Sarah
Ultrarunner, Third Place, Spine Race Sprint 2024
“Since my chronic Achilles injury stopped me running for almost a year, I’ve taken Run Easy religiously! I add my collagen either to orange juice or into my protein shake after a workout. I believe as a very active ultra runner who has had tendon issues, this is an essential part of my supplement toolkit to help keep me injury free!”

Marathon Runner
“Following ankle ligament reconstruction surgery, my recovery is ahead of where it should be by about 4 weeks. My physio believes that taking the Run Easy collagen every day is one of the main reasons why I’m well ahead. I’m starting to run again 12 weeks since surgery whereas 16 weeks is the usual recovery time!”

SCIENCE
The number and quality of research into the positive affect’s collagen has on runners’ soft tissue injuries is growing. We have summarised them in the following blog article:
Key Findings on Marine Collagen for Runners
• Document: Can collagen help runners?
• Link: https://proteinrebel.com/blogs/blog/can-collagen-help-runners
Joint Health and Injury Prevention
• Key Finding: Collagen is a vital protein for the body's connective tissues, including tendons, ligaments, and cartilage. Since a runner's natural collagen production declines after age 20, supplementation is a way to help the body withstand the demands of running. Studies have found that collagen peptides can reduce joint pain in athletes, especially in the knees, and improve the mechanical properties of the Achilles tendon.
Muscle Soreness and Recovery
• Key Finding: The blog cites a study showing that collagen peptides can alleviate exercise-induced muscle soreness and accelerate recovery after intense exercise. This helps runners get back to their training faster and with less discomfort.
If you would like to research the science behind collagen the following research papers are good places to start:
1. Reduce Joint Pain While Running by up to 50%
• Document: This claim is based on multiple studies. One study, "24-Week study on the use of collagen hydrolysate as a dietary supplement in athletes with activity-related joint pain," showed a statistically significant improvement in joint pain.
• Link: https://www.researchgate.net/publication/5435547_24-Week_study_on_the_use_of_collagen_hydrolysate_as_a_dietary_supplement_in_athletes_with_activity-related_joint-pain
• Key Finding: After a 24-week trial, athletes who took a collagen supplement experienced a significant reduction in joint pain during activity, leading to less pain and discomfort.

2. Faster Recovery & Less Soreness: Improve Muscle Function by 8%
• Document: This statistic is supported by a study on exercise-induced muscle soreness.
• Link: https://www.tandfonline.com/doi/abs/10.1080/15502783.2023.2206392
• Key Finding: Collagen supplementation was shown to alleviate muscle soreness after strenuous exercise, helping improve muscle strength and function in the recovery period.

3. Heal Your Tendons: Supplementation Can Improve Achilles Tendon Health
• Document: This claim is from a study on Achilles tendon health.
• Link: Oral Supplementation of Specific Collagen Peptides Combined with Calf-Strengthening Exercises Enhances Function and Reduces Pain in Achilles Tendinopathy Patients - PMC
• Key Finding: Combining specific collagen peptides with targeted exercises significantly enhanced tendon function and reduced pain for athletes dealing with Achilles tendinopathy.

4. Strengthen Your Bones & Joints: Tendons are up to 85% Collagen
• Document: The statistic is supported by the composition of tendons, a well-established fact in physiology.
• Link: Collagen support | ASC
• Key Finding: Collagen is a fundamental component of the body's connective tissues. Tendons, which connect muscle to bone, are composed of 60-85% collagen, making it essential for their strength and elasticity.

5. Run with Less Injury Risk: Collagen Can Increase Tendon Stiffness by 18%
• Document: This statistic is from a study on female soccer players.
• Link: https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2023.1089971/full
• Key Finding: Supplementing with collagen alongside training increased patellar tendon stiffness, which is a key indicator of the tendon's ability to handle stress and may lead to a lower risk of injury.
Runners ask us
Runners’ questions
“I’m managing a running injury — knees, achilles, tendons. Will this actually help?”
Collagen can’t replace expert intervention if you’re injured. If you have an injury, see a medical professional/physio first. What collagen does is provide the daily amino acids your body uses to rebuild tendons, ligaments and cartilage. It can be taken daily alongside your rehab and our customers report it as a meaningful part of their recovery.
“66 year old male. Ruptured my Achilles in October 2024. Scan at six months shows it had healed. Now back to all pre-injury activities.”
— Loox review, 5★“I’ve noticed my knees and ankles click when I get up. Will this help?”
Yes — this is one of the first changes customers describe. Clicking joints are often a sign that cartilage and soft tissue are under stress. Collagen peptides support the structural proteins that keep those tissues healthy. Most runners notice a difference around 8–12 weeks of daily use.
“My knees and ankles no longer click when I get up off the sofa. Definitely feel it is improving my overall joint health and my run recovery.”
— Loox review, 5★“I accidentally ran out. How quickly will I notice if I stop?”
Most runners notice a break in collagen use within 1–2 weeks of stopping. Collagen is a daily maintenance input — when you stop providing the amino acids your body needs, the repair cycle slows. It’s exactly why we offer a subscription: running out mid-habit undermines the 8+ weeks you’ve already built. You can pause anytime.
“I accidentally ran out a few weeks ago and the difference in the days I wasn’t using it was very noticeable. My achy legs and feet reappeared!”
— Loox review, 5★“My hair and nails have always been weak. Will taking this help with that too?”
Almost certainly yes, though we don’t lead with it. Type I collagen is the same structural protein your body uses for hair and nails as it does for tendons. The benefit usually shows up around 4–6 weeks in, and it catches almost every customer by surprise.
“My hairdresser has even started to promote Protein Rebel collagen since seeing the difference in my hair condition!”
— Loox review, 5★“I already take whey protein after my runs. Do I need collagen as well?”
Yes — collagen and whey do completely different jobs. Whey rebuilds muscle fibres. Collagen rebuilds tendons, ligaments and cartilage using a unique combination of amino acids that barely exist in whey (glycine, proline, hydroxyproline). Your protein shake doesn’t reach your tendons. Collagen does. Most serious runners use both.
