The Omega-3 Supplementation Guide
A blueprint for choosing the right fish oil supplement — filled with specific recommendations, guidelines for interpreting testing data, and dosage protocols.
Omega-3 fatty acids, particularly EPA and DHA, are being studied for their potential effects on human skeletal muscle and mitochondrial function. Researchers believe incorporating these fatty acids into mitochondrial membranes might alter ADP handling and oxygen utilization, potentially affecting muscle protein synthesis and energy production. Additionally, some evidence suggests that omega-3s can increase metabolic rate and fat oxidation, possibly due to changes in substrate preferences. However, practical considerations such as optimal dosing and duration of supplementation need further investigation, as consuming high amounts of omega-3s through diet alone may not be feasible. The research is still in its early stages, and more studies are needed to understand how omega-3s influence muscle and mitochondrial function. In this clip, Dr. Chris McGlory explains the potential mechanisms by which omega-3s impact muscle mass and function.

A molecule composed of a ribonucleoside and two phosphate groups. ADP is an intermediary molecule between adenosine monophosphate (AMP) and adenosine triphosphate (ATP) and plays essential roles in cellular energy processes.
Tiny organelles inside cells that produce energy in the presence of oxygen. Mitochondria are referred to as the "powerhouses of the cell" because of their role in the production of ATP (adenosine triphosphate). Mitochondria are continuously undergoing a process of self-renewal known as mitophagy in order to repair damage that occurs during their energy-generating activities.
An ongoing assessment of the health and nutritional status of adults and children in the United States. NHANES data include findings from standardized physical examinations, laboratory tests, and interviews that cover various health-related topics.
A measure of red blood cell omega-3 fatty acid concentration. The omega-3 Index is a measurable risk factor for sudden cardiac death. People who have high blood concentrations (8 to 12 percent) of omega-3s are far less likely to die from all causes of premature death.[1]
