A2 vs A1 Ghee: What Really Differs, and Which to Buy
A2 vs A1 ghee: the difference is a milk protein, and ghee keeps almost none of it. A teaspoon of ghee holds about 14 mg of milk protein of every kind together, and the digestion trials that favour A2 were done with milk, not ghee. Pay for A2 ghee because of the cows and the kitchen behind it, not for protein in the spoon. We make A2 Gir cow ghee, so read our view with that in mind.
Is A2 ghee better than A1 ghee?
Not in the spoon. A1 and A2 are two forms of beta-casein, a protein in cow's milk, and FSSAI requires ghee to be at least 99.5% milk fat. So both jars are the same fat with the same 44 kcal a teaspoon. Where A2 ghee earns its price is in what usually comes with it: named Indian cows and slower curd-made ghee.
Daily teaspoon on roti, dal, khichdi
A2 cow ghee from a named breed and the curd method, for the herd and the kitchen behind it, not for protein in the spoon.
Milk gives you gas or loose stools
Try A2 milk before you blame ghee. Ghee has almost no protein of either kind.
Milk protein allergy
Neither. A2 is still milk protein. An allergist decides about any ghee.
Deep-frying pakora and puri
Neither. Use a cooking oil and keep ghee for the finish.
Buffalo ghee
The question does not apply: all buffalo milk tested is A2.
This page is for the reader weighing the A1 and A2 science before paying more. What the A2 label may and may not mean on a jar is on what is A2 ghee.
What are A1 and A2 in milk, and which cows give each?
A1 and A2 are two versions of beta-casein, one of the main proteins in cow's milk, and a cow's genes decide which she makes. When A1 beta-casein is digested it can release a small piece called BCM-7 (beta-casomorphin-7), which is why A1 milk is blamed for gut trouble. A2 does not release it in the same way.
Indian breeds are mostly A2. Khan and colleagues (Animal Biotechnology, 2023) tested 1,000 milk samples from seven Indian breeds and two foreign ones. In the Indian breeds, 80% of cows carried two A2 genes and none carried two A1 genes. Gir scored highest, with 93% of cows A2A2. In Jersey and Holstein-Friesian, only 3% were A2A2 and 42% were A1A1. A crossbred cow can inherit either form.
How Gir and Sahiwal compare on these tests is on Sahiwal ghee vs Gir ghee. Buffalo are simpler: a 2021 study of 657 buffaloes found every one A2A2, so the A1 question is only ever about cow ghee.
How much A1 or A2 protein is left in ghee?
About 14 mg of milk protein in a 5 g teaspoon, of all kinds together, and beta-casein is only part of that. USDA FoodData Central lists butter oil (ghee) at 0.28 g of protein per 100 g, and whole milk at 3.15 g. The casein leaves with the milk solids that brown and are strained off when the butter is cooked.

That last row is the point most A2 ghee pages skip. The milk trials below gave people 750 ml of milk a day, about 24 g of milk protein. To eat that much protein from ghee you would need about 1,700 teaspoons. The USDA ghee figure comes from a single old sample, so treat 14 mg as a size, not a lab result for your jar. Where the protein goes step by step, and what that means for milk allergy, is on does ghee have casein.
We see this in the kitchen. The makkhan is ready to come off the chulha when the bubbling goes quiet and the milk solids at the bottom of the matki turn golden-brown. Those brown bits are where the protein went. An undercooked batch stays cloudy, keeps moisture and solids, and spoils fast, so it never goes in a jar.
What do the A1 vs A2 milk trials show?
Some trials found more gut discomfort on A1 milk, a 2026 trial found none, and no trial we found tested ghee. Most were paid for by The a2 Milk Company, which sells A2 milk.
Ho et al., European Journal of Clinical Nutrition, 2014
41 adults, 750 ml of milk a day, 2 weeks on each milk
Firmer stools on A1 milk, and belly pain tracked stool changes only on A1. The authors called it preliminary.
Jianqin et al., Nutrition Journal, 2016
45 adults in China who said milk upset them
More gut discomfort and slower transit on ordinary (A1 and A2) milk than on A2-only milk. Funded by The a2 Milk Company; one author worked there.
Greenway et al., Nutrition Journal, 2026
50 adults in the US who said milk upset them
No significant difference in symptoms, stools, transit time, or blood and stool tests between the two milks. Sponsored by The a2 Milk Company.
Küllenberg de Gaudry et al., Nutrition Reviews, 2019 (review)
15 controlled trials plus other studies, to October 2017
Moderate certainty that A1 milk causes more digestive symptoms than A2 milk; low or very low certainty for every other health claim.
