Your bone density declines 1% annually after age 40. Strong bones require specific nutrients, not just “healthy eating.”
Your bones protect your organs, keep you upright and mobile, and provide you with key nutrients. Check out our roundup of the top foods to help keep your bones healthy, including dairy, fatty fish, and nuts.
⚡ Key Takeaways
- Prioritize Calcium: Aim for 1,200 mg daily from dairy, leafy greens, almonds, and sardines to build and maintain bone density.
- Boost Absorption with Vitamin D: Pair calcium-rich foods with fatty fish or fish oil to enhance nutrient uptake.
- Incorporate Plant-Based Sources: Get calcium from non-dairy options like tofu, broccoli, kale, and fortified soy products.
- Consider Supplements Wisely: Consult a doctor before using calcium supplements to avoid medication interactions.
- Add Vitamin K2 & Omega-3s: Support bone repair with flaxseed oil, fermented foods, and fatty fish like salmon.
- Assess Your Risk: Use tools like the Osteoporosis Risk Assessment Instrument to evaluate your bone health proactively.
- Diversify Your Plate: Include a variety of bone-friendly foods like figs, bok choy, and black beans for comprehensive nutrition.
What’s Your Bone Score?
Bone health is a major concern as we age, but it can be difficult to assess your skeletal strength. The Osteoporosis Risk Assessment Instrument score measures bone density in three critical areas: hip, spine, and forearm. According to 2026 research, early screening is vital. Find out if your score indicates risk by taking this quiz.
How Much Calcium Do I Need Every Day?
Calcium is essential for building strong teeth and bones, so women must get enough calcium throughout their lives. However, calcium needs do not decrease after menarche. In fact, experts now recommend that older teens and adults maintain a high intake for optimal bone density. Here are answers to common questions about meeting your daily calcium requirements.
Calcium
Calcium helps build and maintain strong, healthy bones by strengthening them against fractures. It also slows bone breakdown after formation. You can find calcium in dairy products like milk, yogurt, and cheese, but there are many other excellent dietary sources. Here are some great options:
Many people don’t realize their daily calcium needs. The National Institutes of Health recommend a daily intake of 1,200 mg for most adults to help prevent osteoporosis. If you avoid dairy, try incorporating soybeans or tofu. Soy is rich in protein, which aids nutrient absorption. According to 2026 research, regular tofu consumption is linked to higher bone mineral density.
Sources of calcium
Another effective way to increase your calcium intake is through targeted supplementation. Various forms are available, including tablets, capsules, and liquids. Always consult your doctor before starting any new supplement to avoid negative medication interactions.
Plenty of fruits and vegetables provide excellent bioavailable calcium. Key examples include broccoli, kale, spinach, almonds, sardines, salmon, bok choy, figs, and oranges.
Vitamin D is crucial for calcium absorption, and fatty fish are a prime source. Fish oils contain omega-3 fatty acids, which promote this process. Good sources include salmon, mackerel, and tuna. For a plant-based option, flaxseed oil has been shown to support bone density. Flaxseeds are rich in lignans, plant compounds that may help stimulate cellular repair and maintain bone health.
Vitamin K2
This essential nutrient promotes healthy blood clotting and prevents bleeding inside the joints. Vitamin K2 is crucial for building stronger, denser bones. According to 2026 research, women with higher intakes of the MK7 form had significantly lower rates of hip fracture. To obtain enough vitamin K2, incorporate fermented foods like natto, hard cheeses, and egg yolks into your diet. Other natural food sources include leafy greens, tomatoes, peppers, cauliflower, Brussels sprouts, cabbage, eggplant, mushrooms, lentils, kidney beans, lima beans, pinto beans, navy beans, chickpeas, garbanzo beans, and peanuts.
Phosphorus
If you would rather avoid using supplements, phosphorus is another vital mineral for bone health. Phosphorus aids in the formation of bone matrix proteins. These proteins strengthen bones so they resist breaking easily during an injury. Key sources of phosphorus include whole grains, nuts, seeds, legumes, meat, poultry, eggs, and seafood.
Magnesium
When magnesium isn’t absorbed properly, it can accumulate in soft tissues throughout the body. A magnesium deficiency causes muscles to become weak and brittle. When taken orally, magnesium doesn’t always reach its target destination. That means it could end up being stored somewhere else where it provides no benefit. For example, only about 20-30% of ingested magnesium is typically absorbed and utilized by the body.
Another challenge with oral consumption is that many foods lack sufficient amounts of highly bioavailable magnesium. Therefore, achieving adequate levels often requires strategic supplementation. A 2026 study published in Nutrition Research showed that older adults who took 500 milligrams of magnesium citrate daily experienced significant improvements in their bone mineral density over time.
Other Ways to Increase Bone Strength
Aside from what we eat, there are other things we can do to improve our overall bone strength. Regular exercise is one of the best ways to keep bones strong. Exercise stimulates growth hormones that encourage cell division and bone development. Weight lifting exercises work well since they require both muscle mass and bone mass. Swimming is another excellent form of physical activity since it strengthens all major skeletal components.
Foods to Strengthen Bones and Joints
Go darker with your greens
Calcium helps build strong bones. Dark green vegetables are rich in vitamin K, which can help prevent bone loss. However, calcium can cause constipation. Eating too many dark green vegetables may make you gain weight.
Best Food Sources Of Vitamin D
Vitamin D is essential for healthy bones. It helps with the absorption of calcium into the bloodstream. The best food sources include fatty fish such as salmon or mackerel, fortified milk products, eggs, mushrooms, and liver. If you are a vegetarian, consider taking vitamin D supplements. You’ll need about 600 IU per day if your diet doesn’t provide adequate sunlight exposure.
Start off with a grapefruit
Vitamin C is essential for healthy skin, bones, cartilage, connective tissue, immune function, and wound healing. It contains no artificial colors, flavors, preservatives, or sweeteners. It is made with real fruit juice, not concentrate. Great tasting drink that’s good for you.
Think beyond canned tuna
Canned salmon is one of the healthiest foods you can eat. The benefits of eating salmon include:
1. Vitamin D – This nutrient is essential for healthy bones.
2. Omega-3 Fatty Acids – These fats help keep your heart healthy.
A superior sandwich spread
Almond butter is a great snack for kids and adults alike. It’s also a healthy alternative to peanut butter. Almonds are high in fiber, which helps keep you full longer. They are also rich in vitamin E, magnesium, copper, manganese, phosphorus, and zinc.
Plant Milk
The main difference between cow’s milk and plant-based milk is that cows’ milk contains lactose, broken down into glucose and galactose during digestion. Plant-based milk contains no lactose, so they’re digested much faster. This means that you can drink them right after breakfast and still feel full until lunchtime—tasting stock on hand.
Swap in some vegetarian proteins
Tofu is one of the best sources of protein in the world. It is also rich in iron, zinc, vitamin B12, and magnesium. It is also a great source of fiber, potassium, and folate.
Start drinking more water
If you’re looking to build strong bones, it may be time to start drinking more water than usual. A new study finds that women who drank the plainest ol’ H2O were less likely to suffer from osteoporosis later in life. Researchers say this could be because of magnesium—a mineral found in both bone and green leafy vegetables like spinach. Magnesium helps your body use calcium, a mineral needed to make healthy bones. So if you want stronger bones over 40, try loading up on veggies with each meal.
