What is Hydrolysed Collagen?
Hydrolysed collagen, also known as collagen peptides or collagen hydrolysate, is a form of collagen that has been broken down into smaller protein fragments. This process, called hydrolysis, uses water and enzymes to reduce the large collagen molecules, making them easier for the body to digest and absorb. When you consume a hydrolysed collagen supplement, you are not directly providing your body with a specific type of intact collagen, but rather with the building blocks (peptides and amino acids) that your body can use to produce its own collagen where it is needed.
The Source Determines the Type
Since hydrolysis is a manufacturing process, a supplement's collagen type is determined by its animal source before it is broken down. The most common sources and their associated collagen types are:
- Bovine Collagen: Derived from cows (hides, bones), this is a rich source of Type I and Type III collagen. It is often used for skin, bone, and connective tissue support.
- Marine Collagen: Extracted from fish (scales, skin), marine collagen is primarily composed of Type I collagen, which is praised for its high bioavailability. It is a popular choice for skin health.
- Chicken Collagen: Sourced from chicken sternum cartilage, this is the main source of Type II collagen. It is specifically beneficial for joint and cartilage health.
Type 1 vs. Type 2 Hydrolysed Collagen
The primary difference between hydrolysed Type 1 and Type 2 collagen lies in their function, based on where the original collagen is primarily found in the body. While both are broken down into peptides, their distinct amino acid profiles can influence how the body utilizes them.
Hydrolysed Type 1 for Skin, Bones, and Hair
Because Type I collagen is the most abundant collagen in the human body, found in skin, bones, tendons, and ligaments, supplements derived from Type I sources are often marketed for these benefits. Hydrolysed marine or bovine collagen can support:
- Skin elasticity and hydration, reducing the appearance of fine lines and wrinkles.
- Bone mineral density and overall bone health.
- Stronger hair and nails.
Hydrolysed Type 2 for Cartilage and Joints
Type II collagen is the main component of cartilage, the flexible connective tissue that cushions your joints. While Type II collagen is more famously used in its undenatured (non-hydrolysed) form for an immunomodulatory effect on joints, it can also be hydrolysed to provide amino acid building blocks specifically for cartilage repair and maintenance. Taking a hydrolysed Type II supplement is aimed at providing targeted support for joint health and function, which can be particularly beneficial for people with joint-related concerns like osteoarthritis.
Choosing the Right Hydrolysed Collagen
Your choice should depend on your specific health goals. If you are looking to primarily improve the appearance of your skin, hair, and nails, a hydrolysed Type I collagen is most suitable. For targeted support for joint and cartilage health, a supplement rich in hydrolysed Type II collagen would be the better option. For overall benefits, a multi-collagen supplement containing a blend of different types can be effective.
Comparison of Hydrolysed Collagen Types
| Feature | Hydrolysed Type 1 Collagen | Hydrolysed Type 2 Collagen |
|---|---|---|
| Primary Function | Supports skin elasticity, bone strength, hair, nails | Supports cartilage health, joint flexibility |
| Common Sources | Bovine hides, marine (fish) skin and scales | Chicken sternum cartilage |
| Bioavailability | Very high due to small peptides | Also high, though often consumed as undenatured for specific immune action |
| Ideal For | Anti-aging, skincare, overall tissue support | Joint support, cartilage repair, arthritis sufferers |
| Typical Supplement Form | Powder, capsules, liquids | Often capsules (if undenatured), or powder (if hydrolysed) |
Conclusion: It's About the Source
In short, the question "Is hydrolysed collagen type 1 or 2?" is based on a false premise. Hydrolysis is a processing method, not a type. The correct way to frame the question is to ask what type of collagen was hydrolysed. Supplements on the market contain collagen peptides from different animal sources, providing either Type 1 (from bovine or marine sources) for skin and bone benefits, or Type 2 (from chicken cartilage) for targeted joint support. Your health goals should guide you toward the right type of hydrolysed collagen product. Regardless of the type, ensure you choose a high-quality product for maximum bioavailability and effectiveness.
