We track 13 magnesium malate products, but every one is a combination — magnesium malate comes alongside other ingredients and the label's single dose belongs to whichever one the product is built around. We can't say what magnesium malate alone costs per dose in them, so we rank nothing here rather than publish a figure we'd have to invent. See all 13 on the magnesium malate page, or the ranked magnesium they are usually sold with.
We link primary sources and paraphrase their findings — never copy their text, tables, or images. Cost-per-dose figures are our own first-party catalog data.
