Magnesium
Magnesium
Magnesium is a mineral involved in hundreds of processes throughout the body — it’s quietly one of the busiest nutrients you have. It’s especially loved for its calming role, which is why it comes up so often in conversations about stress and sleep.
What does magnesium do?
Supports energy production in every cell
Helps muscles and nerves work — including relaxing muscles after they contract
Helps the body manage stress and wind down for sleep
Supports healthy blood pressure, blood sugar and bones
Acts as an antioxidant, helping make glutathione (one of the body’s most powerful protective compounds)
It also partners well with vitamin B6, which helps your body absorb and use it.
Which foods are rich in magnesium?
Some of the best sources are nuts and seeds (pumpkin seeds are excellent), legumes, whole grains, dark leafy greens, avocado and — happily — good-quality dark chocolate. Mineral water can be a surprisingly useful source too, as some are naturally magnesium-rich.
Can you have too little — or too much?
Falling a little short is more common than people realise, particularly with diets built around processed foods, during stressful stretches, or while following a weight-loss diet — it can show up as muscle cramps, tiredness or restless sleep. You won’t get too much from food; very high supplement doses mainly cause loose stools.
