Among capsules, softgels and tablets, the cheapest is Core Med Science Magnesium Bisglycinate (60 capsules), at $0.40 before delivery ($17.99 a container). Among powders, the cheapest is BulkSupplements.com Magnesium Citrate Powder (1 kg), at $0.051 before delivery ($28.97 a container). Capsules and powders are ranked separately.
7 of the 94 magnesium products we track have their exact package named in NSF's Certified for Sport database. That is a stricter test than “the brand is NSF certified”, and it is deliberately so: NSF lists package sizes against each certificate, and a size it does not name is not one it has stood behind. Each price is delivered where the retailer publishes a delivery rate and before delivery where it does not, and each row says which. This page counts NSF's Certified for Sport database only, because its listings name the package size, which lets us check the exact package on sale. Informed Sport and Informed Choice list products rather than package sizes, a different way of answering the question rather than a lesser one.

Cheapest among the 7 magnesium packages we track that NSF names at the exact package, not the cheapest that exists. NSF certifies magnesium from more brands than we carry, and our catalog is extended brand by brand, so a certified product we have not added yet cannot appear here however cheap it is.

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.
