About this ingredient
Magnesium is an essential mineral. Citrate and other salts contain both magnesium and the accompanying compound; their total weight is not the elemental magnesium amount.
Questions and answers
Why can too much supplemental magnesium be harmful?
It can cause diarrhoea and cramping. Very high levels can affect blood pressure, heart rhythm and breathing. Reduced kidney function can increase the risk of accumulation.
Does taking magnesium with manganese automatically make the combination unsafe?
A specific harmful interaction is not established by the fact that both are present. Assess each amount, total intake, kidney function and other medicines instead of treating all combinations alike.
What does the mass on a magnesium citrate label mean?
A stated citrate compound weight includes the citrate as well as magnesium. It must not be presented as the same number of milligrams of elemental magnesium.
