Collagen for Runners and Lifters: Tendons, Recovery and Muscle
Athletes use collagen for tendons and joints. Here is what studies on active people found, how they dosed it, and how it fits with whey and training.
Tendons and ligaments are made mostly of collagen, and they adapt more slowly than muscle. That’s why collagen has become popular with runners, lifters and team-sport athletes.
What the research suggests
Joint discomfort in active people
A 24-week study in university athletes found that 10 g of hydrolyzed collagen daily reduced activity-related joint discomfort compared with placebo. Results across later studies are mixed but generally modest.
Collagen before training
A small study found that gelatin plus vitamin C taken about an hour before short, intense exercise increased a blood marker of collagen production. The idea: have building blocks in circulation when tendons are loaded.
Muscle
Collagen is an incomplete protein and isn’t ideal for muscle building on its own. But one study in older men found 15 g a day with resistance training improved fat-free mass gains versus placebo.
A practical routine
| When | What |
|---|---|
| 30–60 min before training | 10–15 g collagen or gelatin + vitamin C (e.g. orange juice) |
| After training | Complete protein (whey, milk, eggs, meat) |
| Every day | Overall protein ~1.2–2 g per kg body weight for active people |
What collagen won’t do
- It won’t heal an injury on its own — load management and rehab matter most.
- It won’t replace sleep, recovery and total protein.
- Pain that doesn’t improve needs a physiotherapist or doctor.
Sports-safe products
If you compete, choose products certified by NSF Certified for Sport or Informed Sport, which test for banned substances.
Frequently asked questions
Does collagen help tendinitis?
Some rehab studies combine collagen with loading exercises, with promising but early results. Exercise-based rehab is the core treatment.
Collagen or whey after the gym?
Whey (or another complete protein) is better for muscle after training. Collagen fits best before training or at another time of day.
How long before collagen helps joints?
Studies ran for 3–6 months.
