Is Buffalo Milk Healthier Than Cow's Milk?

Buffalo milk has nearly double the fat of cow's milk, significantly more calcium and protein — and it is naturally A2. Here's what that means nutritionally, who it suits, and when cow's milk is the better choice.

Buffalo milk has been a dietary staple across South Asia, Italy, and the Middle East for centuries. In the UK it is best known as the basis for authentic mozzarella di bufala, but it is increasingly appearing in whole-food shops, online retailers, and artisan dairy aisles as a fresh milk alternative.

The claims that accompany it range from the accurate — it is more nutritious than cow's milk — to the overstated — it is categorically healthier. The honest comparison is more interesting and more useful than either framing suggests.

TL;DR

• Buffalo milk contains approximately double the fat of whole cow's milk (7 to 8% versus 3 to 4%), significantly more protein, 30% more calcium, and considerably more phosphorus and magnesium.
• It is more energy-dense — approximately 97 calories per 100ml compared to around 61 calories in whole cow's milk.
• Buffalo milk is naturally A2 — it contains only A2 beta-casein protein, not the A1 protein present in most commercial cow's milk. A2 protein is associated with fewer digestive symptoms in people sensitive to A1 protein.
• The higher fat content makes buffalo milk more satiating but less suitable for people managing calorie intake or cardiovascular risk factors.
• Buffalo milk is not universally healthier — it is more nutritionally dense, which is beneficial in specific contexts and less so in others.
• In the UK, buffalo milk is available through specialist retailers and online but is considerably less accessible and more expensive than cow's milk.

How Buffalo and Cow's Milk Actually Compare

The nutritional difference between buffalo and cow's milk is more significant than most people realise. Per 100ml:

Buffalo milk (approximate)

• Calories: 97 kcal
• Fat: 7 to 8g
• Protein: 4 to 4.5g
• Calcium: approximately 32% of daily value
• Phosphorus: approximately 41% of daily value
• Magnesium: approximately 19% of daily value
• Vitamin A: approximately 14% of daily value

Whole cow's milk (approximate)

• Calories: 61 kcal
• Fat: 3 to 4g
• Protein: 3.2g
• Calcium: approximately 21% of daily value
• Phosphorus: approximately 29% of daily value
• Magnesium: approximately 6% of daily value
• Vitamin A: approximately 12% of daily value

The differences are meaningful. Buffalo milk provides approximately 40% more protein and 58% more calcium than cow's milk per equivalent volume. It is also significantly higher in phosphorus and magnesium — two minerals that, alongside calcium, are central to bone density maintenance.

What cow's milk tends to do better: it provides more vitamin B12 and vitamin D per serving, and its lighter composition makes it easier to digest for people with sensitive stomachs or lower fat tolerance.

The A2 Protein Distinction: The Most Interesting Difference

This is the aspect of buffalo milk that is most relevant to people who experience digestive discomfort from conventional cow's milk — and the least discussed in standard nutrition comparisons.

Beta-casein is one of the primary proteins in milk. It comes in two main variants: A1 and A2. Most commercial dairy cattle — particularly Holstein Friesians, which dominate UK dairy farming — produce milk containing both A1 and A2 beta-casein, with A1 predominating.

When A1 beta-casein is digested, it releases a peptide called beta-casomorphin-7 (BCM-7). BCM-7 is an opioid peptide that has been associated with digestive discomfort — slowed gut transit, bloating, and inflammation — in some people, and has been linked in observational research to type 1 diabetes risk and cardiovascular markers, though these associations are contested.

Buffalo milk is naturally A2 — it contains only A2 beta-casein, not A1. Clinical trials have found that A2 beta-casein milk alleviates gastrointestinal symptoms of milk hypersensitivity, increases intestinal beneficial bacteria including Bifidobacterium, and improves Bristol stool scores compared to A1 beta-casein milk.

The practical implication: people who experience bloating, digestive discomfort, or what they believe to be mild lactose intolerance from regular cow's milk may actually be reacting to A1 beta-casein rather than — or in addition to — lactose. Switching to buffalo milk, which is naturally A2, may resolve these symptoms in ways that standard lactose-free cow's milk does not.

This is distinct from true lactose intolerance — buffalo milk contains slightly more lactose than cow's milk, not less. If lactose itself is the problem, buffalo milk will not help and may worsen symptoms.

Fat Content: More Satiating, More Calorie-Dense

The most significant practical difference between buffalo and cow's milk for most UK consumers is the fat content — and it cuts both ways.

Buffalo milk's higher fat slows gastric emptying — the rate at which food leaves the stomach. This makes it more satiating than cow's milk for equivalent volumes. A glass of buffalo milk will keep hunger at bay for longer than an equivalent glass of whole cow's milk. This makes it useful in contexts where sustained satiety is the priority — alongside a meal with a long gap to the next one, or in a high-protein dietary context.

The calorie density is the other side of that equation. At approximately 97 calories per 100ml versus 61 calories for whole cow's milk, buffalo milk provides roughly 60% more energy per glass. For people managing calorie intake, those additional calories add up meaningfully across regular consumption.

For cardiovascular health, the picture is similarly nuanced. Buffalo milk has higher saturated fat content than cow's milk, which raises questions about cardiovascular risk for people with elevated LDL cholesterol or established cardiovascular disease. This does not make buffalo milk harmful for most healthy adults, but it is a relevant consideration for specific populations.

Calcium and Bone Health

Buffalo milk's substantially higher calcium content — approximately 32% of the daily value per 100ml versus 21% for cow's milk — makes it genuinely useful for people with higher calcium requirements.

