Evidence File #008: Collagen and Gut Health — What Researchers Have Actually Found
Evidence File #008: Collagen and Gut Health — What Researchers Have Actually Found examines the published scientific research behind Peptan® collagen peptides and gut health. Discover what researchers found when investigating exercise-induced gastrointestinal stress, intestinal barrier function and digestive comfort, and why the findings highlight the importance of evidence over marketing. Rather than making exaggerated claims, this article explains what the science currently supports, where the evidence is still emerging, and why CollagenX exclusively uses clinically researched Peptan® collagen peptides.
Evidence File #007: Does Collagen Really Get Absorbed? The Science Explained
Evidence File #007: The Absorption Studies examines one of the most common questions about collagen supplementation: does collagen actually get absorbed? This article explores the published Peptan® research tracking collagen peptides through digestion and into the bloodstream, explaining how scientists have identified bioactive collagen peptides after supplementation and why this challenges the misconception that collagen is simply broken down like any other protein. Discover why absorption research is essential to understanding collagen science and why CollagenX exclusively uses clinically researched Peptan® collagen peptides.
Evidence File #006 — Collagen and Sleep: An Unexpected Area of Research
Evidence File #006: Collagen and Sleep — An Unexpected Area of Research explores one of the newest and most surprising areas of collagen science. Discover why researchers investigated Peptan® collagen peptides and sleep quality, what a published human clinical trial found about sleep fragmentation and next-day cognitive performance, and why ingredient-specific research matters when evaluating collagen supplements. This article separates scientific evidence from marketing claims and explains why CollagenX exclusively uses clinically researched Peptan® collagen peptides.
Evidence File #005 — Collagen for Exercise Recovery — Separating Evidence from Hype
Evidence File #005: Exercise Recovery explores the published scientific research behind Peptan® collagen peptides and recovery after exercise. Rather than relying on marketing claims, this article examines the human clinical studies investigating muscle soreness, functional recovery, exercise-induced muscle damage and connective tissue recovery. It also explains why some studies report positive findings while others report neutral outcomes, demonstrating what genuine evidence-based nutrition looks like. Discover why CollagenX exclusively uses clinically researched Peptan® collagen peptides and why ingredient-specific research matters when choosing a collagen supplement for recovery.
Evidence File #004 — Collagen for Bone Health: What the Evidence Says
Evidence File #004: Bone Health examines the published scientific research behind Peptan® collagen peptides and bone health. Discover why healthy bones depend on more than calcium alone, explore the evidence investigating collagen's role in bone metabolism and bone remodelling, and learn why ingredient-specific research matters when choosing a collagen supplement. This article reviews the published Peptan® studies, explains what the science currently supports, and shows why CollagenX exclusively uses clinically researched Peptan® collagen peptides instead of generic collagen ingredients.
Evidence File #003 — JOINT HEALTH: Understanding the Science Behind Collagen and Healthy Joints
Almost every collagen brand claims to support healthy joints, but how many can point to published research on the exact collagen ingredient inside their product? In Evidence File #003, we explore the biology of healthy joints, the evolution of collagen science, and the clinical research behind specialised collagen ingredients such as Peptan® and Colartix®. Discover why ingredient identity matters, why not all collagen ingredients are scientifically interchangeable, and how to separate evidence from marketing claims.
Evidence File #002: Collagen for Hair Loss — Separating Science from Marketing
Evidence File: The Hair Studies explores the emerging science behind collagen peptides and hair health. Rather than relying on marketing claims, this article examines the published Peptan® research investigating how collagen peptides interact with living human hair follicles and influence key biological processes involved in healthy hair growth. Learn what the latest science does—and doesn't—tell us about collagen and hair, why mechanistic research is important, and how CollagenX's commitment to ingredient-specific evidence sets it apart from collagen brands making unsupported hair claims.
Evidence File #001: Clinically Proven Collagen for Skin? What the Studies Really Show
Evidence File #001: The Skin Studies explores one of the biggest misconceptions in the collagen industry: that all collagen peptides are backed by the same science. They aren't. This article examines the published Peptan® clinical studies on skin hydration, elasticity, firmness, wrinkles and nail health, and explains why ingredient-specific research matters. Learn how to distinguish evidence-based collagen from generic collagen, and discover why CollagenX exclusively uses clinically researched Peptan® collagen peptides.
Evidence File #009: The Discovery of Metabolic Collagen - How a New Generation of Collagen Peptides Is Changing Metabolic Science
What happens when collagen peptides do more than provide amino acids? New research is revealing a surprising connection between specific collagen peptides, GLP-1 and blood glucose control. Evidence File #010 examines the latest human study, showing how a specially selected collagen peptide composition influenced GLP-1 and GIP, gastric residence and the rise in blood glucose after a meal. The research reveals why the type and composition of collagen peptides matter, and why metabolic effects cannot be assumed from ordinary collagen.
