The Nambu iron kettle provides iron (Fe2) which is absorbed straightly into our body. For the purpose, there is no coating layer inside of the kettle. If you boil water with the kettle for five minutes, you could take around 2mg of iron (data source: Nambu Tekki association website). The longer you use, the more iron you can take. The iron kettle also shows the best performance for chlorine removal among the other metal kettles (data source: Nambu Tekki association website).
The beautifully designed kettle will be a lovely kitchen interior, too. Enjoy the beauty and the health benefit from the product! The product is delivered in a black box.
