Can I Take Turmeric If I Have Anaemia?
Back to FAQsThe answer depends on the type and severity of your anaemia, as well as the form and dosage of turmeric you're considering. For the most common form — iron deficiency anaemia — turmeric supplements are generally not recommended and may actually be harmful.
The Science Behind It
Curcumin, the active compound in turmeric, binds to iron in the digestive tract through a process called iron chelation. Research shows that turmeric can inhibit iron absorption by 20% to 90% in humans, in a dose-dependent manner. This means the more you take, the more it blocks your body from absorbing dietary iron.
The Exception
For certain types of anaemia caused by iron overload — such as beta-thalassemia or sickle cell disease — turmeric's iron-binding property may actually be beneficial. Some research suggests curcumin could help reduce excess iron in these specific conditions. However, this should only be explored under strict medical supervision.
Supplements vs. Food
This is where the distinction matters most.
- High-dose supplements carry the highest risk. A documented case reported a 66-year-old man who developed significant iron deficiency anaemia after taking six turmeric extract capsules (538 mg each) daily. His haemoglobin, iron, and ferritin levels all returned to normal within two weeks of stopping the turmeric.
- Culinary use (as a spice in cooking) is generally considered safe, as the amounts involved are far smaller than those found in supplements.
Final Recommendation
Always consult your doctor before taking any turmeric supplement if you have anaemia. This is especially important if you're already taking iron supplements or blood-thinning medications, as turmeric can also increase bleeding risk.
If you are correcting an iron deficiency with a supplement like Chelon (ferrous bisglycinate equivalent to 30 mg elemental iron, with vitamin C to aid absorption), the same timing rule applies: keep concentrated turmeric well away from your iron dose so the chelated iron can absorb fully.
A Quick Anecdote: What About Turmeric in Curries?
"If turmeric blocks iron, should I avoid eating curries?"
The short answer is no — curries are perfectly safe. Here's why:
- The dose is tiny: A typical serving of curry contains about ¼ to ½ teaspoon of turmeric powder. Since turmeric is only 2% to 5% curcumin, a whole serving gives you just 10 to 50 milligrams of curcumin. Turmeric supplements typically contain 500 to 1,000 milligrams of concentrated curcumin — you'd have to eat dozens of bowls of curry daily to match that dose.
- Poor absorption: Curcumin is notoriously difficult for the body to absorb. Even with black pepper (which boosts absorption), the amount reaching your gut is minuscule compared to a concentrated supplement.
- The rest of the meal helps: Curries are often packed with vitamin C–rich ingredients like tomatoes, lemon juice, or amchur (dried mango powder) — all of which enhance iron absorption. Plus, if your curry contains iron-rich foods like legumes, lentils, or meat, the iron content of the meal far outweighs what the tiny amount of turmeric could bind.
The only rule: If you're taking prescription oral iron supplements, avoid taking the pill at the exact same time as a turmeric-heavy curry. Separate them by 2 to 3 hours to ensure the concentrated iron absorbs fully, while you enjoy your curry as a delicious, healthy meal.
