- Collagen is part of the connective tissue that helps you move, including tendons and ligaments.
- Research on specific collagen peptides shows promise for exercise-related joint comfort and running performance.
- The research looks at regular use over weeks, making collagen a routine to build rather than a race-day trick.
There’s a lot to love about a run: time outside, a clearer head, the satisfaction of showing up for yourself. Whether you’re working toward 26 miles or protecting a few mornings a week for movement, taking care of the body that gets you there deserves a place in the routine.
That’s where collagen gets interesting. You may know it from the skincare conversation, but it also helps give structure to the tissues involved in every stride. And researchers are finding reasons to pay attention to collagen peptides beyond their beauty credentials.
Why Runners Should Be Interested in Collagen
Your muscles get plenty of credit for a good run. Tendons transmit their force to your bones, while ligaments help stabilize your joints. Both rely on collagen for their structure. [1]
That connection explains the interest in collagen for runners. The next question is what happens when people add collagen peptides to their diets. Clinical trials are beginning to offer useful answers.
Collagen and Joints
In a 2021 trial, 180 active men and women with exercise-related knee discomfort completed 12 weeks of daily collagen peptides or a placebo. The collagen group reported a greater reduction in discomfort during activity. [2]
That is an encouraging finding for people who want movement to remain an enjoyable part of life. It points to a possible role for specific collagen peptides in joint comfort, rather than simply another reason to think about skin.
What About Running Performance?
A 2023 study paired a 12-week running and strength program with daily collagen peptides or a placebo. Among the 32 men who completed it, the collagen group improved the distance they covered in a one-hour running test more than the placebo group. [3]
The training still mattered: both groups improved. Collagen was studied as an addition to that consistent effort. The trial was small and involved men, so it is an encouraging signal rather than a prediction of anyone’s next race time.
Think in Routines
These studies make collagen worth considering as part of an active lifestyle. They also share something practical: participants took it regularly over weeks. Pairing it with an existing moment in your day, especially if it’s one you already look forward to, makes that kind of consistency easier.

FAQs
Is collagen good for runners?
Research on specific collagen peptides suggests potential benefits for exercise-related joint comfort and some performance outcomes. It is a promising addition to a routine; benefits depend on the product and individual. [2,3]
How long does collagen take to work?
The joint-comfort and running studies above assessed changes after 12 weeks of daily use. Think in weeks of consistency, while recognizing that a study timeline is not a guarantee of results. [2,3]
Can collagen help if my knee hurts when I run?
The joint-comfort research is encouraging, but persistent or worsening pain needs an assessment. Collagen should not be used to push through an injury.
