10 Best Foods Rich in Magnesium

Magnesium is a mineral crucial for various bodily functions, including supporting nerve and muscle function, maintaining a healthy immune system, promoting bone health, and regulating blood pressure. Despite being present in vegetables, grains, beans, and seafood, many adults in the United States fail to meet the daily magnesium requirement.

This article explores high-magnesium foods and beverages, provides tips on incorporating more magnesium into your diet, and discusses when to consider supplements.

One excellent source of magnesium is fresh spinach leaves.

Best Food Sources of Magnesium

For optimal health, adults are advised to consume between 310 and 420 milligrams (mg) of magnesium daily. Thankfully, magnesium-rich foods are diverse, and here are some top sources with estimated serving amounts:

  • Seeds: Chia seeds (111 mg) or Pumpkin (156 mg)
  • Nuts: Cashews (74 mg) and Almonds (80 mg)
  • Greens: Spinach (78 mg)
  • Beans: Black beans (60 mg)
  • Soy products: Edamame (50 mg) and Soy milk (61 mg)
  • Protein: Peanut butter, smooth (49 mg)
  • Grains: Brown rice (42 mg)
  • Seafood: Salmon (26 mg)
  • Dairy products: Milk (24–27 mg) or Yogurt (42 mg)
  • Fruits: Bananas (32 mg) and Avocados (22 mg)

Importance of Monitoring Magnesium Intake

Many essential organs in the body rely on magnesium for proper functioning, but approximately 60% of U.S. adults are not getting enough of this vital nutrient.

While magnesium deficiency is uncommon, chronic cases can lead to symptoms like fatigue, muscle cramping, spasms, weakness, convulsions, and abnormal eye movements (nystagmus). Therefore, paying attention to magnesium intake is crucial for overall well-being.

What’s the Best Way to Get Magnesium: Through Food or Supplements?

The ideal method for obtaining magnesium depends on various factors such as age, diet, and overall health. Generally, most healthy adults can meet their magnesium needs through a balanced diet, while some individuals may benefit from magnesium supplements to address deficiencies.

If you’re considering supplementation, it’s important to note that different forms of magnesium supplements are available, including:

  • Magnesium oxide: Used to address magnesium deficiency or constipation issues.
  • Magnesium citrate: Acts as a laxative and can help with occasional constipation.
  • Magnesium chloride: A supplement to boost magnesium levels, potentially beneficial for conditions like prediabetes.

Before incorporating any new supplements into your routine, consult with a healthcare provider.

It’s crucial to be aware that supplements and vitamins in the United States are not regulated as rigorously as medications. They don’t undergo the same FDA approval process for safety and effectiveness.

Enhancing Magnesium Absorption

Approximately less than half of the magnesium consumed in your diet is absorbed by the body. Certain medical conditions and medications can further reduce magnesium absorption, making it challenging for the body to maintain sufficient mineral levels.

This is particularly relevant for children, older adults, individuals with diabetes, those with alcohol dependence, people with hypertension, and individuals taking diuretics or proton pump inhibitors.

To improve magnesium absorption, experts may suggest:

  • Avoiding simultaneous intake of zinc supplements, as it may interfere with magnesium absorption.
  • Opting for a powdered form of magnesium supplement, as liquid-dissolvable versions tend to absorb better in the body.
  • Ensuring an adequate but not excessive intake of vitamin D and calcium, as these nutrients collaborate with magnesium absorption.

Magnesium in Beverages

Apart from obtaining magnesium from food, certain beverages can also contribute to your magnesium intake, including:

  • Soy milk
  • Tap, mineral, or bottled water (varies by brand and source)
  • Orange juice

Magnesium-Rich Meal Ideas

To include more magnesium in your diet, consider these meal ideas recommended by experts:

  • Breakfast: Low-fat Greek yogurt with a banana or fortified breakfast cereal.
  • Snack: An ounce of almonds or pumpkin seeds.
  • Lunch: Half an avocado on whole grain toast or a salad.
  • Dinner: Salmon with brown rice and a raw kale salad.
  • Dessert: A square of dark chocolate.

Potential Risks of Excessive Magnesium Intake

Consuming too much magnesium can pose risks to your health. In less severe cases, such as overdoing magnesium supplements, you might encounter side effects like stomach cramps or diarrhea.

However, in extreme situations where magnesium is taken in excessively high doses, there’s a potential for magnesium toxicity. This condition arises when the levels of this mineral in your bloodstream become dangerously elevated. While magnesium toxicity is rare, it can result in low blood pressure, irregular heartbeat, and, in extreme cases, be life-threatening.

In summary, magnesium is a vital mineral necessary for your body’s proper functioning, present in various foods such as vegetables, beans, grains, nuts, and dairy. Despite its importance, many adults in the United States fall short of the recommended daily intake. To enhance magnesium levels, experts advise making simple dietary adjustments. Before considering magnesium supplements, it’s crucial to consult with a healthcare provider to ensure the suitability and proper dosage for your individual needs.
