    Bone broth and the gut: what research can tell us

    Bone broth is a savory liquid made by simmering animal bones and connective tissue. It provides protein and amino acids, including glycine and, in variable amounts, glutamine. It can be a useful food or cooking ingredient, but claims that it repairs the gut lining or treats “leaky gut” go beyond the available evidence. Research on individual nutrients does not prove that drinking bone broth improves intestinal permeability in people.

    What is the intestinal mucosa?

    The intestinal mucosa is the inner lining of the digestive tract. It includes a surface layer of cells, mucus, immune components and other structures that help absorb nutrients while forming a selective barrier. The cells are joined by proteins called tight junctions, which help regulate movement between them. Barrier function can change for many reasons, but a symptom or commercial test alone cannot establish a specific “leaky gut” diagnosis.

    The digestive system breaks down food, absorbs nutrients and water, and interacts with the immune system and gut microbiome. Supporting general digestive health involves more than one food or supplement; the evidence for bone broth as a specific gut-barrier intervention remains limited.

    Evidence for bone broth and intestinal permeability

    There is not strong clinical evidence that bone broth itself improves intestinal permeability, heals the gut mucosa or treats a digestive condition. The proposed benefits are based mainly on the nutritional properties of its ingredients and on research into individual compounds—not on well-established human trials of bone broth for “leaky gut.”

    Collagen peptides and gelatin

    Cooking connective tissue can release gelatin, and collagen proteins are broken down during digestion into peptides and amino acids. This makes them a source of dietary protein, but it does not demonstrate that gelatin or collagen peptides reach the intestinal lining and repair it. Direct evidence that collagen from bone broth strengthens tight junctions in people is insufficient.

    Glutamine

    Glutamine is used by intestinal cells and has been studied as a nutrient in clinical settings. That research does not establish that the amount in a serving of bone broth has the same effect as a studied supplement or improves gut-barrier outcomes. Bone broth’s glutamine content can vary with ingredients and preparation.

    Glycine and other amino acids

    Glycine and other amino acids have biological roles in the body, and some laboratory or animal research examines their effects on inflammation and tissue function. Such findings do not show that drinking bone broth reduces intestinal inflammation or improves symptoms in people. Claims about a food’s clinical effects require human studies of that food and outcome.

    Bone broth compared with other approaches

    Bone broth can contribute fluid and protein, but it is not a proven substitute for medical care, a varied diet or a treatment recommended for a diagnosed condition. L-glutamine supplements provide a different, more concentrated amount of a single amino acid; evidence about a supplement cannot automatically be applied to broth. The right approach depends on the health concern, and supplements should be discussed with a healthcare professional when relevant.

    Overall, the main evidence limitation is the lack of robust human trials directly testing bone broth for intestinal permeability, tight-junction function or gut symptoms. Research on ingredients, cell models or animals can suggest hypotheses, but it cannot confirm that broth produces those outcomes in people.

    How to Reduce Gut Inflammation: Foods and Easy Recipes

    Bone broth, inflammation and the gut microbiome

    Bone broth contains nutrients that are part of a normal diet, but it has not been shown to prevent or treat chronic inflammation, autoimmune disease or microbiome dysbiosis. Dysbiosis is a broad term for an altered microbial community; its meaning and relevance depend on context, and it is not a diagnosis that can be determined from symptoms alone.

    Inflammation is part of the body’s immune response. Chronic inflammation can have many causes, and an anti-inflammatory food claim should not be taken to mean that one food can resolve it. Bone broth may fit into a balanced eating pattern, but there is not sufficient evidence to describe it as an anti-inflammatory treatment or as a way to change the gut microbiome in a predictable, beneficial way.

    Practical foundations for digestive health

    No single “gut reset” or food works for everyone. General habits that may support digestive health include eating a varied diet with fiber-rich foods as tolerated, drinking enough fluids, being physically active, getting adequate sleep and managing stress. Changes should be tailored to individual needs, especially for people with a diagnosed digestive condition or dietary restrictions.

