Magnesium & Your Health: Most of us do not get enough magnesium in our diets.


Magnesium is one of the most common nutrient deficiencies worldwide. Studies suggest that up to 50% of people in the U.S. and other developed countries do not get enough magnesium from their diets.

Why Is Magnesium Deficiency So Common?

Several factors contribute to widespread magnesium deficiency:
✔ Poor Diet – Processed foods lack magnesium, and many people don’t eat enough leafy greens, nuts, and whole grains.
✔ Soil Depletion – Modern farming practices have reduced magnesium levels in soil, leading to lower amounts in fruits and vegetables.
✔ High-Stress Lifestyles – Stress depletes magnesium levels, increasing the body's need for this mineral.
✔ Caffeine & Alcohol Consumption – Both substances can lead to magnesium loss through urine.
✔ Certain Medical Conditions – Diabetes, digestive disorders (like Crohn’s and celiac disease), and kidney disease can impair magnesium absorption.

Symptoms of Magnesium Deficiency

Common signs of low magnesium include:

  • Fatigue and muscle weakness

  • Muscle cramps and spasms

  • Anxiety and irritability

  • Poor sleep and insomnia

  • Irregular heartbeat

  • High blood pressure

Since magnesium plays a role in over 300 biochemical processes, deficiency can affect many aspects of health. If you’re concerned about your magnesium levels, eating magnesium-rich foods or considering a supplement might help.

In her interview on the Rich Roll Podcast, Dr. Uma Naidoo, a nutritional psychiatrist, emphasizes the significant role of magnesium in mental health. She highlights that magnesium is crucial for mood regulation and anxiety reduction, noting that many individuals are deficient in this essential mineral. Dr. Naidoo recommends incorporating magnesium-rich foods into one's diet, such as avocados, leafy greens, dark chocolate, beans, and nuts, to help alleviate symptoms of anxiety and depression. She also discusses the potential benefits of magnesium supplementation but advises consulting with a healthcare professional to determine appropriate dosage and to monitor electrolyte levels. Overall, Dr. Naidoo underscores the importance of adequate magnesium intake for supporting mental well-being.
