The #1 food that is highest in iron is clams, which provide you with around 24 mg of iron per 3 oz serving.
Iron fortified cereals are also the highest plant based foods and have up to 18 mg of iron per serving.
The most iron-dense foods are classified into heme, which are (highly absorbable, from animals) and non-heme (from plants).
The absolute best sources include organ meats (beef and chicken liver), shellfish (clams and oysters), fortified breakfast cereals, and dark chocolate.
Top Iron-Rich Foods by Category include:
1. Heme Iron (Easily absorbed)
Organ Meats: Chicken liver provides about 10.8 mg per 3 oz, while beef liver offers 5.2 mg per 3 oz.
Shellfish: Canned clams are incredibly high, delivering roughly 23.8 mg per 3 oz.
Oysters offer about 13.2 mg per 3 oz.
Red Meat: Lean beef chuck and lamb provide around 2–3 mg per 3 oz.
2. Non-Heme Iron (Plant-based) iron include:
Fortified Foods: Many ready-to-eat cereals and instant hot wheat cereals have high amounts added, ranging from 9 to 16 mg per cup.
Seeds and Nuts: Sesame seeds and pumpkin seeds are excellent, offering roughly 2 to 4 mg per small handful.
Legumes: Tofu, lentils, and white beans deliver between 4 and 13 mg per cooked cup.
Dark Chocolate: A 1-oz serving contains around 3.3 mg.
Dark Leafy Greens: Cooked spinach provides about 6.4 mg per cup.
It takes on average of 2 to 4 weeks to start raising your iron levels and begin feeling relief from the low iron symptoms, but it also takes between 3 months to 6 months of consistent iron supplementation to restore your body's stored iron (ferritin) levels fully.
During the first 1 to 2 weeks, your bone marrow will begin using extra iron to produce red blood cells, which can also slightly reduce dizziness and improve your energy.
1 to 2 months, your hemoglobin levels often return to a normal range and then 3 to 6 months is required to completely restock your body's iron stores and prevent relapse.
To maximize your iron absorption, take the iron pills with vitamin C such as with a glass of orange juice or a Vitamin C supplement to significantly enhance the iron absorption.
Don't take the iron supplements within 2 hours of consuming coffee, tea, "black or green tea", dairy, calcium supplements or antacids as these also block the body from absorbing iron.
Taking an oral iron supplement every other day is also just effective and can also reduce stomach upset.
Correcting an iron deficiency takes between 3 months to 6 months although the initial symptoms of the iron deficiency like headaches and fatigue often improve and get better within 2 weeks to 4 weeks of beginning treatments like oral iron pills or if needed an iron infusion.
Correcting an iron deficiency with oral iron supplements takes months and intravenous or IV iron infusions can fix iron deficiencies within 4 to 8 weeks.
Also treating the root issues of iron deficiencies, like gastrointestinal absorption problems or heavy menstrual bleeding is also crucial for long term recovery from iron deficiency.
The 5 unexpected signs of low iron are Pica, koilonychia or spoon nails, Restless Legs Syndrome, glossitis and Tinnitus.
These 5 unexpected signs of low iron include:
1: Pica or Unusual Cravings, which is a bizarre and compulsive desire of chewing on ice or even non food items like chalk, clay, paper or even dirt.
2: Koilonychia (spoon nails) is where your fingernails become incredibly brittle, thin and then eventually they dip inward in the middle so that they then resemble a tiny spoon.
3: Restless Legs Syndrome or RLS is an irresistible and uncomfortable urge to move your legs, especially occurring at night or when you're trying to sleep or relax.
4: Glossitis (Swollen or Smooth Tongue), is when your tongue becomes swollen, inflamed or unusually smooth and shiny as a result of the loss of natural bumps or "papillae", which is sometimes also accompanied by a burning sensation.
5: And tinnitus, where you experience a persistent ringing, humming or whooshing sound in your ears, which does not have an external source.
Iron is very important to the body and having a lack of iron in the body, prevents your body from producing hemoglobin, which is the protein in red blood cells that carry oxygen.
The lack of iron or low iron in the body can result in iron deficiency anemia and cause symptoms like brittle nails, pale skin, shortness of breath and fatigue.
lack of iron or low iron in the body is caused primarily by for main issues, which include blood loss, dietary deficiencies, poor absorption and increased demand.
Heavy periods or gastrointestinal bleeding like from ulcers or regular use of pain relievers.
Dietary deficiencies such as from not eating enough iron rich foods like poultry, red meat, fish, lentils and spinach.
Poor iron absorption such as from digestive conditions such as celiac disease or gastrointestinal surgeries, which impair nutrient absorption.
And even growth spurts in children or increased blood volume during pregnancy.
If you suspect you have an iron deficiency you should speak with your doctor to get blood tests done such as a serum ferritin test to diagnose the condition accurately.
Treatment for iron deficiency involves addressing the underlying cause of the blood loss or malabsorption, incorporating iron rich foods into your diet and or taking iron supplements.
