Top 12 Plant-Based Magnesium Sources

What is magnesium?

Magnesium is a mineral that can easily be obtained from plant foods. While all essential vitamins and minerals are important, magnesium receives special attention as a star player in the nutrition world because it is involved in over 600 enzymatic reactions in the body, including energy metabolism, blood sugar and blood pressure regulation, nerve signaling, and bone and protein synthesis.1, 2

Getting enough magnesium can also help with stress as it acts as a natural, mild muscle relaxant and sleep aid. Some studies have even linked diets that are rich in magnesium intake with decreased symptoms and risk of depression, heart disease and migraines. 3, 4, 5

How much magnesium do I need?

The amount of magnesium you need will vary, as your body requires increasing amounts as it ages. Adults males should target over 400 mg of magnesium daily, and females over 310 mg daily.

Am I getting enough magnesium?

If you’re eating the standard American diet, you’re likely missing out on several essential nutrients, including magnesium. 10 Studies suggest that up to two thirds of Americans aren’t getting enough of this essential mineral. If you fall into the following groups of people, then you may face an additional risk for magnesium deficiency: (2)

  • People with gastrointestinal issues, including Crohn's, celiac and enteritis.
  • People with type 2 diabetes.
  • People with alcohol dependence. 
  • Older adults.
  • People taking these medications:
    • Bisphosphonates
    • Antibiotics
    • Diuretics
    • Proton pump inhibitors

If you are at risk for or show any of the symptoms of magnesium deficiency, like loss of appetite, nausea, vomiting, fatigue, depression and weakness, talk to your healthcare provider to get the help you need.
