Which Magnesium product has the lowest cost per 100 mg elemental Mg?
Nature's Bounty Magnesium 500 mg — $0.01 per 100 mg elemental Mg, based on 500 mg elemental Mg per serving at the current listed price. This is arithmetic from the label and price, not a ranking of quality or effectiveness.
How does BasisTrace compare Magnesium products?
By the labeled Elemental Mg per serving, read from the reviewed label, then normalized to cost per 100 mg elemental Mg. Serving sizes, forms and package sizes are converted to the same unit so the numbers line up. Missing disclosures are marked as unavailable, never counted as zero.
Does BasisTrace lab-test the Magnesium products?
No. Labeled amounts are transcribed from reviewed labels with a linked source and a review date. BasisTrace does not run independent laboratory testing and does not verify bottle contents — every number is the label's claim, not a test result.
