The science, in plain English

What magnesium is actually doing

Three jobs, explained without the hype.

Mechanism 01

Small minerals. Electrical jobs.

How it works

Electrolytes are minerals that carry an electrical charge when they dissolve in body fluids. Sodium, potassium, chloride and magnesium are among them, and their balance matters to how cells work normally.

The everyday context

Where magnesium fits

The problem
19in 100

people in their twenties in the UK get less magnesium from food than the lower reference nutrient intake. Women’s intakes were lower than men’s. Source: NDNS secondary analysis, Frontiers in Nutrition, 2018.

Easy to fall short on, hard to read on a label

Magnesium sits in the green of leafy vegetables and the heart of seeds, nuts, beans and wholegrains. Refining strips much of it out: white flour keeps a fraction of the magnesium in wholemeal. So the more of your week that comes from processed food, the less magnesium tends to come with it.

Then there is the label. Many magnesium supplements lead with the weight of the whole compound and leave you to work out the magnesium. We print both: three forms of magnesium, and exactly how much magnesium they give you in two capsules, so you can compare like for like.

Magnesium questions, answered

How much elemental magnesium is in each serving?
One capsule provides 192mg of magnesium (51% of the nutrient reference value) and two capsules provide 384mg (102%). It comes from magnesium bisglycinate, citrate and malate.
What is the difference between magnesium glycinate, citrate and malate?
Each is magnesium bound to a different carrier molecule: glycinate to the amino acid glycine, citrate to citric acid and malate to malic acid. The carrier changes the compound’s weight, which is why labels show both the compound and the elemental magnesium.
How much magnesium do adults need a day?
The UK reference nutrient intake is 300mg a day for men and 270mg a day for women. Supplement labels compare against a single reference value of 375mg.
How many capsules should I take?
Take one to two capsules a day with water, at a time that suits your routine. One capsule provides 192mg of magnesium and two provide 384mg. Do not exceed two capsules a day.
Is it safe to take magnesium every day?
The NHS says taking 400mg or less of magnesium a day from supplements is unlikely to cause any harm. Two capsules provide 384mg. Speak to your GP or pharmacist first if you take medication or have a medical condition.
What does magnesium do in the body?
Magnesium contributes to the reduction of tiredness and fatigue, normal muscle function, normal functioning of the nervous system, normal energy-yielding metabolism, electrolyte balance, normal psychological function and the maintenance of normal bones and teeth.
Is Magnesium Glycinate 3-in-1 vegan?
Yes. The capsule shell is plant-based (hydroxypropyl methylcellulose) and the formula is suitable for vegans and vegetarians. It is not suitable for children.
Which foods are high in magnesium?
Sunflower and pumpkin seeds, almonds, soya beans, spinach, brown rice and wholemeal bread are good sources. A 30g handful of sunflower seeds provides about 117mg.
