These tight junction proteins permit the paracellular movement of molecules via two different pathways, which have been named the pore or leak pathway

In a 2023 RCT at the University of Vienna, 55 male participants consuming 15 grams of SCP daily while performing concurrent training for 12 weeks showed significantly improved recovery markersincluding maximal voluntary contraction, rate of force development, and countermovement jump heightfollowing 150 drop jumps.9 A companion study from the same group demonstrated that the SCP group had significantly lower blood levels of myoglobin, creatine kinase, and lactate dehydrogenase after a second bout of muscle-damaging exercise, indicating reduced acute muscle stress and improved musculotendinous structural integrity.10 Caption: Twelve weeks of daily 15-gram collagen peptide supplementation combined with concurrent training significantly reduced exercise-induced muscle-damage markers (left) and improved one-hour running time-trial performance (right) in recreationally active men
