Tendons have a relatively poor blood supply and a slow turnover rate, which is why tendon problems take months rather than weeks to resolve. Nutrition can support that process — but it works alongside loading, not instead of it.
Where the evidence is reasonable
Collagen with vitamin C, timed before loading
The most interesting area. Some research suggests that taking around 15g of gelatin or hydrolysed collagen with vitamin C roughly an hour before loading may increase collagen synthesis — the timing appears to matter, since tendon blood flow rises with activity.
Evidence is promising but still developing, and effect sizes are modest. Worth trying; not worth expecting transformation.
Adequate total protein
Unremarkable but important. Roughly 1.6 to 2.0 grams per kilogram of bodyweight daily supports connective tissue repair as well as muscle. Insufficient protein is a genuine limiter for some people.
Vitamin C
Essential for collagen cross-linking — a true requirement rather than an enhancement. Deficiency impairs healing. Supplementing beyond adequacy doesn't appear to add much, so the goal is sufficiency.
Enough total energy
Repair is metabolically costly. Chronic under-eating, common in endurance athletes and people dieting hard, meaningfully impairs tissue healing.
Plausible but less certain
- Omega-3 fatty acids — anti-inflammatory effects are established; specific tendon-healing benefit is less clear
- Vitamin D — worth correcting if deficient, which is common at Canadian latitudes in winter; unclear benefit beyond sufficiency
- Magnesium and zinc — involved in tissue repair, matter mainly if you're deficient
Frequently oversold
- Proprietary "tendon repair" formulas at high prices
- High-dose antioxidants — which may actually blunt the adaptive response to loading
- Anything promising rapid healing
Things that work against you
Smoking measurably impairs tendon healing and is among the most significant modifiable factors. Heavy alcohol intake, chronic sleep restriction and poorly controlled blood sugar all work against repair as well.
Putting it together
Eat enough total calories and protein, keep vitamin C adequate, consider collagen with vitamin C before your loading sessions, correct any deficiencies — and put the bulk of your effort into the progressive loading program.
