The macronutrient composition of bone broth is not a one-size-fits-all answer. Several factors influence the final values, but it's universally known for its high protein content and low carbohydrate count. Examining the common varieties like chicken and beef broth reveals important distinctions for those mindful of their nutritional intake. The primary nutrient is protein, which is largely derived from the collagen extracted from the bones and connective tissues during the long simmering process.
Chicken vs. Beef Bone Broth Macros (2 Cups)
The macros for 2 cups of bone broth can differ significantly depending on the animal source. A chicken bone broth often has a slightly different balance of protein and fat compared to beef, influenced by the types of bones and cartilage used.
Chicken Bone Broth (2 Cups)
Based on common commercial brands and typical homemade recipes, 2 cups of chicken bone broth can offer a substantial protein boost. A low-sodium, low-fat option from a brand like Pacific yields approximately 18g of protein, 2g of carbohydrates, and 1g of fat per 2-cup serving. This high protein-to-calorie ratio makes it an excellent choice for satiety and muscle support without adding excess calories. The carbohydrate content comes from any added vegetables used during simmering, while the fat is minimal, especially if skimmed off after cooking.
Beef Bone Broth (2 Cups)
Beef bone broth, especially when made from marrow bones, can be slightly richer. The protein content is often comparable to or slightly higher than chicken broth, with a potentially higher fat content depending on how it's prepared. For example, a 2-cup serving of beef bone broth might contain around 14-20g of protein, 1-4g of carbs, and 0-2g of fat. Variations in preparation, particularly how much fat is skimmed, will significantly alter the final fat content.
Homemade vs. Store-Bought Nutrition
The most significant variance in the macros for 2 cups of bone broth comes from comparing homemade preparations with store-bought products. Homemade versions offer complete control over ingredients, while store-bought varieties offer convenience but with potential trade-offs in sodium and filler ingredients.
Homemade Control
- Customizable Macros: When you make bone broth at home, you dictate the macros. You can control the protein content by using more collagen-rich bones like chicken feet or marrow bones.
- Fat Control: You can easily increase or decrease fat content. For low-fat needs, chilling the broth allows you to skim off the solidified fat cap before reheating.
- Sodium Management: A major advantage of homemade broth is controlling sodium levels, avoiding the high concentrations often found in processed store-bought options.
Store-Bought Considerations
- Ingredient Transparency: Not all products labeled "bone broth" are created equal. Some may be watered down or use filler proteins to increase the protein count.
- Added Ingredients: Many commercial broths contain flavor enhancers like MSG, added yeast extracts, and high levels of sodium, which can alter the macro profile.
- Gelling Factor: The level of "gel" in a refrigerated bone broth is an indicator of collagen content. While some store-bought brands gel, they may be less concentrated than a high-quality homemade version.
Comparison Table: Homemade vs. Store-Bought Bone Broth (2 Cups)
| Feature | Homemade Bone Broth | Store-Bought Bone Broth (e.g., Pacific Chicken) |
|---|---|---|
| Protein (approx.) | 18-28g | 18g |
| Carbs (approx.) | 2-10g (depending on vegetables) | 2g |
| Fat (approx.) | 1-5g (adjustable) | 1g |
| Sodium | Fully customizable | 190mg (for low-sodium option) |
| Cost | More cost-effective for large batches | Higher per serving |
| Nutrient Density | Often higher in collagen and minerals | Varies significantly by brand and quality |
| Control | Full control over all ingredients | Limited to what's listed on the label |
Conclusion
In summary, understanding the macros for 2 cups of bone broth reveals that it is primarily a lean protein source with negligible carbohydrates. While homemade offers superior control over ingredients and nutrition, high-quality store-bought brands can still be a convenient and healthy option. The key is to prioritize protein content and minimize added salt and fillers, aligning with your dietary goals. For those seeking maximum collagen benefits and control, the time invested in making your own is worthwhile. For quick protein fuel, selecting a low-sodium commercial option is a smart choice.

Factors Influencing Your Broth's Macros
Several variables determine the final macro count in your bone broth batch. Recognizing these helps you fine-tune your recipe or make informed purchasing decisions.
- Bone Selection: The type of bones used is critical. Bones with more connective tissue and cartilage, like knuckles or chicken feet, will produce a broth with a higher protein and gelatin content. Marrow bones, while excellent for flavor, can introduce more fat if not removed.
- Cooking Time: Simmering for longer periods (12-24 hours) extracts more minerals, collagen, and amino acids from the bones, resulting in a denser, more nutrient-rich broth. Shorter cooking times will yield a less concentrated liquid.
- Added Ingredients: Incorporating vegetables (onions, carrots, celery) can increase the carbohydrate count slightly. Adding herbs and spices will not significantly alter the macros but can enhance flavor and nutrient profile.
- Fat Removal: The amount of fat skimmed from the top after cooling dramatically affects the final fat and calorie content. For a lower-fat broth, removing all solidified fat is essential.
Recipe for a High-Protein Homemade Bone Broth
Making your own bone broth is a straightforward process that allows for total macro control. Here is a simple recipe to maximize protein and minimize carbs.
Ingredients:
- 4 lbs bones (a mix of knuckles and marrow for beef; feet and frames for chicken)
- 1 large onion, quartered
- 2 carrots, roughly chopped
- 2 celery stalks, roughly chopped
- 2 tbsp apple cider vinegar (helps pull minerals from bones)
- 1 tsp black peppercorns
- A few sprigs of fresh parsley and thyme
- Water to cover
Instructions:
- Roast Bones: Preheat oven to 400°F (200°C). Arrange bones on a baking sheet and roast for 30 minutes until browned. This enhances the flavor.
- Combine Ingredients: Place roasted bones, onion, carrots, celery, and apple cider vinegar into a large stockpot. Cover with water.
- Simmer Slowly: Bring to a boil, then reduce heat to a low simmer. Cook for a minimum of 12 hours, up to 24 hours for maximum extraction. Skim any foam that rises to the top.
- Add Herbs: In the last hour of cooking, add the peppercorns, parsley, and thyme.
- Strain and Store: Remove from heat and strain the broth through a fine-mesh sieve or cheesecloth. Let it cool completely. A gelatinous layer may form, which is a good sign of high collagen content. Scrape off the solidified fat cap if desired.
- Enjoy or Freeze: Store the broth in the refrigerator for up to a week, or freeze it in smaller portions for long-term use.
