Magnesium-Rich Foods: Top Dietary Sources of Magnesium
Magnesium is an essential mineral involved in muscle function, nerve signaling, energy production, and heart health. Because the body cannot produce magnesium, it must be obtained through food or supplements.
Many people do not get enough magnesium from their diet, which may contribute to fatigue, muscle cramps, poor sleep, and increased stress.
Here are the best magnesium-rich foods and how to increase your intake naturally.
Why Magnesium Is Important
Magnesium supports hundreds of biological processes, including:
- Energy production (ATP synthesis)
- Muscle contraction and relaxation
- Nervous system regulation
- Bone health
- Blood pressure control
- Blood sugar balance
Low intake may lead to symptoms such as fatigue, muscle cramps, and sleep disturbances.
For a full explanation, see our Magnesium guide.
How Much Magnesium Do You Need?
Recommended daily intake:
- Adult men: 400–420 mg per day
- Adult women: 310–320 mg per day
Many diets provide less than recommended amounts, making magnesium-rich foods especially important.
See our Magnesium dosage guide for details.
