Magnesium and Zinc benefits are numerous, and they are both crucial nutrients your body needs to function at its best. They are found in certain foods, and in supplements as single dietary ingredients but are also increasingly found together in a Zinc and Magnesium supplement for enhanced convenience.

Did you know that many of us don’t get in enough Magnesium and Zinc every day? According to research, approximately 15-20% of the U.S. population is Magnesium deficient and around just over 15% of Americans do not consume enough of this essential trace mineral from diet alone and are at risk for Zinc deficiency.[1][6]

In this article, we’ll discuss the nine benefits of Magnesium and Zinc and key food and supplement sources of these essential nutrients.

What is Magnesium Good For?

You may be wondering what does Magnesium do for the body?

Magnesium is an abundant mineral found throughout our body and is primarily stored in our bones. It is considered an electrolyte and it plays an important role in maintaining mineral balance, which supports many vital functions in the body.

As noted above, despite the known importance of Magnesium, many Americans don’t meet the Food and Nutrition Board’s Recommended Daily Allowance (RDA) guidelines for this nutrient.

Magnesium benefits include:[1]

  • Supports muscle relaxation
  • Supports nerve, muscle, heart, and bone health
  • Supports essential nerve, muscle, and heart function
  • Essential mineral required in over 300 enzymatic reactions in the body

Getting in enough via food or Magnesium supplements supports health. A Magnesium-rich diet may also contain other key nutrients that collaboratively work together to support health such as soybeans which are an great source of Magnesium and Zinc. This is also the case in terms of a Magnesium supplement combined with other nutrients such as ZincZinc and/or Calcium.[3]

What is Zinc Good For?

Like Magnesium, Zinc is an essential mineral involved in many important bodily processes.At least 15% of Americans have a Zinc nutrient gap so it is critical to understand how to get in enough of it.[6,7]

One of the most common reasons many people take Zinc is to support their immune system.

In addition to supporting the body’s natural immune defenses, Zinc provides the following key benefits: [4]

  • It is vital for normal growth and development.
  • Helps support a healthy immune system.
  • Antioxidant Support
  • Supports the body’s natural immune defense system.

As you can see, Zinc benefits are numerous. The body doesn’t naturally produce Zinc, so we have to obtain it through food and/or supplements. To reap the benefits of Zinc, both food and supplements may be needed, depending on your typical diet.
