Collagen Protein and Antioxidant Support: What Research Reveals
When most people think of collagen, they think of skin, joints, and healthy ageing. But did you know collagen supplements may also support your body’s natural antioxidant defences?
At Nutraviva, we’re passionate about clean, effective food supplements backed by science. New research is shedding light on the antioxidant benefits of collagen protein powders and the potential these bioactive peptides have in promoting cellular protection, skin vitality, and overall wellness.
Collagen Protein: More Than Just Skin Deep
Collagen is the most abundant structural protein in the body. When broken down into smaller protein chains (collagen peptides), collagen becomes easier to digest and absorb, making collagen supplements a valuable addition to any wellness routine.
While we already know that collagen supplements can support joint function, hair growth, and skin elasticity, studies show that collagen hydrolysate may also have antioxidant properties, helping protect cells from oxidative stress and free radical damage.
What the Science Says: Hydrolysed Collagen and Antioxidant Activity
A study published in Food Science and Technology evaluated hydrolysed marine collagen and found significant antioxidant activity after enzymatic processing (Alemán, Giménez, Montero & Gómez-Guillén, 2011).
Key findings include:
- Hydrolysed collagen doubled its antioxidant capacity compared to unprocessed gelatin.
- Collagen peptides demonstrated both radical scavenging (measured by ABTS assay) and iron-reducing power (measured by FRAP assay), which are both markers of antioxidant activity.
- Antioxidant capacity improved with the degree of hydrolysis, indicating that smaller peptides may be more effective.
These results suggest that hydrolysed collagen isn't just about structural support; it may also provide protective antioxidant benefits at the cellular level.
Why Does Antioxidant Support Matter?
Free radicals are unstable molecules that can damage cells and accelerate ageing, inflammation, and degenerative conditions. Antioxidants are compounds that help neutralise these free radicals. While many people turn to vitamin C or E, bioactive peptides from collagen are emerging as natural antioxidants that can be part of a broader health-supporting routine (Edgar, Hopley, Genovese, Sibilla, Laight & Shute, 2018).
In addition to skin and joint benefits, collagen protein may help:
- Reduce oxidative stress
- Protect against premature ageing
- Support recovery and immune health
Choosing High-Quality Collagen Protein Powder
Not all collagen supplements are created equal. At Nutraviva, our pure hydrolysed collagen powders are:
- 100% natural and free from additives
- Sourced from wild-caught fish (Marine Collagen) or grass-fed cattle (Collagen Hydrolysate)
- Hydrolysed for bioavailability, thus readily absorbed
- Rich in glycine, proline, and hydroxyproline, the amino acids essential for collagen synthesis and antioxidant support
Whether you choose bovine or marine collagen powder, you’re supporting your body with clean, functional nutrition rooted in science.
Collagen isn’t just a beauty supplement; it may also be a powerful ally for your internal wellness, including your body’s ability to combat oxidative stress. The research confirms that hydrolysed collagen protein powders deliver natural antioxidant benefits alongside its well-known structural support.
