Understanding the Different Types of Collagen
There are at least 28 identified types of collagen, but the most common ones are Type I, II, and III. These collagen types have different functions and locations in the body, which makes knowing the right one for your health goals important.
- Type I: This is the most abundant collagen in the body, found in the skin, tendons, ligaments, and bones. It gives structure and elasticity. Supplements often feature this type for skin, hair, and nail health.
- Type II: This is the main component of cartilage, the flexible tissue that cushions your joints. It's crucial for joint flexibility, mobility, and shock absorption.
- Type III: Found alongside Type I in the skin, muscles, and blood vessels, contributing to skin elasticity and organ health.
How to Identify Type 2 Collagen Supplements
Several key indicators can help you determine if a supplement contains Type II collagen:
- Source of Collagen: This is the most reliable indicator. Type II collagen is almost always derived from chicken sternum cartilage. If a supplement lists bovine (cow) hide or marine (fish) scales as the primary source, it likely contains Type I and III, not Type II. Always read the ingredient list carefully.
- Type of Formulation: Type II collagen is often sold in an "undenatured" or "native" form. Undenatured means the collagen has not been heavily processed with high heat, acids, or enzymes, preserving its natural structure. This allows it to work differently in the body, primarily by interacting with the immune system to reduce inflammation and support cartilage growth. In contrast, Type I and III are usually hydrolyzed, meaning they are broken down into smaller peptides for easier absorption.
- Product Form: Due to its undenatured nature, Type II collagen is typically available in capsule or tablet form to protect its structure. Hydrolyzed collagen (Types I and III) is most commonly found as a dissolvable powder.
- Intended Use or Marketing: Products containing Type II collagen are specifically marketed for joint health, arthritis relief, and improved mobility. If the label emphasizes benefits for skin, hair, and nails, it's more likely a Type I and III supplement.
Choosing Between Undenatured and Hydrolyzed Collagen
The choice between undenatured (Type II) and hydrolyzed (Type I/III) collagen depends on your health goals. The following table provides a clear comparison.
| Feature | Undenatured Type II Collagen | Hydrolyzed Collagen (Type I & III) |
|---|---|---|
| Primary Source | Chicken sternum cartilage | Bovine hides, fish scales, or bovine bone |
| Formulation | Undenatured (preserved native structure) | Hydrolyzed (broken down peptides) |
| Typical Form | Capsules or tablets | Powders, liquids, or gummies |
| Key Benefit | Targeted joint and cartilage support; modulates immune response | General skin, hair, bone, and gut support; provides amino acid building blocks |
| Absorption | Absorbed intact to interact with immune cells in the gut | Digested and absorbed as smaller peptides |
| Best For | Individuals with joint pain, arthritis, or looking for specific joint support | General wellness, improving skin elasticity, and strengthening hair and nails |
Practical Tips for Verifying Your Supplement
To be absolutely certain about the type of collagen you are purchasing, follow these simple steps:
- Read the Label: The product label should clearly state the type of collagen and its source. Look for phrases like "undenatured Type II collagen," "UC-II®" (a patented form), or "from chicken sternum cartilage." If it just says "collagen peptides" without specifying the type, it's likely a hydrolyzed Type I/III blend.
- Research the Brand: High-quality brands are transparent about their sourcing and processing. Check the company's website for detailed product information and third-party certifications, such as NSF International, which ensures adherence to quality standards.
- Consider the Price: Undenatured Type II collagen is often a more specialized ingredient and may be priced differently than general hydrolyzed collagen powders. While price isn't a perfect indicator, it can offer a clue as to the type of product.
The Takeaway
For those seeking focused joint support, ensuring you select a supplement containing Type II collagen is paramount. By understanding the sourcing and formulation, you can confidently choose the right product for your needs. Always look for undenatured Type II from chicken sternum cartilage, typically found in capsule form, and check the label for clarity on its purpose. Remember that Type II works differently than the more common Type I and III, which are primarily aimed at skin and hair benefits. When in doubt, consult a healthcare professional to guide your supplement choices.

Conclusion
Understanding how to know if collagen is type 2 requires attention to specific product details. By focusing on the source (chicken sternum cartilage), the formulation (undenatured), and the intended use (joint support), consumers can make informed decisions. This distinction is vital because Type II collagen has a unique mechanism of action targeted specifically at cartilage and joint health, differentiating it from the more general benefits associated with Type I and III collagen. For optimal results, selecting the right collagen type based on your health goals is the most effective strategy.
Summary of Key Differences
- Sourcing matters: Type II is derived from chicken sternum cartilage, while Type I and III typically come from bovine or marine sources.
- Formulation varies: Type II is often undenatured and taken in capsules, whereas Types I and III are hydrolyzed peptides in powder form.
- Benefits differ: Type II is for targeted joint and cartilage support, while Types I and III focus on skin, hair, and bone health.
- Read the label carefully: Look for "undenatured Type II" or "chicken sternum cartilage" to confirm the specific type.
- Marketing is a clue: If a product promotes joint health and mobility, it likely contains Type II collagen.
