Magnesium – important for teeth grinding – An essential mineral for stress and vitamin D supplementation
Magnesium is a vital mineral that many people are deficient in without realizing it. Magnesium plays a central role in numerous physiological processes in the body. It is involved in muscle relaxation , enzyme function, energy production, nerve conduction, and, last but not least, the activation of vitamin D. The need for magnesium can increase significantly, especially during periods of high stress, with frequent teeth grinding , and when taking high doses of vitamin D.
Teeth grinding – medically known as bruxism – is more than just a nighttime habit. It's an expression of inner tension and is often accompanied by chronic activation of the sympathetic nervous system. This process consumes large amounts of magnesium , as magnesium has a regulating effect on the nervous system and a relaxing effect on the muscles . A deficiency can exacerbate symptoms, worsen tension, and impair sleep quality. Therefore, anyone who regularly grinds their teeth should keep an eye on their magnesium levels .

The effects of vitamin D are also closely linked to magnesium . Several enzymatic steps are necessary for vitamin D to be activated in the body – and these require magnesium as a cofactor . Therefore, anyone taking high doses of vitamin D without ensuring adequate magnesium intake risks the vitamin not being able to fully exert its effects. Furthermore, vitamin D activation increases the body's magnesium consumption .
Another crucial point is the form in which magnesium is ingested. Not every compound is absorbed equally well by the body . Many preparations contain magnesium oxide – an inorganic compound with a very strong chemical bond. For magnesium oxide to become available in the body, it must dissociate into free magnesium ions in the stomach. However, this only occurs with sufficient stomach acid . Many people, especially the elderly or those taking proton pump inhibitors , have reduced stomach acid levels. This means that the magnesium oxide is not properly broken down. It remains in the intestines, binds water , and can thus lead to diarrhea . This is not because the magnesium itself has a laxative effect, but because it cannot be absorbed in this form and therefore remains osmotically active .
Another criticism of magnesium oxide is its low bioavailability . Studies show that the body can only actually utilize about four to ten percent of the magnesium ingested from this compound. Nevertheless, some medical experts suggest that magnesium oxide can be quite effective in young, healthy individuals with sufficient stomach acid . This isn't wrong – but it doesn't apply to the general population.
Organic magnesium compounds such as magnesium citrate are absorbed much better. or magnesium glycinate Magnesium citrate is bound to citric acid, dissolves well in water , and is readily absorbed even in cases of weak stomach acid. Magnesium glycinate is a chelate – a compound of magnesium and the amino acid glycine . This form is absorbed particularly efficiently via amino acid transporters , is very gentle on the stomach, and is well tolerated even by sensitive individuals.
The German Nutrition Society recommends a daily magnesium intake of approximately 300 to 400 milligrams for adults. In cases of increased need – for example, due to intense exercise, stress, pregnancy, or even teeth grinding and vitamin D therapy – this amount can be significantly higher. Since magnesium is generally well-regulated and excess amounts are excreted via the kidneys , a moderate overdose is rarely problematic.
You don't need to be a chemist to understand magnesium. A basic understanding of its importance is sufficient. You don't need to know every number and compound, but paying attention to the form of magnesium you're consuming is a sensible step towards better well-being. Those who grind their teeth at night or take vitamin D supplements should especially consider magnesium as a supportive partner .
