Is pistachio milk high in calcium?

Only if it's fortified. The pistachios themselves are a modest calcium source (about 105 mg per 100 g of nuts, roughly 29 mg in a 1-oz serving), and a glass of pistachio milk contains only a small fraction of that. Brands that fortify with calcium carbonate or tricalcium phosphate can reach around 300 mg per cup, similar to cow's milk; homemade and unfortified versions have very little. The amount is set by what the brand adds, not by the nut.

Does pistachio milk have as much calcium as cow's milk?

A fortified pistachio milk can. Cow's milk provides roughly 300 mg of calcium per 8-oz cup, and label figures for fortified pistachio milk land in a similar range. But this only holds for products that are actually fortified. Read the panel, because exact amounts vary by brand and by sweetened versus unsweetened or barista lines, and some pistachio milks add little or no calcium.

Does homemade pistachio milk have calcium?

Very little. Homemade pistachio milk is just blended pistachios, water and sometimes a pinch of salt or sweetener, so its only calcium is the small amount carried from the nuts, far below a glass of milk. If you make your own and rely on plant milk for calcium, you'd get most of your calcium from other foods or choose a fortified retail product instead.

Is Pistachio Milk a Good Source of Calcium?

Q: Is the calcium in fortified pistachio milk well absorbed?

Reasonably. Harvard's Nutrition Source notes that dairy calcium is absorbed at about 30%, and that some fortified non-dairy options have calcium amounts and bioavailability similar to milk. A calcium-fortified pistachio milk can therefore be a sensible contributor, provided the brand fortifies and you actually drink the labeled amount. Shake the carton, since added calcium can settle.

Whether pistachio milk is a good source of calcium comes down to one word: fortification. Unfortified pistachio milk, including everything you make at home, is a poor calcium source, because the nut itself is only modestly rich in calcium and the milk is mostly water. Fortified retail brands, on the other hand, add calcium and can match cow's milk. The number you want lives on the Nutrition Facts panel, not in the pistachio.

How much calcium is in pistachios themselves?

Pistachios are a modest, not rich, calcium source. USDA FoodData Central lists raw pistachios at 105 mg of calcium per 100 g of nuts. That sounds reasonable until you scale it to a real serving: a typical 28 g (1 oz) handful provides only about 29 mg, and 100 g of nuts is still just around 8% of the FDA's 1,300 mg Daily Value for calcium. So even eating pistachios by the bowlful wouldn't make them a standout calcium food. They're prized for unsaturated fats, protein and minerals like potassium instead.

Why unfortified pistachio milk is low in calcium

Because a glass of pistachio milk is mostly water. A cup contains only a fraction of an ounce of nuts, so the calcium carried over from the pistachios alone is small, on the order of a few tens of milligrams per cup at most. This is the same dilution that keeps the milk low in calories and modest in protein: most of the nut, by weight, doesn't end up in the carton, and homemade versions strain out the solids too.

The honest framing is this: any pistachio milk that meaningfully contributes calcium gets that calcium from fortification, not from the nuts. If you blend your own pistachio milk at home, treat it as a near-zero calcium drink and get your calcium elsewhere.

How much calcium is in fortified pistachio milk?

Quite a lot, by design. Brands fortify plant milks with calcium carbonate and/or tricalcium phosphate, and reported label figures for fortified pistachio milk land around 300 mg of calcium per 8 fl oz cup, roughly 23% of the 1,300 mg Daily Value. That's comparable to cow's milk, which provides about 300 mg per cup across whole, 2% and skim.

Per 1 cup (8 fl oz)	Calcium	≈ %DV (1,300 mg)
Fortified pistachio milk	~300 mg	~23%
Cow's milk (whole / 2% / skim)	~300 mg	~23%
Unfortified pistachio milk (Three Trees Organic Unsweetened, label, Aug 2026)	45 mg	~3%
Homemade pistachio milk	low (tens of mg)	low
Raw pistachios, 1 oz (28 g)	~29 mg	~2%

Approximate; varies by brand and by sweetened vs unsweetened or barista line. The ~300 mg figure is a brand-specific label value, not a universal property of pistachio milk. Read the exact carton.

The big limit: this only applies to products that are actually fortified, and the amount varies by brand and even by line within a brand. Sweetened, unsweetened and barista versions can differ. So the figure above is a guide to what fortified products can deliver, not a promise about any glass of pistachio milk. When we compiled every published US panel for our pistachio milk nutrition facts page in August 2026, the spread ran from 45 mg to 280 mg a cup, and the carton with the shortest ingredient list was the low one. If calcium matters to you, scan the panel before you buy. It is the same diligence that helps when picking the best pistachio milk or where to buy it.

Is added calcium in plant milk well absorbed?

Reasonably, yes. Harvard's Nutrition Source notes that calcium from dairy is absorbed at about 30%, and that some fortified non-dairy options, such as calcium-fortified orange juice and calcium-set tofu, provide calcium amounts and bioavailability similar to milk. A calcium-fortified pistachio milk can therefore be a sensible everyday contributor, with two practical conditions: the brand has to fortify, and you have to actually drink the labeled amount.

That second point is easy to miss. Added calcium can settle to the bottom of the carton, so giving it a good shake before pouring helps you get closer to what the label promises. It's a small habit that makes a fortified milk do its job.

How calcium pistachio milk fits your day

For context, the FDA Daily Value used on labels is 1,300 mg, while the Harvard Nutrition Source and NIH list adult RDAs of 1,000 mg/day for women 19-50 and men 19-70, rising to 1,200 mg for women 51+ and men 71+. Against those numbers, a cup of fortified pistachio milk at ~300 mg is a genuine contribution, roughly a quarter to a third of an adult's daily target, but it is not, on its own, a calcium plan. It works best as one of several calcium sources alongside greens, dairy or other fortified foods. The broader picture is in pistachio milk benefits and is pistachio milk good for you.

If you or someone you feed falls into a group that leans heavily on plant milk for calcium, such as young children, during pregnancy, postmenopausal women, or anyone at risk of low bone density, don't assume pistachio milk covers it. Choose a fortified product, read the panel, and speak to a doctor, dietitian or health visitor (or follow NHS / NIH guidance) about meeting calcium needs, rather than relying on any single drink.

Allergy note

Pistachios are a tree nut, so pistachio milk is unsuitable for anyone with a nut allergy, even though it is dairy-free and vegan-friendly. This is general nutrition information, not personalized dietary advice; calcium content varies by brand and line, so check the current Nutrition Facts panel, and consult a qualified professional about your own calcium needs.

Allergy note: Pistachios are a tree nut. If you have a nut allergy, avoid pistachio milk and pistachio products, and check labels for cross-contamination warnings. This article is general information, not personalized dietary or medical advice.
