What Are Calcium Fortified Plant Milks?

Calcium fortified plant milk is non-dairy milk (aka: not from a cow or goat) that that has calcium added to it.

Calcium is typically added via calcium carbonate. Sometimes tricalcium phosphate also contributes calcium. You can find out how calcium was added by reading the ingredients list and looking for additives with the word: “calcium.”

Popular types of fortified plant milks include:

  • soy milk
  • almond milk
  • oat milk
  • cashew milk
  • coconut milk
  • rice milk
  • flax milk

Is Calcium Carbonate Vegan?

Calcium Carbonate is usually vegan because it often comes from stones, such as limestone. However, it could also come from animal byproducts, like egg shells or shellfish, making it non vegan(1).

Calcium fortified plant milks likely use vegan calcium carbonate- especially if the label has words like “vegan” or “100% plant based.” Of course, reach out to the company if you have questions.

Is the Calcium in Plant Milk Fortified with Calcium Well Absorbed?

Yes, research suggests that the calcium plant milk fortified with calcium may be absorbed similarly to cows milk (2, 3).

Plant Based Milk With the Most Calcium

In the US, an excellent source of a nutrient is defined as 20% of the daily value or more for a nutrient. While we don’t know which plant milk provides the most calcium, this list includes plant milks that can be an excellent source of calcium.

In the US, the daily value (DV) is based on 1300 milligrams of calcium per day for individuals aged 4 years old and up (4).

This list does not contain every single plant based milk (I have tried to include some of the more “well known” US brands). There may be brands that have the same, higher, or lower amounts of calcium. Since ingredients/formulations may change, please check the product recent nutrient info.

1. Kirkland Unsweetened Almond Milk

Kirkland (Costco’s brand) takes the number one spot a whopping amount of calcium! I have not seen any other plant milks that have more calcium per a 1 cup serving.

What does it taste like? The ones that I’ve tried do taste a bit watery and chalky. I prefer the flavor of other brands when it comes to almond milk.

2. Silk Original and Unsweetened Almond Milk

Not only are they fortified calcium power houses, but they also provide a few other nutrients like vitamin E and D.

3. Almond Breeze Almond Milks

Like Silk, Almond Breeze has been around for awhile! Some sources suggest it is the leading brand for sales of almond milk in the US (5)

FYI: the “Hint of Honey” flavors are not vegan diet friendly!

4. Ripple Plant-Based Milk

Ripple is pea based which contributes a notable amount of protein at about 8 grams per cup! That’s similar to cows milk.

They also have more added vitamin D than dairy milk(6, 7).

FYI: Their Half and Half options only contain about 6 milligrams of calcium per serving- so don’t count on them significantly contributing to your calcium intake.

5. Oatly Chilled Milks

Oat milk has recently become widely popular- perhaps for its smooth mouth feel that contrasts some of the more “watered down” plant milks (not to mention: some are absolutely convinced it’s the best creamer for coffee).

6. Silk Unsweetened Organic Soy Milk

Soy milk typically contains more protein than almond or oat milks.

And, this one comes with phytoestrogens that may reduce the risk of breast cancer in women- (compared to no soy intake)(8).

7. Good Karma’s Flax Milk (Refrigerated)

This milk contains flax oil, an important source of essential omega-3 fatty acid: alpha-linolenic acid(ALA). Omega 3’s help to make up cell membranes and have important roles to play for the immune system and heart health (9).

Good Karma even has a flax milk with added 8 grams of plant based protein from peas.

Why Would I Choose Calcium Fortified Plant Milks?

Here’s why someone might want to consider calcium fortified plant milks:

  • They are switching to a dairy free lifestyle and want a “milk” that provides extra nutrition.
  • The individual has lactose intolerance (difficulty digesting the sugar (lactose) in milk).
  • They have given up dairy and want something that tastes similar.
  • A vegan wants to make a recipe that calls for milk

Of course, there may be many other reasons as well!

With so many options available, you’re sure to find milk alternatives that tastes delicious and help meet calcium needs!

Are They Healthy?

Calcium fortified milk alternatives can be a wonderful addition to an overall healthy diet.

They provide readily absorbed calcium that contribute toward recommended daily allowance (RDA). For adults (19-50 years old) that’s 1000 milligrams of calcium per day(4).

Aside from calcium, plant based milks may (but not always) also provide other important nutrients such as:

To know, you’ll have to read the nutrition facts. Not all milk alternatives contain fortification.

Additionally, some plant based milks have added omega 3 fatty acids. Soy, pea, and flax milk may be decent sources of plant based protein.

It is incredibly hard to compare plant based milks to dairy milk because of how diverse vegan alternatives can be!

For example, when it comes to calories, many of the unsweetened varieties contain less per serving than cows milk.

Whole dairy milk contains more saturated fat than plant based milk in general. And generally speaking, we should limit unhealthy saturated fats.

On the flip side some plant based milks contain less protein and more sodium than dairy milk. Still, this can be easily avoided by reading the labels and choosing wisely!

With most topics in nutrition, it’s best to look at food choices in the context of your overall dietary pattern.

What is a Good Alternative to Milk For Calcium that are Dairy Free?

Calcium fortified plant milks are not a necessity. However, as we just learned, they can be a helpful and healthy option for some.

Still, if you are looking for other options that are also dairy free, here are some good alternatives to milk for calcium:

Calcium Fortified Plant Milks – In Summary

There are many ways to get calcium without the use of daily. Calcium fortified plant milks are one of several ways. There are a variety of options that may range in calcium content from about 100 – 600 milligrams of calcium per serving.

If you trouble meeting your calcium needs talk to your doctor before taking a calcium supplement.
