This site's own materials state this directly: magnesium can be a problem in kidney disease — worth understanding exactly why.
Kidneys are responsible for clearing excess magnesium from the body — impaired kidney function can lead to magnesium building up to levels that carry their own health risks, distinct from the general medication-interaction cautions already covered.
If you have diagnosed kidney disease or reduced kidney function, talk to your doctor before starting a magnesium-containing supplement like this one, rather than assuming it's automatically safe because it's a common mineral.
Go in informed — verify the label, the price and the refund terms, and talk to your doctor if you take medication.
