Maintaining strong and healthy bones is essential for overall well-being, particularly as we age. Bone density naturally declines over time, increasing the risk of osteoporosis, which weakens bones and makes fractures more likely. Millions worldwide struggle with poor bone health, but the good news is that the right nutrition can significantly improve it.
Your diet plays a crucial role in bone strength. By incorporating the best foods for bone health—rich in calcium, magnesium, vitamin D, and vitamin K—you can improve bone mineral density, support skeletal strength, and naturally lower your risk of osteoporosis.
A strong skeletal system depends on various nutrients, not just calcium. Magnesium, Vitamin K, and Vitamin D also play critical roles in maintaining bone density, preventing fractures, and supporting overall bone health. While many people assume that dairy and animal products are essential for strong bones, numerous plant-based sources provide many nutrients for optimal bone health, so a combination is ideal.
I often see clients with osteopenia or osteoporosis due to poor absorption of the foods suggested below, so gut health is vital for strong bones. If you suspect you have poor absorption, add a digestive enzyme vegan capsule before meals, such as our Digestive Support Capsules.
10 Nutrient-Rich Foods for Healthier Bones
Here are the top 10 foods for optimal bone health:
1. Leafy Green Vegetables
Dark leafy greens are rich in calcium, magnesium, and vitamin K, critical for bone formation and density. Include dark leafy greens daily, such as kale, collard, bok choy and mustard greens). Broccoli and Brussels sprouts are also excellent calcium and magnesium sources, essential trace elements for strong bones. Chlorella and Spirulina is also high in Vitamin D so add these super greens into your diet daily and you can choose a powder or capsule form.
2. Fatty Fish (Salmon, Sardines, Mackerel)
Fatty fish provide vitamin D and omega-3 fatty acids, which enhance calcium absorption and reduce inflammation that may weaken bones. If you dislike eating fish, supplement it with a fish oil capsule.
3. Nuts and Seeds
Nuts and seeds are packed with magnesium and phosphorus, which support bone structure and mineralisation. Avoid peanuts and cashews, which can cause fungus and inflammation. I love walnuts, almonds, Brazilian nuts, pecans, chia, and flaxseeds. See the recipe for my Gut-Healing Chia pudding here.
4. Mushrooms
Mushrooms are a good natural source of vitamin D, which helps regulate calcium levels and improve bone strength. In particular, shiitake, maitake and portobello – especially sun-dried - are high in vitamin D. If you find it difficult to eat these exotic mushrooms each week, you can fast-track like I do with a vegan mushroom supplement.
5. Legumes
Legumes offer calcium, magnesium, and plant-based protein, essential for maintaining bone density. Lentils, chickpeas and black beans are good sources of prebiotic fibre.
6. Vitamin K Veggies
Vitamin K activates Bone Proteins and Supports mineralisation). The best sources of vitamin K include kale, spinach, collard greens, broccoli, asparagus, Brussels sprouts, green peas, cucumber, leeks and spring onions.
7. Fermented Foods
Whole grains are excellent sources of magnesium, which helps convert vitamin D into its active form for optimal calcium absorption. Opt for gluten-free options such as quinoa or black rice. Fermented foods such as natto, kimchi and sauerkraut are excellent sources of vitamin K & wonderful to support a healthy gut microbiome. Adding a targeted probiotic like our Gut Repair capsules will also help you boost your gut health.
8. Tofu and Tempeh
These soy-based foods contain high levels of calcium and isoflavones, plant compounds that promote bone health and prevent mineral loss. Just make sure you buy NON-GMO.
9. Fruits
Berries provide vitamin C, which supports bone collagen formation and is rich in antioxidants and flavonoids to boost overall health. Prunes also contain boron and vitamin K, which enhance bone metabolism. Avocado & Figs are also good sources of magnesium.
10. Organic Kefir
Kefir is a fermented milk drink similar to a thin yoghurt or ayran made from kefir grains, a specific type of mesophilic symbiotic culture & packed full of good bacteria. Kefir is an excellent source of calcium, the most essential mineral for bone strength. Kefir also provides probiotics, which aid in calcium absorption. Choose organic to avoid added hormones, pesticides and antibiotics.
Additional Health Hacks for Strong Bones
-
Exercise Regularly: Weight-bearing and resistance exercises promote bone strength.
-
Get Enough Sunlight: Sun exposure (20-30 minutes a day) helps your body synthesise vitamin D.
-
Limit Processed Foods: Excessive salt, sugar, and caffeine can deplete calcium levels.
-
Maintain a Balanced Diet: Ensure adequate intake of bone-supporting nutrients like vitamin D, K2, magnesium, and phosphorus.
By incorporating these bone-boosting foods into your diet and following a healthy lifestyle, you can strengthen your bones and lower your risk of osteoporosis. If you're not sure about your bone health and are over 45, I suggest a DEXA scan for many of my clients who all of a sudden have a fracture with no idea that they had poor bone health.

Frequently Asked Questions (FAQs)
1. What are the best foods for bone health?
The best foods for bone health include leafy green vegetables (rich in calcium and vitamin K), fatty fish (for vitamin D and omega-3s), nuts and seeds (high in magnesium), and fermented foods (which support gut health for better nutrient absorption). Incorporating these into your diet can help strengthen bones and prevent osteoporosis.
2. How does vitamin D help bone strength?
Vitamin D is essential for calcium absorption, ensuring that your body effectively uses the calcium you consume. Without enough vitamin D, bones can become weak and brittle. You can get vitamin D from fatty fish, mushrooms, fortified foods, and 20–30 minutes of sun exposure.
3. Can gut health affect bone density?
Yes, gut health plays a vital role in bone density. If your gut isn't absorbing nutrients properly, your bones won't get the calcium, magnesium, and vitamin D they need. Taking digestive enzymes or probiotics—like Rejuv's Gut Repair Capsules—can support better nutrient absorption and stronger bones.
4. What is the best natural way to prevent osteoporosis?
To naturally prevent osteoporosis, focus on a nutrient-rich diet, including calcium, vitamin D, magnesium, and vitamin K. Regular weight-bearing exercise, sun exposure, and limiting processed foods can also help maintain strong bones. If you're over 45, consider a DEXA scan to assess your bone health.
5. Can you get enough calcium from a plant-based diet?
Yes! While dairy is a common source of calcium, many plant-based foods—like kale, bok choy, almonds, tofu, and chia seeds—are also excellent sources. Combining these with vitamin D-rich foods and a healthy gut will help maximise calcium absorption.
