Include these key nutrients for stronger bones

Hello,

I’ve always been especially conscious of my bone health because osteoporosis runs in my family. Knowing that my risk is higher has motivated me to pay attention not only to calcium, but to the entire team of nutrients that keep bones strong and resilient. Over the years—both personally and in my work with clients—I’ve seen how powerful food and nutrition can be in protecting bone health and reducing fracture risk.

Bones may seem solid and unchanging, but they’re actually living tissue. They constantly break down and rebuild themselves, and the nutrients you eat determine how well that process works. Here are the key players I focus on when it comes to building and protecting bone strength.

Calcium

Calcium is the primary mineral in bones, giving them strength and structure. Without enough calcium in your diet, your body will pull it from your bones to keep blood levels steady—which over time can weaken them.

Beyond dairy, calcium is found in greens (kale, Bok choy, broccoli), fortified plant milks, tofu made with calcium sulfate, almonds, and canned fish with bones such as salmon or sardines.

If you opt for a supplement calcium citrate is better absorbed than carbonate.

Tasty tip: I like to add a sprinkle of parmesan cheese or feta to roasted vegetables. It boosts flavor while sneaking in some extra calcium.

Vitamin D

Vitamin D is essential for absorbing calcium from food. Think of it as the key that unlocks calcium’s benefits. Without it, even a calcium-rich diet won’t fully protect bones.

Sunlight is our best natural source but depending on where you live and how much time you spend outdoors, it may not be enough. Food sources include fatty fish (salmon, sardines, mackerel), fortified dairy and plant milks, and eggs. Supplements are often recommended if blood levels are low.

Personal strategy: I try to include salmon once or twice a week. It’s satisfying, supports bone health, and provides heart-healthy omega-3s.

Protein

Protein makes up about half of bone tissue by volume. Adequate protein helps maintain bone density and muscle mass, which together reduce fracture risk.

Lean meats, poultry, fish, eggs, beans, lentils, nuts, and Greek yogurt are excellent options. For plant-based eaters, pairing legumes with whole grains makes a complete protein.

Tip I share with clients: A simple snack of Greek yogurt with berries and walnuts delivers protein, calcium, and healthy fats all in one bowl.

Vitamin K

Vitamin K plays a fascinating role in bone health. It helps proteins bind calcium into the bone matrix, improving bone mineralization. There are two forms worth noting:

• Vitamin K1 is found in leafy greens like spinach, kale, and broccoli.
• Vitamin K2 is found in animal foods (cheese, egg yolks, chicken, beef) and fermented foods like natto (fermented soybeans). K2 appears especially important for directing calcium into bones and away from arteries, supporting both skeletal and cardiovascular health.

My practice: I aim for greens daily (for K1) and include eggs or cheese a few times a week for K2. I take a K2 supplement to ensure that I get enough.

Magnesium

Magnesium helps regulate calcium levels and activates vitamin D, so it indirectly supports bone strength. Many people don’t get enough of it.

You’ll find magnesium in nuts, seeds, beans, whole grains, and leafy greens. If you opt for a supplement, I advise magnesium glycinate which is well absorbed and can also help your muscles relax.

Easy add-in: A handful of pumpkin seeds tossed on a salad gives both crunch and a magnesium boost.

Other Nutrients That Help

• Phosphorus: A major bone mineral, found in poultry, fish, beans, nuts, and dairy.
• Potassium: Helps neutralize acids that cause calcium loss, found in bananas, potatoes, and beans.

Supporting your bones isn’t about chasing one magic nutrient—it’s about balance. A plate that’s colorful with vegetables, includes a source of protein, and provides healthy fats will naturally deliver many of the vitamins and minerals bones need.

I like to think of my bones as a “savings account.” Every time I have a calcium-rich meal, get some sunlight, or snack on nuts and seeds, I’m making a deposit. With a family history of osteoporosis, I feel empowered knowing that daily choices—small as they may seem—can strengthen my “bone bank” and help me stay active and independent as I age.

Bone health is not just about avoiding osteoporosis; it’s about preserving freedom and vitality for years to come. By paying attention to calcium, vitamin D, protein, magnesium, vitamin K1 and K2, and other supporting nutrients, you can give your bones the tools they need to stay strong for life.

Have a healthy week.
