Flexibility Improvement
Increased range of motion and joint mobility.
TL;DR
Range of motion improves with consistent stretching and full-range strength training, not with supplements. Collagen with vitamin C may support the connective tissue you are loading, but only alongside training.
Why It Matters
Restricted range of motion contributes to compensatory movement patterns, injury risk and, in older adults, reduced functional independence. Hypermobility carries its own injury risk, so more flexibility is not always better.
How to Measure
Biomarkers
Optimization Protocol
Stretch each target area for 60 seconds daily, five days a week, and train strength through full range, which improves mobility as effectively as stretching. Collagen 15 g with 50 mg vitamin C, taken 30-60 minutes before loading, may support tendon adaptation. Warm tissue before end-range work.
