To note:
Lucky Iron Fish is only effective when used regularly (at least 3 times a week) and the outlined instructions are followed.
It takes 3-6 months to see a clinical increase in iron status.
Used properly, the Fish does not cause side-effects because it is gentle on your digestive system. Clinical tests have also shown that the Lucky Iron Fish only alleviates iron deficiency and iron deficiency anemia; it does not improve anemia caused by other conditions (e.g. Thalassemia).
All the batches of Fish are tested to ensure that the iron released from the Fish is consistent and safe and that no other compounds are released that might be deleterious to health. The Lucky Iron Fish is approved for sale in countries around the world.
