Cost
- The panel prints "Magnesium (as Magnesium Citrate) 400 mg 95%" per serving of 2 tablets. Elemental magnesium is the comparison basis here and the panel states it directly, so 400 mg is read off the label rather than computed; the panel prints no weight for the citrate compound, so none is recorded and nothing is derived from one. The calorie, carbohydrate, fiber and sodium lines the panel also prints are nutrition facts rather than a second active, and nothing is priced on them. This panel prints its own "Servings Per Container 30" line, and 30 servings of 2 tablets is the 60 tablets the front face prints.

Set the quantity at the retailer; this calculator does not add items to a cart. Uses the recorded unit price with no coupon or quantity discount. Tax is extra. Delivery terms apply to the contiguous US unless the policy says otherwise.
Delivery terms and limits
Free shipping within the contiguous United States on orders of $25 or more before tax, and a flat $8 fee below that, from Nature Made’s own shipping policy page read September 23, 2026 and again on October 17, 2026: "Free shipping within the contiguous U.S. is available on: Orders $25+ (before tax)" and "A flat $8 shipping fee applies to: Orders under $25". Shipments outside the contiguous United States, including Alaska and Hawaii, carry the same $8 fee. The page calls neither term temporary. It also says some products or state requirements may add cost, shown at checkout, so a delivered total can be higher than these two figures describe.
Where to buy
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.

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.
