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.

This bag's own panel was not read, so it takes the 500 g bag's, and its servings per container is worked out rather than read: the 250 g net weight over that panel's 1/2 tsp (about 3.5 grams) serving. Not derived from the compound weight.

Alaska, Hawaii and Puerto Rico may incur extra charges by weight.
Cost per dose delivered
at least $0.148
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.

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.
