The Different Names of Hydrolyzed Collagen
When navigating the world of collagen supplements, it's easy to get confused by the variety of names. Fortunately, several terms are used interchangeably to refer to the same product: collagen that has been processed to be more easily absorbed by the body. The most common alternative name for hydrolyzed collagen is collagen peptides. Another synonym you may encounter is collagen hydrolysate.
These different names reflect either the end product—peptides—or the process used to create it—hydrolysis. In its natural state, collagen is a large, complex protein with a triple-helix structure that is difficult for the body to digest and utilize efficiently. The hydrolysis process uses water and enzymes to break these large protein molecules into smaller, more manageable peptide chains. This fragmentation significantly increases the bioavailability of the supplement, meaning the body can absorb and distribute it more effectively.
Why Are There Different Names for the Same Thing?
The different terminology can be explained by examining the product from two angles: the final form and the manufacturing process. The term “collagen peptides” highlights the biological state of the product—short-chain amino acid compounds called peptides. The name “hydrolyzed collagen” describes how it was made—through the process of hydrolysis. While there was a trend in recent years towards using the name “collagen peptides” to emphasize the bioactive nature of the ingredient, both terms are considered equally valid.
The Production Process: Hydrolysis vs. Gelatin
Understanding how hydrolyzed collagen is made also clarifies the distinction from related products like gelatin. Both hydrolyzed collagen and gelatin are derived from native collagen, but the processing methods differ and result in distinct end products.
Key Steps in Producing Hydrolyzed Collagen
- Sourcing: Raw materials, such as bovine hides, fish scales, or chicken cartilage, are sourced from animal by-products.
- Denaturation: The native collagen is first treated with heat or chemicals to break its triple-helix structure into individual protein chains.
- Hydrolysis: Proteolytic enzymes are used to further break down the protein chains into smaller, low-molecular-weight peptides. This carefully controlled process is what creates the highly absorbable peptides.
- Purification and Drying: The resulting peptides are then purified and dried, often into a fine powder that dissolves easily in liquids.
Comparison Table: Hydrolyzed Collagen vs. Gelatin
| Feature | Hydrolyzed Collagen (Collagen Peptides) | Gelatin | 
|---|---|---|
| Processing | Fully hydrolyzed, broken down with enzymes or acids | Partially hydrolyzed, broken down with heat | 
| Molecular Weight | Low (3–6 kDa), making it highly bioavailable | High, comprising longer amino acid chains | 
| Solubility | Dissolves easily in both hot and cold liquids | Only dissolves completely in hot liquids | 
| Gelling Property | No, does not form a gel | Yes, forms a gel when cooled | 
| Common Use | Nutritional supplement (powder, capsules) | Gelling agent in cooking, candies, and desserts | 
| Absorption | Very high, rapidly absorbed in the small intestine | Digestible, but less efficiently absorbed than peptides | 
Bioavailability and Health Benefits
The reason for the emphasis on the “hydrolyzed” nature of this supplement is its improved bioavailability. Because the peptide chains are small, they are more easily digested, absorbed into the bloodstream, and transported to the body's tissues. This makes hydrolyzed collagen effective for several health and beauty applications.
Key benefits include:
- Skin Health: Studies have shown that supplementing with hydrolyzed collagen can improve skin hydration, elasticity, and firmness while helping to reduce the appearance of wrinkles.
- Joint and Bone Support: Collagen is a critical component of cartilage and bone. Supplementation can help relieve joint pain associated with osteoarthritis and support overall bone health and density.
- Muscle Mass: It may also aid in building and preserving lean muscle mass, especially when combined with resistance training.
- Hair and Nail Strength: Consuming hydrolyzed collagen can contribute to healthier hair and stronger nails.
Factors to Consider When Choosing a Supplement
When purchasing a hydrolyzed collagen supplement, several factors can influence the product's quality and effectiveness:
- Source: Look for products derived from high-quality sources, such as grass-fed bovine or wild-caught marine sources. Marine collagen, for example, is often rich in type I collagen, which is excellent for skin health.
- Third-Party Testing: Since supplements are not strictly regulated, choosing a brand that undergoes third-party testing for purity and safety is advisable.
- Additional Ingredients: Many supplements include complementary ingredients like Vitamin C, which is essential for the body's own collagen synthesis.
Conclusion
The terms hydrolyzed collagen, collagen peptides, and collagen hydrolysate all refer to the same type of protein supplement—one that has been broken down for superior absorption and effectiveness. While the names may differ based on whether they describe the process (hydrolyzed collagen/collagen hydrolysate) or the result (collagen peptides), they all point to a product designed to provide maximum benefit to the user. By understanding the distinction between this highly bioavailable form and other collagen-derived products like gelatin, consumers can make informed decisions to support their skin, joint, and bone health. Ultimately, the focus should be on the bioactive peptides and the quality of their source, ensuring the supplement provides the intended health-boosting properties.
