*You may have noticed the value of calcium in almond milk is 0. We thought that was strange too, but it turns out virtually all the calcium in almond milk is added by the manufacturer. You can read more about these “fortified milks” toward the bottom of this page.

Cow’s Milk

Cow’s milk has been the go-to source of calcium for decades. And despite the surge in popularity of milk alternatives, cow’s milk still dominates milk sales in the United States. Reports show that dairy milk raked in $16.2 billion in 2017, and cow’s milk makes up the vast majority of that figure.

How much calcium is in cow’s milk?

Whole, 2%, 1%, and skim milk all provide similar amounts of calcium per cup –– about 300 mg. For reference, the recommended daily intake of calcium is 1,000 mg for women under 51 and men under 71. For women over 51 and men over 71, it’s 1200 mg.

Pros of Cow’s Milk Cons of Cow’s Milk

High in calcium

Lots of people are allergic to cow’s milk. Most commonly it’s because of two specific proteins– casein and whey

It contains 18 of 22 essential nutrients in one convenient glass

Not suitable for a lot of people with dietary restrictions or choices

Very versatile ingredient

Questionable practices. There are concerns over how some dairy farms produce cow’s milk

Almond Milk

Pros of Almond Milk Cons of Almond Milk

Very low in sugar and fat

Very little natural calcium and protein content

100% vegan

Not suitable for people with nut allergies

Contains no lactose. And lactose could be bad for your bones.

Often contains a lot of unnatural sweeteners (look out for unsweetened varieties)

Rice Milk

Rice milk is a naturally sweet alternative to cow’s milk. It’s made by blending partially milled rice with water. And during this process, the carbohydrates in the rice break down into sugars. That’s where the sweetness comes from!

On a less sweet note, rice milk tends to contain traces of arsenic. You see, arsenic is present in the environment, and rice absorbs more of it than other cereal crops. So it’s advised that infants and toddlers shouldn’t consume rice milk.

How much calcium is in rice milk?

Rice milk contains about 283 mg of calcium per cup. Not far off the 300 mg of calcium per cup cow’s milk provides!

A cup of rice milk also contains:

  • 0.67 grams of protein
  • 2.33 grams of fat
  • 12.67 grams of sugar
  • 22.01 grams of carbohydrates
  • 113 calories
Pros of Rice Milk Cons of Rice Milk

One of the least allergenic milk alternatives

Provides very little protein

Naturally sweet flavor

Not suitable for infants

Low in fat

Contains a lot of carbohydrates, so may not be suitable for diabetics

Soy Milk

As the name suggests, soy milk comes from soybeans. The milk is produced by soaking and grinding the beans and boiling the mixture. The final step is filtering the liquid to produce the end product.

Research shows that soy milk delivers the most balanced nutritional value of all cow milk alternatives! Plus, soy milk is naturally lactose-free. So it’s a great alternative for people who are lactose-intolerant. But unsweetened soy milk is an acquired taste, especially for people used to the taste of cow’s milk. Plus, soybean is the most genetically modified crop in the world! In fact, 94% of soy acreage in the United States is genetically modified. And genetically modified organisms (GMO) are linked with health and environmental issues. So if you opt for soy milk, it’s best to go organic — as organic means it’s also non-GMO!

How much calcium is in soy milk?

Soy milk only contains 300 mg of calcium per cup.

A cup of soy milk also contains:

  • 9.00 grams of protein
  • 4.51 grams of fat
  • 1.99 grams of sugar
  • 4.01 grams of carbohydrates
  • 91 calories
Pros of Soy Milk Cons of Soy Milk

Lactose-free

Soy is a common allergen

The most balanced nutritional value of all cow milk alternatives

An acquired taste

Contains lots of isoflavones, which improve blood pressure

Most soybean crops in the United States are genetically modified

Coconut Milk Beverage

Coconut milk in a drinking sense is often referred to as coconut milk beverage. And it’s different to the canned coconut milk you might have used before in the kitchen. Both are made from the white, fleshy part of a mature, brown coconut. (Coconut water comes from unmatured green coconuts). The flesh of the coconut is shredded, simmered in water, and strained. The mix then separates into a rich, creamy layer and a liquid layer beneath. These two layers together are what you’ll find in canned coconut milk for cooking. But for coconut milk beverage, the creamy layer is skimmed off.

