Hydrolysed collagen: fact or fiction?

Walk into any supplement aisle—or scroll online for more than a few seconds—and you will see the same phrase repeated: hydrolysed collagen. It sounds scientific, advanced, and premium.  

But here is the reality: in most cases, you are looking at the same product, just packaged and marketed differently. This is why terms like hydrolysed collagen peptides and collagen peptides are often used interchangeably. Let’s unpack what “hydrolysed” means and why it’s not the quality marker it’s often made out to be. 

So, what is hydrolysed collagen? 

Hydrolysed collagen is simply collagen that has been broken down into smaller pieces—called peptides—through a process known as hydrolysis. 

Hydrolysation: 

This process is why a hydrolysed collagen powder blends smoothly into coffee, smoothies, or recipes without clumping. Whether you choose bovine or hydrolysed marine collagen powder, hydrolysis is what gives collagen its convenient, versatile format. 

So yes, hydrolysed collagen serves a purpose. But here is the part most brands do not emphasise: 

Almost all collagen supplements on the market today are already hydrolysed. 

It’s not a premium feature. It’s the baseline. So, when you see “hydrolysed collagen” front and centre on a label, as the key point a brand is shouting about, it’s worth asking: “What else is there?” 

The illusion of difference 

The collagen market is crowded and highly competitive. To stand out, brands often lean heavily on terminology: 

Different terms, same basic concept. Behind the scenes, many of these products start with similar raw materials, use comparable processing methods, and end up with broadly comparable end products. Yet branding, packaging, and buzzwords create the impression of meaningful differences. You are often being sold the same thing, just described in a more compelling way. 

What actually matters  

If “hydrolysed” is not the differentiator, what is? 

1. Sourcing 

Quality starts long before hydrolysis. Where the collagen comes from—and how the animals were raised—plays a significant role in overall quality. 

Look for: 

Certification is a sign of higher standards across the supply chain, and a commitment to ethics and sustainability. Planet Paleo uses certified grass-fed sourcing across its bovine range, and MSC-certified wild-caught sources in the marine collagen range.  

2. What else is in it 

Collagen should be simple. But not all products are. Some include fillers or bulking agents, artificial flavours or sweeteners, and unnecessary additives. 

A high-quality collagen keeps things clean and minimal, focusing on the ingredient itself, not what is added around it.  

3. Effective dosage 

This is where many products fall short. Clinical research typically uses specific daily amounts to observe benefits. But some collagen forms like tablets and gummies provide far less. These token amounts are enough to include on the label, but not enough to deliver noticeable results.  

If you are taking collagen for skin health, joint support, or recovery, then underdosing is something to be aware of. 

Why this matters 

It is easy to assume that a more technical-sounding label equals a better product. 

But with collagen, that is rarely the case. 

“Hydrolysed” tells you how it’s processed, not how good it is. 

And when that is the main feature being highlighted, it often means more important details are not. Instead of asking: “Is this collagen hydrolysed?” 

Ask: 

These are the factors that genuinely separate one product from another and enable you to distinguish between brands and product quality. 

The Planet Paleo perspective 

At Planet Paleo, we focus on what makes a difference: 

Just pure collagen that does what it is supposed to do.
