Nov 14, 2023 Dr. Chris McGlory, an Assistant Professor at Queen’s University, discusses the benefits of omega-3 fatty acids for muscle health. Topics include the recommended intake of omega-3s, the importance of muscle strength over size, and the impact of physical activity and resistance training. The episode also covers the effects of omega-3 on muscle fiber types and the role of omega-3 supplements in muscle growth and maintenance.

Episode notes
From UK PhD To Canadian Muscle Lab
- Chris traced his path from the UK to Canada via PhD and postdoc with leaders like Kevin Tipton and Stuart Phillips.
- Collaborations and access to mass-spec facilities shaped his focus on omega-3s and muscle turnover.
Measure Muscle Change Fast With Isotopes
- Stable isotope tracers detect muscle protein synthesis changes in hours or days rather than weeks.
- Mass spectrometry tracks labeled amino acids precisely inside muscle biopsies to measure turnover.
Membrane Incorporation Is Key
- Omega-3s (EPA/DHA) are PUFA that alter cell membrane composition and signaling.
- Their incorporation likely changes membrane order and downstream muscle processes beyond simple anti-inflammatory effects.