Now, coconut milk contains a lot of unsaturated fat compared to other types of milk. But it’s not all bad news! Coconut milk contains a type of fat called medium-chain triglyceride. And studies show this type of fat can help prevent obesity. So with all that in mind, consider using this type of milk in moderation.

How much calcium is in coconut milk?

Coconut milk contains a modest amount of calcium naturally. But like other milk alternatives, calcium-fortified options are available.

A cup of coconut milk also contains:

  • 0 grams of protein (this is also a common addition to fortified options)
  • 4.01 grams of fat
  • 0.0 grams of sugar
  • 1.99 grams of carbohydrates
  • 45.6 calories
Pros of Coconut Milk Beverage Cons of Coconut Milk Beverage

Contains healthy fats that can promote weight loss

The high-fat content can be an issue if consumed in large quantities

Fortified options often contain high amounts of vitamins A and D

Provides very little calcium and protein naturally

Coconut isn’t actually a nut, so allergies aren’t a common issue

Some of the thickening agents in coconut milk can cause digestive issues for some people

Goat Milk

You might not think of goats when it comes to milk sources, but outside the Western world, goat’s milk is widely consumed! And as far as nutritional value goes, goat’s and cow’s milk are very similar. In fact, the calcium values are pretty much identical. Goat’s milk also tends to be easier to digest than cow’s milk too, because it has smaller protein particles and contains less lactose.

How much calcium is in goat’s milk?

Goat’s milk contains 300 mg of calcium per cup. That’s the same as cow’s milk.

A cup of goat’s milk also contains:

  • 7.99 grams of protein
  • 2.50 grams of fat
  • 10.99 grams of sugar
  • 10.99 grams of carbohydrates
  • 101 calories
Pros of Goat’s Milk Cons of Goat’s Milk

Easier to digest than cow’s milk

Very distinct smell and taste

High in calcium

Harder to come by in supermarkets and is often expensive as a result

Less allergenic than cow’s milk

 

Fortified Milks

You may remember we mentioned fortified milks a little earlier on this page. So what are they exactly, and what do you need to know about them?

Well, fortified milk is a milk product the manufacturer has added an essential nutrient to. Cow’s milk is typically fortified with vitamins A and D.

Vitamin A is fat-soluble, and is naturally present in cow’s milk. But vitamin A is lost during the production of skim or skimmed milk, so it’s actually a legal requirement to add it to these products. As for vitamin D, it helps your body to absorb the calcium your consuming in the milk.

It’s not just cow’s milk that can be fortified, though. The alternative milks we’ve discussed on this page are often fortified too. But these fortified milks contain added calcium to make their nutritional value similar to that of cow’s milk. Is it too good to be true though? Check out the video below to see if fortified milks are a good source of calcium…


The Calcium Content of Other Dairy Products

There’s one glaring thing to consider with milk…

While it’s useful to know the calcium content of milk, the average adult rarely drinks a whole glass of it. We use milk more sparingly as we get older– in a morning bowl of cereal, as a cooking ingredient, or a splash or two in a cup of coffee or tea. But the average adult often consumes dairy in the form of cheese or yogurt.

So how much calcium do you get from these dairy products?

Well, as far as cheese is concerned, the runaway winner in calcium content is parmesan. It provides 1268 mg per 100 g (although it’s usually consumed in far smaller quantities.)

And plain old yogurt provides anywhere between 154-176 mg of calcium per 100g. To discover the calcium content of other dairy products (including your favorite cheeses) check out our “Top Calcium-Rich Foods Post.”


The Takeaway

When it comes to the calcium content of milk, cow’s and goat’s milk provide the most bang for your buck (300 mg per cup). For people that can’t drink dairy because of allergies or dietary restrictions, milk alternatives like soy and almond milk are available.

These milk alternatives do offer certain benefits, but they tend to be lacking in the calcium department. And calcium-fortified milk alternatives aren’t as promising as they may seem…

See, the calcium often separates from the liquid and settles at the bottom of the container – that’s not much use to anyone! What’s more, the calcium added to calcium-fortified milk is almost always rock-based. And that’s an issue, because your body wasn’t designed to consume rocks.

In reality, you’re far better off getting your calcium from leafy greens like kale or bok choy. Or better still, a plant-based calcium supplement like AlgaeCal Plus. It provides all 13 nutrients you need to support healthy bones, including 720 mg of calcium per serving – that’s more than double the amount a cup of cow’s milk provides!

And because the calcium is plant-based, you won’t have to deal with any of the side effects that rock-based calcium supplements cause (looking at you constipation).
