Bone Broth and Collagen for Skin: Do They Actually Work?
Does bone broth help your skin? Probably not much. Bone broth is a warm, protein-rich food, but lab testing shows it does not give you a reliable dose of collagen building blocks. Collagen supplements have more research, but a 2025 review found their skin benefits disappeared in the highest-quality, non-industry-funded studies. That review has been challenged, so the honest answer is: unproven.
Why bone broth is trending
Pinterest's October 6, 2026 beauty report said food-based beauty is rising, and listed "bone broth benefits for women" up 782%. It also mentioned rosemary water, avocado, rice water, turmeric and olive oil. [1] Pinterest did not share raw volumes.
What is actually in bone broth
Bone broth is made by simmering bones and connective tissue for 12 to 48 hours. The Conversation, in a 2025 explainer by academics, notes that this pulls some collagen, amino acids, and minerals into the liquid, and that broth is low in calories and high in protein. But it says most skin studies were done on collagen supplements, and research shows bone broths do not contain enough collagen to match the effects seen in those studies. [4]
A 2019 lab study tested bone broths against a 20 gram collagen supplement dose. Standardized broths had much lower levels of collagen building blocks such as glycine, proline, and hydroxyproline. Homemade and café broths varied widely. The authors concluded broth is unlikely to provide reliable amounts. [2]
What about collagen supplements?
A 2025 systematic review and meta-analysis in the American Journal of Medicine pooled 23 randomized trials with 1,474 people. Overall, collagen seemed to help skin hydration, elasticity, and wrinkles. But when the authors looked only at studies without pharmaceutical company funding, or only at high-quality studies, there was no significant benefit. Their conclusion was that there is no clinical evidence supporting collagen for skin aging. [3]
Important caveat: after publication, letters to the journal and industry groups argued the review made errors in how it classified funding and some study details. So this is a live debate, not a final verdict. What is clear is that the strongest evidence is weaker than the marketing.
Flagging the money (original)
Many collagen trials are paid for by companies that sell collagen. That does not make them wrong, but it is a reason to be careful when you see a big "clinically proven" claim on a tub.
What is proven for skin (original summary)
| Habit | How strong is the evidence? | |---|---| | Daily sunscreen | Strong, for preventing sun aging | | Not smoking | Strong | | Retinoids | Strong, for fine lines over months | | Enough protein and a varied diet | Good for overall health; skin effects indirect | | Collagen supplements | Mixed and contested | | Bone broth | Weak for skin specifically |
If you like bone broth
There is nothing wrong with it as food. It is warming, filling, and an easy way to add protein. Practical tips (original):
- Watch the salt. Store-bought broth can be very salty. Check labels.
- Price check. Premium broth is expensive per gram of protein compared with eggs, beans, or chicken.
- Food safety. Cool homemade broth quickly and refrigerate. Do not leave it out overnight.
A smarter budget (original)
If you were going to spend money on collagen powder or bone broth for skin, here is a swap:
- A sunscreen you like enough to wear every day
- A basic retinoid for night
- A protein-rich breakfast
That covers the habits with the most evidence.
Quick answers
Does collagen go straight to your skin? No. Your body breaks it into amino acids and uses them wherever needed.
Is vegan collagen real? Plant products cannot contain animal collagen. "Collagen boosters" usually contain vitamin C and amino acids.
Can bone broth help my hair or nails? There is no good evidence it does.
The bottom line
Bone broth is a cozy, protein-rich food, not a skin treatment. Collagen supplements have mixed, disputed evidence, and much of the positive research is industry-funded. Spend first on sunscreen, a retinoid, and a solid diet.
