How Collagen Is Made: From Raw Material to Supplement

Collagen supplements have become a cornerstone of the wellness and beauty industries, but how exactly are they made? The process involves careful sourcing, extraction, and purification to ensure the highest quality. In this blog post, we’ll break down how collagen is manufactured, step by step.


Step 1: Sourcing Collagen

Collagen is derived from animal byproducts, as it’s found in connective tissues, skin, and bones. The primary sources include:

  • Bovine Collagen (Cow): Taken from the hides and bones of grass-fed cattle.
  • Marine Collagen (Fish): Extracted from fish scales, skin, or bones.
  • Porcine Collagen (Pig): Sourced from pig skin.
  • Chicken Collagen: Found in chicken cartilage, skin, and bones.

Sustainability and ethical sourcing are crucial, especially for products targeting health-conscious consumers. High-quality collagen brands often source their materials from grass-fed, pasture-raised, or wild-caught animals.


Step 2: Cleaning and Preparing Raw Materials

The raw materials (hides, bones, or fish scales) are thoroughly cleaned to remove impurities such as fat and hair. This step is crucial to ensuring the final product is safe and free from contaminants.


Step 3: Extraction

The collagen is extracted from the raw materials using heat and water in a process called hydrolysis. Here’s how it works:

  • Boiling: The materials are simmered to break down the collagen fibers into gelatin. This step mimics traditional bone broth preparation but is conducted on a larger, more controlled scale.
  • Hydrolysis: The gelatin is subjected to enzymes that further break down the collagen into smaller peptides or amino acids, making it highly bioavailable (easier for the body to absorb). The result is hydrolyzed collagen, also known as collagen peptides.

Step 4: Filtration and Purification

After extraction, the liquid collagen undergoes several rounds of filtration to remove unwanted particles, impurities, or odors. This ensures the collagen is clean and suitable for consumption. For marine collagen, this step is particularly important to eliminate the fishy smell and taste.


Step 5: Drying and Powdering

The purified collagen liquid is dried into a fine powder using a process called spray drying. In this method:

  • The liquid collagen is sprayed into a heated chamber where the water evaporates.
  • The result is a lightweight, shelf-stable powder that can be easily packaged and stored.

Some manufacturers may further process the collagen into capsules, tablets, or flavored mixes, depending on the product type.


Step 6: Quality Control

Each batch of collagen undergoes rigorous quality control testing to ensure:

  • It’s free of harmful pathogens, heavy metals, or allergens.
  • It meets regulatory standards for safety and efficacy.
  • Its amino acid profile aligns with the expected nutritional benefits.

Optional: Adding Functional Ingredients

Many collagen products are enhanced with additional nutrients for improved benefits. For example:

  • Vitamin C: Boosts collagen synthesis in the body.
  • Hyaluronic Acid: Supports skin hydration.
  • Flavors or Sweeteners: Improves taste for easy consumption.

Sustainability and Ethical Concerns

Collagen production has faced scrutiny for its environmental impact. To address this, many companies now:

  • Source materials from byproducts of the meat and fishing industries to minimize waste.
  • Use sustainable fishing practices for marine collagen.
  • Emphasize transparency in sourcing and manufacturing processes.

Final Packaging

The finished collagen is packaged into jars, pouches, or capsules and labeled with instructions for use. Brands targeting the premium market often focus on sleek, eco-friendly packaging to appeal to environmentally conscious consumers.


Key Takeaways

Collagen production is a meticulous process that transforms animal byproducts into a highly refined and beneficial supplement. Understanding how collagen is made can help consumers make informed decisions about the products they choose.
