The Core Nutrients in 1 Cup of Bone Broth
The nutritional value of a single cup of bone broth can vary dramatically based on the type of bones used, the cooking time, and the concentration. High-quality, long-simmered bone broth is typically rich in specific nutrients that are extracted from the bones, connective tissues, and marrow.
Protein and Collagen
Protein is one of the most prominent macronutrients in bone broth, with commercial and homemade versions often containing anywhere from 8 to 20 grams per cup, especially in concentrated formulas. Much of this protein is in the form of gelatin, which is the cooked form of collagen. Gelatin is responsible for the signature jelly-like consistency of chilled, high-quality bone broth and is easily digestible. Collagen, the most abundant protein in the body, is vital for the health of skin, joints, tendons, and bones.
Amino Acids
During the simmering process, the collagen in the bones breaks down into amino acids, which are the building blocks of protein. A cup of bone broth delivers a unique profile of these amino acids, many of which are beneficial for different bodily functions. Some of the most notable amino acids found include:
- Glycine: Supports sleep quality and helps regulate the central nervous system.
- Proline: Important for the structural integrity of skin, bones, and cartilage.
- Arginine: Plays a role in immune system function and wound healing.
- Glutamine: A key nutrient for cells lining the gut, helping to maintain a healthy intestinal wall.
Minerals and Electrolytes
Contrary to some popular claims, bone broth is not a potent source of high levels of vitamins or minerals like calcium. The long simmering process does, however, pull some minerals from the bones into the liquid, contributing to its electrolyte profile. A cup of bone broth can provide small amounts of:
- Potassium: An essential electrolyte for fluid balance and muscle function.
- Sodium: Necessary for proper hydration, though levels can vary significantly in commercial products.
- Magnesium: Involved in hundreds of bodily processes, including nerve and muscle function.
- Calcium and Phosphorus: Present in trace amounts, these minerals support bone health.
Calories, Fat, and Carbs
For most high-quality bone broths, the caloric count is low, generally ranging from 30 to 120 calories per cup, depending on the fat content. A cup typically contains low to zero carbohydrates, making it suitable for low-carb and ketogenic diets. The fat content is also usually low, especially if the fat is skimmed off after cooling, though some beef broths may have slightly more.
Comparison: Beef vs. Chicken Bone Broth
The nutritional breakdown can differ based on the animal source. Below is a comparison of typical characteristics for high-quality, long-simmered beef and chicken bone broths.
| Aspect | Beef Bone Broth | Chicken Bone Broth |
|---|---|---|
| Primary Collagen Types | Type I and Type III | Type II |
| Best For | Gut health, skin elasticity, sleep, and energy levels | Joint health, cartilage support, and immune function |
| Amino Acid Profile | Higher in glycine and proline | Higher in branched-chain amino acids (BCAAs) like leucine |
| Electrolyte Content | Often contains a balanced profile | May contain higher levels of potassium and chloride |
| Typical Flavor | Richer, bolder, and more robust | Lighter, milder, and more versatile |
| Simmer Time | Generally requires longer simmering (up to 48 hours) | Shorter simmering time (12-24 hours) |
Homemade vs. Commercial Bone Broth
The most significant factor influencing a cup of bone broth's nutritional value is whether it is homemade or store-bought. Homemade versions allow for complete control over ingredients, bones, simmer time, and seasoning, resulting in a nutrient-dense and preservative-free product. Store-bought varieties, while convenient, often contain higher sodium levels and sometimes use additives or flavor extracts. To maximize nutrient extraction, homemade preparation with a splash of apple cider vinegar and a long simmer is recommended. Look for commercial brands that prioritize long simmering times, use high-quality animal bones, and specify their protein content.
Potential Health Benefits
The nutrients found in bone broth have been linked to several potential health benefits, although more scientific research in humans is needed. These include:
- Joint Support: Glucosamine and chondroitin, found in bone broth, are compounds commonly sold as supplements to aid in joint health and reduce inflammation.
- Gut Health: Amino acids like glutamine and glycine can help strengthen and repair the gut lining, potentially assisting with conditions like "leaky gut" syndrome.
- Improved Sleep: The amino acid glycine has been shown in some studies to improve sleep quality and promote relaxation.
- Skin, Hair, and Nail Health: While collagen itself is broken down during digestion, the resulting amino acids can support the body's natural collagen production, contributing to healthy skin, hair, and nails.

Conclusion
The nutritional value of 1 cup of bone broth is multi-faceted, offering more than just calories and protein. It is a concentrated source of specific, easily digestible nutrients—primarily protein in the form of collagen/gelatin, and a variety of amino acids. It also provides a valuable electrolyte profile, though its vitamin and mineral content should not be mistaken for that of whole foods. The nutritional profile varies by animal source, with beef offering more Type I and III collagen for skin and gut health, and chicken providing more Type II for joint support. For maximum benefit and control over ingredients, homemade is often the superior choice. Incorporating a cup of bone broth into your daily routine can be a simple, flavorful way to support overall wellness, from digestive and joint health to better sleep.
