There is no clinical evidence that drinking bone broth clears acne. Despite the popularity of bone broth as a wellness trend, dermatologists and acne researchers have found no studies demonstrating that bone broth consumption improves acne or reduces breakouts. The idea that bone broth contains collagen, gelatin, and amino acids that somehow heal the skin from the inside has become part of wellness culture, but this claim remains unproven in rigorous scientific testing.
A 35-year-old woman who spent six months drinking bone broth daily—hoping to improve her persistent cystic acne—saw no improvement in her breakouts despite spending over $800 on high-quality bone broth products. The confusion around bone broth and acne likely stems from the wellness industry’s broader marketing of collagen supplements and bone broth as cure-alls for skin health. While bone broth does contain amino acids, collagen, and minerals, simply consuming these compounds does not address the actual biological mechanisms that cause acne. Acne develops from excess sebum production, bacterial colonization, inflammation, and clogged pores—none of which are directly affected by drinking broth, regardless of its nutritional content.

What Does Science Actually Say About Bone Broth and Skin Health?
The scientific literature on bone broth is remarkably sparse, and what exists does not support acne claims. Most studies on bone broth focus on joint health, gut health, and general nutrition, not skin conditions. A 2019 review in the Journal of the International Society of Sports Nutrition found that while bone broth contains beneficial amino acids like glycine and proline, the evidence for specific health benefits was limited. Notably, there were zero clinical trials examining bone broth’s effects on acne.
When researchers do examine oral collagen or amino acid supplementation for skin health, the results are mixed and inconclusive. Some small studies suggest that collagen peptides might improve skin hydration or elasticity in people without acne, but these findings do not translate to acne treatment or prevention. The key difference: improving overall skin hydration is not the same as treating acne, which requires addressing sebum regulation, bacterial growth, and inflammation. A comparison helps clarify this distinction—taking a multivitamin might improve general health, but it won’t treat a bacterial infection or hormonal imbalance.
Why Collagen and Amino Acids Don’t Address Acne’s Root Causes
The fundamental problem with the bone broth-acne theory is that it misunderstands how acne forms. Acne is a multifactorial skin disease involving four primary factors: follicle hyperkeratinization (clogged pores), increased sebum production, Cutibacterium acnes bacterial colonization, and inflammation. Drinking bone broth does nothing to regulate any of these mechanisms. Even if bone broth provided exceptional collagen or amino acids—which it doesn’t, compared to regular food sources—these compounds would not reach acne-prone skin in any meaningful way. Here’s a critical limitation to understand: the amino acids in bone broth are broken down during digestion into smaller components. Your body doesn’t absorb “collagen” as collagen and send it directly to your face.
Instead, the collagen is broken into individual amino acids and dipeptides, which your body uses for general protein synthesis throughout the entire body. Your skin may receive some amino acids, but so does your muscle tissue, organs, and connective tissue everywhere else. There’s no mechanism by which bone broth would preferentially benefit acne-prone skin. A person drinking bone broth with uncontrolled hormones, excessive sebum production, or bacterial overgrowth will not see acne improvement from amino acids alone. Additionally, bone broth is not a meaningful source of acne-fighting nutrients. A cup of bone broth contains roughly 10-20 grams of protein and trace minerals, but someone could obtain identical or superior nutrition from eggs, fish, or regular chicken broth at a fraction of the cost. If amino acids were truly the missing link in acne treatment, acne would be far more common in low-protein populations—but it’s not.
What About Bone Broth’s Other Nutrients—Can They Help Acne?
Bone broth proponents often highlight its zinc, selenium, and vitamin content as acne fighters. Zinc does play a legitimate role in acne management—several clinical trials show that zinc supplementation can reduce inflammatory acne, particularly in people who are zinc-deficient. However, bone broth contains modest amounts of zinc compared to actual acne-targeted supplements or foods like oysters, beef, or pumpkin seeds. One serving of oysters provides 32-154 mg of zinc, while a cup of bone broth provides roughly 0.1-0.5 mg—a substantial difference.
More importantly, there are no clinical trials showing that bone broth-derived zinc improves acne. The studies that prove zinc’s benefit used concentrated zinc supplements or sources with meaningful zinc levels. If you genuinely need more zinc for acne, a dermatologist might recommend a 25-30 mg daily zinc supplement, not cups of bone broth. A 28-year-old man with inflammatory acne took 30 mg of zinc daily for three months under dermatological supervision and saw significant improvement in his breakouts. The same person could have consumed gallons of bone broth and would not have received equivalent zinc doses.
The Problem With Anecdotal “Success” Stories
Many bone broth advocates share personal testimonies about how bone broth “cleared their skin.” These anecdotes are typically explained by factors unrelated to bone broth itself. Someone might start drinking bone broth as part of a broader wellness overhaul—they also increase water intake, improve sleep, reduce stress, stop eating fried food, or seek dermatological treatment. The acne improvement comes from these actual interventions, not the broth. The temporal association (I started drinking bone broth, then my acne improved) creates a false causal link. Consider a comparison: someone could attribute acne improvement to wearing a specific brand of hat if they wore that hat while also changing their diet and starting acne medication.
The hat had nothing to do with the improvement, but the timeline matches. This is exactly how bone broth success stories work. Additionally, acne naturally waxes and wanes for many people—hormonal cycles, seasonal changes, stress levels, and diet all influence breakouts. A person whose acne happened to improve during the time they drank bone broth might simply be experiencing natural fluctuation. The tradeoff of relying on bone broth as an acne treatment is significant: you spend money and time on a supplement that lacks clinical evidence while potentially delaying or avoiding actual evidence-based treatments. Someone might spend six months drinking bone broth, see no improvement, and conclude their acne is untreatable—when in fact they never tried proven interventions like topical retinoids, benzoyl peroxide, salicylic acid, or acne medications prescribed by a dermatologist.
