Magnesium Citrate: Well Absorbed, and a Gentle Laxative
Magnesium citrate is magnesium bound to citric acid. Of the forms that absorb well, it’s usually the cheapest, which makes it the sensible default if all you want is a top-up. The US National Institutes of Health lists citrate among the forms that dissolve well and are better absorbed than magnesium oxide.
One trait defines it: it loosens the bowels. At everyday doses many people notice nothing at all. Push the dose and it becomes a reliable laxative, which is exactly why pharmacies also sell it for occasional constipation. Decide which of those two jobs you’re hiring it for, and dose accordingly.
Best for: a well-absorbed daily top-up on a budget; occasional constipation.
Be cautious if: you have kidney problems (speak to a doctor first) or take regular medication, as magnesium can interact with some drugs.
