Your focus on bone health can arise for various reasons—whether due to age, activity levels, hobbies, or overall well-being. For athletes and weightlifters, maintaining bone resilience is essential for consistent performance. However, for the general population, prioritizing bone health is just as crucial, especially in preventing conditions like osteoporosis.
Understanding Osteoporosis and Bone Loss
Osteoporosis is a condition characterized by decreased bone mineral density, making bones fragile and more prone to fractures (1). While osteoporosis can become a significant issue with age, the key takeaway is that much of this process is within your control. By taking proactive steps, you can significantly reduce the risk of bone loss and maintain optimal skeletal health.
Unfortunately, many Americans are not in peak physical condition, leading to an increased risk of osteoporosis and other bone-related issues. According to the Osteoporosis Foundation, an estimated 200 million women worldwide are affected by osteoporosis. Within this number:
- 10% of women aged 60
- 20% of women aged 70
- 40% of women aged 80
- 66% of women aged 90 (2)
By understanding the key factors that impact bone health, we can implement strategies to strengthen bones naturally.
Factors That Influence Bone Health
Hormonal Changes and Bone Remodeling
In women, particularly during menopause, declining estrogen levels can accelerate bone loss, leading to osteoporosis (3). This process is influenced by the balance between osteoblasts (bone-building cells) and osteoclasts (bone-resorbing cells).
Healthy bone remodeling is a continuous and dynamic process, essential for maintaining bone size, shape, and strength (4). When osteoclast activity surpasses osteoblast activity, bone density declines, increasing the risk of fractures.
Essential Nutrients for Bone Health
Many people turn to supplements for bone support, often finding formulations containing Vitamin D3, Vitamin K2, and calcium. While these nutrients are essential, supplementation should be approached cautiously—excessive intake may have unintended consequences (5).
Instead of relying solely on supplements, a better approach is to focus on nutrient-dense whole foods and lifestyle habits that enhance nutrient bioavailability.
Whole Food Sources for Bone Support
A diet rich in diverse whole foods provides the nutrients necessary for bone strength (6, 7). Key sources include:
- Leafy greens and vegetables – Provide essential minerals and phytonutrients
- Citrus fruits – High in vitamin C, which supports collagen production
- Seafood and grass-fed meats – Excellent sources of protein, omega-3s, and essential minerals
- Dairy and poultry – Naturally high in calcium and other bone-supporting nutrients
For Vitamin K2, prioritize foods like:
- Bone marrow (available in capsules as well)
- Grass-fed beef, chicken, and eggs
- Long-fermented cheeses
Additionally, Dr. John Gildea recommends incorporating omega-3 fatty acids from high-quality sources like wild-caught fish and flaxseeds, as these help reduce inflammation and support bone integrity.
The Role of Sunlight in Bone Health
Why Sunlight Matters More Than Supplements
Research consistently shows that sunlight exposure is one of the most effective ways to enhance bone health—often outperforming vitamin D supplementation (8). When skin is exposed to sunlight, ultraviolet B (UVB) rays trigger the conversion of 7-dehydrocholesterol in the skin into pre-vitamin D3, which then transforms into active vitamin D3 (9). This process directly impacts calcium absorption and bone density (10).
Studies have found that consistent sun exposure improves bone structure and reduces the risk of fractures more effectively than vitamin D supplements (11).
Historical Insight on Sunlight and Bone Strength
Ancient observations also hint at the importance of sunlight in bone health. Greek historian Herodotus noted stark differences in bone density between Egyptian and Persian soldiers after the Battle of Pelusium:
"The Persians’ skulls were so thin that the merest touch of a pebble would pierce them, whereas the Egyptians' skulls were so tough that even a strong blow from a stone could barely break them."
He attributed this to the Egyptians shaving their heads from childhood, allowing their skulls prolonged sun exposure, while Persians wore head coverings, shielding their bones from the sun (16).
This historical perspective aligns with modern research emphasizing the critical role of sunlight in bone density and strength.
The Power of Resistance Training for Bone Density
Why Strength Training is Essential
According to Dr. John Gildea, weight-bearing exercise is a powerful tool for maintaining and improving bone density. One major reason is interleukin-6 (IL-6), a cytokine involved in inflammation and bone resorption.
As estrogen levels decline, IL-6 levels increase, leading to higher osteoclast activity and greater bone breakdown (12). However, resistance training counteracts this process by stimulating osteoblast activity and enhancing bone mineral density (BMD) (13).
Research on Strength Training and Bone Health
Studies confirm that resistance training significantly improves BMD, particularly in key areas like the hip and spine—the most vulnerable sites for osteoporosis-related fractures (14, 15). Even low-load, high-repetition exercises have been shown to mitigate bone loss and support skeletal integrity.
For postmenopausal women, incorporating strength training into a weekly routine can be one of the most effective strategies to preserve bone density and prevent fractures.
Sulforaphane: A Plant-Powered Ally for Bone Health
Sulforaphane, a natural compound found in cruciferous vegetables like broccoli, has emerged as a bone-supporting powerhouse. Research indicates that sulforaphane:
- Boosts osteoblast activity (bone-forming cells)
- Reduces osteoclast activity (bone-breaking cells)
- Shifts bone remodeling in favor of bone formation (12)
Additionally, sulforaphane has been shown to suppress bone resorption, a crucial factor in preventing osteoporosis and bone loss associated with metastatic breast cancer (13).
To incorporate sulforaphane into your routine, consider consuming broccoli sprouts or taking a bioavailable supplement like BrocElite for an optimized functional dose. Dr. John Gildea also highlights that CurcElite, a curcumin supplement, has anti-inflammatory benefits that further support bone health.
Key Takeaways: How to Strengthen Your Bones Naturally
Now that you have an overview of the factors influencing bone health, here’s what to focus on:
✅ Prioritize a whole-foods-based diet – Include high-quality animal and plant sources to reduce inflammation and supply essential nutrients.
✅ Incorporate resistance training – Weight-bearing exercises are crucial for preventing osteoporosis and improving bone density.
✅ Get consistent sunlight exposure – Studies show that natural sunlight is more effective than vitamin D supplementation for bone health.
✅ Be mindful of supplementation – Instead of relying on synthetic supplements, opt for natural plant-based solutions like BrocElite and CurcElite.
By implementing these lifestyle changes, you can fortify your bones, prevent osteoporosis, and maintain long-term skeletal strength.
