OsteoStrong Fact Sheet: Omega-3 Fatty Acids for Bone and Muscle Health


Omega-3 fatty acids, commonly found in fish oil and various plant sources, are essential fats that play a crucial role in overall health, including the health of bones and muscles.

Omega-3 Fatty Acids and Bone Health

Bone Density

  • Support: Omega-3s contribute to the maintenance of bone density.
  • Risk Reduction: May reduce the risk of osteoporosis and bone fractures.

Calcium Balance

  • Enhancement: Assist in the body’s calcium balance, which is vital for bone health.
  • Absorption: Can improve calcium absorption and reduce urinary calcium loss.

Inflammation Reduction

  • Bone Protection: Anti-inflammatory properties of omega-3s help protect against bone loss associated with chronic inflammation.

Omega-3 Fatty Acids and Muscle Health

Muscle Mass

  • Preservation: Omega-3s aid in preserving muscle mass, particularly important in aging individuals.
  • Strength Improvement: Have been shown to improve muscle strength and functionality.

Muscle Recovery

  • Post-Exercise: Assist in reducing muscle soreness and accelerating recovery after exercise.
  • Anti-inflammatory Benefits: The anti-inflammatory effects contribute to quicker muscle recovery.

Dietary Sources of Omega-3 Fatty Acids

  • Fish: High levels in fatty fish like salmon, mackerel, and sardines.
  • Plant-Based: Flaxseeds, chia seeds, walnuts, and hemp seeds are excellent plant sources.
  • Supplements: Fish oil or algae-based supplements are available for those who do not consume enough through their diet.

Considerations and Recommendations

  • Balance with Omega-6 Fats: A healthy balance between omega-3 and omega-6 fatty acids is crucial for optimal health benefits.
  • Sources: Farmed fish, microplastics and heavy metals are a concern. Wild caught fish may be better in moderation. 
  • Dosage: The recommended intake can vary depending on health status, age, and dietary needs.


Omega-3 fatty acids are vital for maintaining bone density and muscle health. They offer anti-inflammatory benefits and support calcium metabolism, contributing to stronger bones and muscles. Incorporating omega-3-rich foods into the diet or considering supplementation can be beneficial for overall musculoskeletal health, especially in populations at risk of bone density loss or muscle wasting. Recent research about the source of Omega-3’s warrants close investigation. As always, consulting with a healthcare professional is recommended to determine appropriate intake levels.
