Drinking bone broth every day is safe for most people and offers a steady supply of amino acids, minerals, and collagen-related compounds that support gut health, joints, skin, and sleep. A typical daily amount is one cup (about 237 ml), though there’s no strict upper limit. The main things to watch are sodium intake from store-bought versions and trace amounts of lead, both of which are manageable with the right choices.
What You Get in a Daily Cup
Bone broth’s nutritional profile comes primarily from collagen that breaks down during long simmering times. The key amino acids are glycine, proline, and hydroxyproline, all building blocks your body uses for connective tissue, gut lining, and skin. Lab analysis of different broths found that chicken bone broth contains roughly 4 mg of glycine and 2.4 mg of proline per gram of broth, with beef and turkey slightly lower. In practical terms, a full cup delivers meaningful amounts of these amino acids, though exact numbers depend heavily on how long the bones were simmered, what type of bones were used, and whether vinegar was added to help extract minerals.
Beyond amino acids, bone broth naturally contains glucosamine and chondroitin (compounds sold separately as joint supplements), hyaluronic acid (a moisture-binding molecule used in skincare), and minerals like calcium, magnesium, and potassium. It also provides glutamine, an amino acid with a specific role in gut health. No single cup delivers massive doses of any one nutrient, but daily consumption adds up over time in ways that occasional use doesn’t.
Gut Health and Intestinal Lining
The glutamine in bone broth is one of its most studied components. This amino acid fuels the cells lining your intestines and helps maintain the tight junctions between them. Those junctions act like seals, controlling what passes from your gut into your bloodstream. When they weaken, bacteria and partially digested food particles can slip through, a condition sometimes called increased intestinal permeability.
Glutamine promotes the growth of new intestinal cells, regulates the proteins that keep tight junctions sealed, and reduces inflammatory signaling in the gut wall. In animal studies, oral glutamine reduced bacterial translocation, the process where gut bacteria cross the intestinal wall and enter surrounding tissue. It also boosted levels of secretory immunoglobulin A, an antibody that coats the gut lining and prevents bacteria from latching onto it. In one human study, glutamine supplementation shifted the balance of gut bacteria in obese individuals, reducing the ratio of two major bacterial groups in a direction associated with better metabolic health.
Drinking bone broth daily provides a low but consistent dose of glutamine alongside the other amino acids that support tissue repair. For people with digestive sensitivity or those recovering from gut-related issues, that consistency matters more than any single large dose.
Joint and Skin Support
Collagen is the most abundant protein in your body, and your natural production of it declines starting in your mid-20s. The collagen in bone broth breaks down during cooking into smaller peptides and amino acids that your body can absorb and use as raw material. Type I collagen supports skin strength and elasticity, while Type III contributes to hydration and firmness.
For joints, the glucosamine and chondroitin extracted from cartilage and connective tissue during simmering are the same compounds found in joint health supplements. They help maintain the cushioning cartilage between bones. The concentrations in bone broth vary widely based on preparation, so broth made with joint-heavy cuts (knuckles, chicken feet, oxtails) will deliver more of these compounds than broth from bare marrow bones.
For skin, the glycine and proline in bone broth directly support collagen synthesis. Glycine maintains skin structure and firmness, while proline stimulates the production of new collagen, helping skin recover from sun exposure and daily environmental stress. Hyaluronic acid, also present in well-made broth, draws water into skin cells, contributing to a plumper, more hydrated appearance. These effects are gradual. You won’t notice a difference after one cup, but daily intake over several weeks can contribute to visible changes in skin texture and joint comfort.
Sleep Quality and Glycine
One of the less obvious benefits of daily bone broth is its potential to improve sleep. Clinical research has found that roughly 3 grams of glycine taken before bedtime can improve sleep quality, helping people fall asleep faster and feel more rested the next day. Glycine works by lowering core body temperature, a signal that helps initiate sleep, and by calming neural activity.
Whether a single cup of bone broth delivers the full 3 grams depends on the batch. A richly gelatinous broth made from collagen-heavy bones and simmered for 12 to 24 hours will get closer to that threshold than a lighter, shorter-cooked version. Drinking bone broth as part of your evening routine, even if it falls slightly short of 3 grams, still contributes glycine that your body can use. Pairing it with other glycine-rich foods at dinner (like chicken or pork with the skin on) can help you reach the effective range.
The Lead Question
Bones store small amounts of lead accumulated over an animal’s lifetime, and some of that lead leaches into broth during cooking. This is the most common safety concern raised about daily consumption. A widely cited study measured lead at 7.01 micrograms per liter in chicken bone broth and 9.5 micrograms per liter in broth made from skin and cartilage. For context, the EPA’s safety threshold for lead in drinking water is 15 micrograms per liter.
So bone broth does contain more lead than plain tap water (which tested at 0.89 micrograms per liter in the same study) but still falls well below the EPA’s limit for drinking water. If you’re consuming one cup per day, your lead exposure from broth is a fraction of what you’d get from a full liter. The practical risk is very low for most adults. People who are pregnant or giving broth to young children may want to limit intake to a few times per week or choose broth made from pasture-raised animals, which tend to have lower lead accumulation.
Watch the Sodium
For daily drinkers, sodium is a more relevant concern than lead. Commercial bone broths can contain 500 mg or more of sodium per cup. Swanson’s cooking stock, for example, contains 510 mg per serving. If you’re also eating other prepared foods throughout the day, a daily cup of high-sodium broth adds up fast against the recommended limit of 2,300 mg per day.
You have a few options. Look for products labeled “low sodium,” which contain 140 mg or less per serving. Choose “reduced sodium” versions, which have at least 25% less than the regular product. Or make your own at home, where you control the salt entirely. Homemade broth with no added salt gets its flavor from roasted bones, aromatics, and a splash of apple cider vinegar, and can taste surprisingly full-bodied while keeping sodium negligible.
Getting the Most From Daily Broth
Not all bone broth is created equal, and the gap between a weak batch and a nutrient-dense one is significant. If you’re committing to a daily habit, a few factors determine what you’re actually getting. Cooking time matters most: simmering for at least 12 hours (and up to 24 for beef bones) extracts substantially more collagen, minerals, and amino acids than a quick 4-hour simmer. Adding a tablespoon of vinegar to the pot helps pull minerals from the bones into the liquid.
The type of bones makes a difference too. Joints, knuckles, and feet are collagen-rich and produce a broth that gels when refrigerated, a sign of high gelatin content. Marrow bones add fat and flavor but contribute less collagen. The best batches use a mix of both. If you’re buying rather than making, look for brands that gel in the fridge or list protein content of 8 grams or more per cup, which indicates meaningful collagen extraction.
One cup daily is the most common recommendation and a reasonable starting point. Some people drink two to three cups, especially during recovery from illness or intense physical training, without issues. The main reasons to moderate intake are sodium (in salted versions) and calorie considerations if you’re using a broth high in fat from marrow bones. Otherwise, bone broth is a whole-food source of nutrients that most people can safely and beneficially include as a daily habit.
