These 12 healthy plant-based foods are high in calcium. Include these vegan sources of calcium in your diet for strong bones!

From a young age, you’ve been taught that calcium is synonymous with dairy. And while that’s true, you can still get calcium in a plant-based diet. 

Although calcium is most abundant in milk, yogurt and cheese, you can get calcium from plant sources too. Make sure you’re eating these foods regularly to ensure you’re taking in enough of this bone-building mineral on a plant-based diet.

What is calcium?

Calcium is the most abundant mineral in the body, making up a large portion of bones, nails and teeth. It plays a significant role in muscle contraction, brain signaling and blood flow and clotting. 

Most notably, calcium (and Vitamin D) is found in the bones. As you age, the bones deteriorate, making calcium intake essential for skeletal health. Approximately 10 million Americans are diagnosed with osteoporosis, while another 44 million have low bone mineral density. 

The good news is that taking in enough calcium throughout your lifetime can prevent an osteoporosis diagnosis. 

The recommended daily intake for calcium is between 1,000 and 1,200 milligrams per day for adults, depending on age.

Men and women up to the age of 50 should eat 1,000 milligrams of calcium per day. After 50, the recommendation increases to 1200 milligrams per day for both men and women. 


Is plant calcium as good as regular calcium?

The most absorbable form of calcium comes from dairy and fortified foods, such as plant-milks, OJ and cereal. About 30% of the calcium from these foods is absorbed into the body.

Some plant-based foods contain compounds called oxalic acid and phytic acid, which decrease calcium absorption to about 5%. These compounds are in leafy greens, like spinach and collard greens.

However, the other plant-based forms of calcium on this list are well-absorbed by the body. To ensure that your body absorbs enough calcium to protect the bones, teeth and hair, eat a variety of plant-based calcium sources.

What are the symptoms of a calcium deficiency? 

Here are some of the most common symptoms that accompany low calcium levels (or hypocalcemia): 

  • Numbness or tingling in the fingers 
  • Muscle cramps 
  • Muscle Weakness 
  • Abnormal heart rate 
  • Loss in appetite 


What is the best source of plant-based calcium?

It’s hard to choose one food as the “best” source of plant-based calcium, but this one tops the list.

Soy milk, 1 cup = 240 mg (24% daily value (DV))

Although the amount of calcium in soymilk varies from brand to brand, most shelf-stable soy milk are an excellent source of calcium. Soy naturally contains calcium, and soy milk is a protein-rich plant-milk that is concentrated in the bone building nutrient.

Soy milk is also usually fortified with Vitamin D for bone health. Buy the unsweetened variety for smoothies, muffins, pancakes and more.

Incorporate plenty of these plant-based calcium sources into your diet daily:

Other sources of vegan calcium

Besides soy milk, there are plenty of other good sources of plant-based calcium. Here are foods that top the list.

White Beans, 1 cup = 131 mg (13% DV)

White beans come in various forms– navy beans, northern beans, cannellini beans and lima beans. They make a great addition to soups, salads and chili, or they can serve as the base for creamy dips. 

Edamame, 1 cup = 98 mg (10% DV)

This sushi night appetizer tastes good and’s full of bone-building nutrients, like calcium and protein. I love to keep a pack of these in my freezer at all times and eat them for a satisfying snack or dinner side dish. Add shelled edamame to a vegan sushi bowl for a hearty and filling protein. 

Tofu, 3 ounces = 100 mg (10% DV)

If you are a vegan, you can still get plenty of calcium from soy products, like tofu. Three ounces of tofu is a good source of calcium. And good news– most people eat more than 3 ounces in one sitting. 

Not to mention that tofu is easy to cook and takes on the flavor of basically any marinade. Spice up your meals by trying these tofu recipes:

Chia seeds, ¼ cup = 107 (10% DV)

This tiny seed has large nutritional benefits, including healthy omega-3 fats and bone-boosting calcium. You can add these seeds to any breakfast food, like oatmeal, chia seed pudding and smoothies or even use them as an egg replacement in these baked oatmeal cups. 

Collard Greens , 1 cup = 84 mg (8% DV)

Collard greens are a dark leafy vegetable that are often overlooked, but they have plenty of calcium. I love using collard greens as a wrap replacement since it’s a thicker, tougher green leaf that won’t rip apart when you roll it up!

Kale, 2 cups = 120 mg (12% DV) 

Whether you love or hate kale, it’s worth the hype. This leafy green has plenty of plant-based calcium, Vitamin C and Vitamin K. It’s also rich in inflammation-fighting antioxidants. If you’re a kale lover, use it as the base for a salad. If you still need some warming up to it, pair it with creamy ricotta in this pasta dish. 

Butternut Squash, 1 cup = 67 mg (7% DV)

This gorgeous winter vegetable is not just high in Vitamin A—it’s also packed with potassium and calcium. A cup cooked has a little less than 10% of your daily calcium needs. Plus, it’s sweet, versatile and easy to cook. Roast it, mash it or throw it in a 4-ingredient soup. Or use it as the base for taco night!

Almonds, 1 ounce = 76 mg (8% DV)

Just twenty-three almonds (or 1-ounce) packs a nutritional punch, with plenty of healthy fats, protein and calcium. Eat the unsalted roasted variety or take it up a notch with this simple Cinnamon Roasted Almonds treat. 

Figs, ½ cup dried figs = 125 mg (13% DV)

These gorgeous and juicy dried fruit have fiber and calcium, making them a great addition to everything from oatmeal to salads. Eat dried figs in this yummy mini chocolate olive oil fig cake or drizzle fresh figs with honey and sea salt and eat them whole.

Tahini, 2 tablespoons = 120 mg (12% DV) 

Otherwise known as ground sesame seeds, tahini is a thick paste that is one of the main ingredients in hummus. But it’s also become a popular allergen-friendly substitute for nut butter. Try tahini in these delicious pre-workout Tahini Maple Oat Balls.

Fortified Orange Juice, ½ cup (4 ounces) = 150 mg (15% DV)

Some orange juices are fortified with calcium. This means they don’t naturally contain calcium, but it’s added to the juice. It’s added in a form called calcium citrate malate (CCM), and research has found that this form of calcium is readily absorbed and contributes to overall bone health. In other words, opt for the calcium fortified orange juice, if you follow a plant-based diet. 

How do I maximize calcium absorption? 

Although not as often recognized as calcium, Vitamin D plays a large role in bone health. Not only does it help the body absorb calcium, it also protects you from developing osteoporosis, a disease that thins and weakens the bones and makes them more likely to break.

Vitamin D is also involved in the immune system, working to fight off invading bacteria and viruses. Lastly, adequate vitamin D intake has been associated with reduced inflammation in the body.

Vitamin D is naturally present in only a few foods, such as fatty fish, eggs, beef and mushrooms. Obviously, this poses a problem for vegetarians and vegans. Vitamin D is also produced when ultraviolet (UV) rays from sunlight hit the skin and trigger vitamin D synthesis within the body. Yet, Vitamin D absorption from sunlight varies widely based on skin tone, sun exposure and climate. 

Ask your doctor to check your Vitamin D levels to see if you need a supplement.

Other nutrients you need on a plant-based diet

There’s a few nutrients that are a bit trickier to get on a plant-based diet– protein, iron and Vitamin B12. That doesn’t mean you can’t get them or will be deficient. It just means that you need to plan ahead to make sure you’re eating a well-balanced diet with the nutrients you need.
