Bone broth is not high in iron. In fact, most bone broth contains so little iron that commercial brands list it as 0% of your daily value on their nutrition labels. Despite its reputation as a nutrient-dense superfood, bone broth is one of the least reliable sources of iron you can choose.
How Much Iron Bone Broth Actually Contains
The numbers are surprisingly low. Multiple commercial bone broth products, including grass-fed beef bone broth and organic chicken bone broth, register at 0% of the daily value for iron per serving. That means a cup of bone broth delivers less than half a milligram of iron, which rounds down to zero on a nutrition label.
To put that in perspective, adult men need about 8 mg of iron per day, and women between 19 and 50 need 18 mg. Even if you drank several cups of bone broth daily, you’d barely make a dent in those requirements. A single serving of red meat, lentils, or fortified cereal provides more iron than an entire pot of bone broth.
Why Bones Don’t Release Much Iron
The logic behind bone broth sounds reasonable: bones contain minerals, so simmering them for hours should pull those minerals into the liquid. In practice, this doesn’t happen efficiently. Bone is an extremely dense, mineralized tissue, and the conditions inside a stockpot simply aren’t aggressive enough to break it down in a meaningful way.
A popular home-cooking tip suggests adding apple cider vinegar to your broth to help extract minerals from the bones. The idea is that the acid will dissolve the mineral matrix. But apple cider vinegar has a pH of around 2.4, and meaningfully extracting minerals from bone requires much stronger acid over much longer timeframes, on the order of days to weeks rather than hours. Studies comparing broths made with and without vinegar found negligible differences in mineral content. The vinegar isn’t harmful, but it’s not turning your broth into a mineral supplement either.
What Bone Broth Does Offer
None of this means bone broth is nutritionally worthless. It provides collagen-derived proteins like gelatin and amino acids such as glycine and proline, which support joint health and gut lining repair. It’s a good source of protein for a liquid food, and it delivers meaningful amounts of sodium, which makes it useful for hydration. The problem is specifically with minerals. Calcium, iron, and potassium are all present in only trace amounts, far below what you’d get from whole foods like leafy greens, beans, or meat.
Better Iron Sources to Consider
If you’re looking to increase your iron intake, whole foods are far more effective than broth. A 3-ounce serving of beef delivers around 2 to 3 mg of iron in its most absorbable form (heme iron, the type found in animal tissue rather than in bones). On the plant side, a cup of cooked lentils provides about 6.6 mg, and a cup of cooked spinach offers around 6 mg.
Plant-based iron is harder for your body to absorb than the iron in meat, but pairing it with vitamin C dramatically improves uptake. Adding bell peppers, tomatoes, citrus, broccoli, or strawberries to an iron-rich meal helps your body pull more iron from plant sources. Something as simple as squeezing lemon juice over lentil soup or adding tomato to a bean dish makes a real difference in how much iron you actually absorb.
The Bottom Line on Bone Broth and Iron
Bone broth has genuine nutritional benefits, but iron isn’t one of them. The mineral content is negligible regardless of whether you buy it commercially or simmer it at home for 24 hours with vinegar. If you’re drinking bone broth for the collagen, the amino acids, or simply because you enjoy it, those are valid reasons to keep it in your routine. If you’re drinking it to address low iron levels, you’ll need to look elsewhere.
