Clinical Research

Lucky Shakti Leaf is a clinically proven tool that helps improve iron levels naturally


Lucky Shakti Leaf is a redesigned version of the original Lucky Iron Fish. Both products are made using the exact same raw materials and from the exact same production facility. Clinical trials on the Lucky Iron Fish have been conducted by both the company as well as the researchers from 3rd party institutions like Harvard University, University of Göttingen, University of Pennsylvania, and more. These trials included:

  • Women of reproductive age– Infants (aged 1-5 years)
  • Families with school-aged children
  • Individual men, women and children in the developed world
  • People living with HIV.

Clinical research shows the Lucky Iron Fish is effective at improving iron stores in different groups of people across the world.

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.

This product is not intended to diagnose, treat, cure or prevent any disease. Carefully read all product documentation, and ask your healthcare provider if this product is right for you.
If you suspect that you have a medical problem, promptly contact your regular health care provider. Iron taken in excess can be harmful to both adults and children.
