Collagen is a protein that occurs abundantly in the human body and is often highlighted in nutrition and supplements. Understanding the different types of collagen can help you make informed product choices. In this article, we explain the meaning and origin of collagen types I, II, and III.
Why Are Types I, II, and III Important?
There are at least 28 different types of collagen, but in nutrition and supplements, the focus is mainly on types I, II, and III. These types differ in structure, origin, and application.
Type I Collagen
- Where is it found? Type I is the most common collagen type in the body.
- Sources: typically derived from bovine, fish, or porcine skin.
- Use in products: commonly found in supplements such as collagen powders and capsules.
Type II Collagen
- Where is it found? Primarily found in cartilage.
- Sources: usually derived from chicken cartilage.
- Use in products: used in specific type II collagen supplements.
Type III Collagen
- Where is it found? Often found alongside type I, for example in organs and skin.
- Sources: obtained from bovine or porcine sources.
- Use in products: often included in type I & III collagen combinations.
How to Choose the Right Type of Collagen
When selecting a collagen product, consider the following aspects:
- Type of collagen: choose type I (skin, bones), type II (cartilage), or a combination of type I + III.
- Source: check whether it’s marine (fish), bovine, porcine, or chicken cartilage.
- Form: hydrolyzed collagen (peptides) offers better solubility.
- Transparency: quality brands clearly list the types, amounts, and sources used.
Typical Applications per Collagen Type
You can match collagen products to your preferences. For example:
- Type I (and III): popular in powders and capsules often aimed at general collagen intake.
- Type II: typically found in supplements based on cartilage sources.
- Combination products: contain multiple types for a broader composition.
Hydrolyzed vs Native Collagen
Offering supplements is easier with hydrolyzed collagen:
- Native collagen retains its original structure and does not dissolve in cold water.
- Hydrolyzed collagen is broken down into collagen peptides, which improves solubility.
What to Look for on the Label
Key elements to identify on a collagen product label:
- Collagen type(s) (I, II, III)
- Source (marine, bovine, chicken)
- Form (hydrolyzed, peptides)
- Amount per serving
- Allergen information (e.g., fish, beef)
- Certifications or quality seals (Non‑GMO, vegan‑GERM)
Frequently Asked Questions
1. Is there plant-based collagen?
There is no true plant-based collagen. However, some ingredients may support collagen production, but these are not collagen themselves.
2. Can I combine different types?
Yes, some products combine type I and III, or contain type II only. Always read the label and see what fits your preferences.
3. Is collagen suitable for vegetarians or vegans?
Collagen is of animal origin. Vegans may opt for plant-based alternatives such as amino acids or products that support collagen formation through diet.
How This Information Helps You Choose
By clearly explaining the types of collagen and their sources, you can make a more informed choice that suits your reason for using collagen.
