Undeclared quantities remain unknown. Ingredient order or a total amount does not establish the amount of each form.
Recorded nutrient amounts per serving
Declared nutrient amounts and values calculated from compound quantities are identified separately. Mass fraction is not a quality or efficacy judgment.

Look at the magnesium amount and its chemical form. Better absorption alone does not prove better sleep or performance.
What was studied
A randomized study in 46 healthy people compared citrate, oxide and an amino-acid chelate: citrate showed better absorption measures.
What remains uncertain
Absorption markers are not health outcomes. Small studies do not establish superiority for every product or person.
Understanding the form
NIH reports that citrate, chloride, lactate and aspartate are often better absorbed than oxide. We give no bonus to malate, taurate, orotate, threonate or other forms without direct comparative evidence. Elemental fraction is not bioavailability.
Results apply to the tested sample. They do not prove efficacy or automatically verify the batch currently sold. PortionCheck does not conduct its own laboratory testing.
