In this episode, Brodie breaks down a brand-new 2026 systematic review investigating whether collagen supplementation truly improves tendon health, recovery, and performance. With conflicting advice from experts and unclear evidence in the past, this paper helps clarify what actually worksāand more importantly, how to apply it to your training.
Paper: Collagen Supplementation on Tendon-Related Structural and Performance Outcomes: A Systematic ReviewĀ
Key Takeaways
- Ā Collagen can improve tendon structure and stiffnessābut only when combined with proper strength trainingĀ
- Dosage matters: 15ā30g appears more effective than lower dosesĀ
- Timing matters: ~60 minutes before training aligns with peak amino acid availabilityĀ
- Vitamin C enhances the process, helping collagen synthesis and cross-linkingĀ
- Ā Collagen does NOT improve muscle strength beyond what training alone achieves
Bottom line: collagen seems tendon-specific, not a general performance enhancer
Training Requirements
- Ā Must include structured resistance training
- Ā Target 70ā90% of 1RM (heavy loading)
- Ā Tendons need a strong mechanical stimulus to adapt
Collagen without loading = minimal benefit
Final Thoughts
This paper helps move us from confusion to clarity.
Collagen isnāt a magic fixābut when used strategically alongside heavy strength training, it may:
- Ā Improve tendon structureĀ
- Ā Increase stiffnessĀ
- Ā Enhance long-term resilienceĀ
In other words, itās a potential amplifierānot a replacementāfor good rehab and training principles.
