9 of the 75 products whose panel we have read name more than one salt. A Supplement Facts panel has to say which compounds the magnesium comes from. The product name does not, and the two do not always agree.

This is not an accusation of mislabeling. The panel is the legally binding statement and it discloses the blend correctly; it is the product name that does not. It matters because a blend can reach the same elemental figure with a different mix of salts than the name suggests, and because someone choosing one salt specifically is choosing it over whatever else is on the panel.

Where to buy: the pick for each type
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
