Why Pain-Free Movement is the New Longevity Metric

By Trent Scanlen, co-founder of KURK Biosciences

Ask any golfer what they fear most about getting older, and very few will say their handicap. They will say they are afraid of the day they can't play. Not the score, but the day they have to hand back the thing that has shaped their weekends, their friendships, and decades of their life. And it is rarely about fitness. It is the body that stops cooperating: a hip that locks up, shoulders that ache through the backswing, knees that punish every round with two days of stiffness. That fear is about movement, and it is worth taking seriously.

I have stopped worrying about how long I will live. What I think about now is how long I will be able to keep doing the things I love. For a golfer, that is the whole question, because golf is a sport built on functional movement, repeated across 18 holes and sustained over decades.

I did not come to this as a researcher. I came to it the hard way, as a founder who learned through my own body that how you handle everyday inflammation decides how well you move as you age. Everyday inflammation is closely linked to the stiffness, slower recovery and aches that build up over years of play, and it's what eventually has people putting the clubs away for good.

Here is the frustrating part. Most natural approaches to inflammation fall down, and not on the ingredients. They fall down on absorption. Curcumin is the clearest example. The active compound in turmeric has thousands of published studies behind it, yet in standard powder or capsule form, curcumin is notoriously difficult to absorb: poorly soluble, rapidly metabolized, and cleared before much of it is absorbed.

This is why people take turmeric for months and feel nothing. It was never the turmeric. It was always how little of it gets into your bloodstream.

I built KURK with my best friend, medical doctor, and co-founder, Dr. Harrison Weisinger, whose work in research and medicine sits behind everything we make. Together, we spent six years on exactly this: developing a liquid micellar curcumin formulation designed to improve absorption—work we are now researching with Swansea Medical School over the next two years in our Knowledge Transfer Partnership. Micelles are tiny structures that form naturally during fat digestion. They can encapsulate fat-soluble compounds like curcumin and carry them across the gut wall into the bloodstream. A 2021 study by Flory and colleagues found micellar curcumin outperformed every other delivery format tested, including piperine-enhanced and fat-based formulations.

If you want to support recovery and comfort after thousands of rotational swings, being able to actually absorb what you take is the whole point.

Pain-free movement is earned over time and protected through the same consistency that builds a good golf game. That means looking after your body's everyday recovery as a habit, not a reaction to a bad round. The science of delivery matters as much as the quality of the ingredient. KURK is 100% plant-based, independently lab-tested and ISO certified, and KURK Sport carries Informed Sport certification, meaning every batch is third-party tested for banned substances.

The goal isn't simply more years on the course. It is more rounds in those years, played freely, without your body being the thing that decides when you stop.

About Trent Scanlen Trent Scanlen is co-founder of KURK Biosciences, the plant science company behind KURK's liquid micellar curcumin. A serial founder and athlete, he wrote KURK's original business plan during a period of serious illness, driven by a conviction that managing everyday inflammation is central to moving well, and living well, for longer. He and his co-founder, best friend and medical doctor, Dr Harrison Weisinger, have made a pact to live to 100, and built KURK as the practical expression of that goal.
