According to research, the body's natural collagen production begins to decline in the mid-20s, making it a popular supplement for supporting skin, joint, and overall vitality. However, you can learn how to prepare collagen at home, bypassing expensive store-bought products and ensuring a high-quality, whole-food source for your nutritional needs.

Quick Summary

Creating homemade collagen involves a slow-simmering process with animal bones or connective tissues. This method extracts gelatin, the cooked form of collagen, into a nutrient-rich and versatile broth. The resulting product is excellent for adding to soups, stews, or for making homemade gummies.

Key Points

Start with Quality Ingredients: Use bones and connective tissues from pasture-raised or organic animals to ensure a high-quality, nutrient-rich base for your homemade collagen.
Simmer Low and Slow: A long, gentle simmer (12-24+ hours) is essential for effectively extracting the collagen from the bones. The key is to keep the liquid at a very low bubble.
Add Vinegar: A small amount of apple cider vinegar helps to draw out the minerals and collagen from the bones during the simmering process, enhancing the broth's nutritional value.
Chill to Test Gelatin: A good homemade collagen broth will turn into a thick, jiggly, gelatinous consistency when chilled. This is a sign of a high collagen concentration.
Consider Powder for Convenience: While more effort-intensive, dehydrating your broth into a powder provides a shelf-stable and versatile product for long-term use.
Mind Food Safety: Ensure all ingredients are from clean sources and that proper storage procedures are followed to prevent contamination, especially when making powder.
Support with Vitamin C: Pair your homemade collagen with foods rich in Vitamin C, as this nutrient is a critical cofactor in the body's natural collagen production.

Sourcing Your Ingredients

Starting with the right ingredients is the most critical step for making high-quality homemade collagen. The best sources are animal parts rich in connective tissues, which are packed with this vital protein. For a robust, flavorful, and collagen-dense broth, consider using a variety of bones from healthy, pasture-raised animals.

Beef Bones: Knuckle, neck, and marrow bones are excellent choices, as they contain high amounts of both collagen and nutrients. Roasting the bones first can significantly enhance the flavor of your final product.
Chicken Feet: Often overlooked, chicken feet are a powerhouse of collagen and gelatin, guaranteeing a very rich, jiggly, and bouncy broth when properly simmered.
Fish Carcasses: Fish frames, including the heads and skin, can be used for a marine-based collagen broth, rich in beneficial fatty acids. Always ensure the fish is from a clean, reliable source to avoid heavy metal contamination.
Eggshell Membranes: The thin membrane lining the inside of an eggshell is a concentrated source of collagen and other beneficial compounds. This can be added to your broth or dried and ground into a powder.

How to Make Collagen-Rich Bone Broth

This is the most popular and effective method for creating a readily usable form of homemade collagen. The long, slow simmer breaks down the connective tissues and releases the collagen, which becomes gelatin when cooled.

Ingredients:

3-4 lbs bones (a mix of beef and chicken is great)
1 large onion, quartered
2 carrots, roughly chopped
2 celery stalks, roughly chopped
2 tbsp apple cider vinegar (helps pull minerals and collagen from bones)
1 tsp black peppercorns
Cold, filtered water

Instructions:

Roast Bones (Optional): For a deeper flavor, roast beef bones on a baking sheet at 400°F (200°C) for 30 minutes until browned. This step is not necessary for chicken bones.
Combine & Soak: Place all bones in a large stockpot or slow cooker. Add the vegetables and cover everything with cold water. Add the apple cider vinegar and let it sit for 30 minutes to an hour before heating.
Bring to a Simmer: Bring the pot to a boil, then immediately reduce the heat to a low simmer. The mixture should just gently bubble.
Simmer for an Extended Period: Simmer, partially covered, for at least 12-24 hours for beef bones, or 6-12 hours for chicken feet. The longer you simmer, the more nutrients and collagen you will extract.
Skim the Scum: As it simmers, use a spoon to periodically skim off any foam or impurities that rise to the surface.
Strain: Once the broth is complete, remove from heat and strain through a fine-mesh sieve or cheesecloth to separate the liquid from the solids.
Chill: Allow the liquid to cool completely, then refrigerate overnight. A thick, gelatinous layer should form. A solidified top layer of fat can be scraped off and discarded or saved for cooking.

Homemade Collagen Powder

For a more shelf-stable and versatile product, you can dehydrate your finished bone broth into a powder, similar to commercially available collagen peptides.

Reduce Broth: After refrigerating and removing the fat layer, reduce the strained, gelatinous broth in a pot over low heat. Simmer until the liquid is very thick and dark, which will concentrate the collagen.
Dehydrate: Pour the thick liquid onto a dehydrator tray or a silicone baking mat on a sheet pan. Dry it at a very low temperature (around 140°F / 60°C) for several hours until it becomes completely dry and brittle, like a hard candy sheet.
Grind: Break the dried sheet into smaller pieces and grind them into a fine powder using a high-powered blender or coffee grinder.
Store: Keep the powder in an airtight container in a cool, dry place.

Other DIY Collagen Boosters

While true collagen comes from animal sources, you can also support your body's natural collagen production with certain plant-based nutrients and recipes.

Vitamin C Boosters: Vitamin C is essential for collagen synthesis. Try blending citrus juice, strawberries, and other vitamin C-rich fruits into a smoothie or drink to support your body's natural collagen formation.
Herbal Powder: Some recipes suggest blending plant-based ingredients like amla (Indian gooseberry), moringa, and seeds to create a powder. While not a direct source of collagen, these ingredients provide vitamins and antioxidants that aid in its production.
