If there’s one mineral that keeps coming up in conversations, it’s magnesium. Not because it’s a miracle cure, but because so many people get just a little too little of it without realising.
Magnesium is involved in hundreds of enzymatic processes in your body. It contributes to normal muscle and nervous-system function, to a normal energy-yielding metabolism, and to the reduction of tiredness and fatigue. In short: it’s in everything, and that’s precisely why you feel it when there’s too little.
Why a shortfall is so common
Several things work against you at once.
- The soil is depleted. Vegetables and grains contain less magnesium on average than they did decades ago, because the ground they grow in has grown poorer.
- Processed food loses it. When grains are refined, most of the magnesium disappears. The whiter and finer, the less is left.
- Stress uses it up. This is the awkward one: when you’re stressed, your body excretes more magnesium. And with less magnesium, you respond more sensitively to stress. So the circle keeps itself going.
- Coffee and alcohol flush it out. Both raise excretion through your kidneys.
Women in and around menopause often notice this all the more, when sleep and tension are already shifting.
Your plate first, then a jar
Before you think about supplements: plenty of magnesium is simply in real food.
- Dark leafy greens such as spinach and kale.
- Nuts and seeds, especially pumpkin seeds, almonds and cashews.
- Pulses such as black beans and chickpeas.
- Wholegrains such as porridge oats and brown rice.
- Dark chocolate (70% or higher) and avocado, for anyone after a tasty reason.
Eat from this daily and you lay a solid base. A supplement is a top-up, not a replacement for a good plate.
If you do want to top up: which form?
This is where people often get it wrong. Not all magnesium is equal; the form decides how well you absorb it and what you use it for.
- Magnesium bisglycinate (or glycinate). Gentle on your stomach and well absorbed. Lovely for the evening, because it feels calming.
- Magnesium citrate. Well absorbed and affordable. At higher doses it can be mildly laxative, which for some people is rather welcome.
- Magnesium malate. Often chosen by people looking for a little extra support for their energy metabolism during the day.
- Magnesium oxide. Cheap and widely sold, but poorly absorbed. Here you’re mainly paying for a nice number on the label.
My practical line: choose bisglycinate or citrate, start low, and see how your body responds. Build up slowly. If you’re unsure because of medication or your kidneys, do have a quick word with your doctor or pharmacist.
How you notice it
Magnesium isn’t a pill that makes you feel something within ten minutes. It works in the background. But people who get their intake in order, through their plate and a good supplement where needed, often notice they settle a little more easily and their energy runs more evenly through the day.
Small mineral, wide reach. Exactly the kind of support your body can actually put to use.
