Each format is priced as its own range, never against another; capsules include softgels and tablets.
Two things move the price and neither is the brand alone: which salt the panel names, because the salts carry very different amounts of magnesium by weight, and the package, since a powder sold by the kilogram and a bottle of capsules are not the same purchase. A product whose panel names a second salt is marked. The salts are not interchangeable, so the cheapest row is a price, not a recommendation. Every figure is per 200 mg elemental magnesium as each product's own Supplement Facts panel states it, before delivery; each product page says whether its retailer publishes a delivery rate.

200 mg elemental magnesium is the unit this site prices magnesium against, so that packages of different strengths and forms can be compared at all; it is not a recommendation about what to take. The cheapest at each type, with the salts side by side: What is the cheapest magnesium per dose?
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.
