The Collagen Industry Has a Dirty Secret
Walk into any health food store or scroll through Instagram for five minutes and you'll be bombarded with collagen powders, capsules, and gummies — each one promising to transform your skin, joints, and gut in just a few weeks.
The collagen supplement industry is worth billions. And it's built on a simple premise: extract collagen from animal sources, process it into a powder, and sell it back to you at a premium.
But here's the question nobody in the supplement industry wants you to ask: is isolated collagen powder actually better than getting collagen the way humans have for thousands of years — from slow-cooked bone broth?
The answer, backed by science and common sense, is no. And in this article, we're going to show you exactly why.
What Is Collagen Powder, Exactly?
Collagen powder — also sold as "hydrolysed collagen" or "collagen peptides" — is made by breaking down animal collagen (usually from bovine hides, fish scales, or pork skin) into smaller peptide fragments through a process called hydrolysis.
The result is an odourless, flavourless powder that dissolves easily in liquids and is marketed as a convenient way to boost your collagen intake.
On the surface, it sounds ideal. But when you look more closely at what's actually in the tub, things get more complicated.
The problems with collagen powder
1. It's a processed food product. Collagen powder goes through extensive industrial processing — acid treatment, enzymatic hydrolysis, filtration, spray-drying — before it reaches your spoon. This processing strips away many of the co-factors, minerals, and nutrients that make whole-food collagen sources so effective.
2. It contains only collagen. Collagen powder gives you collagen peptides — and that's it. No glycine in its natural matrix, no gelatin, no minerals, no amino acid cofactors. Collagen doesn't work in isolation in the body. It needs supporting nutrients to be synthesised and utilised effectively.
3. Quality varies enormously. The collagen supplement industry is largely unregulated. The source of the collagen, the processing methods, and the actual collagen content can vary wildly between brands — and most of it is never independently verified.
4. It's expensive for what it is. Premium collagen powders can cost €40–80 per month. You're paying a significant premium for a highly processed, isolated extract — when a whole-food alternative exists.
What Makes Bone Broth Different?
Bone broth is made by slowly simmering animal bones — beef, chicken, or a combination — in water for an extended period. The Osso slow-cooks their broth for 18 hours.
During this long cooking process, something remarkable happens. The heat and water gradually break down the collagen and connective tissue in the bones, releasing:
Collagen — in its natural, whole-food form.
Gelatin — the cooked form of collagen, with unique gut-healing properties.
Glycine — the primary amino acid in collagen, with benefits for sleep, liver function, and inflammation.
Proline and hydroxyproline — key amino acids for skin elasticity and wound healing.
Glutamine — essential for gut lining integrity.
Minerals — calcium, magnesium, phosphorus, potassium, extracted directly from the bones.
Chondroitin and glucosamine — compounds that support joint health and cartilage repair.
In other words, bone broth delivers collagen exactly as nature intended — embedded in a complex matrix of complementary nutrients that work together synergistically.
This is something collagen powder simply cannot replicate.
The Bioavailability Argument — Does It Actually Matter?
Proponents of collagen powder often argue that hydrolysed collagen peptides are more bioavailable than the collagen in bone broth — that the smaller peptide fragments are easier for the body to absorb.
This argument sounds compelling. But it misses a critical point.
Bioavailability is only meaningful if the nutrient actually does something once absorbed. And collagen doesn't work alone. It requires vitamin C, zinc, copper, and specific amino acid cofactors to be properly synthesised and deposited in the tissues where you need it.
Bone broth naturally provides many of these cofactors in the same serving. Collagen powder provides none of them.
Furthermore, a 2021 review published in Nutrients found that the bioavailability differences between hydrolysed collagen peptides and food-derived collagen are relatively modest in practice — and that the additional nutritional complexity of whole-food sources like bone broth may offset any marginal absorption advantage of isolated peptides.
The idea that more bioavailable automatically means more effective is a marketing claim, not a scientific conclusion.
The Gut Health Advantage: Gelatin
One of the most significant advantages of bone broth over collagen powder is something the supplement industry rarely talks about: gelatin.
Gelatin is what gives properly made bone broth its characteristic jiggly texture when cooled. It's the cooked form of collagen, and it has a unique set of properties that isolated collagen peptides lack.
