OsteoStrong Fact Sheet: Omega-6 Fatty Acids for Bone and Muscle Health


Omega-6 fatty acids are essential polyunsaturated fats crucial for various bodily functions, including the health of bones and muscles. While commonly found in processed seed oils like canola and vegetable oils, these sources of Omega-6 are not considered healthy and should be avoided for optimal health benefits. Processed and fried foods which contain processed seed oils should be avoided. 

Impact on Bone Health

Bone Density and Remodelling

  • Function: Essential for bone metabolism and remodelling.
  • Balance with Omega-3s: A balanced intake with omega-3 fatty acids is key to promoting bone density and preventing excessive bone resorption.

Inflammation and Bone Health

  • Inflammatory Response: Omega-6 fatty acids can influence inflammatory processes, which are part of normal bone health maintenance.
  • Chronic Inflammation: Excess Omega-6, especially from processed oils, can lead to chronic inflammation, adversely affecting bone health.

Role in Muscle Health

Muscle Cell Function

  • Maintenance: Vital for the health of muscle cell membranes.
  • Muscle Growth and Recovery: Contributes to muscle growth and repair, especially following physical activity.

Inflammation and Muscle Adaptation

  • Exercise Response: Facilitates the body’s inflammatory response essential for muscle recovery and adaptation post-exercise.

Healthier Sources of Omega-6 Fatty Acids

  • Whole Foods Focus: Nuts (like walnuts and cashews), whole seeds (such as sunflower and pumpkin seeds), unheated avocado and olive oil, grain fed butter, cashews, and walnuts.
  • Animal Sources: Pasture-raised meats and dairy products.
  • Alternative Plant Oils: Olive oil and avocado oil, though lower in Omega-6, are healthier options.

Omega-6 and Omega-3 Ratio

  • Crucial Balance: The ratio of omega-6 to omega-3 fatty acids in the diet should be balanced for optimal health benefits. 
  • Modern Diet Trends: High consumption of processed seed oils can disrupt this balance, potentially leading to health issues.


  • Dietary Choices: Use natural, whole food sources of omega-6 fatty acids while eliminating intake of processed seed oils like canola and vegetable oils.
  • Professional Guidance: Consult with a healthcare provider or nutritionist for personalised dietary advice, especially regarding fat intake and balance.


Omega-6 fatty acids play an important role in bone and muscle health. However, the source of these fatty acids is crucial. Focusing on healthier whole foods, unprocessed sources, and maintaining a balanced ratio with omega-3 fatty acids can maximise health benefits while minimising potential negative impacts of consuming omega-6s from processed seed oils.
