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.

Your daily amount in context
NRV is a labelling reference, not a personal target. The upper limit is not a quality rating. More is not automatically better. Basis: one serving per day assumed.

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.
Vitamin K matters for blood clotting. That does not mean every D3 product needs K2 or that K2 prevents vascular calcification.
What was studied
A randomized trial in 365 men with aortic valve calcification found no significant effect of MK-7 plus vitamin D on calcification progression after two years.
What remains uncertain
A biomarker is not proof of fewer heart attacks. Patient-group findings do not generalize to everyone. Vitamin K interacts with vitamin K antagonists such as warfarin.
Understanding the form
MK-4 and MK-7 are different forms. MK-7's longer persistence alone does not prove better clinical outcomes.
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.

Missing data is not a negative test result.
