Omega-3 fatty acids, primarily found in fish oil and certain plant sources, have been investigated for their potential role in bone health, including the healing of broken bones. There is emerging scientific evidence—largely from animal studies and a smaller number of human observational studies—suggesting that omega-3 fatty acids may positively influence bone healing. These effects are thought to be mediated through the anti-inflammatory properties of omega-3s, which can reduce the production of pro-inflammatory cytokines and support the activity of osteoblasts (cells responsible for bone formation) while inhibiting osteoclasts (cells involved in bone resorption).

Some animal studies have shown that supplementation with omega-3 fatty acids can increase bone mineral density and improve bone strength, which are relevant to both fracture healing and overall bone health. For example, rodent models have demonstrated enhanced fracture healing and improved bone quality with omega-3 supplementation. Human data are more limited and less conclusive. A few observational studies have found associations between higher omega-3 intake and better bone density or reduced fracture risk, but robust clinical trials specifically assessing fracture healing are lacking.

Overall, while there is plausible biological rationale and some preliminary evidence supporting a beneficial role for omega-3 fatty acids in bone healing, definitive evidence in humans is still limited. Therefore, while omega-3 supplementation may support general bone health, it should not be considered a primary treatment for broken bones until more high-quality clinical trials are available.
