Nutrient bioavailability depends not only upon the amount consumed, but also on how well it is absorbed. However, little is known about factors influencing Mg absorption. It is postulated that bound Mg may be absorbed better than in organic Mg (similar to heme iron and non-heme iron absorption).
The new magnesium (Mg) ICP-MS assays developed and validated by QPS are suitable for measuring the change in Mg concentrations in collected blood and urine samples after intake of oral magnesium solutions. Our clinical development consultants will be able to advise you as to the most suitable study design for determining Mg absorption.
