High ferritin levels are treated by removing excess iron from the body, most commonly through regular blood draws called therapeutic phlebotomy. Normal ferritin ranges are 15 to 300 ng/mL for men and 15 to 200 ng/mL for women, and the typical treatment goal is to bring levels down to between 50 and 150 ng/mL. The right approach depends on what’s causing the elevation, how high your levels are, and whether you can tolerate blood removal.
Why Ferritin Gets Too High
Ferritin is a protein that stores iron inside your cells, so a high reading usually signals too much iron in your body. The most common genetic cause is hereditary hemochromatosis, a condition where your intestines absorb more iron than you need from food. But high ferritin doesn’t always mean iron overload. Liver disease, chronic inflammation, infections, and certain cancers can all push ferritin up without an actual surplus of stored iron. Alcohol use is another common driver: even mild to moderate drinking has been shown to increase the prevalence of iron overload, partly because alcohol doubles the rate of iron absorption in the gut.
This distinction matters because the treatment changes depending on the cause. If inflammation is behind your elevated ferritin, phlebotomy won’t help, and addressing the underlying condition is the priority. Your doctor will typically check your transferrin saturation (a measure of how much iron is actively circulating) alongside ferritin to figure out whether true iron overload is present.
Therapeutic Phlebotomy
Phlebotomy is the primary treatment for iron overload. It works the same way as donating blood: about 500 mL (roughly one pint) is drawn per session. Each session removes 200 to 250 mg of iron and lowers serum ferritin by approximately 30 ng/mL.
During the initial phase, sessions are typically scheduled weekly or biweekly until ferritin drops into the target range of 50 to 150 ng/mL. How long this takes depends on how high your starting level is. Ferritin often declines noticeably within the first few months, though iron saturation markers can take closer to a year to normalize. In cases with significant liver iron accumulation, the full course of treatment may stretch to a year or longer of regular sessions.
Once your ferritin reaches the target range, you shift to maintenance. This usually means one session every two to six months, adjusted based on repeat blood work. The goal during maintenance is to keep ferritin between 50 and 150 ng/mL with transferrin saturation below 45 percent. Many people with hereditary hemochromatosis stay on a maintenance schedule for life.
Iron Chelation Therapy
Some people can’t tolerate phlebotomy, either because of anemia, heart problems, or poor vein access. Others have iron overload caused by conditions that require repeated blood transfusions, like thalassemia, sickle cell disease, or myelodysplastic syndrome. In these cases, medications called iron chelators are used instead. These drugs bind to excess iron in the body so it can be excreted through urine or stool.
Three iron chelators are FDA-approved. One is given by injection or infusion and has been in clinical use since the 1980s. The other two are oral tablets, which are more convenient for long-term use. Your doctor selects one based on the underlying condition, how well you respond, and side effect profile. Chelation therapy is a cornerstone of managing transfusion-dependent anemias and has significantly reduced the complications of iron overload in these patients.
Dietary Changes That Lower Iron Absorption
Diet alone won’t fix significant iron overload, but it plays a meaningful supporting role alongside medical treatment, and for people with mildly elevated ferritin, it can make a real difference.
Foods to Limit
Heme iron, the type found in animal blood and muscle, is absorbed much more efficiently than the iron in plant foods. Red meat from mammals is the biggest dietary source. Organ meats (liver, kidney, heart), blood sausage, and game meat are especially high because game animals are not bled after being killed, leaving all the blood iron in the tissue. If your ferritin is elevated, switching to lean white poultry is a practical swap.
Shellfish like mussels, oysters, crab, and lobster are also iron-rich and worth limiting. Raw shellfish carry an additional risk: they can harbor Vibrio vulnificus, a bacterium that causes severe infections, particularly in people with liver disease or iron overload. All shellfish should be thoroughly cooked.
Foods and Drinks That Block Iron Absorption
Certain compounds in food naturally reduce how much iron your gut absorbs, and you can use this strategically. Tea, coffee, cocoa, and red wine contain polyphenols and tannins that bind to iron in your digestive tract, forming complexes your body can’t absorb. The effect is dose-dependent: the more you drink with a meal, the greater the inhibition. Population studies in Denmark found that men who drank more coffee and tea had significantly lower iron stores.
Calcium also inhibits iron absorption and is one of the few substances that reduces uptake of both heme and non-heme iron. Dairy products consumed with meals can help blunt the iron you absorb. Phytic acid, found in whole grains, legumes, and nuts, has a similar blocking effect on non-heme iron. Eggs and soy protein also inhibit absorption.
Timing matters. These inhibitors work best when consumed during the same meal as iron-containing foods, since they act inside the gut before iron crosses into the bloodstream.
Supplements and Substances to Avoid
Vitamin C powerfully enhances non-heme iron absorption, which is helpful for people with iron deficiency but counterproductive when ferritin is already high. If you’re dealing with iron overload, avoid high-dose vitamin C supplements, especially around meals. Getting vitamin C from whole fruits and vegetables in normal amounts is less of a concern, but megadose tablets (500 mg or more) could meaningfully increase the iron you absorb from food.
Iron supplements are an obvious one to stop, but also check your multivitamin. Many formulas contain iron, and continuing to take one while trying to lower ferritin works against your treatment.
Why Cutting Alcohol Matters
Alcohol has a uniquely harmful relationship with iron. It suppresses hepcidin, the hormone your liver produces to regulate iron absorption. When hepcidin drops, your intestines ramp up the proteins that pull iron from food into your bloodstream. The result is that your body absorbs iron as if it were deficient, even when stores are already high. Studies in chronic alcohol users show a two-fold increase in intestinal iron absorption compared to non-drinkers.
This effect compounds over time. Alcohol also causes oxidative stress in the liver, which further disrupts hepcidin signaling. Reducing or eliminating alcohol removes one of the strongest dietary accelerators of iron accumulation, and in animal studies, antioxidant treatment reversed alcohol’s effect on hepcidin entirely. For anyone with elevated ferritin, limiting alcohol is one of the highest-impact lifestyle changes available.
What the Treatment Timeline Looks Like
If you’re starting phlebotomy with very high ferritin (say, above 1,000 ng/mL), expect the initial depletion phase to take several months to over a year of regular sessions. At roughly 30 ng/mL reduction per session, someone starting at 1,000 ng/mL and drawing weekly would need around 30 sessions to reach the target range. In practice, the pace varies: some people tolerate weekly draws while others need longer gaps to recover their red blood cell counts.
Ferritin tends to drop relatively quickly in the first few months. Transferrin saturation, which reflects circulating iron rather than stored iron, is slower to normalize and may take a year or more. Liver iron accumulation, visible on MRI, can show marked improvement after about three years of consistent treatment. Blood work is repeated regularly throughout to adjust the schedule.
The good news is that phlebotomy is well tolerated by most people. Side effects are similar to donating blood: occasional lightheadedness, fatigue, or bruising at the draw site. Staying hydrated before sessions and eating a meal afterward helps. Over time, as iron stores come down, many people notice improvements in joint pain, fatigue, and liver function that were subtly driven by excess iron.
