Pad rounds, bag work, sparring and clinch - Muay Thai and kickboxing place specific and repeated impact stress on the wrists, elbows, knees and shins. Here's an honest look at where collagen fits for UK fighters.
Muay Thai and kickboxing are among the most physically demanding combat sports - combining high-volume striking, kicking, knee and elbow work with the impact absorption of pad rounds, bag sessions and sparring. For UK fighters training regularly, the cumulative stress on wrist ligaments, elbow tendons, knee connective tissue and shin periosteum is significant. Here's what collagen actually is, and what the evidence does and does not show.
What Muay Thai and Kickboxing Do to Your Connective Tissue
Striking sports are unique in that they combine the overuse stress of high-repetition training with the acute impact stress of striking surfaces - bags, pads, and in sparring, other fighters. Every punch loads the wrist ligaments and knuckle connective tissue. Every kick loads the shin periosteum and knee ligaments. Every elbow strike loads the elbow tendons. Every knee strike loads the patellar tendon and knee joint.
For fighters training 4–6 sessions per week, this means connective tissue is absorbing both chronic overuse stress and acute impact stress simultaneously - a combination that makes structural maintenance more important than in almost any other sport.
Where Collagen Actually Fits for Striking Athletes
The wrist ligaments, shin periosteum, knee ligaments, elbow tendons and shoulder connective tissue most stressed by striking sports are all primarily collagen - a structural protein that forms the framework of those tissues. That is anatomy, and it is the reason collagen comes up in combat sport conversations at all.
Hydrolysed collagen peptides are a dietary protein source unusually rich in glycine, proline and hydroxyproline - the amino acids that are most abundant in the body's own collagen, and that are present in far lower proportions in muscle-meat and dairy protein. That is a statement about composition, not about what the powder will do for you.
Research has investigated whether collagen taken before exercise affects markers of collagen turnover. Published findings should be interpreted in the context of each study's ingredient, dose, design, duration, participant group and outcomes measured, and none of them were run in Muay Thai or kickboxing athletes. Studies in this area typically use 5–15g daily, measured at 8–24 weeks.
Revayo Prime provides 14.77g of FORTIGEL® Type I hydrolysed collagen peptides per serving alongside 189.9mg Vitamin C - which contributes to normal collagen formation for the normal function of cartilage, bones, skin, blood vessels, gums and teeth. 14.77g sits inside the 5–15g range used in the published research.
What Collagen Is and Isn't
- It is a structural protein: collagen makes up roughly 30% of the protein in the human body and forms the framework of ligament, tendon, bone and cartilage - including the wrist, shin, knee and elbow structures striking loads hardest
- It is, nutritionally, a protein powder: one serving is a concentrated dietary source of glycine, proline and hydroxyproline
- The Vitamin C part is the authorised bit: Vitamin C contributes to normal collagen formation for the normal function of cartilage, bones, skin, blood vessels, gums and teeth
- It is not a treatment: collagen is a food supplement, not a treatment for wrist pain, shin pain, tendinopathy or any other diagnosed injury
- It is not protective equipment: nothing in a tub replaces hand wraps, gloves, shin conditioning done properly, or a sensible sparring schedule
- The research is thin here: studies in this area typically use 5–15g daily, measured at 8–24 weeks, and none of them recruited striking athletes
How Men Typically Take Collagen
Collagen Is Part of the Solution - Not All of It
- Wrapping and equipment: proper hand wrapping and quality gloves reduce the impact forces transmitted to wrist ligaments during every striking session - non-negotiable for high-volume training
- Technique first: poor punching mechanics increase wrist and elbow stress - time with a coach on mechanics is the single most useful thing most fighters can do
- Progressive shin conditioning: gradual increase in bag and pad work intensity rather than sudden high-volume sessions - the most common cause of shin periosteum issues in newer fighters
- Load management: balancing hard sparring sessions with technical work - cumulative impact stress across a week is the primary driver of chronic striking sport injuries
- Daily collagen + Vitamin C: a dietary addition on top of the above, where Vitamin C contributes to normal collagen formation for the normal function of cartilage, bones, skin, blood vessels, gums and teeth

Research context
Research relevant to Muay Thai and kickboxing athletes uses specific collagen peptide ingredients, doses, study designs and participant groups. Findings should be interpreted within those study conditions rather than treated as proof of a guaranteed result for every reader.
Published findings relate to the ingredient and outcomes studied. Revayo Prime is a food supplement and is not a substitute for professional advice, rehabilitation or medical care.
Vitamin C contributes to normal collagen formation for the normal function of cartilage, bones, skin, blood vessels, gums and teeth. This authorised claim relates to the Vitamin C in Revayo Prime.
