Upper intake level
Adults, 350mg a day, from supplements and medications; magnesium in food does not count toward it. One serving of this product holds 400mg, more than that level on its own.
An upper intake level is the largest daily intake unlikely to cause harm for most people. It is not a limit on treatment. Higher amounts are sometimes used, but only under the direction and supervision of a health care provider. It is not a recommendation about what to take.

Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $36.04 below the $59.00 threshold, and this retailer does not publish a rate, so we cannot tell you what it will add. Free delivery on orders over $59 within the contiguous US. Below that, the rate is calculated at checkout and is not published in advance. Alaska, Hawaii and Puerto Rico may incur extra charges by weight.
Cost per dose delivered
at least $0.128
We will not put a number on this. The product price is a floor, not the price you will pay. Reaching the free-delivery threshold, or choosing a retailer that publishes its rate, is the only way to know in advance.

Ordered by price, lowest first, and labeled so you can see what each link earns us. Commission is never an input to that ordering. If the cheapest retailer pays us nothing, that is still the one we send you to. No link on this page earns us anything; every Buy button is a plain retailer link.

Verification, Tier A?: Independently certified, package unconfirmed
A certification program lists this product, but its listing does not name the package size priced here, so we do not present it as an unqualified certification. The listing, and exactly what it does and does not cover, is set out below.
- NSF Certified for Sport lists this product, but the listing does not cover the package size shown here. NSF listing 1791472 names the 1 kg powder package only, as read by Dan. The 360-capsule bottle priced here is a different form of the same salt and is not on the listing, so the certification is shown as scope-unconfirmed rather than as covering this package.

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. Found an error? Tell us. The full method: How we compare.
