Omega-3 PUFAs in Musculoskeletal Health and Sports Medicine: From Molecular Pathways to Precision Nutrition Strategies
A new narrative review links omega‑3 polyunsaturated fatty acids (PUFAs) to musculoskeletal health by tracing their anti‑inflammatory and tissue‑repair pathways from the cellular level to clinical outcomes. The authors detail how omega‑3s remodel cell membranes, shift lipid mediator profiles, and inhibit NF‑κB and NLRP3 inflammasome signaling. Clinical trials show supplementation can improve bone turnover markers, ease osteoarthritis pain, and curb peri‑operative muscle loss. In sports medicine, omega‑3s boost anabolic metabolism, energy efficiency, recovery speed, and even neuroprotection, positioning them as a cornerstone of precision nutrition for athletes and patients alike.
