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.
Adequate high-quality dietary protein is important for muscle protein synthesis. Although, emphasis on specific amino acids within protein, particularly the branched-chain amino acids, which include leucine, isoleucine, and valine, is probably not necessary for most people. It's the leucine that really counts, says Dr. Phillips, and if a person eats sufficient protein, they're probably consuming enough leucine. There are caveats for older adults, who might benefit from a little supplemental leucine to offset their lower protein intake. In this clip, Dr. Stuart Phillips explains the importance of dietary protein quality and the role of the amino acid leucine in muscle protein synthesis.

Muscle News
- Late life exercise may partly reset epigenetic aging in skeletal muscle.
- Endurance training may leave a mitochondrial "muscle memory" that enhances training adaptations after a period of inactivity.
- Lean pork stimulates more muscle protein synthesis after exercise than high-fat pork, despite equal protein content
- Cold-water immersion reduces muscle protein synthesis by 30% post-exercise, potentially inhibiting the uptake of essential nutrients for muscle repair and growth.
- Resistance exercise in older adults boosts levels of cardiotrophin-like cytokine factor 1—a myokine released during exercise—by nearly 70%, improving muscle strength, bone density, and metabolic functions.