Read together: there is a fair signal that some people who feel unwell after milk do better on A2 milk, and it is not settled. The 2019 review rated the evidence on other claims, such as heart disease and diabetes, as low or very low. None of it tells you about a teaspoon of ghee, which carries a tiny fraction of the protein those people drank.
Does A2 ghee help digestion or lactose intolerance?
Not because it is A2. If ghee upsets you, the cause is more likely the amount, the rest of the meal, or a badly cooked jar that kept milk solids, than the protein type.
Lactose, the milk sugar, also leaves with the solids and the water, so well-made ghee of either kind is very low in it. A2 does not remove lactose; cooking does. How much ghee to eat with lactose intolerance is on A2 ghee and lactose intolerance. If milk itself gives you trouble, switching your milk to A2 is the swap the trials actually tested.
A milk allergy is different. A2 beta-casein is still milk protein. If milk has ever caused hives, swelling, vomiting, or breathing trouble, ask an allergist before eating any ghee, A1 or A2. Ongoing belly pain, blood in stool, or weight loss needs a doctor, not a new jar; see ghee and IBS.
Is "A2" on a ghee label allowed in India?
Yes, for now. In an advisory dated 21 August 2024, FSSAI told food businesses that A1 and A2 differ only in protein structure and that A2 claims on milk-fat products such as ghee were misleading, as All India Radio News reported. On 26 August 2024 it withdrew the advisory "for further consultation and engagement with stakeholders".
So A2 on a jar is legal, and it describes the herd, not the ghee. In our Ghee Lab claims report (September 2026), 9 of 38 ghee packs put A2 in the product name, and 2 of those are buffalo ghee, where every jar is A2 anyway. Our own cow jar is one of the 9.
A2 vs A1 ghee side by side
The rows that differ are the cows and the price; the ghee itself is the same fat. No pack in India sells itself as "A1 ghee", so the right-hand column is the cow ghee most homes already buy.
A2 ghee vs A1 (regular) cow ghee
| Factor | A2 cow ghee | A1 or regular cow ghee |
|---|---|---|
| Which cows | Indian breeds such as Gir, Sahiwal, Tharparkar; Gir tested 93% A2A2 | Foreign breeds such as Holstein-Friesian and Jersey, and their crosses; 97% of the foreign cows tested carried at least one A1 gene |
| Protein that differs | A2 beta-casein | A1 beta-casein, which can yield BCM-7 when digested |
| Milk protein in a teaspoon of ghee | About 14 mg, all kinds together | About 14 mg, all kinds together |
| Fat and calories | At least 99.5% milk fat; about 44 kcal a teaspoon | At least 99.5% milk fat; about 44 kcal a teaspoon |
| Trials on ghee itself | None found | None found |
| Price per litre (our index) | Curd cow ghee median ₹2,399 | No jar says A1. Dairy cow ghee median ₹720 |
| Price per teaspoon | About ₹12.0 | About ₹3.6 |
Verdict: The protein gap is real in milk and tiny in ghee. What you pay for with A2 curd ghee is the herd and the method.
Khan et al., Animal Biotechnology, 2023; USDA FoodData Central; FSSAI Chapter 2.1 (2023); Ghee Price Index, September 2026. Checked 27 September 2026.
Our own Gir cow ghee is ₹2,399 a litre, about ₹12.0 a teaspoon. The 13 dairy cow ghees in the index ranged from ₹616 to ₹1,651 a litre; most name no breed, so their milk could be any mix of Indian, crossbred, and foreign cows. Every brand's price is in our Ghee Price Index.
Is A2 ghee worth paying more for?
Yes, if you eat it by the spoon and the jar tells you which cows and which method. No, if you only want a frying fat.
Choose A2 cow ghee if
- You eat ghee straight: on roti, in dal, on khichdi. You taste the milk and the cooking there.
- You want to know the breed and where the cows are, and A2 with a named breed tells you that.
- The jar is also made from curd, which is where most of the extra price goes.
Skip the A2 premium if
- You want it for deep-frying. Use a cooking oil; the A2 protein is not in the fat anyway.
- You hope it will fix a medical problem. No trial shows that for ghee.
- The jar says A2 and nothing else: no breed, no place, no method.
Three kitchens, three answers
"Chai gives me gas, so should I buy A2 ghee?"
Change the milk first. The trials tested A2 milk, and even 50 ml of milk in a cup of chai holds over 100 times the protein of a teaspoon of ghee. Keep ghee to a teaspoon on a meal and see how you feel.
A parent picking ghee for a toddler's dal
Pick pure, fresh cow ghee from a maker who shows the cows and the method. The A2 label is fine but not the reason. Amounts by age are on ghee for toddlers.
