If you’re over 45, there’s a decent chance your joints have started narrating your day

A wince at the stairs. Achy joints after a round of golf or a game of tennis.  The “rusty hinge” feeling in your fingers when you first wake up…

Most of us have been told some version of, “well, that’s just about getting older.” And ageing is real, yes. But so is the desire to keep doing the things we love, without paying for it for days afterwards.

One new joint supplement brand, NIMBL, is trying to tackle that gap using a rather unexpected ingredient from the deep, cold waters off Norway. Short-chain chitosan is derived from shrimp shells caught in the icy waters around Tromsø, Norway – and the results are striking.

“I’m back doing things I thought were behind me”

Before we get into the science, it’s worth listening to the people already taking it. Customer Mike suffered years of stiffness and discomfort before finding relief. He now describes himself as “back doing things I thought were behind me” and walking without the pain that had quietly shrunk his world.

Another reviewer, a primary school teacher on her feet all day, says her aches, stiff joints and inflammation eased within weeks, and that NIMBL has become part of her daily routine – not something she plans to give up.

A daughter writes about her dad, still out surfing and windsurfing in later life, and credits NIMBL with helping him keep moving the way he prefers – on the water, not on the sofa.

You’ll find many more customers talking about reduced pain in fingers, knees and feet within a couple of weeks, getting back to the parts of life they love.

It’s not a miracle cure; results vary and consistency matters. But the common thread is striking: less stiffness, more ease, and a quiet sense of getting bits of life back.

What’s really going on in those creaky joints?

When it comes to joints, it isn’t just “wear and tear”. As we get older, many of us live with a background level of chronic, low-grade inflammation sometimes called “inflammaging”. It’s not the dramatic swelling you might get from an injury, but a gentler, ongoing simmer that can affect cartilage, joint fluid and the tissues around them.

In real life, it feels like:

• Stiff knees when you get out of bed
• Tight hips when you stand up after sitting
• Hands that don’t fancy opening jars or gardening for long
• Paying for exercise with two days of “ouch” instead of a nice glow

From prawn shells in Norway to a capsule on your kitchen counter

At the centre of NIMBL is something called short-chain chitosan. If that sounds like a sci-fi villain, don’t panic – here’s the plain-English version.

Chitosan is a natural substance found in the shells of crustaceans, like prawns and crabs. NIMBL uses prawn shells pulled from the wild, icy waters around Tromsø – shells that would otherwise be waste.

Those shells are carefully cleaned and processed in a way that breaks the chitosan down into smaller, “short-chain” pieces.

Why bother making it smaller? In simple terms, size matters for absorption. Short-chain chitosan is “highly bioavailable”: small enough for your body to absorb and use more quickly, so it can get where it’s meant to go – your joints.

Instead of throwing a long list of ingredients into one capsule and hoping something sticks, the  formula is built around this single, well-studied compound, plus a handful of supporting ingredients, and leaves out the usual “fluff” and fillers.

Thinking about joint supplements?

Whether you’re curious about NIMBL specifically or joint supplements in general, a few common-sense steps apply:

• Talk to your GP or pharmacist, especially if you’re on other medication or have existing health conditions.
• Check the ingredient list. Do you understand what’s in there and why?
• Be realistic about timelines. Your joints won’t transform in a week; think in terms of weeks to months, not days.

And finally, remember that supplements are just one tool. The basics still matter: regular movement you actually enjoy, decent sleep, good food, less stress where you can manage it, and a social life that doesn’t revolve entirely around your sofa.

Getting older is inevitable. Feeling like your world is shrinking doesn’t have to be.
