Collagen peptides: Small building blocks, big impact

Collagen – most people are now familiar with this protein, whether through collagen capsules or other sources, as it can help give skin, hair, ligaments, tendons, cartilage, bones, and muscles greater elasticity and strength. But what exactly are collagen peptides? The answer has to do with size. Let’s take a closer look:

Collagen is a structural protein. It is large and relatively heavy. When broken down, it forms tiny protein molecules. And these are exactly what are called peptides.

So let’s summarize: While collagen refers to the complete structural protein, collagen peptides are smaller protein fragments with a reduced composition. Understanding this difference can help explain the collagen capsules benefits often discussed in relation to skin, connective tissue, and overall well-being. Each of these contains either primarily glycine and proline, along with other amino acids in smaller amounts, or glycine, hydroxyproline, and other amino acids in smaller quantities.

Let’s take a closer look at another term: collagen hydrolysate. What exactly is it? And how is this term related to the word “peptide”?

Here, we find the answer in the production of these tiny collagen particles called peptides: To obtain these fragments, an enzymatic breakdown—also known as hydrolysis—is required. So, bovine or fish collagen, commonly used in marine collagen capsules, is broken down or hydrolyzed using special enzymes at a very specific temperature. And the result of this process—these tiny components—is called hydrolysate. Collagen hydrolysate is therefore nothing more than a synonym for collagen peptides.

But why would you want to break down collagen into smaller pieces in the first place? What are the benefits of these collagen peptides? You need to know that whole collagen has a high molecular weight. This can sometimes make it difficult for your gut to absorb. However, if it is broken down into individual molecules, or peptides, not only does the weight decrease, but bioavailability increases at the same time. Your gut therefore copes much better with these collagen building blocks than with the large, complex puzzle – which is why collagen peptides are often used in collagen capsules.

Incidentally, your digestive system breaks down the hydrolysed collagen again, turning it into individual amino acids. These then pass through the intestinal lining into your blood – and from there exactly where you need them. The following key areas benefit most from this:

Your skin: Collagen peptides can improve your skin’s elasticity, reduce wrinkles, minimise cellulite and partially counteract age-related collagen loss. You also optimise skin hydration, cell regeneration and wound healing.

Your joints: Collagen peptides help you maintain the health of your joints and prevent collagen breakdown in the cartilage. Joint pain is thus a thing of the past and you are more mobile.

Your muscles: If you treat your body to collagen peptides, you can look forward to the following benefits: the increased protein intake makes it easier for you to build lean muscle mass. If you also exercise regularly, this will help you lose fat at the same time.

When it comes to collagen, a distinction can be made between the following types:

Type I: This collagen is found primarily in your skin, connective tissue, bones, tendons and ligaments. In total, it accounts for around 90% of your body’s collagen.

Type II: This type of collagen is found in cartilage.

Type III: This collagen is also found in the skin and connective tissue.

As all types of collagen are hydrolysed and purified, there is no need to limit yourself to a specific type. The body can utilise all types of collagen equally and incorporates the collagen peptides and amino acids into the skin and joints as required.

You can take collagen peptides in the form of collagen capsules or collagen powder. Drinkable vials are also available. It is essential to ensure you take them regularly every day over a prolonged period to achieve the best results. You can usually expect to see the first improvements after about three months.

Sometimes it’s worth paying attention to the details – for example, when it comes to collagen peptides. That’s because these tiny particles not only contain important amino acids, but are also incredibly light. This means they reach exactly where you want them in your body in no time at all.
