A note from Jason

I've spent my career building athletes — the physical engine underneath the tennis. Performance is never one big thing; it's a hundred small ones done daily. Here are the eight reasons I recommend IM8.

Clinicians' Choice
01Where it started

I use the product every single day.

In performance coaching, the scoreboard tells you nothing about why. Matches are won in the months of preparation nobody sees, and I can't control anything on match day except how ready my athlete arrives. What I can control is how I arrive: rested, fuelled, sharp. That part is on me.

So I started treating my daily nutrition as seriously as I treat every detail of an athlete's preparation, because both are inputs I actually own. IM8 became one of them — one daily drink that covers what my body needs, so I can hold myself to the same standard I ask of the athletes I work with.

“I've spent my career building athletes — the physical engine underneath the tennis.”

90 daysthe daily routine I rely on
And for you

You don’t need a professional career to start. You need one decision and ninety days of showing up.

02The long game

I'm building a body that has to last.

My whole profession is the long game: building bodies that peak today without breaking tomorrow. I apply the same principle to myself. IM8 is part of how I practise what I coach.

And for you

You don’t need a professional career to invest in the long run. The small things you control every day quietly add up.

03I can't afford to get this wrong

It's NSF Certified for Sport.

I build training and recovery programmes for professional athletes who are drug-tested all year round. The athletes I work with are subject to anti-doping testing, and one contaminated supplement could end a career I've helped build. I don't guess about what goes into their bodies — or mine. IM8 is NSF Certified for Sport and WADA-compliant. Every batch is screened against the strictest standards there are. For me, that's not a marketing line; it's the one reason I'd ever put my name on something I actually recommend.

And for you

If it’s clean enough for drug-tested professional sport, it’s clean enough for you — and for your family.

04Simplicity that lasts

It replaced a cabinet full of bottles.

A pile of supplement bottles versus one IM8 sachet and a glass of water

I used to travel with a pharmacy. Different pills for energy, for gut health, for immunity, for recovery — half of which I'd forget to take anyway. It was a mess. IM8 is one sachet. 90+ ingredients, nine organ systems, one glass of water in the morning. It took the most important habit in my day and made it the easiest one.

And for you

Nobody — athlete or not — sticks with a routine that needs 16 bottles. Simple is what actually lasts.

05How I feel

Steady energy day after day.

Athletes competing in a gym training session

In tennis, the matches that get away are lost in the third hour, when energy dips — and a coach who fades in the third hour of a training day is no use to anyone. What I want on court — and on a long working day away from it — is energy that's steady rather than spiky, so it's still there in the moment it matters most. That's what IM8 supports: clean, sustained energy that holds through the hardest stretch instead of crashing right when it counts.

And for you

A long race or a long day — steady energy that lasts will always beat a spike and a crash.

06The one constant

It travels everywhere I do.

Athlete training with battle ropes

I go where the athletes go: pre-season blocks, tour swings, championships — a season lived out of a suitcase. So much of this job is staying in motion and still being ready when the session starts. IM8 is one of the few things that never changes. A sachet goes in my bag and the routine comes with me — Melbourne, Miami, Paris, it doesn't matter. It's the constant that keeps my body feeling like mine, whatever time zone I wake up in.

And for you

You don't have to cross time zones to know how much one reliable habit can hold a chaotic week together.

07Where matches are won

It's how I recover and sleep.

The tour grinds everyone down — players and staff alike — with early mornings, late nights and constant travel. Then you do it all again the next morning. The ones who last aren't just the hardest workers; they're the ones who recover well enough to do it again. IM8 is part of how I recover and how I sleep. Better sleep and a faster bounce-back is where the next result is quietly won — and recovery is the half of this sport that nobody at the top is allowed to skip.

And for you

Whether you’re chasing a title or chasing your week, you’re only ever as
good as how well you recover.

08What I stand behind

I put my name behind it.

I'm careful about where I attach my name. I recommend IM8 because I believe in where it's going: co-founded with David Beckham, built with a world-class scientific team, and held to a standard I'd actually stake my reputation on. You don't put your name behind something you don't use. I use it every single day.

This is for you, too

You don't have to be a professional to make daily nutrition a priority

My life looks nothing like yours, and that’s the point. The schedule, the travel, the pressure — different. But what IM8 actually does is universal: steady energy, an easier routine, a body that recovers. You don’t need my career to feel that. You just need to start.

If you're an everyday person

  • Trade ten forgotten bottles for one morning ritual.
  • Steady energy that gets you through the day — and the evening with your family.
  • Clean enough that you never have to wonder what's in it.

If you're an active individual

  • The same recovery and gut support I rely on between sessions.
  • NSF Certified for Sport — train and compete with total confidence.
  • One constant that travels with you to every race, gym, and trip.
