Does Coffee Have Magnesium?

Coffee is often thought of as a pick-me-up, but you may be surprised to learn that it actually contains a variety of nutrients. One of these nutrients is magnesium. Let’s explore the facts and see how much magnesium is really found in coffee.

What Is Magnesium?

Magnesium is an essential mineral needed for healthy functioning of the body, as it is involved in many biochemical reactions. It is especially important for nerve and muscle activity, DNA production, and metabolism of carbohydrates and proteins.

How Much Magnesium Is in Coffee?

The amount of magnesium found in coffee varies depending on the type and brewing method. Generally, an 8 ounce cup of coffee contains around 3–11 mg of magnesium. Instant coffee contains less magnesium than brewed coffee, however, even the highest estimates still only come to 1/3 of our recommended daily magnesium intake (between 310–420 mg/day).

How Does Magnesium Benefit Us?

The benefits of magnesium include:

  • Reduce stress and anxiety: Magnesium helps regulate cortisol, a hormone linked to stress.
  • Lower risk of developing Type 2 Diabetes: Studies have shown that an adequate intake of magnesium is linked to a lower risk of developing Type 2 Diabetes.
  • Reduce inflammation: Magnesium helps reduce inflammation, which can help to reduce symptoms associated with some chronic conditions such as arthritis.
  • Improve sleep quality: This mineral has been linked to improved sleep, which is essential for keeping the body healthy and rested.


In conclusion, coffee contains small amounts of magnesium but it is unlikely to be enough to make a significant difference in your magnesium intake. It is better to get magnesium from other sources such as leafy greens, nuts, and legumes. However, if you are looking for a small boost in your magnesium intake or some of the other benefits associated with the mineral, a cup of coffee may be an option.
