Collagen Guide: 8 Articles from KINGRAY Academy
KINGRAY ACADEMY · COLLAGEN
Understanding collagen: from tissues to scientific studies
What is collagen, how do its types differ, and what role does it play in skin, joints and blood vessels? This guide connects eight KINGRAY Academy articles and helps distinguish how the human body works from what research has actually tested.
What is collagen, and why does the body need it?
Collagen is a family of structural proteins. It is found in skin, bones, cartilage, tendons, ligaments and the connective tissues of blood vessels and organs; its types differ in structure and distribution. [1]
The body makes its own collagen. This process uses amino acids and also requires vitamin C. A nutrient’s role in normal body function does not, however, prove that a higher dose will produce a better result. [2]
Three terms worth distinguishing
- Source: Marine or bovine describes where the raw material comes from.
- Type: The labels I, II and III distinguish collagen proteins in the original tissues.
- Processing: Hydrolysed means broken down into smaller peptides; it is not another type alongside I, II and III.
Reading research with realistic expectations
When reading about skin, joints or a particular peptide, pay attention to:
- What was studied: the exact ingredient or formulation and the dose used.
- Who took part and for how long: participant numbers, age, health status and follow-up duration.
- What it was compared with: the control group and how participants were assigned.
- What was measured: hydration, mobility or personal experience, for example; also consider funding and study limitations.
One study’s findings cannot automatically be applied to every person or every collagen product. The individual articles explain the supporting evidence and its limitations in more detail. [3]
Questions to help you find your way
Is collagen found only in the skin?
No. It is also found in bones, cartilage, tendons, ligaments and other connective tissues.
Is marine collagen automatically better than bovine collagen?
The source alone cannot tell us that. The specific ingredient, composition and evidence for the use being studied need to be assessed.
Is hydrolysed collagen another type of collagen?
No. Hydrolysis means processing collagen into smaller peptides, whereas types I, II and III refer to different collagen proteins.
Does smoother-looking skin prove that the body has made more collagen?
Appearance alone does not prove this. Hydration, cosmetics and lighting can all affect how skin looks.
Which article should I start with?
Start with article 01 on collagen in the body, followed by article 02 on types and processing. Then choose the topics that interest you.
