Marine Collagen: Worth the Hype, or Just Another Trend?

Another supplement getting a lot of attention lately — especially among people over 30 — is marine collagen.

But does it actually do anything? Or is it just another Instagram influencer favourite?

🧬 What Is Marine Collagen?

Collagen is the most abundant protein in your body — it helps hold everything together: skin, joints, ligaments, bones, and connective tissue.

As you age (especially after 30), collagen production starts to decline, which can lead to:

• Wrinkling or sagging skin

• Joint stiffness or aches

• Slower recovery from exercise or injury

• Brittle nails or thinning hair

Marine collagen is derived from fish and tends to be better absorbed than other sources like bovine (cow) or porcine (pig). It’s popular because it’s bioavailable, meaning you’re more likely to actually utilise it properly, light on the gut, and suitable for pescatarians.

💡 What Could It Help With?

Current research and anecdotal evidence suggest marine collagen might help with:

• Joint pain and stiffness — especially useful if you’re training regularly or returning from injury

• Skin elasticity and hydration — yes, it can make your skin look healthier over time

• Hair and nail strength

• Recovery — particularly tendon or ligament support

Is it a miracle fix? No. But for older clients or those with joint niggles, it’s potentially a smart addition.

✅ Is It Safe?

Yes. Collagen (marine or otherwise) is generally very safe, well-tolerated, and has a low risk of side effects. Some people notice mild bloating at first, but it usually settles.

Look for one with vitamin C included — which helps with absorption.

🥄 How Do You Take It?

Easy:

• 5–10g per day is enough

• Take it daily — results tend to show after 4–8 weeks of consistent use

• Optional: combine with vitamin C (either in the supplement or separately)

❌ What It Won’t Do

It won’t magically fix joint pain overnight or replace solid nutrition and training. And it’s not a replacement for protein if you’re under-eating.

But it can help support the bits you don’t think about — skin, ligaments, tendons — especially as you get older.

🧠 Bottom Line

For most of our RWF clients — especially 30+ — marine collagen is a decent option for staying ahead of the wear and tear that naturally creeps in.

It’s not essential. But if your joints are niggly, your skin’s changing, or you want to stay ahead of ageing, it’s worth a look.
