The Benefits of Extra Virgin Olive Oil for Osteoporosis and Bone Health

Cold-Pressed Extra Virgin Olive Oil and Bone Health: Emerging Evidence for Osteoporosis Support

Osteoporosis, characterized by reduced bone mineral density (BMD) and increased fracture risk, affects millions worldwide, particularly postmenopausal women due to estrogen decline. While vitamins C, D, K2, and others, plus minerals like calcium, magnesium, boron, and others, as well as weight-bearing and resistance and balance training exercises make up the primary foundation for management, dietary factors are gaining attention. Observational and experimental research now points to cold-pressed extra virgin olive oil (EVOO)—a cornerstone of a healthy diet—as a potentially beneficial food for bone health. Its high content of monounsaturated fats and bioactive polyphenols appears linked to lower fracture risk and improved bone parameters in both human and animal studies.

Why Cold-Pressed Extra Virgin Olive Oil Stands Out

Extra virgin olive oil is produced solely by mechanical means (cold-pressing or similar physical processes) without heat or chemicals that degrade beneficial compounds. This preserves phenolic compounds such as hydroxytyrosol, oleuropein, and tyrosol, along with oleic acid. These polyphenols exhibit strong antioxidant and anti-inflammatory properties. Refined or lower-grade olive oils contain far fewer of these compounds, which is relevant because several studies highlight benefits specifically tied to higher EVOO intake rather than total olive oil. ¹

Key Human Evidence:

One of the strongest signals comes from the PREDIMED trial (a large Mediterranean diet intervention study). In an observational analysis nested within the trial involving 870 participants (aged 55–80 at high cardiovascular risk) from the Reus, Spain center, researchers tracked osteoporosis-related fractures over a median of 8.9 years. Participants in the highest tertile of extra-virgin olive oil consumption had a 51% lower risk of fractures (hazard ratio 0.49; 95% CI 0.29–0.81) compared with the lowest tertile, after adjustment for confounders. Total or common (non-extra-virgin) olive oil showed no such association. Treatment arm allocation itself did not affect fracture risk, underscoring the specific link with higher EVOO intake. ¹

Additional human data support related benefits. In postmenopausal women, supplementation with vitamin-enriched EVOO improved markers of bone turnover (lower undercarboxylated osteocalcin) and T-scores alongside reduced oxidative stress markers compared with plain EVOO. A polyphenol extract from olives increased serum osteocalcin (a bone formation marker) and helped stabilize lumbar spine BMD over 12 months in osteopenic postmenopausal women versus calcium alone. Other work in severely obese adults found positive effects of EVOO (alone or with diet) on bone health parameters. Mediterranean diet patterns rich in olive oil have also been associated with favorable bone formation markers. ²

These findings align with lower rates of osteoporotic fractures observed in Mediterranean populations, where EVOO is a dietary staple.

Insights from Animal and Mechanistic Studies

Preclinical research provides mechanistic support, often using ovariectomized (OVX) rats as a model of postmenopausal estrogen deficiency and bone loss. Multiple studies show that EVOO supplementation improves femoral BMD, bone biomechanical properties, histological architecture (cancellous and cortical bone), and markers of bone remodeling. It also counters hormonal shifts, oxidative stress (lower MDA and related markers), and elevated pro-inflammatory cytokines. ³

Specific polyphenols play key roles:

• Hydroxytyrosol and oleuropein stimulate calcium deposition by osteoblasts, inhibit osteoclast formation, and reduce trabecular bone loss in OVX mice.
• They act as antioxidants (scavenging free radicals and lowering H₂O₂ levels) and anti-inflammatory agents, protecting bone cells from oxidative damage that accelerates resorption.
• Tyrosol and related compounds similarly help prevent osteopenia in OVX models with or without inflammation. sciencedirect.com

Antioxidants and Micronutrients

• Vitamins: EVOO retains more natural vitamin E and vitamin K, whereas refining strips away much of these vitamin contents. ⁴
• Polyphenols: EVOO contains high levels of disease-fighting plant compounds like oleocanthal and oleuropein, which lower inflammation. Common olive oil loses most of these antioxidants during high-heat and chemical refining.

Overall, EVOO appears to tip the balance toward bone formation over resorption while mitigating the oxidative and inflammatory milieu that contributes to osteoporosis progression.

Practical Considerations

Incorporating high-quality cold-pressed EVOO is straightforward: use it as a primary fat for dressings, low- to medium-heat cooking*, or finishing dishes (typical Mediterranean intakes often range from 20–50+ mL daily in studied contexts). Look for authentic EVOO with recent harvest dates and, when possible, certified high phenolic content. It complements standard osteoporosis care, including adequate vitamin, mineral, and protein intake; exercise; and medical advice. Individual responses vary, and people with specific dietary restrictions or medical conditions should consult a natural healthcare provider, such as a Naturopathic Physician.

Limitations and Outlook

Most human data are observational or from secondary analyses rather than large dedicated randomized trials focused solely on fractures or BMD as primary endpoints. Animal doses and models do not always translate directly to humans. Still, the consistency across PREDIMED fracture data, bone marker improvements, and mechanistic studies on polyphenols is encouraging. Ongoing research into olive polyphenol extracts and functional foods continues to explore these pathways.

In summary, cold-pressed extra virgin olive oil—rich in protective polyphenols—emerges from studies as a promising dietary component for supporting bone health and potentially reducing osteoporotic fracture risk. As part of an overall healthy pattern such as a Paleo diet that includes nutritional ketosis, it offers a flavorful, accessible way to contribute to skeletal resilience. ^{4 5 6}

Dr. Robert Jay Rowen, MD, mentions the Spain study in the Rowen Report of Aug 2026, and states:

If you are using olive oil, but not extra virgin, please do a self-check of your oil vs. extra virgin. Note the color difference and taste differences. EVOO is darker green, not the pale yellow of common olive oil, similar to the color of seed oils. EVOO should taste more bitter, as the high polyphenols therein happen to be bitter-tasting.

He goes on to say,

Common olive oil is largely devoid of the precious medicinal, anti-ageing, anti-inflammatory polyphenols, while retaining largely the same fat profile. Common olive oil is no better than common seed oils. I believe that the results of the study were due to these fabulous medicinal properties of the constituents of EVOO. Why take drugs when food will do the same or better, and at no risk?
