What is Collagen Soup? How is it Prepared?
Collagen soup, This is a general term used to describe soups prepared with animal ingredients naturally rich in collagen, such as bone broth, or those with hydrolyzed collagen added to the formula. However, not every product has the same ingredients and collagen content. Therefore, it's necessary to look not only at the product name but also at the ingredients list and nutritional information table.
Collagen-enriched soup can be consumed as a convenient ready-to-eat meal, or it can be prepared at home using bone broth instead of the broth from lentil, vegetable, or tarhana soups. The important thing here is to evaluate the product based on its flavor, ingredients, and overall nutritional value, rather than viewing it as a medicine or treatment.
What is collagen soup?
The term "collagen soup" can describe two different types of products. The first group includes soups that use bone broth, prepared by simmering bones and connective tissues for an extended period. The second group includes soups or soup bases to which collagen hydrolysate is added.
This distinction is important because the natural composition of bone broth is not the same as hydrolyzed collagen, which is added in specified amounts. The protein and amino acid content of bone broths can vary depending on the type of bone used, the recipe, the cooking time, and the production method. In a product containing added collagen, the name and often the percentage of this ingredient can be found in the ingredients list.
What is the difference between collagen, gelatin, and hydrolyzed collagen?
- Collagen: It is a structural protein found in connective tissues such as skin, bone, tendons, and cartilage in humans and animals.
- Gelatine: It is a protein structure formed when collagen undergoes a structural change due to heat and water, and it can become thicker when cooled.
- Hydrolyzed collagen: It is a form of collagen protein broken down into smaller peptide fragments and can be added to the formulas of various food products.
Collagen ingested through food is broken down into amino acids and small peptides during digestion. Therefore, it cannot be said that a soup will directly affect a specific area of the body or provide a specific health benefit on its own. Scientific studies yield different results depending on the product's form, quantity, duration of use, and the quality of the research.
What foods contain collagen?
Collagen is naturally found in animal connective tissues. Fish with skin, meats containing connective tissue, and broths made from these meats or bones belong to this group. Gelatin is also derived from collagen. However, the appearance of a food or its jelly-like consistency when cooled does not, by itself, indicate the amount of collagen it contains.
For the body to produce its own collagen, it's not just collagen-rich foods that matter; a balanced diet, including sufficient protein and vitamin C, is essential. Therefore, instead of relying on unmeasured claims like "collagen powerhouse," it's more accurate to check the protein, ingredient, and serving information on product labels.
How to Prepare Collagen Soup?
How do you reheat ready-made collagen soup?
ZEL Collagen-Enriched Anatolian Soup, According to the ingredients list, it is prepared with 15% bone broth and 12% red lentils. The product is ready to eat; it can be transferred from the jar to a pot and heated according to the preparation instructions on the packaging, stirring constantly. Instead of boiling for an unnecessarily long time, heating only the amount to be consumed evenly is more suitable in terms of taste and ease of use.

Homemade collagen soup recipe with bone broth
When making lentil or vegetable soup at home, you can replace part of the water in the recipe with bone broth. For a quick lentil soup serving four, the following method can be used:
- Chop a small onion and a carrot and sauté them briefly in a tablespoon of olive oil.
- Add one cup of washed red lentils to the pot.
- A jar ZEL Bone Broth And depending on the consistency, add about two cups of hot water.
- Cook the lentils and vegetables until tender, then blend them.
- Adjust the salt level last, according to the product label; serve with black pepper, cumin, or mint.
For a more intense bone broth flavor, standard bone marrow broth can be used in this recipe. If you're also looking for an option that includes collagen, try this one which contains 1% collagen hydrolysate. ZEL Collagen-Enriched Premium Bone Broth Similarly, they can be added to the soup's cooking liquid. It's not necessary to use both products together in the same recipe; you can choose one according to your taste and the product label.

Does collagen lose its effectiveness when heated?
Heat can alter the triple helix structure of collagen, causing it to gelatinize. Hydrolyzed collagen, on the other hand, is already broken down into smaller peptides during the production process. Therefore, it is not accurate to say that "all the collagen is destroyed when it goes into hot soup." However, excessive and unnecessarily long boiling can alter the structure and sensory properties of foods. The best practice is to follow the heating instructions on the packaging of ready-made products.
What to Look for on the Label When Choosing Collagen Soup?
- Table of contents: Check if bone broth or collagen hydrolysate is being used and, if so, in what proportions.
- Protein content: Read the nutritional value along with the serving size; products with similar names may have different protein content.
- Salt and portion size: Those who need to limit their salt intake should carefully examine product labels.
- Allergens: Check label warnings regarding wheat, milk, and other allergens.
- Storage and preparation: Follow the storage and heating instructions exactly after opening.

When is bone broth added to the soup?
It can often be added initially as cooking liquid, replacing part of the water in the recipe. If using a ready-made product, the usage instructions on the packaging should take precedence.
