Does amla keep its vitamin C when cooked or dried?
Amla is one of the richest natural sources of vitamin C, a nutrient famous for being fragile. So does drying it, cooking it or making murabba destroy it all? Amla turns out to be an unusual case.
of vitamin C survives, unusually
Unlike most fruit, whose vitamin C is easily destroyed, amla keeps a surprising share of it through drying and cooking, shielded by its own tannins.1
Amla, the Indian gooseberry, has a reputation as a vitamin C powerhouse, and it earns it. But vitamin C is one of the most delicate nutrients there is, so surely the murabba, the dried candy, the pickle throw all of it away? Here amla breaks the usual rule.
A vitamin C giant
Amla is among the richest natural sources of vitamin C, far more, gram for gram, than an orange. That is the starting point, and it is a big one.
Vitamin C is normally fragile
In most foods, vitamin C is destroyed by heat, air, light and water. Boil a vegetable and much of its vitamin C ends up gone or in the cooking water. By that logic, dried or cooked amla should be nutritionally empty.
Amla’s trick: tannins
It is not, because amla is unusually rich in tannins and polyphenols that protect its vitamin C from oxidation. As a result, dried amla, amla powder, murabba and even the boiled fruit retain far more vitamin C than you would expect, studies repeatedly find unusually good retention.1
Fresh still wins, but processed counts
Fresh amla is still highest, so eat it in season. But the real lesson is that traditional amla preparations are not the waste of vitamin C you would assume, they are a genuine way to carry it through the year. And since vitamin C boosts iron absorption, amla alongside dal and greens does double duty (see the iron experiment).
Vitamin C retained after processing
amla vs a typical fruitAmla retains vitamin C unusually well thanks to its tannins; a typical fruit loses far more when cooked. Illustrative.1
What this means in your kitchen
Amla is worth eating in every form, in season and out.
- 1
Eat it fresh in season
Fresh amla or amla juice has the most vitamin C.
- 2
Keep dried amla and powder for the rest of the year
They retain far more vitamin C than most dried fruit.
- 3
Pair amla with iron-rich foods
Its vitamin C helps you absorb the iron in dal and greens.
- 4
Do not boil it to death
Gentle cooking keeps more, as with any vitamin-C food.
- 5
Count murabba and candy as real vitamin C
They are sweet, but not the empty sugar you might assume.
The myth
"Cooking or drying amla destroys its vitamin C, like any fruit."
The fact
Amla is unusual: its tannins shield the vitamin C, so a good share survives drying, murabba and cooking. Fresh is still highest, but processed amla is a genuine source.
How strong is the evidence?
We rate each claim separately, because they are not equally proven.
Amla is exceptionally high in vitamin C (Strong)
Well established; among the richest natural sources.
Its vitamin C is more heat- and storage-stable than typical (Emerging)
Repeatedly reported, attributed to its tannins.
Fresh amla retains the most (Strong)
As expected for any vitamin-C food.
"Processed amla has no vitamin C left" (Not supported)
Retention is unusually good.

In one minute
- Amla is a vitamin C giant, and, unusually, keeps much of it when dried or cooked.
- Its tannins protect the vitamin C that most fruit loses.
- Fresh is best, but murabba, powder and dried amla genuinely count.
