what is magnesium?
magnesium is an essential mineral involved in several hundred processes in the body, from energy production to muscle and nerve function. it's found across a wide range of foods, with pumpkin seeds, leafy greens and wholegrains among the more concentrated dietary sources.
its role in the body
magnesium has a number of recognised roles, including contributing to the reduction of tiredness and fatigue, normal muscle function, normal psychological function, and the maintenance of normal bones and teeth. it also plays a part in normal energy yielding metabolism and normal protein synthesis. because of its role in muscle and nervous system function, magnesium is often discussed in relation to sleep quality, stress and general relaxation, though it's worth noting that while there's a plausible biological basis for these connections, magnesium should be seen as one supportive piece of a broader picture of wellbeing rather than a guaranteed fix for sleep or stress difficulties.
good dietary sources
- pumpkin seeds and other seeds
- leafy green vegetables such as spinach and kale
- wholegrains, including brown rice and oats
- dark chocolate and legumes
things to consider
magnesium deficiency from diet alone is relatively uncommon in people eating a varied diet, but certain groups may be more at risk, including people with digestive conditions that affect nutrient absorption, people who drink alcohol heavily, and older adults. very high intakes of magnesium from supplements, rather than food, can cause digestive upset such as diarrhoea, so it's worth sticking to recommended amounts unless advised otherwise by a healthcare professional. people with kidney conditions should be particularly cautious with magnesium supplementation and should seek medical advice first, since the kidneys are responsible for clearing excess magnesium from the body.
the takeaway
magnesium supports energy, muscle function and normal psychological wellbeing, and it's a mineral that pumpkin seeds and other whole foods can help provide as part of a naturally varied, balanced diet.
