The best and quickest way to lower ferritin levels is to donate blood. He likely would need to first have the genetic test for hemochromatosis; he could still give blood but the purpose is decreasing his iron levels. Has he been tested for reasons for the high ferritin? Is his hemoglobin normal? Ferritin iron tends to store in organs, so can cause liver, kidney, or other damage. Some medicines that are metabolized through the liver and impact liver enzymes can also result in elevated ferritin. Bioavailable curcumin can help chelate the iron, and good to avoid red meat and other iron sources (such as some vitamins).

Here is one source on elevated ferritin levels https://www2.gov.bc.ca/gov/content/health/practitioner-professional-resources/bc-guidelines/iron-overload . Calcium can lower ferritin levels but don't know how much a person would need to take to make much of a difference. Is his blood calcium is within normal range? Calcium is better absorbed as calcium citrate.

It’s important to find the cause for this however before taking supplements. There can be underlying health reasons for ferritin levels to climb so it is best to have a physician support before trying to correct this issue with supplements.

Is your father currently working with his doctor to find the cause?