Children, adolescents, postmenopausal women, and older adults all have elevated calcium needs for bone density maintenance. The additional calcium phosphorus and magnesium in buffalo milk provide meaningful nutritional support for bone health that goes beyond what cow's milk delivers.

For reference, a 200ml glass of buffalo milk provides approximately 64% of the daily recommended calcium intake — nearly two-thirds of the daily requirement in a single serving. This makes it a particularly efficient calcium source for people who struggle to meet requirements through diet alone.

The caveat: the higher calorie density means that maximising calcium from buffalo milk comes with a calorie cost that may not be appropriate for everyone.

What Buffalo Milk Is Best For

Higher protein needs — athletes, people recovering from illness, older adults managing muscle preservation, and growing children all benefit from the higher protein density of buffalo milk. At 4 to 4.5g per 100ml versus 3.2g in cow's milk, a daily glass of buffalo milk provides meaningfully more protein.

Digestive sensitivity to A1 protein — people who experience bloating or discomfort from conventional cow's milk that is not resolved by lactose-free alternatives may benefit from buffalo milk's natural A2 composition. This is worth trialling as a diagnostic as much as a permanent switch.

Bone health and calcium requirements — postmenopausal women, older adults, teenagers in growth phases, and anyone with low bone density who wants to maximise dairy calcium intake.

Cooking and dairy products — buffalo milk's higher fat and protein content make it significantly better than cow's milk for producing rich, creamy dairy products. It is the standard milk for authentic mozzarella di bufala, and produces richer yoghurt, cheese, and cream.

What Cow's Milk Is Better For

Calorie management — whole cow's milk provides substantially fewer calories per serving, making it more appropriate for people managing overall energy intake.

Easy daily digestibility — cow's milk is lighter and easier to digest for most people, particularly children, the elderly, and those with compromised digestion. The lower fat content means faster gastric emptying.

Cardiovascular risk management — semi-skimmed or skimmed cow's milk provides the calcium and protein benefits of dairy with reduced saturated fat — a combination that buffalo milk cannot match.

Cost and accessibility — in the UK, buffalo milk is a specialist product available primarily through online retailers, farm shops, and specialist food stores. It is considerably more expensive than cow's milk. For everyday daily use, the price and accessibility difference is practically significant.

Buffalo Milk in the UK: Where to Find It

Buffalo milk is produced in the UK — most notably at the Laverstoke Park Farm in Hampshire and Denmore Farm in Yorkshire — and is available through online delivery, farm shops, and some specialist retailers. It is considerably less available than cow's milk and typically commands a premium price.

For most UK consumers, buffalo milk is a specialist choice for specific nutritional purposes or culinary use rather than a direct everyday replacement for cow's milk. Mozzarella di bufala — widely available in supermarkets — provides some of the nutritional benefits of buffalo milk in a more accessible and affordable format, though with the concentrated fat content of cheese rather than milk.

Frequently Asked Questions

Is buffalo milk healthier than cow's milk?

Neither is categorically healthier — they have different nutritional profiles that suit different needs. Buffalo milk is more nutritionally dense — higher in protein, fat, calcium, and phosphorus — making it beneficial for people with higher nutritional requirements, those who experience A1 protein sensitivity, and contexts where calorie density is an advantage. Cow's milk is lighter, easier to digest, lower in calories, and considerably more accessible and affordable for everyday use.

Is buffalo milk A2?

Yes — buffalo milk naturally contains only A2 beta-casein protein, not the A1 protein present in most commercial cow's milk. A2 beta-casein has been associated with fewer digestive symptoms than A1 in clinical trials. This makes buffalo milk worth trying for people who experience bloating or discomfort from conventional cow's milk that is not resolved by lactose-free alternatives.

Does buffalo milk have more calcium than cow's milk?

Yes — significantly more. Buffalo milk provides approximately 32% of the daily calcium value per 100ml compared to 21% for cow's milk. A 200ml glass of buffalo milk provides approximately 64% of the recommended daily calcium intake. It also contains substantially more phosphorus and magnesium — the other minerals central to bone health.

Is buffalo milk suitable for lactose intolerance?

No — buffalo milk contains slightly more lactose than cow's milk. People with true lactose intolerance will not find buffalo milk easier to tolerate and may find it harder. People who experience digestive discomfort from cow's milk related to A1 protein sensitivity rather than lactose may find buffalo milk easier to tolerate, as it is naturally A2.

Can you get buffalo milk in the UK?

Yes — it is produced at farms including Laverstoke Park Farm in Hampshire and available through online retailers, specialist food stores, and farm shops. It is considerably less available and more expensive than cow's milk, making it more appropriate as a specialist dietary choice than an everyday replacement.

Is buffalo milk good for children?

Buffalo milk's higher protein and calcium content makes it nutritionally advantageous for growing children with high nutritional requirements. However, its higher fat and calorie content means it should be used in appropriate serving sizes rather than consumed in large volumes as a primary fluid source. Whole cow's milk remains the standard recommended dairy option for children in UK dietary guidance.

The Bottom Line

Buffalo milk is more nutritionally dense than cow's milk — more protein, more calcium, more fat, more calories. That makes it better suited to specific contexts: higher nutritional needs, A1 protein sensitivity, bone health optimisation, and rich dairy product production. It does not make it universally healthier than cow's milk, which remains the more practical, accessible, and versatile choice for everyday use.

The most practically useful aspect of buffalo milk for UK consumers is probably its natural A2 composition — worth considering for anyone who has been unable to trace their dairy-related digestive discomfort to lactose alone.
