How does magnesium citrate differ from other forms of magnesium, and why does it matter? — Magnesium citrate 400 mg + B6 OstroVit, 90 tablets

Magnesium comes in different chemical forms: oxide, sulphate, glycinate, citrate and others. The difference between them is not a matter of marketing but a practical one: it concerns solubility and what proportion of the substance is actually absorbed in the gut.

Magnesium citrate is an organic salt formed from magnesium and citric acid. Thanks to its good solubility in water, it is absorbed more efficiently than, for example, magnesium oxide, which for a long time was the most common and cheapest form in supplements. Oxide contains more magnesium by weight, but a significant part of it passes straight through without being absorbed.

For everyday use, this means that at a comparable dose the citrate form is more likely to actually deliver magnesium into the body rather than simply pass through the digestive tract.

In this product, magnesium citrate is combined with vitamin B6, which is involved in transporting magnesium into cells. That is why the Mg + B6 combination is found in supplements more often than magnesium on its own: B6 helps the body use the mineral it receives more efficiently.

If you already take other complexes containing magnesium or B6, take into account the total amount of these substances from all sources and, if necessary, consult a specialist.
