Which Vitamin D3 product has the lowest cost per 1,000 IU?
NatureWise Vitamin D3 5000 IU — $0.01 per 1,000 IU, based on 5,000 IU 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 Vitamin D3 products?
By the labeled Vitamin D per serving, read from the reviewed label, then normalized to cost per 1,000 IU. 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 Vitamin D3 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.
