In the world of fitness and bodybuilding, certain supplements have become staples: whey, creatine, BCAAs… and collagen. Often associated with skin health, its benefits extend far beyond that. It plays a direct role in the strength of joints, tendons, ligaments, and bones—structures that are essential for effective training and long-term progress. So can collagen really help improve your athletic performance? It’s time to take a closer look at the benefits of collagen so you can decide for yourself!
Collagen: a structural protein in your body
Collagen is quite simply the most abundant protein in your body—nothing less. It accounts for about 30% of the proteins in the human body and forms the basis of connective tissues such as tendons, ligaments, cartilage, and skin. You can think of collagen asthe framework that keeps the body strong and stable.
There are several types of collagen, but three are particularly important: type I, type II, and type III.
The problem with collagen is that the body’s natural production of it declines over time. It begins to decrease in adulthood, around age 25, and may be even more depleted in athletes. As a result, tissues gradually become less resilient and less elastic, which affects performance.
Stronger joints for longer workouts
When you exercise regularly, the joints are subjected to a great deal of stress: heavy weights in strength training, impact from running, repetitive movements in cross-training…
The cartilage that protects these joints contains a large amount of collagen. It acts as a natural shock absorber. Several scientific studies have examined the effects of collagen supplementation in athletes, and the results are surprising.
A study found that daily consumption of 10 g of hydrolyzed collagen over a 24-week period reduced joint pain in athletes (Clark et al., 2008).
Another scientific journal also notes that collagen peptides may help improve joint function and comfort during physical activity (Zdzieblik et al., 2021).
As you can see, collagen plays a major role in helping you keep moving forward without being held back by sore joints.
Tendons and ligaments: key tissues for athletic performance
While your muscles generate force, tendons and ligaments transmit it. And in between, joints provide stability. However, all of these structures are largely made up of collagen. During intense training, they are subjected to repeated micro-stresses. Over time, the tissues can weaken, increasing the risk of injury.
Some research suggests that collagen peptides may:
- support the structure of the tendons;
- improve their mechanical strength;
- promote tissue repair after exercise.
A study has shown that supplementation with gelatin (rich in collagen) combined with vitamin C increases collagen synthesis in connective tissues after exercise (Shaw et al., 2017). Sounds promising, doesn’t it?
The Benefits of Collagen for Sports Recovery
After an intense workout, the body needs to repair many types of tissue: muscles, tendons, ligaments, and cartilage. Collagen contains specific amino acids such as:
- wisteria;
- proline;
- hydroxyproline.
These compounds play a direct role in the repair of your connective tissues. Some research suggests that collagen supplementation helps to:
- reduce exercise-related injuries;
- promote tissue repair ;
- improve exercise tolerance.
Even though collagen does not replace complete proteins such as those used for muscle gain, it complements your sports nutrition strategy by adding another building block.
Beyond exercise: a bonus benefit for your skin
Chances are you’re familiar with collagen for its skin benefits. And the results speak for themselves: collagen helps improve the skin’s elasticity, hydration, and firmness.
A meta-analysis has shown that supplementation with hydrolyzed collagen for 8 to 12 weeks can improve skin elasticity and reduce the signs of skin aging (Choi et al., 2019).
Even if that’s not your main reason for taking collagen, it’s a very welcome side effect!
How can you incorporate collagen into your fitness routine?
As with many dietary supplements, consistency is the key to success. To easily incorporate it into your daily routine, try adding collagen powder to:
- a protein shaker;
- a smoothie;
- a hot drink;
- yogurt or oatmeal.
The InShape Nutrition Collagen has been formulated to meet the specific needs of active individuals. Its formula is based on Peptan®-labeled hydrolyzed type I collagen peptides, combined with vitamin C, a nutrient involved in the body’s natural collagen synthesis. This combination is designed to support the health of connective tissues that are particularly stressed by exercise.

In sports, progress doesn't depend solely on your muscles. Joints, tendons, and ligaments play an equally essential role. Collagen works specifically within these tissues to help you:
✔️ Support heavy loads.
✔️ Do back-to-back sessions.
✔️ Reduce joint pain.
✔️ Ensure proper recovery.
While it’s not a miracle product, it helps your body cope with the demands of training. Are you interested in gaining muscle mass ? We’ve got just what you need! Check out our dietary supplements designed to help you push your limits.