Research has shown that gelatin soothes and repairs the gut lining, reducing intestinal permeability; supports the growth of beneficial gut bacteria; reduces gut inflammation; and improves digestion by stimulating gastric acid production.
Collagen powder, which has been hydrolysed beyond the point of gelatin formation, provides none of these gut-specific benefits.
For anyone dealing with digestive issues, bloating, IBS, or simply wanting to support long-term gut health, bone broth is significantly more effective than collagen powder.
Real Minerals vs. Synthetic Additions
Another key difference: bone broth contains naturally occurring minerals extracted directly from bone — calcium, magnesium, phosphorus, and potassium. These are bioavailable in their natural ionic form, integrated into the broth matrix.
Many collagen powders add synthetic vitamins and minerals (particularly vitamin C) to their formulas to make up for what the processing removes. But synthetic micronutrients have lower bioavailability than their whole-food counterparts, and there's growing evidence that isolated synthetic vitamins behave differently in the body than those found in food.
When you drink bone broth, you're getting real minerals from real bones. When you take collagen powder enriched with synthetic vitamin C, you're getting a supplement trying to compensate for its own inadequacies.
Cost: The Real Comparison
Let's talk about price — because this is where the argument for collagen powder completely falls apart.
A typical collagen powder costs €40–80 per month for a daily dose. Premium grass-fed or marine collagen can cost even more.
The Osso bone broth sticks are a whole-food collagen source with a full nutritional matrix — glycine, gelatin, minerals, glutamine — at a fraction of the equivalent collagen powder cost per serving.
You're not just getting more nutrition per euro. You're getting nutrition in a form the body actually recognises and uses.
When Might Collagen Powder Be Useful?
To be fair: collagen powder has its place.
For people who are vegan or vegetarian and unwilling to consume animal products in any form, collagen powder from specific sources may be their only option (though plant-based "collagen boosters" are a different category entirely).
For athletes needing very high, precise doses of specific collagen peptides for targeted joint recovery, clinical-grade hydrolysed collagen products may have a role in a supplementation protocol.
And for people who genuinely cannot tolerate the taste or format of bone broth, collagen powder is better than nothing.
But for the vast majority of people — those looking to improve skin, support joints, heal the gut, and nourish their body from the inside out — bone broth is the superior choice, full stop.
The Bottom Line
Collagen powder is a processed, isolated extract of a single nutrient. It's expensive, heavily marketed, and missing the nutritional complexity that makes collagen effective in the body.
Bone broth is a whole food. It delivers collagen in its natural matrix, alongside gelatin, glycine, minerals, and a full spectrum of complementary nutrients. It's been nourishing human bodies for thousands of years — and the science is increasingly confirming what traditional food cultures always knew.
If you're choosing between a tub of powder and a cup of real bone broth, the answer is clear.
“Choose the whole food. Choose The Osso.”
Frequently asked questions
- Is bone broth better than collagen powder for skin?
- For skin health, bone broth has a significant advantage. It provides collagen alongside the amino acids, minerals, and gelatin that support skin elasticity and hydration. Collagen powder provides isolated peptides without the supporting nutritional matrix your skin needs to use them effectively.
- Can I take collagen powder and bone broth together?
- Yes, they're not mutually exclusive. However, for most people, a daily serving of high-quality bone broth will provide more overall benefit than collagen powder alone — and combining the two offers diminishing returns compared to the cost.
- How long does it take to see results from bone broth?
- Most people notice improvements in digestion and energy within 2–3 weeks of daily consumption. Skin, hair, and joint benefits typically become noticeable after 6–8 weeks of consistent use.
- Is bone broth collagen the same as hydrolysed collagen?
- No. Bone broth contains collagen in its natural form, as well as gelatin and a full amino acid profile. Hydrolysed collagen has been processed to break down the collagen molecules into smaller peptides, removing the gelatin and much of the nutritional complexity.
- How much collagen is in a bone broth stick?
- The Osso bone broth sticks are made from 18-hour slow-cooked broth, concentrated into a 10ml stick. Each stick provides naturally occurring collagen, gelatin, and glycine from real animal bones — without synthetic additives or isolates.
