Did you know that having high levels of magnesium can reduce our risk of sudden cardiac arrest by 40%? There’s more. Getting the appropriate levels of magnesium can reduce or eliminate PMS symptoms. It can also help with migraines, depression, muscle pain, diabetes type 2 prevention, and many other important functions in our body. 

Generally speaking, magnesium is great for our bones. We actually store 50% of the total magnesium in our body, in our bones. It’s also great for our muscles, nerves, DNA, neurons and, of course, our heart and circulation.

Unfortunately, the average person in the U.S. is not getting enough magnesium in their diets. This is because the best sources of magnesium are whole-plant foods. In fact, someone following a diet high in animal-based protein and low in plants is at a higher risk of deficiency. And taking magnesium supplements is probably not the best idea since supplements with over 350 mg of magnesium may lead to toxicity. Instead, we can eat as many whole-plant foods rich in magnesium as we want, and our body will simply excrete any excess. 

The great news is that getting our recommended magnesium intake and then some is easy when we eat plenty of whole-food plants, because magnesium is present in different food groups, especially in legumes, dark leafy greens, grains, and different nuts and seeds.

Magnesium Personalized Calculator

See how much magnesium you and your family members need, according to the Dietary Guidelines for Americans, 2020-2025.

* The Upper Intake Levels (ULs) are lower than the Daily Value (DV) and the Recommended Daily Allowance (RDA) for many groups because the ULs only apply to magnesium supplements and medications, which can lead to toxicity. DV and RDAs take into consideration dietary sources of magnesium which do not result in toxicity no matter how much we ingest.

Terminology:

  • Daily Value (DV): The recommended amount of nutrients to consume each day for individuals who are 4 years old or older.
  • Recommended Daily Allowance (RDA): The recommended amount of nutrients to consume each day according to the individual’s age, gender, and whether a woman is pregnant or breastfeeding.
  • Upper Intake Level (UL): The highest amount of nutrient intake that will not pose adverse health effects on most individuals.

High levels of magnesium may reduce the risk of sudden cardiac arrest by 40%.

The Daily Value (DV) and Recommended Daily Allowances (RDAs) tell us the minimum amount of magnesium we should consume to avoid being deficient, but experts recommend ingesting between 400 and 700 mg a day through dietary sources. It’s easy to support our heart and overall health with these amounts when following a balanced, whole-foods, plant-based diet. Unfortunately, most Americans are not even getting the DV of 420 mg. The average intake is 300 mg.

Women who suffer from PMS often have low levels of magnesium.

Ironically, high doses of magnesium supplements may also cause abdominal cramping, plus nausea, and diarrhea. Instead of getting our magnesium through supplements, we should aim at getting at least 400 mg through our diet. Starting your day with a bowl of overnight oats, eating a handful of almonds or pumpkin seeds as a snack, and eating beans and dark greens for lunch or dinner will give you all the magnesium you need in one day.

The darker your greens the higher they are in magnesium content.

Magnesium is the central atom in chlorophyl, therefor a good way to select greens that are high in magnesium is simply selecting those that are darker green.

Zinc supplements may interfere with magnesium absorption.

High doses of zinc supplementation interfere with our bodies’ ability to absorb and regulate magnesium. If you need to take zinc supplementation, get your magnesium levels checked. Otherwise, opt for getting your zinc from your whole-foods, plant-based diet.

Acid reflux, peptic ulcer medications and diuretics affect magnesium levels.

Prescription medication for acid reflux or peptic ulcers may lower levels of magnesium in the blood. Also, diuretics can increase or decrease the levels of magnesium in the urine.

Comparison of Magnesium Sources

You may be wondering about other potential sources of magnesium, such as supplements and animal-based products. Below, we make a quick and simple comparison between the three choices.

Best source!
Plant-Based
No risk of toxicity
Our kidneys get rid of any excess through urine. Also, when we don’t get enough for a short time, our kidneys help us retain magnesium by limiting the amount we lose in urine.
Supplements
Toxicity in high doses
Getting excessive amounts of magnesium from supplements can lead to diarrhea, nausea, abdominal cramping, and in extreme cases, irregular heartbeat and cardiac arrest.
Animal-based
Plant-based sources are far richer in magnesium than animal-based sources. 1 cup of yogurt provides 10% DV and 3 oz of salmon provide 6% DV. Compare that to 1/4 c pumpkin seeds providing 45% DV or 1 cup of cooked spinach providing 37% DV.
A diet high in saturated fat and low in magnesium puts people at a higher risk of cardiovascular disease.
