8 reasons why I chose to be IM8's global ambassador and shareholder

I'll be honest — I didn't go looking for a supplement. My performance coach, Jason Stacy, did. He's the person who sees me at 6am and at 11pm, who knows exactly how my body responds to a heavy training block. One morning he put IM8 in front of me and said: "Just give me three months. Take it every single day and tell me what you feel."

I'm naturally a little skeptical. I've tried things that promised the world and did nothing. But I trust Jason more than almost anyone, so I committed. Three months. No skipping, no excuses. By the end of it, it wasn't a question anymore — it had become part of who I am every morning. I haven't missed a day since.

This was never just my thing. Look around my box at a tournament and you'll see the same drink in everyone's hands. Andrei, Anton, Jason, Helen, Max — my coaches, my physios, the people who keep me standing — they all take it daily, and they all feel it.

When the people who obsess over performance for a living quietly choose the same thing for themselves, away from the cameras, that tells you everything you need to know.

As the world No. 1, I get tested. A lot. One contaminated supplement can end a career — so I'm not allowed to guess what goes into my body, and honestly, I wouldn't want to.

IM8 is NSF Certified for Sport and WADA-compliant. Every single batch is tested against the strictest standards that exist. I don't take that label lightly. It is the one reason I would ever put my name on something.

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.

The first thing I noticed wasn't dramatic, it was steady. No 3pm crash. No leaning on caffeine just to survive a second session.

Good gut health and real, sustained energy that lasts through three hours on court and the press conference after it. Once you feel that, you don't want to give it back.

I'm in a different country almost every week — different time zones, different food, hotel rooms that all start to look the same. So much of my life changes constantly.

IM8 is one of the few things that doesn't. It's the constant in my bag, the thing that keeps my body feeling like mine no matter where in the world I wake up.

People see the matches. They don't see the recovery that makes the next one possible. Better sleep, faster bounce-back between sessions — that's where matches are actually won.

IM8 became part of how I recover, and recovery is the part of performance that nobody is allowed to skip.

There's a real difference between lending your name to something and betting on it. I became a shareholder in IM8 because I believe in where it's going — co-founded with David Beckham, built with a world-class scientific team, held to a standard I'd stake my own career on.

You don't put your own money behind something you don't actually use. I use it every single day — and now I own a piece of it too.
