Cheapest Iron-Rich Foods, Ranked by Cost Per Milligram

Spinach gets the headlines, but it's one of the most expensive ways to hit your iron target. Ranked by cost per milligram rather than just "iron content," a different set of foods comes out on top.

Haem vs Non-Haem Iron — Why It Matters

Not all iron is equal. Haem iron (from meat, fish, poultry) is absorbed at 15–35% efficiency. Non-haem iron (from plants, eggs, legumes) is absorbed at only 2–20% efficiency — but you can dramatically improve this with the right food combinations.

This means 5mg of iron from chicken liver is worth far more than 5mg of iron from spinach. Use the table below with that in mind.

Cheapest Iron-Rich Foods — Ranked by Iron Per Dollar

Prices based on Coles & Woolworths homebrand, May 2026. RDA reference: adult female 19–50 (18mg/day).

Food	Iron per serve	Cost/serve	% RDA (women)	Type
🫀 Chicken liver (100g)	9 mg	$0.90	50%	Haem
🥩 Lamb liver (100g)	8.7 mg	$1.20	48%	Haem
🫘 Lentils, cooked (1 cup)	6.6 mg	$0.25	37%	Non-haem
🥣 Weet-Bix (3 biscuits, fortified)	4.5 mg	$0.25	25%	Non-haem
🫘 Kidney beans, canned (½ cup)	3.0 mg	$0.30	17%	Non-haem
🥩 Kangaroo mince (100g)	3.2 mg	$1.50	18%	Haem
🐟 Sardines, canned (1 tin)	2.9 mg	$1.50	16%	Haem
🥩 Beef mince (100g)	2.7 mg	$1.80	15%	Haem
🍳 Eggs (2 large)	1.8 mg	$0.80	10%	Non-haem
🥦 Broccoli (1 cup cooked)	1.0 mg	$0.70	6%	Non-haem
🌿 Spinach (1 cup cooked)	3.6 mg	$0.50	20% (on paper)	Non-haem*

*Spinach contains oxalates that block iron absorption — effective uptake is much lower than the label suggests. Pair with vitamin C to partially compensate.

💡 Best value iron food in Australia

Chicken liver at ~$5/kg gives you 9mg of highly-absorbed haem iron per 100g serve — that's 50% of a woman's daily requirement for under $1. It's genuinely the most iron-dense food per dollar available at any Australian supermarket.

Absorption Rules That Can Double Your Iron Uptake

What you eat with your iron-rich food matters as much as the iron content itself.

✅

Eat vitamin C with non-haem iron — vitamin C converts iron into a form your body absorbs up to 3× more efficiently. Add capsicum, citrus juice, tomato, or broccoli to bean dishes, lentil curries, and fortified cereals.

✅

Eat haem iron alongside non-haem iron — a small amount of meat with a bean-based meal boosts iron absorption from the beans significantly ("meat factor").

❌

Avoid tea and coffee within 1 hour of iron-rich meals — tannins in tea and chlorogenic acid in coffee block non-haem iron absorption by up to 60%. This is one of the most common hidden causes of low iron in Australians.

❌

Don't take calcium supplements with iron-rich meals — calcium competes with iron for absorption. If you take calcium supplements, take them at a different time of day.

❌

Phytates in wholegrains reduce plant iron absorption — soaking and sprouting legumes and grains reduces phytate content. Cooking lentils from dry (rather than canned) and adding lemon juice helps.

Iron-Rich Budget Meal Ideas

These combinations maximise iron intake and absorption without blowing the food budget:

Chicken liver stir-fry with broccoli and capsicum — ~$1.50/serve, 9mg+ iron, vitamin C boosts absorption
Lentil and tomato soup — ~$0.55/serve, 6.6mg iron, tomato's vitamin C helps uptake
Weet-Bix with orange juice instead of milk (at breakfast) — the vitamin C in OJ boosts iron absorption from the fortified cereal
Lamb liver with roast sweet potato and capsicum — ~$2/serve, 8.7mg haem iron
Sardines on toast with tomato — ~$2/serve, 2.9mg haem iron plus omega-3
Beef and bean chilli — combines haem iron (beef) with non-haem iron (beans) for the "meat factor" effect

Signs of Iron Deficiency

Iron deficiency can develop slowly and is often missed. Common signs include:

Persistent tiredness and low energy — even after adequate sleep
Pale skin, pale inner eyelids
Shortness of breath during normal activity
Brittle nails, hair loss
Difficulty concentrating ("brain fog")
Restless legs at night
Craving non-food items like ice or dirt (pica) — a classic iron deficiency sign

⚠️ Get a blood test first

If you suspect iron deficiency, ask your GP for a full iron study (ferritin, transferrin saturation, serum iron) — not just a haemoglobin check. Ferritin below 30 µg/L is considered deficient even if haemoglobin is normal. Don't self-prescribe iron supplements — too much iron is harmful. Food-first is always the safest approach.

Who Needs More Iron?

Group	Daily Iron Needed	Why
Women 19–50	18 mg	Monthly blood loss
Pregnant women	27 mg	Foetal blood production
Breastfeeding women	9 mg	Lower (menstruation paused)
Men 19+	8 mg	Baseline maintenance
Adolescent girls 14–18	15 mg	Growth + menstruation onset
Vegans & vegetarians	1.8× the standard RDA	Non-haem iron less bioavailable
Endurance athletes	30–70% higher	Foot-strike haemolysis, sweating
