The slow evening pot of soup with an iron fish in it

The number that matters on this listing is 10 minutes, the time the fish sits in a pot of soup, stew, sauce or curry. The listing gives no milligram figure for the iron released, so the rest is claims about quality and safety rather than measurement.

The routine described is simple. For liquid meals such as soups, stews, sauces and curries, the Lucky Iron Fish goes into the pot for 10 minutes. For daily use, the listing describes making iron fortified water to drink or cook with, and mentions rice, oats, smoothies and ice as other ways to use that water. It calls the iron tasteless.

On materials, the listing says the iron is food grade, high purity and bioavailable, made in India by one of the world’s largest producers of food grade iron, and that it meets Food Chemical Codex (FCC) standards. It also says the product is patented, has been tested since 2012 and is supported by clinical trials. No trial results, iron amounts or test reports appear in the listing, so these remain statements by the seller. Phrases such as no side effects and gentle on the body are likewise claims, not figures.

The title mentions a 5 years supply, but the listing does not say how many uses that assumes, nor does it give dimensions, weight or care instructions. The seller also says a purchase helps undernourished communities receive their own fish. The item is sold in Oil and Leaf versions as well, and the listing text here does not describe how they differ.
