Magnesium and your bones: the often-forgotten mineral

When it comes to strong bones, most people immediately think of calcium and vitamin D. But there is a third mineral that is often overlooked: magnesium. About 60% of the magnesium in your body is stored in your bones, and magnesium contributes to the maintenance of normal bones. In this article you can read how magnesium relates to calcium and vitamin D, how much you need and which form of magnesium suits you.

Magnesium and your bones

Magnesium is a mineral that is largely stored in your bones. According to the health claims authorised by the EU, magnesium contributes to the maintenance of normal bones and normal teeth. Magnesium also contributes, among other things, to the reduction of tiredness and fatigue, to normal muscle function and to normal energy-yielding metabolism.

Research is also looking at the interplay between magnesium, vitamin D and the hormones that regulate calcium balance, such as parathyroid hormone.

Whether your needs are higher depends on factors such as age, lifestyle and diet. Athletes, older people and people who take certain medicines (such as acid reducers or diuretics) often pay extra attention to their magnesium intake. If you take medication or are unsure, talk to your GP or pharmacist.

Magnesium, calcium, vitamin D and K: what do they do?

For your bones it is not about one single nutrient, but about a varied diet in which several nutrients come together:

  • Calcium is needed for the maintenance of normal bones.
  • Vitamin D contributes to the normal absorption of calcium and to the maintenance of normal bones.
  • Magnesium contributes to the maintenance of normal bones.
  • Vitamin K contributes to the maintenance of normal bones.

If you want to use a supplement, you can choose separate products or a combination formula that brings these nutrients together in one product.

Frequently asked questions about magnesium for your bones

Which form of magnesium do you choose?

Choosing the right form

Magnesium comes in many different forms in supplements. They differ in the compound the magnesium is bound to, in the magnesium content per gram and in practical properties. The most common forms:

Magnesium bisglycinate (glycinate)

Magnesium bound to the amino acid glycine. Gentle on the stomach and often chosen for use in the evening.

Magnesium citrate

Magnesium bound to citric acid. Dissolves well in water. At higher doses it can have a mild laxative effect.

Magnesium malate

Magnesium bound to malic acid (malate), a substance found naturally in fruit.

Liquid ionic magnesium

Magnesium in dissolved form. Practical for anyone who does not want to swallow capsules or wants a flexible dose.

Magnesium oxide

Widely used because of its high magnesium content per gram. At higher doses it can have a laxative effect.

Which form you choose mainly depends on your preference (capsule, powder or liquid) and on how your stomach reacts. Magnesium contributes to the maintenance of normal bones whatever the form, as long as the product provides enough magnesium per daily dose.
