Almond milk vs cow milk: the carton decides the calcium

The strongest trial evidence on this page is about neither drink as it comes off the shelf. A meta-analysis of 65 randomized trials tested milk protein as a supplement of casein or whey rather than a glass of milk. In adults it lowered systolic blood pressure by 1.99 mmHg (95% CI -3.16 to -0.82), total cholesterol by 4.03 mg/dL and triglycerides by 6.11 mg/dL, with no change in LDL, HDL or diastolic pressure. Almond milk has no synthesis of randomized trials at all. On the question most shoppers care about, calcium, the carton decides. In USDA Foundation Foods sampling, unsweetened almond milk ran from 7.477 to 289 mg per 3.5 oz (100 g) across 14 retail samples, while whole cow milk ran from 116 to 130 mg across 11. The bottom of the almond range is an unfortified carton rather than a measurement error, so one calcium number for almond milk describes only part of the shelf. Only one trial has put the two drinks head to head in people. In 22 adults with type 2 diabetes and overweight or obesity, almond milk served with oatmeal gave no difference in four-hour glucose response against carbohydrate-matched or calorie-matched 2 percent cow milk, on a single open-label test day.

How much is actually in it

• In USDA Foundation Foods sampling, calcium in unsweetened almond milk ranged from 7.477 to 289 mg per 3.5 oz (100 g) across 14 samples, while whole cow milk ranged from 116 to 130 mg per 3.5 oz (100 g) across 11 samples. — retail samples analyzed for USDA Foundation Foods, release 2026-04-30 (n = 14 almond milk samples and 11 whole milk samples) Evidence E source

Safety, limits and interactions

• Cow milk protein allergy is one of the most common food allergies in infancy, and across six controlled studies fecal short-chain fatty acid levels in affected infants pointed in opposite directions. — infants diagnosed with cow milk protein allergy, six studies with control groups, published July 2011 to October 2025 (n = 6 studies) Evidence C source

Who this works differently for

• By a meta-analysis of 5 randomized trials in 369 adults aged 60 and over, dairy intake raised global cognition with a standardized mean difference of 0.45. — adults aged 60 years and over, 22 studies reviewed, 5 randomized trials meta-analyzed (n = 369) Evidence A source

What is still unknown

• Laboratory data suggest that across 171 reviewed studies plant-based milks still show nutritional inadequacy, off-flavors and phase instability as barriers to replacing dairy. — 171 peer-reviewed studies of plant-based milks and beverages from legumes, cereals, nuts, seeds and blends (n = 171 studies) Evidence D source
  Low protein content in cereal-based beverages and off-notes in legume bases persisted after fermentation, enzymatic hydrolysis, high-pressure processing and ultrasonication

The bottom line

A cup of unsweetened almond milk weighs 8.6 oz (244 g) in the USDA survey table, so a real glass carries about two and a half times the per 3.5 oz (100 g) figures above. Absorption is where cow milk still has an answer. The NIH Office of Dietary Supplements puts calcium absorption at about 27 percent from milk and about 30 percent from dairy products and fortified foods as a class, against 5 percent from spinach. Almond milk itself was not measured there, so how much calcium you take up from a fortified carton is unknown. One safety card exists and it belongs to the cow. Cow milk protein allergy is among the most common food allergies of infancy. A review of six controlled studies of affected infants found fecal short-chain fatty acids higher in two studies and lower in three, with one study reporting no values, and that marker is not a symptom anyone feels. We have no card on almond allergy, so if you avoid tree nuts, read nothing reassuring into that silence. Nothing on this page is about feeding infants or young children either: the one infant card describes cow milk protein allergy itself, not what belongs in its place, and the plant-based milk review here records nutritional inadequacy as an open problem. Two marketing lines have been filed and refused. The EU register lists the claim that cow milk products support dental health as non-authorized, and the claim that 0.99 oz (28 g) of almonds a day helps maintain healthy blood cholesterol as non-authorized, one of three almond claims filed and none approved. Non-authorized means the evidence did not reach the bar at assessment. For adults over 60, a meta-analysis of 5 randomized trials in 369 people found dairy raised global cognition with a standardized mean difference of 0.45 (95% CI 0.30 to 0.60). The observational arm of the same review found nothing (OR 0.95, 95% CI 0.89 to 1.02). That randomized total is tiny and almond milk was not in it. The only retention row that reaches this page is a Beverages-group entry for an alcoholic beverage stored overnight without heat, assigned 100 percent retention for calcium and vitamin B12. Neither almond milk nor cow milk has a row of its own, and 100 percent there records that losses were never measured rather than that nothing is lost. Across 171 reviewed studies of plant-based milks, laboratory work still reports low protein, off-flavors and phase instability. We found no trial comparing almond milk with cow milk on bones, fractures or blood lipids beyond that one four-hour test.

   The absorption of calcium from dairy products and fortified foods is about 30% [1]. Certain compounds in plants (e.g., oxalic acid, phytic acid) can decrease calcium absorption by forming indigestible salts with calcium [3]. As a result, absorption of calcium is only 5% for spinach, whereas it is much higher, at 27%, for milk [3].
