Calcium Sources That Don't Require a Cow

Soy, Rice, and Nut Milk

While milk and other dairy products are well known for their calcium content, fortified milk alternatives can also help you get enough of this important nutrient in your diet. The U.S. Department of Agriculture (USDA) recommends that adults get three cups of low-fat dairy products or fortified soy-based alternatives in their diet every day.

Cow's milk alternatives are fortified with both calcium and vitamin D, so they provide a substantial amount of your daily calcium intake. These milk alternatives come in a variety of flavors including, plain, vanilla, and chocolate, plus there are similar 'coffee creamers' made with these products as well.

Calcium-Fortified Orange Juice

Orange juice is already an excellent source of vitamin C and potassium and adding calcium makes it even more beneficial. Depending on the brand, an 8-ounce serving of calcium-fortified orange juice can supply you with up to 35% of your daily calcium need. Make sure the label states the juice has added calcium (bonus points if it also has vitamin D).

Tofu

Tofu is made from soy. It's often used in place of meat in stir fry or curry dishes. Tofu is an excellent source of calcium as long as it's prepared with calcium sulfate—half a cup can provide about half of your daily calcium requirement. Be sure to look at the label for tofu processed with calcium—it's also an excellent source of protein and other essential minerals.

Kale

Kale is one of those superfoods that seems to be high in just about every nutrient you can think of except for vitamin B-12. A cup of raw kale is enough to satisfy about 10% of your daily calcium requirement. It's also low in calories—about 7 or so per 1-cup serving.

Bok Choi

All the dark green leafy vegetables are high in calcium and bok choi, (also known as Chinese cabbage, or pak choi) is no exception. One cup of shredded cooked bok choi has about 150 milligrams of calcium—about 15% of your daily requirement.

Almonds

Almonds make a healthy snack or a nutritious addition to a salad or side dish. One ounce of almonds (about 24 of them) has just under 100 milligrams of calcium. They're also rich in magnesium, manganese, and vitamin E, plus they contain plenty of healthy fats.

Broccoli

Broccoli is another terrific plant source of calcium. One cup of chopped broccoli will provide about 5% of your daily need, plus it's rich in most other vitamins and minerals, plus fiber and antioxidants. Definitely worth a second helping.

Collard Greens

Collard greens are very high in calcium. In fact, one cup of collard greens supplies about one-fourth of your daily requirement. Collard greens are also high in several minerals, B vitamins, vitamin A and fiber.

Rhubarb

Rhubarb is a tangy source of calcium. It's also high in vitamin C, potassium and fiber. It's probably too tart to eat without a bit of sugar, but one cup of rhubarb pieces has about 10% of your daily calcium need.

Spinach

Spinach is loaded with nutrients including iron, calcium, vitamin C and fiber, and most other vitamins and minerals. One cup of cooked spinach has about 25% of your daily calcium requirement. Raw spinach is good too, but cooking the spinach really concentrates the nutrients since you'll consume more of the vegetable.

Navy Beans

Navy beans are an excellent source of non-dairy calcium. One cup of cooked navy beans has 125 milligrams for close to 15% of your daily requirement. They're also high in fiber and manganese. 

Swiss Chard

Swiss chard is high in calcium. One cup of Swiss chard will cover 10 percent of your daily calcium requirement. Chard is also high in fiber, vitamins A and C, and potassium and several minerals.

Stewed Tomatoes

Stewed tomatoes are an excellent source of calcium. Fresh tomatoes have some calcium as well, but the cooking process concentrates the amount of tomatoes you consume in a serving, which supplies more minerals. One cup of stewed tomatoes contains nearly 10% of your daily calcium requirement. They're also high in potassium and iron, plus they're rich in vitamins A and C.

Pinto Beans

Legumes, in general, are good calcium sources, and one cup of pinto beans supplies you with about 8% of your daily calcium requirement. They're also high in manganese and fiber, plus a little vitamin C. Black beans and kidney beans are also good sources—one cup of either bean has about 5% of a day's calcium need.

Brazil Nuts

Brazil nuts are best known as an important source of selenium, but they're also an excellent source of calcium. Six Brazil nuts have about 50 milligrams and supply about 5% of your daily need. They're also high in magnesium and healthy fats.
