Magnesium: The Calming Mineral Most People Overlook

Magnesium is a mineral your body uses in more than 300 enzyme systems, helping with muscle and nerve function, energy production, steady heart rhythm, bone health and blood sugar regulation. It is sometimes called the "relaxation mineral" because it helps muscles release after contracting and is involved in the calming side of the nervous system. Yet US surveys suggest that about half of Americans eat less magnesium than they need from food, partly because refined grains and processed foods lose much of it. The gentle answer begins in the kitchen: seeds, nuts, beans, leafy greens and whole grains are rich, delicious sources.

Calm is not only a state of mind. It is also built, meal by meal, from the minerals of the earth.

How much do we need?

According to the US National Institutes of Health, adults need:

Men: 400 mg a day (ages 19 to 30) and 420 mg (31 and older)
Women: 310 mg a day (ages 19 to 30) and 320 mg (31 and older)
Pregnancy: 350 to 360 mg a day
Upper limit from supplements for adults: 350 mg a day. This limit does not apply to magnesium in food, which the body handles well.

Top food sources

Approximate amounts from NIH and USDA data:

Pumpkin seeds, 1 oz: about 156 mg
Chia seeds, 1 oz: about 111 mg
Almonds, 1 oz: about 80 mg
Spinach, boiled, ½ cup: about 78 mg
Cashews, 1 oz: about 74 mg
Black beans, ½ cup: about 60 mg
Edamame, ½ cup: about 50 mg
Peanut butter, 2 tablespoons: about 49 mg
Brown rice, ½ cup: about 42 mg
Dark chocolate (70 to 85 percent), 1 oz: about 65 mg

A day with a handful of seeds, a bowl of beans and greens, and whole grains can easily reach the recommended amount.

Mineral water

Natural mineral waters vary widely. Some contain over 100 mg of magnesium per liter, and the label lists the amount. Research suggests magnesium in water is well absorbed. See Water as First Prayer.

What can lower magnesium

Diets high in refined and processed foods
Heavy alcohol use
Some medicines, such as certain diuretics and long-term acid-reducing medicines
Digestive conditions that affect absorption
Type 2 diabetes

Calming magnesium rituals

An evening seed bowl: pumpkin seeds and a few squares of dark chocolate with herbal tea.
A green dinner: spinach, beans and brown rice.
An Epsom salt bath: Epsom salt is magnesium sulfate. Whether much magnesium passes through the skin is not proven, but a warm bath is wonderfully relaxing. See Evening Saltwater Reset.

About supplements

Supplements come in many forms and can cause digestive upset, and too much can be dangerous for people with kidney problems. They can also interact with some antibiotics and other medicines. Please talk with a trusted practitioner before taking magnesium supplements.
