The short answer
Not known in people. Vitamin C helps the body absorb nonheme iron, the kind in plant foods, so amla could help iron absorption in theory. The one trial that came near the question did not test an iron tablet. It gave adults with anaemia plant iron from curry leaf, with or without vitamin C from amla, and haemoglobin rose more without the amla.
We found no study of amla taken with ferrous sulphate, ferrous ascorbate or any other iron medicine, so whether amla helps, hinders or does nothing is not known. If you take iron for anaemia, tell your prescribing doctor about any amla you take, and ask when your haemoglobin and ferritin will be rechecked.
Iron tablets sold in India include Orofer XT (ferrous ascorbate with folic acid).
At a glance
| What was seen | How it may work | Direction | Evidence |
|---|---|---|---|
| Vitamin C raises the uptake of nonheme iron[2] | Vitamin C makes nonheme iron easier to absorb | Could mean more iron absorbed; not tested with amla and an iron tablet | Theoretical by mechanism |
| Plant iron with amla vitamin C did not beat plant iron alone on haemoglobin[1] | Not established | Haemoglobin results do not add up; iron absorption not established | RCT |
No listing is not a clearance. A missing interaction here never means a combination is safe.
The evidence, study by study
Trial in iron-deficiency anaemia, Ahmedabad, 2025 RCT
Ninety-six adults with iron-deficiency anaemia were split into three groups for 60 days. One took 18 mg of plant iron from curry leaf (Murraya koenigii) with 90 mg of vitamin C from amla extract, one took the plant iron alone, and one took a placebo. Both iron groups improved over placebo. Haemoglobin rose from 10.26 to 11.60 g/dL with plant iron alone and from 10.23 to 11.11 with the amla combination, yet the authors describe the combination as better. The maker of both products, Orgenetics, paid for the study, and nobody in it took an ordinary iron tablet.[1]
Fact sheet, US National Institutes of Health Theoretical by mechanism
The NIH Office of Dietary Supplements lists vitamin C as a nutrient that enhances the absorption of nonheme iron. This is general nutrition science about vitamin C. It does not tell us how much vitamin C a given amla product delivers, or what amla does alongside an iron medicine.[2]
What your doctor may watch for
- Haemoglobin and ferritin, which show whether the iron is working. Your doctor decides when to recheck them.[2]
What to tell your prescribing doctor
You can read this out, or show them this page:
“I am taking, or planning to take, amla (fruit, juice, powder or capsules, and how much) along with my iron tablets. Amla contains vitamin C, which can affect iron absorption, but it has not been tested with iron medicines. When should my haemoglobin and ferritin be rechecked?”

Questions people ask
Does amla juice help iron absorption?
It might in theory, because vitamin C helps the body absorb plant iron. No study has measured iron absorption from a tablet taken with amla juice, and the vitamin C in juice and powders varies from product to product.[2][1]
Can amla treat anaemia on its own?
We found no evidence that it can. In the one trial that used amla, it was given only as a source of vitamin C alongside plant iron, and the group without amla did at least as well.[1]

Amla and blood pressure medicines
Two trials disagree. One found amla lowered blood pressure further in people on BP medicines; a larger one found no extra effect.
InteractionAmla and metformin
Amla lowered blood sugar further alongside metformin in one small rat study. Nobody has tested the two together in people.
InteractionTurmeric and iron supplements
A man on high-dose turmeric stayed anaemic on iron until he stopped it. A one-dose curcumin trial found no drop in iron absorption.
InteractionShilajit and iron tablets
Not studied in people. High-dose shilajit changed liver iron in rats, so it could add to iron tablets. How much is unknown.
