Dairy-Free Bone-Strengthening Foods That Might Surprise You

If you’re one of the estimated 30 million American adults with lactose intolerance — or if you avoid dairy products for other reasons — it’s important to find alternative sources of calcium to promote bone health, along with other bone-building vitamins and minerals.

Luckily, there are lots of dairy-free foods that contain the essential nutrients needed to build and maintain strong bones, including calcium, vitamin D, vitamin C, protein, magnesium, phosphorus, manganese, potassium, omega-3 fatty acids, vitamin K, and the B vitamins.

“Calcium gets all the attention, but bone health is about so much more than calcium,” says Danielle Sanders, RD, a lecturer at Yale School of Medicine Department of Internal Medicine Section of Digestive Diseases in New Haven, Connecticut. “I think oftentimes people forget that bone is a living tissue. It’s constantly being broken down and rebuilt, so it requires a constant supply of nutrients.”

An Everyday Health infographic showing 6 non-dairy foods for stronger bones: fortified plant milk, broccoli, flaxseeds, cooked collard greens, oranges, and canned sardines.

Essential Nutrients for Bone Health

Calcium is a major building block of bone health, and it's essential for healthy nerves and muscles.

If you don’t get enough in your diet, from dairy sources or nondairy sources like cooked collard greens, canned sardines, and fortified plant-based milks such as almond milk, your body will take calcium from your bones to get what it needs, Sanders says, which can thin the bones.

Adults generally need 1,000 to 1,200 milligrams (mg) of calcium daily, depending on age and sex.

In addition to calcium, it’s best to consume a combination of other nutrients for optimal bone-building benefits, says Gretchen Zimmerman, RD, CDCES, a New York City–based spokesperson for the Academy of Nutrition and Dietetics. These include:

  • Vitamin C, which plays a key role in the biosynthesis of collagen, an essential component of bone.

  • Vitamin D to help the body absorb calcium and prevent osteoporosis.

  • Protein, which helps to keep your bones dense and strong and may lower osteoporosis risk, Zimmerman says.

  • Magnesium to activate the enzymes that build new bone and help convert vitamin D into its active form, Zimmerman says, which helps your body absorb calcium.
  • Potassium to maintain the pH balance in the body, which may prevent calcium from leaching out of your bones and promote higher bone mineral density.

  • Manganese, which plays a critical role in bone regeneration, density, and overall skeletal strength, research suggests.

  • Omega-3s, which may reduce the risk of osteoporosis by promoting bone formation and preventing bone decay, Zimmerman says.

Fruits and Vegetables

Dark leafy greens contain many of the essential nutrients for bone health, especially calcium, vitamin C, and vitamin K, Zimmerman and Sanders say.

 Great bone-boosting choices include:
  • Cooked collard greens

  • Cooked spinach (Zimmerman recommends cooking or steaming spinach to remove the oxalic acid, which is a naturally occurring compound in many greens that can inhibit calcium absorption.)

  • Raw turnip greens

  • Bok choy

Cruciferous vegetables are rich sources of vitamin C and generally low in oxalic acid, which means they can help your body absorb calcium, Zimmerman says. Good choices include:

  • Broccoli

  • Brussels sprouts

  • Kale

Although not a cruciferous vegetable, red bell peppers are an excellent source of vitamin C.

Good fruit sources of vitamin C include:

  • Guava
  • Oranges
  • Grapefruit
  • Strawberries
  • Cantaloupe
  • Kiwi
  • Mango
  • Papaya
  • Pineapple
In addition to dietary fiber and a moderate amount of calcium, prunes (or dried plums) provide bone-healthy vitamins and minerals like potassium, magnesium, vitamin C, and vitamin K, Sanders says.

 They're also a rich source of boron, a bioactive compound believed to play a critical role in supporting bone metabolism, she adds.

Meat, Seafood, and Plant Proteins

How much and what type of dietary protein is ideal for promoting bone health and helping to prevent osteoporosis is still unknown.

 To keep your bones healthy, along with adequate calcium intake, aim to get the recommended 1.2–1.6 grams (g) of protein per kilogram (kg) of body weight per day, adjusting as needed based on your age and level of daily exercise.

Since protein and vitamin D are both important for bone development and retention, foods that contain both do double duty. Firm and extra-firm tofu are great sources of calcium, protein, and phosphorus, and contain vitamin D when fortified, Zimmerman says.

Similarly, sardines and salmon, whether fresh, frozen, or canned, are excellent protein choices for bone health because they contain vitamin D and omega-3s, she adds.

 The canned versions (with bones) contain the most calcium for an extra bone boost.

Additional excellent dietary sources of protein include:

  • Shellfish
  • Mackerel
  • Trout
  • Tuna
  • Quinoa
  • Eggs
  • Poultry, beef, lamb, and pork

​​Nuts, Seeds, and Legumes

Nuts and seeds are good sources of protein, vitamins, and minerals that strengthen bones, such as phosphorus and magnesium, Zimmerman and Sanders say.

Nuts like almonds and pistachios provide calcium, potassium, and magnesium, as well as protein and healthy fats. You can chop them up and add them to oatmeal, granola, yogurt, rice, and both garden and fruit salads.

Sanders recommends the following seed options for good sources of omega-3s, protein, potassium, magnesium, calcium, and B vitamins:

  • Flaxseeds

  • Chia seeds

  • Sunflower seeds

  • Sesame seeds

  • Sprouted seeds, such as pea or radish shoots, or broccoli, radish, sunflower, and arugula sprouts

Legumes and beans provide an excellent source of protein, antioxidants, and a variety of vitamins and minerals.

 Options for bone health include:
  • Chickpeas

  • Kidney beans

  • White beans

  • Lentils

  • Soybeans
