Collagen peptides and protein powder are both protein-based supplements, and they're often confused — or used interchangeably — by people who assume any protein supplement will do the same job. In practice, they serve fundamentally different purposes, have distinct amino acid profiles, and the research supporting each applies to different outcomes. Understanding the distinction is…
Joint health represents one of the most compelling evidence bases for collagen peptide supplementation, with randomised controlled trials demonstrating measurable benefits for pain reduction, cartilage preservation, and functional mobility across athlete, elderly, and osteoarthritis populations. This review examines the evidence specifically for joint and connective tissue applications.Collagen Biology in Joints: What's at Stake

The choice between marine and bovine collagen is one of the most frequently debated questions in collagen peptide research. Both sources produce hydrolysed collagen with overlapping amino acid profiles and similar mechanisms of action, yet they differ in ways that can matter for specific research applications, dietary considerations, and bioavailability profiles.

Peptide Half-Life Explained: plain-English summary of published research, mechanism, evidence limits and laboratory handling. For laboratory research use only.
Skin represents the most extensively studied application of collagen peptide research. With the global collagen market projected to exceed £5 billion, the scientific scrutiny applied to skin claims has intensified significantly since 2018 — producing a body of randomised controlled trial data that separates evidence-based findings from marketing claims.
This article reviews what the research…
What Are Collagen Peptides?
Collagen peptides — also called hydrolysed collagen or collagen hydrolysate — are short-chain amino acid sequences derived from the breakdown of full-length collagen protein. Through enzymatic hydrolysis, long collagen molecules are cleaved into smaller fragments, typically 2–10 amino acids in length, producing a bioavailable form that dissolves readily in water and…
What Is Lyophilisation?
Lyophilisation, also known as freeze-drying, is a process that removes water from peptides whilst preserving their molecular structure and biological activity. The process works in three stages: first, the peptide solution is rapidly frozen to extremely low temperatures (typically below -40°C); second, during primary drying, the frozen solution is placed under vacuum…
What is Bacteriostatic Water?
Bacteriostatic water is sterile, pyrogen-free water containing 0.9% benzyl alcohol as a preservative. This combination creates an isotonic solution (matching blood osmolarity) whilst the benzyl alcohol acts as a bacteriostatic agent — inhibiting bacterial growth without killing existing microorganisms. In laboratory contexts, bacteriostatic water serves as the standard reconstitution medium for…

What Are Research Peptides?
Research peptides are short chains of amino acids, typically comprising 2 to 50 amino acids linked together. To understand peptides, it's helpful to know how they differ from proteins. Whilst both peptides and proteins are made from amino acids, the distinction lies in their size. Peptides contain fewer amino acids than…