    Digestive symptoms can include abdominal pain, bloating, changes in bowel habits, diarrhea or constipation. These symptoms have many possible causes and do not, by themselves, identify an unhealthy gut or a particular microbiome problem. Seek medical advice for persistent or worsening symptoms, blood in stool, unexplained weight loss, severe pain or other concerning changes.

    Supporting regular gut motility

    Regular movement, adequate fluids and dietary fiber may support bowel regularity for many people, but the right amount of fiber and fluid varies. Increase fiber gradually if appropriate, since a sudden increase can worsen gas or discomfort. Persistent constipation or a sudden change in bowel habits warrants discussion with a healthcare professional.

    Choosing and preparing bone broth

    Bone broth is made by simmering bones and connective tissue in water, sometimes with vegetables and seasonings. Chicken broth is generally made by simmering chicken meat, bones or both; stock traditionally uses more bones and connective tissue and may be simmered longer. In everyday cooking, the terms broth and stock are often used interchangeably, and products vary, so check the ingredient list and nutrition label.

    A clear, strained broth may look like a clear liquid, but bone broth is not automatically suitable before a medical procedure. It can contain protein, fat, particles or ingredients that do not meet the instructions for a clear-liquid diet. Follow the specific guidance from your healthcare team rather than relying on the product name or appearance.

    Making or buying it

    For homemade broth, simmer bones with water and optional vegetables and seasonings, then strain and refrigerate promptly. Follow safe food-handling and storage practices. For packaged broth, compare sodium, ingredients and serving size. Product composition—including protein, sodium and amino acids—can differ considerably, so bone broth is not necessarily more nutritious than every stock or broth.

    Considerations and possible risks

    Some broths are high in sodium, which may matter for people advised to limit sodium. Ingredient sourcing and manufacturing affect product quality; contamination levels can vary, and consumers may look for transparent sourcing and appropriate quality testing. People who are sensitive to histamine-containing foods may find that certain long-cooked or stored broths trigger symptoms, although individual responses vary. Stop consuming a food that causes a reaction and seek professional guidance if symptoms are concerning.

    Bone broth is a food, not a treatment. People with allergies, medical conditions, prescribed diets or ongoing digestive symptoms should ask a qualified healthcare professional whether it fits their needs.

    How to include bone broth in your diet

    Use bone broth as a warm drink, soup base or cooking liquid for grains and vegetables. There is no established daily amount needed for gut health, and no evidence-based serving that repairs intestinal permeability. Choose an amount that fits your preferences and dietary needs, and account for the sodium and protein listed on the label.

    For a broader approach to gut health, build meals around a variety of foods you tolerate, including vegetables, fruit, legumes, whole grains, nuts or seeds where appropriate. Bone broth can be one option within that pattern, not a replacement for dietary variety or individualized medical care.

    Common questions

    #### How much bone broth should you drink?

    There is no official recommended daily intake for bone broth and no proven dose for gut benefits. Serving sizes vary by product; use the label and your dietary needs as a guide.

    #### Is chicken broth hydrating, and is it good for you?

    Chicken broth contributes fluid and may also provide protein and sodium, depending on the product. Whether it is a good choice depends on its ingredients, nutritional content and how it fits your overall diet.

    #### Is it good to drink bone broth in the morning?

    You can drink it in the morning if you enjoy it, but there is no established evidence that morning consumption provides special gut benefits.

    #### Can bone broth get rid of inflammation in the gut?

    There is no good evidence that bone broth treats intestinal inflammation. Persistent digestive symptoms or suspected inflammation should be assessed by a healthcare professional.

    Bone broth can be a convenient, savory source of fluid and nutrients. However, current evidence does not show that it heals the gut lining, changes intestinal permeability or treats inflammation. Treat it as a food you may enjoy—not as a proven gut-health remedy.
