Quick answer: Bone is living tissue that constantly remodels. Calcium and vitamin D matter, but strong bones also depend on vitamin K2, magnesium, protein, collagen, trace minerals, healthy hormones and, most of all, weight-bearing and resistance exercise. Building and protecting bone is possible at any age.
Key nutrients beyond calcium and vitamin D
- Vitamin K2: helps bind calcium into bone (see who should consider vitamin K2)
- Magnesium: much of the body’s magnesium is stored in bone, and it helps activate vitamin D
- Protein and collagen peptides: collagen forms the flexible framework of bone
- Boron, zinc, copper, manganese and silica: cofactors for building bone
- Omega-3s: help calm inflammation that drives bone breakdown
- Strontium: studied for bone density; it can distort DEXA readings and is not appropriate for everyone
Food first: leafy greens, dairy or fortified alternatives, sardines with bones, beans, nuts and seeds. If you work with me, the products I use are in my Fullscript dispensary. See also who should consider vitamin D3.
Habits that build bone
- Weight-bearing and resistance exercise, the strongest signal for bone building
- Enough protein spread across the day
- Balance training to prevent falls
- Limiting soda, excess alcohol and smoking
- Safe sun exposure for vitamin D
Bone and healthy aging
Bone is also an endocrine organ: it releases osteocalcin, a hormone involved in blood sugar and muscle function. With age, the stem cells that build new bone become less active and inflammation favors breakdown, which is why bone loss accelerates later in life. Strength training and good nutrition help counter that. Related: osteoporosis prevention and strength training for longevity.
Safety
According to the NIH Office of Dietary Supplements, adults need 1,000 to 1,200 mg of calcium a day from all sources, and more is not better: too much from supplements may raise the risk of kidney stones. If you have kidney disease, take blood thinners or have a history of kidney stones, talk with your provider before taking bone supplements.
When to see a naturopathic doctor
- You have osteopenia or osteoporosis, or a family history
- You are approaching or past menopause
- You have taken steroids, acid blockers or other medications that affect bone
- You want a bone plan beyond calcium
See a medical provider promptly for a fracture from a minor fall, sudden back pain with height loss, or new bone pain.
Want a bone-strength plan that goes beyond calcium?
A free 15-minute consultation with Dr. Kneessi. No cost, no obligation. In-office in Odenton, MD or by telehealth.
Frequently asked questions
Is calcium enough for strong bones?
No. Bone also needs vitamin D, vitamin K2, magnesium, protein, trace minerals and exercise.
What exercise is best for bones?
Weight-bearing exercise such as walking, and resistance training such as lifting weights, give bones the strongest signal to build.
Can you rebuild bone after 50?
Bone remodels throughout life. Exercise, nutrition and, when needed, medication can help maintain or improve bone density.
Should I take strontium?
It has been studied for bone density but affects DEXA scan readings and is not right for everyone. Discuss it with your provider.