Pakoras for guests
Fry in oil and pour a spoon of ghee on the dal instead. Why oil suits the kadai is on ghee for deep frying.
Mistakes people make with A2 ghee
- Paying A2 prices for a jar that names no breed and no method.
- Believing A2 ghee has "no cholesterol" or "heals the gut". It is the same fat, and no trial tested ghee.
- Eating more because A2 sounds lighter. A teaspoon is 44 kcal either way; see calories in ghee.
- Paying extra for "A2 buffalo ghee". All buffalo milk is A2.
- Taking A2 as a sign of the curd method. A2 names the cow; Bilona names the method, and a jar can have one without the other. The two routes are on Bilona ghee vs cream ghee.
How to check an A2 ghee label: 6 points
Save this before you buy. A2 is only as good as the seller behind it.
- 1 The label names the cow breed. "A2" or "desi cow" with no breed tells you little.
- 2 The seller says where the cows are, somewhere you could visit.
- 3 The method is written out: milk set to curd, churned, then cooked. "Traditional" alone says nothing.
- 4 The FSSAI licence number is printed and checks out on foscos.fssai.gov.in.
- 5 The jar makes no cure claim, such as "A2 ghee heals the gut" or "no cholesterol".
- 6 The price makes sense for curd ghee: ₹2,399 a litre was the median for curd cow ghee in our index. Far below that, ask how.
Then check the ghee itself: smell, grain, and a warm spoon, on how to identify pure ghee. If you are choosing between Gir ghee and a dairy jar, the full comparison is on Gir cow ghee vs regular ghee.
Which A2 ghee do we keep at home?
Our cow jar says A2 because every cow batch is Gir cow milk, the breed that tested highest for A2 in the 2023 study. We have not gene-tested our own cows, so we will not claim more than the breed. What we can show is the rest: Gir cows and partner farmers' cows in Gir Somnath, grazing near the Gir forest, no hormone injections. The milk is set to curd overnight, churned for 30 to 45 minutes, and the makkhan is cooked in a matki on a wood chulha. Our cow ghee ranking, with other brands, is on best cow ghee in India.
We make both jars below, so weigh our view with that in mind. Our A2 Gir cow ghee is for the spoon on roti and dal, and our Jafarabadi buffalo ghee, A2 like all buffalo ghee, is for sweets and parathas. Both are cooked after you order, with a video of your jar on WhatsApp. We test every month against the FSSAI limits, and anyone can visit; see how we make ghee.

FAQ
Which is the best A2 ghee to buy in India?
We rank our own A2 Gir cow ghee first, and we make it, so weigh that. It is Gir cow milk from Gir Somnath, set to curd, churned, and cooked on a wood chulha after you order, with a video of your jar on WhatsApp. Other curd ghees that name Gir milk on their own pages in September 2026 include GirOrganic, Gavyamart, Rosier, and Anveshan. Check each against the label points above.
Is buffalo ghee A1 or A2?
A2. A 2021 study in Tropical Animal Health and Production tested 657 buffaloes of four breeds and every one carried only the A2 form of beta-casein; the authors conclude A1 does not exist in buffalo. So "A2 buffalo ghee" on a label is true of every buffalo jar, the cheapest included. Choose buffalo ghee on milk, method, and freshness instead.
Can I test at home whether ghee is A1 or A2?
No. No kitchen test, smell, colour, or grain tells A1 from A2. The difference is a cow gene, found by a DNA test of the animal or its milk, as the 2023 Indian breed study did with milk samples. Ghee has too little protein left to test that way at home. What you can check is the breed named, the method, and the seller.
Is Amul ghee A1 or A2?
Amul's own pages do not say. Its regular cow ghee names no breed, so the milk could come from any mix of Indian, crossbred, and foreign cows. Amul also sells a Gir Cow Ghee pack, per its own page in September 2026, without an A2 claim. Either way, a teaspoon of any ghee holds about 14 mg of milk protein, so the answer matters less than the milk and method.
Does A2 ghee raise cholesterol less than A1 ghee?
No study shows that. A1 and A2 are proteins, and ghee is at least 99.5% fat, so the fat that affects blood lipids is the same kind in both jars. The 2019 review rated the evidence for any non-digestive A1 effect as low or very low. If you watch your cholesterol, the amount of ghee matters, whichever cow it came from.
Is A2 ghee better for babies and children?
No trial has tested A2 against regular ghee in children. For a child over one year, a teaspoon of pure, fresh cow ghee stirred into dal, rice, or khichdi, counted within the family's fats, is the usual Indian way. The breed matters less than purity and amount. Do not start ghee for a baby under one without asking your paediatrician.
