When looking at collagen product labels, you’ll often see terms like “hydrolysate,” “collagen peptides,” or “gelatin.” These indicate the form in which collagen has been processed and used in the product. But what exactly do these terms mean? How do they differ? And how can you use this information to better interpret labels? This article offers a clear, factual explanation.
What Is Collagen?
Collagen is a structural protein naturally found in connective tissue, skin, bones, and cartilage of humans and animals. In supplements, collagen is typically sourced from animals such as bovine, fish (marine), pork, or chicken. It is then processed into a usable form for application in capsules, powders, or liquid products.
Why Are There Different Forms of Collagen in Products?
Raw collagen from animal tissue is not directly soluble or suitable for consumption. It must be processed using methods such as heat or enzymatic hydrolysis. These methods result in gelatin, collagen hydrolysate, or collagen peptides. Each form has different solubility, structure, and applications.
1. Gelatin – Partially Hydrolyzed Collagen
- What is it? Gelatin is created by heating collagen in water, which partially breaks down the protein chains. This process results in a gel-like substance when cooled.
- Properties: Gelatin dissolves only in warm water and forms a jelly-like texture. It’s widely used in food products (such as desserts or gummies) and in supplements like capsules or softgels.
- Labeling: Usually listed as “gelatin,” “collagen (gelatin form),” or “bovine/marine/pork gelatin.”
2. Collagen Hydrolysate – Fully Hydrolyzed Collagen
- What is it? Collagen hydrolysate is collagen that has been fully broken down through enzymatic hydrolysis into smaller amino acid chains called peptides.
- Properties: This form is soluble in both hot and cold water, is usually neutral in taste and smell, and is commonly used in powders or drinks.
- Labeling: Often listed as “collagen hydrolysate,” “hydrolyzed collagen,” or “collagen peptides.”
3. Collagen Peptides – Another Name for Hydrolysate
- What is it? The terms “collagen peptides” and “collagen hydrolysate” are used interchangeably. Both refer to the same substance: fully hydrolyzed collagen broken down into short peptide chains.
- Properties: Identical to hydrolysate in solubility and structure. The term used may vary by brand or region.
- Labeling: Look for “bioactive collagen peptides,” “hydrolyzed peptides,” or simply “peptides.”
Overview of the Differences
| Form | Process | Solubility | Labeling |
|---|---|---|---|
| Gelatin | Partially hydrolyzed (heat) | Only in warm water | Gelatin, collagen (gelatin) |
| Hydrolysate | Fully hydrolyzed (enzymatic) | In cold and warm water | Collagen hydrolysate, collagen peptides |
| Peptides | Synonym for hydrolysate | In cold and warm water | Collagen peptides |
How Do These Forms Differ in Use?
The form in which collagen is processed influences how it can be used:
- Gelatin: Commonly used in capsules, softgels, and edible products like gummies. Due to its gelling properties, it’s less suitable for powder-based supplements.
- Hydrolysate/peptides: Ideal for powders, stick packs, liquid shots, and dissolvable drinks. Soluble in water and easy to mix.
Are There Quality Differences Between the Forms?
The form describes the processing method, but not necessarily the quality of the collagen. Quality can be influenced by factors such as purity, source (e.g. bovine or marine), and the presence of additives or flavorings. This information is usually listed separately on the label.
International Use of Terminology
In English-speaking markets, the terms “hydrolyzed collagen” or “collagen peptides” are common. In German, you may see “Kollagenhydrolysat.” While names vary, the substance is the same: hydrolyzed collagen.
Common Misconceptions
Some product descriptions and websites may include unclear or misleading information. For example:
- “Peptides are better than hydrolysate” – This is misleading; they refer to the same substance.
- “Gelatin is pure collagen” – Gelatin is a processed form of collagen with different structure and solubility.
- “Hydrolysate is 100% active” – Such claims are not allowed under food labeling regulations. Only factual product information may be stated.
What Can You Learn From the Label?
A collagen label may state which form is used (gelatin or hydrolysate), the source (e.g. marine, bovine), and how much is included per serving. Transparent brands also include information on allergens such as fish or beef, and relevant certifications like Non-GMO or halal.
Summary
- Collagen comes in three main forms: gelatin, hydrolysate, and peptides.
- Gelatin is heat-treated and dissolves only in warm water.
- Hydrolysate (collagen peptides) is enzymatically processed and dissolves in both cold and warm water.
- “Peptides” and “hydrolysate” refer to the same substance.
- Always read the label to determine the form, source, and dosage per serving.
Frequently Asked Questions
1. What’s the difference between peptides and hydrolysate?
None. Both terms refer to fully hydrolyzed collagen in peptide form.
2. Is gelatin less suitable than peptides?
Not necessarily. It depends on how you want to use it. Gelatin is useful in capsules and edible forms like gummies, while hydrolysate is ideal for dissolving in drinks.
3. What should I look for when choosing a collagen product?
Check the form (gelatin or hydrolysate), source (bovine, fish, chicken), collagen content per serving, potential allergens, and optional certifications like Non-GMO or halal.
