The Nutritional Profile of Bone Marrow
Bone marrow, the soft, spongy tissue found in the center of bones, is primarily composed of fat, with smaller amounts of protein, vitamins, and minerals. While its macronutrient profile is predominantly fat, it contains several noteworthy compounds that contribute to its celebrated health reputation. A single tablespoon of raw caribou bone marrow contains a significant amount of calories and fat, alongside trace amounts of B vitamins and minerals like iron.
Rich in Healthy Fats
Contrary to outdated health advice, not all fats are created equal. Bone marrow is rich in specific types of healthy fats, including monounsaturated fats like oleic acid (also found in olive oil) and beneficial saturated fats like stearic acid. It also contains conjugated linoleic acid (CLA), a fat known for its potential anti-inflammatory properties and ability to enhance immune function.
A Source of Collagen and Other Compounds
Bone marrow is a significant source of collagen, the most abundant protein in the body, which plays a crucial role in maintaining healthy skin, bones, and joints. Additionally, it contains glycosaminoglycans like glucosamine and chondroitin, which are frequently used as supplements to support cartilage and joint health.
Contains a Variety of Micronutrients
While not a powerhouse of every single vitamin and mineral, bone marrow contributes to your daily intake of several important micronutrients. These include B vitamins (such as B12 and riboflavin), vitamin A, vitamin E, iron, and phosphorus. It also contains adiponectin, a protein hormone involved in regulating inflammation and immune function.
Potential Health Benefits of Consuming Bone Marrow
Several compounds found in bone marrow have been associated with positive health outcomes, though research on the direct consumption of bone marrow is more limited compared to studies on its individual components.
- Supports Joint Health: The combination of collagen, glucosamine, and chondroitin may help maintain cartilage integrity, reduce joint pain, and improve mobility, particularly in conditions like osteoarthritis.
- Fights Inflammation: Glycine and conjugated linoleic acid (CLA) found in bone marrow have demonstrated anti-inflammatory properties in studies, which could help combat chronic inflammation linked to various diseases.
- Promotes Skin Health: Collagen is a major component of healthy skin. The collagen in bone marrow could help improve skin elasticity and hydration, protecting against signs of aging.
- Aids Gut Health: Bone broth, made by simmering bones, is known to support the gut lining due to its gelatin content, and the marrow contributes to this effect by providing nutrients that help repair the intestinal barrier.
- Boosts Immune Function: Bone marrow contains stem cells that are crucial for producing white blood cells, which are the body’s primary defense against infection. The nutrients in marrow support this cellular factory.
Potential Risks and Considerations
Despite its benefits, consuming bone marrow comes with a few important considerations.
- High Fat and Cholesterol: Bone marrow is very high in fat and calories. Individuals with concerns about high cholesterol or those on a low-fat diet should consume it in moderation.
- Source Matters: Environmental toxins, including heavy metals like lead, can accumulate in animal fat and bones. It is crucial to source bone marrow from high-quality, grass-fed, and humanely raised animals to minimize the risk of contaminants.
- Purine Content: Bone marrow contains purines, which can increase uric acid levels in the body. This is a concern for individuals with gout or other related conditions.
How to Incorporate Bone Marrow into Your Diet
Bone marrow is a versatile ingredient that can be enjoyed in several delicious ways:
- Roasted: A popular method is to roast split marrow bones until the marrow is soft and buttery. The cooked marrow can be scooped out and spread on toast with a sprinkle of salt.
- In Broth: Simmering marrow bones with vegetables and herbs for an extended period creates a rich and flavorful bone broth, which can be sipped on its own or used as a base for soups and sauces.
- As a Spread: Roasted marrow can be blended with butter and herbs to create a savory compound butter, perfect for melting over steak or grilled vegetables.

Conclusion: A Nutritious Addition, In Moderation
In conclusion, the question of whether is bone marrow good for you has a complex answer. It is a highly nutritious food, offering a rich source of healthy fats, collagen, and compounds beneficial for joint health, skin, and immune function. However, its very high fat and calorie content means it should be consumed in moderation as part of a balanced diet. Prudent sourcing from healthy, grass-fed animals is also critical to minimize risks of contaminants. For those interested in incorporating it, delicious preparations like roasting or making nutrient-rich bone broth are excellent options.
