Bone Broth vs Collagen Supplements: What Each Provides and What Research Compares

Bone broth and collagen supplements are different foods and products; this page sets out what laboratory analyses show about each and where no head-to-head trial was found.

Quick answer
Bone broth and collagen supplements are not the same thing, and the sources we read do not show that one gives better health results than the other. What exists is a laboratory comparison of amino acid content, which found that broth varies widely and is lower than a reference collagen supplement amount. [1] We found no trial that compared the two on skin, joint or bone outcomes (see "Proper evidence not found" below).

What each one is

  • Bone broth is a food made by simmering animal bones. A study of how bones release minerals into broth found that cooking time, acidity and the bone used all changed what ended up in the liquid. [2]
  • Collagen supplements are usually powders, capsules or drinks that contain collagen that has been broken into smaller pieces. Terms are explained in collagen peptides, hydrolyzed collagen and collagen hydrolysate.

For what broth contains in general, see bone broth: what it contains and what research exists.

How the evidence is labeled

Where a claim comes from a laboratory analysis we say so. A narrative review is an expert summary, not a new test. Proper evidence not found means we searched and found nothing usable; we say where we looked.

What the sources compared

4 findings · 4 limited or unclearThe colour follows the evidence label on each card.

  1. Does broth supply as many collagen-building amino acids as a collagen supplement?

    Laboratory analysis of samples; not a trial in people

    Broth made to a standard recipe had significantly lower hydroxyproline, glycine and proline than a reference collagen supplement amount of 20 g. [1]

  2. Is broth consistent from one preparation to the next?

    Laboratory analysis

    Broth made to non-standard recipes varied a great deal, and bought broths were lower in all the amino acids measured than self-prepared standard broths. [1]

  3. Do broth and supplements change skin, joints or bone differently?

    None found

    Proper evidence not found. We searched PubMed for bone broth with randomized trial and with collagen and amino acids and found no such comparison.

  4. Does broth help the gut?

    Review; mixed study types

    A 2025 narrative review draws on animal and human studies and encourages further research. [3]

The authors of the amino acid study concluded that, if collagen precursors do prove to support new collagen, broth is unlikely to be a reliably consistent source of key amino acids. [1] That is a statement about content, not about health outcomes.

Evidence for the supplement side

Trials of collagen supplements are reviewed on other pages, because results depend on the product type and the outcome. A meta-analysis of 26 trials of hydrolyzed collagen reported better skin hydration than placebo and also identified several biases in the included trials. [4] See collagen for skin. None of those trials tested broth, so the results cannot be carried over to it.

No universal winner

The two are different. Broth is a food whose content depends on the recipe; a supplement is a product with a label. The sources give no basis for ranking them, and this page does not rank products.

Frequently asked questions

Is bone broth the same as collagen powder?

No. In a laboratory comparison, standard-recipe broth had significantly lower levels of several collagen-related amino acids than a 20 g reference collagen supplement amount, and broth varied widely between recipes. [1]

Does any study show broth works better than collagen supplements, or the reverse?

Proper evidence not found. We searched PubMed for bone broth with randomized trial and with collagen and amino acids and found only content analyses and reviews.

Is bone broth safe because it is a food?

Not automatically. One small study found elevated lead in some chicken broths, and another found low levels in the broths it tested. [5] [2] Ask a clinician if you have a medical condition.

Does bone broth heal the gut?

A 2025 review of animal and human studies encourages further research and does not report a trial against a collagen supplement. [3] See collagen for gut health and leaky gut claims.

Where can I read more on foods and collagen?

See foods and collagen and the Functional Foods section.

Safety and who should ask first
  • Lead and other metals. A small controlled study found that some chicken broths contained several times the lead concentration of the water used to make them. [5] A separate analysis reported that lead and cadmium in broth were a few micrograms per serving and described the risk as minimal. [2] The two studies measured different broths, so we do not treat either as the last word.
  • Variation. Because broth content varies, it is hard to say what any one serving contains. [1]
  • Supplements. Powder contamination and label accuracy are covered on collagen heavy metals, contamination and testing and quality testing and certifications.
  • Allergy. Both broth and supplements can come from beef, chicken or fish; see collagen allergy. For signs of a severe allergic reaction, such as trouble breathing or swelling of the face or throat, call 911.
  • Pregnancy, breastfeeding, children, kidney or liver conditions, medicines. Proper evidence not found in the sources we read for broth or for a head-to-head comparison. Talk to a clinician or pharmacist, and see medication interactions.
