Are You Magnesium Deficient?
Magnesium is one of the most important minerals in the body, involved in hundreds of biochemical reactions, from energy production and muscle function to nerve signaling and sleep. Yet many people do not get enough, and low magnesium can quietly affect how you feel day to day.
Why magnesium matters
Magnesium plays a central role in cellular energy, muscle and nerve function, and bone health. A 2021 review in Nutrients (PMID 33573164) summarizes its importance across aging and health. Because it touches so many systems, inadequate magnesium can show up in nonspecific ways that are easy to overlook.
Possible signs of low magnesium
- Muscle cramps, twitches, or general tightness.
- Fatigue and low energy.
- Difficulty sleeping or restless, achy legs at night.
- Irritability and a lower tolerance for stress.
Food first
The best way to support healthy magnesium levels is through food. Good sources include leafy green vegetables, nuts and seeds, legumes, whole grains, and dark chocolate. A varied whole foods diet covers the needs of most people. There is also emerging interest in magnesium and sleep, explored in a 2025 review in Nature and Science of Sleep (PMID 41116797), though more research is still needed.
Before supplementing
Supplements can help in some cases, but more is not always better, and excess magnesium can cause side effects or interact with certain conditions and medications. If you suspect a deficiency or have ongoing symptoms, talk with a healthcare provider who can assess your situation and advise on testing or supplementation rather than guessing.
Magnesium is a small mineral with a big role. Building meals around magnesium rich whole foods is a simple, effective place to start.