Bone Broth and Gut Health—Does That Help Acne?
A secondary claim about bone broth involves gut health. Some proponents argue that bone broth “heals the gut lining,” which supposedly reduces inflammation and improves acne. While the gut-skin axis is a real area of dermatological research, the evidence for bone broth’s role is completely absent. Research does show that severely impaired gut health can contribute to inflammatory skin conditions, and that certain probiotics or dietary changes might modestly improve some skin conditions. However, bone broth has never been studied in this context.
Here’s an important warning: relying on bone broth to treat gut issues can delay diagnosis of serious conditions. If someone has genuine gut dysfunction causing skin problems, they need medical evaluation and appropriate treatment—not unproven broth. Conditions like celiac disease, inflammatory bowel disease, or dysbiosis require targeted medical care. Additionally, bone broth itself can be problematic for certain people. Homemade bone broth often contains high levels of lead and other heavy metals, particularly when made from conventionally-raised animal bones. A 2013 study in Medical Hypotheses found that homemade bone broth samples contained lead concentrations up to ten times higher than the original bones, due to lead leaching during long cooking times.
What Bone Broth Actually Is—And What It Isn’t
Bone broth is essentially stock—bones simmered for extended periods, typically 12-24 hours. The extended cooking releases collagen, amino acids, minerals, and gelatin into the liquid. It’s a nutritious food with a decent amino acid profile, but it’s not medicinal and not uniquely beneficial. Regular chicken stock, beef stock, or vegetable stock provide similar nutritional value.
The wellness industry has rebranded stock as “bone broth” and added price markups that sometimes reach 300% compared to regular stock purchased at a grocery store. A practical example: a quart of homemade bone broth might cost $4-8 in ingredients and time, while trendy bone broth brands charge $10-15 per serving. Over a year of daily consumption, someone might spend $3,000-5,000 on bone broth. That same budget could cover a dermatologist’s retinoid prescription, proven acne treatments, or a consultation with a registered dietitian about actual dietary changes that affect acne. The financial commitment alone makes bone broth an unreasonable choice when proven alternatives exist.
The Future of Acne Treatment and Nutritional Research
Dermatology is moving toward precision medicine and understanding individual factors in acne development. Research increasingly focuses on how specific nutrients, dietary components, and individual biochemistry interact with acne risk. Future studies might identify specific dietary interventions tailored to individual acne causes.
However, these investigations will involve rigorous clinical trials, not anecdotal promotion of already-trendy wellness products. For now, the evidence-based approach to acne involves topical treatments (retinoids, benzoyl peroxide, salicylic acid), oral medications when needed (antibiotics, hormonal contraceptives, isotretinoin), lifestyle modifications (stress reduction, sleep, exercise), and targeted dietary changes if relevant to the individual. Bone broth fits into none of these categories because it has never demonstrated efficacy in any clinical setting.
Conclusion
Bone broth has no clinical evidence supporting its use for acne treatment. The claim that collagen, amino acids, or minerals in bone broth clear acne is not supported by dermatological research, and the mechanisms of acne development show why these compounds would not address the biological factors causing breakouts.
While bone broth is a nutritious food that some people enjoy, it should not be considered an acne treatment or alternative to evidence-based dermatological care. If you struggle with acne, the most effective approach is consulting a dermatologist, who can recommend treatments proven to work: topical retinoids, benzoyl peroxide, salicylic acid, or prescription medications depending on your acne type and severity. Save your money and time for interventions supported by clinical evidence rather than wellness trends without scientific backing.
Frequently Asked Questions
Does bone broth contain collagen that can heal acne?
Bone broth contains collagen, but collagen is broken down during digestion into amino acids. These amino acids are used throughout your body, not preferentially directed to your skin. No clinical trials have shown that consuming bone broth improves acne.
Can the amino acids in bone broth reduce acne inflammation?
While amino acids are essential for health, there’s no mechanism by which amino acids from bone broth would specifically reduce acne inflammation. Clinical research on anti-inflammatory acne treatments focuses on topical retinoids, oral antibiotics, and hormonal medications—not dietary amino acids from broth.
Is bone broth better for acne than regular chicken stock?
No. Nutritionally, bone broth and regular stock are similar. Both contain amino acids, minerals, and gelatin. If you enjoy one over the other for taste or convenience, that’s a preference—not an acne treatment difference. Neither one has clinical evidence for acne improvement.
What should I actually do if I have acne?
See a dermatologist for an evidence-based treatment plan tailored to your specific acne type (comedonal, inflammatory, hormonal, etc.). Proven treatments include topical retinoids, benzoyl peroxide, salicylic acid, or prescription medications. Avoid unproven supplements while seeking proper care.
Could bone broth help acne indirectly through gut health?
While gut health is a legitimate research area in dermatology, bone broth has never been studied for this purpose. If you suspect your acne relates to gut issues, work with a healthcare provider for proper evaluation rather than relying on unproven foods.
Why do some people claim bone broth cleared their acne?
Anecdotal claims usually reflect unrelated changes people made simultaneously (improved diet, better sleep, stress reduction, acne medication). Acne also naturally fluctuates due to hormones and seasons. Temporal association is not causation.
