium and the microbiome

Evidence suggests that magnesium levels positively impact the microbiome by maintaining the integrity of the intestinal barrier function and the concentration of beneficial bacteria.⁹

Why Don’t We Get Enough Magnesium?

Even though there are plenty of magnesium-rich foods, 48% of Americans of all ages ingest less magnesium from food and beverages than their respective EARs (Estimated Average Requirement).1 One reason is that the highly processed foods that many people consume lack sufficient magnesium. Also, approximately only 30% to 40% of the dietary magnesium consumed is absorbed by the body.5 In addition to dietary factors, a variety of medications and health conditions can lead to magnesium loss.5 The body’s intake or absorption of magnesium can be affected by aging, chronic diarrhea, diabetes, and even high alcohol usage.5

How To Get More Magnesium

Food is a great source of magnesium, which is readily available in whole, unprocessed foods such as:

  • Leafy greens, spinach, kale, and collard greens
  • Seeds and nuts, particularly pumpkin seeds, chia seeds, almonds, and cashews
  • Beans and legumes, including black beans, kidney beans, edamame and peanuts
  • Whole grains, including brown rice, oatmeal and whole grain bread
  • Dairy, such as yogurt and certain milks, including cow's milk and almond milk
  • Fish, particularly salmon and halibut

    Take Magnesium Supplements

    Types of Magnesium Supplements


    Magnesium supplements are available in a variety of forms: magnesium oxide, magnesium chloride, magnesium carbonate, magnesium lactate, magnesium malate, magnesium taurate, magnesium l-threonate, magnesium sulfate, magnesium orotate, magnesium ascorbate, and magnesium amino acid chelate. Two of the most common forms that are well-tolerated and properly absorbed in the body are magnesium glycinate and magnesium citrate. An increasing number of magnesium supplements contain combination formulations with multiple minerals or vitamins in a single product. They are designed to give the body the nutrients needed to support optimal health. Magnesium is a mineral that plays many roles and supplementing it can have a significant impact on your health.
