Homemade bone broth has gained immense popularity in recent years for its comforting flavor and touted health benefits, particularly its collagen and protein content. However, unlike commercial products with standardized nutrition labels, the protein in homemade versions can vary significantly. The question of exactly how much protein is in 8 oz of homemade bone broth doesn't have a single answer, but rather a range determined by several key factors.
What Influences the Protein Content?
Several variables in the bone broth-making process directly impact the final protein concentration. These factors explain why one person's homemade broth might be less gelatinous and lower in protein than another's.
The Type of Bones Used
The most significant factor is the quality and type of bones. Bones with high amounts of connective tissue, cartilage, and marrow yield more protein.
- For higher protein: Opt for joints (knuckles), chicken feet, and oxtail, which are rich in collagen.
- For lower protein: Primarily using marrow bones or other meaty bones may result in a less concentrated broth.
The Length of Simmering
A long, slow simmer is crucial for breaking down the collagen in the bones and extracting the amino acids into the liquid.
- A longer cooking time, often 12 to 24 hours for chicken and up to 48 hours for beef, will yield a higher protein concentration.
- Broths simmered for shorter periods will have a much lower protein count, similar to a standard stock.
The Role of an Acid
Adding a small amount of acid, such as apple cider vinegar, helps to draw minerals and collagen from the bones into the water during the simmering process. Without an acidic component, much of the beneficial protein may remain locked within the bone structure, reducing the final protein count.
Homemade vs. Other Broths: A Comparison
The protein content of homemade bone broth stands out when compared to standard broths and commercial alternatives. This table highlights the general differences you can expect.
| Feature | Homemade Bone Broth | Store-Bought Bone Broth | Standard Stock (Homemade) |
|---|---|---|---|
| Protein per 8 oz | 2-14 grams (highly variable) | 8-20+ grams (consistent) | 1-6 grams (low) |
| Gelatin Content | High (often gels when cold) | High (often gels when cold) | Low (does not gel) |
| Ingredients | High-quality bones, vegetables, seasonings | Varies by brand, some add protein powder | Meaty bones, vegetables, shorter simmer |
| Cooking Time | Long (12-48+ hours) | Varies by brand (often concentrated) | Short (1-6 hours) |
| Nutrient Density | High (minerals, amino acids) | Variable (depends on brand standards) | Low (less concentrated) |
| Cost | Typically low (uses scraps) | High (premium product) | Low (uses scraps) |
Maximizing Protein in Your Homemade Bone Broth
To ensure you are getting the most protein and nutrients from your efforts, follow these simple steps:
- Choose the Right Bones: Use a combination of meaty bones, joints, and feet for the highest collagen content.
- Roast Your Bones: Roasting bones before simmering adds a deeper, richer flavor and color to the broth.
- Add an Acid: A tablespoon or two of apple cider vinegar can make a big difference in mineral and collagen extraction.
- Skim the Scum: In the first hour of simmering, a layer of foamy scum will rise to the top. Skimming this off helps create a clearer, cleaner-tasting broth.
- Simmer Low and Slow: A long cooking time on low heat is the most effective way to extract maximum nutrients. A crockpot or slow cooker is ideal for this.
- Reduce the Broth: After straining, you can simmer the broth further to reduce the liquid volume, concentrating the protein and flavor.
Beyond Protein: The Value of Amino Acids
While the total protein count in bone broth is important, the real nutritional value comes from the amino acids released, primarily from collagen. Collagen, the most abundant protein in our bodies, breaks down into amino acids like glycine, proline, and glutamine during the long cooking process.
Lists of potential benefits from these amino acids often include:
- Glycine: Promotes better sleep and has anti-inflammatory properties.
- Proline: An essential component for building connective tissue, skin, and cartilage.
- Glutamine: Helps soothe the digestive system and prevent inflammation.
Even though the body breaks down the collagen into these smaller components, the rich profile of amino acids provides a nutritious boost.

Conclusion: The Final Verdict on Protein
Ultimately, the protein content of 8 oz of homemade bone broth is not a fixed number but a variable range, typically falling between 2 and 10 grams, and sometimes higher with optimal preparation. Your final protein count depends on your choice of bones, cooking duration, and technique. However, regardless of the exact number, homemade bone broth remains a low-calorie source of easily digestible protein and a wide array of beneficial amino acids. While it's not a complete protein source like a piece of meat, it offers a simple, healthy way to supplement your diet with valuable nutrients that support overall health and well-being. For the most protein-dense brew, focus on a high ratio of collagen-rich bones, a long, slow simmer, and a splash of vinegar. The end result is a deeply flavorful, gelatinous liquid that is well worth the effort.
