Lucky Iron Fish is a safe effective way to add iron to your diet. Our little Fish goes through lots of love care to get to you.

Check out our frequently asked questions below to learn more. 

How often should I use the Lucky Iron Fish?

The more you use the Lucky Iron Fish the more iron you are going to receive. Iron is absorbed slowly and in small quantities by the body. You need to use the fish regularly (every day if possible) over an extended period of time to see a beneficial effect. In clinical trials in Cambodia, the women reported that they were feeling better within 3 months of use and we saw positive changes in iron levels in the blood after 6 months of use.


How much iron does a Lucky Iron Fish release?

The Luck Iron Fish releases low levels of iron every time that it is used. The iron can be absorbed by the body and does not cause unpleasant side effects. The amount of iron that is released depends on the length of cooking time and the amount of acidity in the water. Typical use can release between2-7mg of iron. Most diets (not including red meat) have 5-10mg of iron. The daily recommended intake of iron varies by age, gender and stage of reproduction but on average the daily recommended intake is 14mg/day. Many iron supplements exceed the daily recommended intake which is why iron pills often have unpleasant side effects. We recommend that you boil the fish for 10minutes in 1 litre of water with 2-3 drops of the lemon juice.

How do I use it?

Simply boil the fish for 10 minutes in 1L of water with 2-3 drops of lemon juice (or anything acidic). The water can be stored for several days before drinking. To maximize the absorption of iron from the water, add a few drops of lemon juice before drinking the water. You can also cook the fish in soups or stews but for the best release of iron, these also need to have something acidic (lemon, tomato juice) added in the cooking process. After cooking with the fish or boiling it in water, make sure that you clean it with water. Dry the fish well and store it in a dry place.

Can I use it in things other than water?

For optimal results 1L of water with a bit of citrus is best. However other liquids like stocks will work but for the best release of iron you should add some citrus juice to the cooking pot. Just remember not to use the fish with coffee or caffeinated tea: both of these contain compounds that actually stop the body from absorbing iron from the diet.

Why not just use a cast iron pan?

Cooking in iron pots releases iron but it is difficult to determine how much is released and whether that iron can be absorbed by the body. Iron cooking pots and skillets tend to rust. Although rust is not harmful, it is ferric iron which is not well absorbed by the body. Many manufacturers of iron pots and skillets recommend that you 'seal' the pan by heating it at high temperatures with oil. 'Sealing' the pan blocks the release or iron during cooking. 

The Fish is made from a specific type of iron. Its shape, size and weight are calculated to release a consistent amount of iron that can be absorbed by the body every time it is used. For optimal results, we recommend that you boil 1 litre of drinking water with the Fish and 2-3 drops of citrus juice. You can also use apple vinegar to acidify the water.

How do I clean my fish?

We recommend that you clean your new fish before the first use and then immediately after use (but not too soon as it can be hot to touch!) with soap, warm water and a soft cloth. It is very important to dry the fish thoroughly.

When do I need to get new one?

There are families in Cambodia who were given a fish five years ago and they are still using them. Since then we have modified the design. Over time, as iron is leached off the fish into the cooking water, the features on its surface will wear down. We recommend that when the “smile” on your fish has faded it is time to buy a new one.

What are the signs and symptoms of iron deficiency?

The common signs of iron deficiency include general fatigue, weakness, pale skin, shortness of breath, dizziness, strange cravings to eat items that aren't food, such as dirt, ice or clay, a tingling or crawling feeling in the legs, and tongue swelling or soreness. 

How is iron deficiency diagnosed? How do I know I am iron deficient?

The typical way to diagnose iron deficiency anemia is to have your doctor complete tests to check for low iron levels and anemia. These possible tests include: a complete blood count (CBC) to look at the shape, colour, number and size of your blood cells; iron tests which measure the amount of iron in your blood, to help determine the severity of anemia; reticulocyte count, to help determine the cause of anemia; and a ferritin level test, which reflects how much iron may be stored in the body. Abnormally low ferritin levels may indicate iron deficiency anemia. 

How is iron deficiency treated?

There are a range of treatments of iron deficiency anemia depending on severity. Doctors will most likely recommend a change in diet, and iron supplementation. The Lucky Iron Fish is a safe and effective way to add iron to your diet. Please check with your doctor to see if the Lucky Iron Fish is right for you.


Is the fish safe?

Every batch of Lucky Iron Fish™ is extensively tested for safety and quality. We test to make sure that the fish releases iron that can be absorbed by the body at a level that will not cause toxicity. We also make sure that there are no contaminants in the iron that might be deleterious to human health. In addition to our regular testing, random spot tests by independent laboratories in Guelph, Ontario. The Bowmanville Foundry, where the international fish is manufactured, achieved ISO 9002 (International Organization for Standardization) certification in 1996 and undergoes re-audits by SGS International twice each year to ensure continuous improvement of all quality related systems.

Can anyone use the fish?

The fish is safe to use for everyone except people who have a genetic disorder that makes it difficult for the body to deal with iron. This genetic disorder is a serious condition known as hemochromatosis. If you are not certain or have any concerns, make sure that you consult your doctor before using the fish.    

Babies 0-6 months are exquisitely sensitive to iron and should not be given water cooked with the iron fish. Nursing mothers can use the Fish without negative impacts on the baby.

What kind of iron is it made from?

The Lucky Iron Fish is made from natural ferrous iron, which is easily absorbed by the body and is safe.

What if you have been diagnosed with Hemochromatosis?

If you have been diagnosed with hemochromatosis or are unsure about your iron levels we suggest speaking with a health care professional. Though the iron fish releases a small amount of iron per use it is important to stay informed!

Does it change the taste of the food?

No. The fish does not change the taste of the food. Adding lemon juice during the cooking or boiling process makes sure you have the best release of the iron from the fish.

Where are the Lucky Iron Fish made?

The Lucky Iron Fish is made at the Bowmanville Foundry, in Bowmanville, Ontario, Canada.

Where are you located?

We have an office in Phnom Penh, Cambodia, and in Guelph, Ontario, Canada.

What if there is rust on it?

The fish is made from iron and it will rust if kept in a damp place or not dried completely after use. Rust is not a problem: there are no negative effects on health but it may affect the taste and colour of food or water. If the fish is rusty, just clean it with lemon juice and the rust will come off.

What if the water changes colour?

Remember, it is important to make sure that the fish is clean before starting and that you boil the fish for 10 minutes with a little lemon juice added to the liquid. If your fish is not completely clean or you boil it for too long, this may affect the colour and taste of the water. In tests we have shown that you can boil the fish for long periods (even up to two hours) without risking toxicity but this will definitely colour the water and make it taste of iron. 

Can I cook with the fish in any container? What container should I use? What should I not use?

We have tested the fish in aluminum and glass pots. Providing the cooking pot can take boiling liquids it should be safe and effective.

How much does it cost to ship a fish to ……?

The fish is a bit heavy to ship – the ingot weighs almost 300g. Therefore shipping costs will range depending on location and shipping option selected. Typically the fish costs between $5-15 to ship.
