Nick Butter, the world-record-setting marathon runner who’s famously conquered every country on Earth, has joined forces with the government-backed British science company, SmarterNaturally, to bring a unique super-broccoli soup to more men.
Renowned for raising millions in the fight against prostate cancer, Butter says he’s found a natural way to boost performance while also taking care of long-term health—and he’s determined to share that discovery with fellow athletes and men everywhere.
If you haven’t heard of Nick Butter before, he’s the only person known to have run a marathon in every country in the world, smashing eleven world records in the process.
But as remarkable as his physical feats may be, he views his real success as the funds and awareness he’s generated for prostate cancer charities.
His personal connection to the cause was sparked when close friends were affected by the disease, and he’s been pounding the pavement in its name ever since.
Now, Butter is endorsing SmarterNaturally’s super-broccoli, which contains a strain called GRextra that packs five times more sulforaphane than typical broccoli.
It’s a powerhouse ingredient thought to help repair and maintain a healthy metabolism—a major plus for athletes looking to train harder, recover faster, and stay at the top of their game.
More importantly, there’s growing evidence that sulforaphane supports prostate health and may even reduce the risk of certain cancers.
“Broccoli has long been favoured by both prostate cancer clinicians and athletes the world over. Having a super-broccoli that can support health as well as provide a potential edge for athletes is a win, win.” Said Nick.
“I am very keen to raise awareness about Prostate Cancer and continue to raise money for Prostate charities, through sport and the work I do, and so working with a company like SmarterNaturally which shares this goal and can simultaneously support my running career is a dream come true.”
With his next ambitious—yet still secret—challenge on the horizon, Butter has been incorporating SmarterNaturally’s broccoli-based products into his training routine.
He believes that fuelling his body with high levels of sulforaphane can make a tangible difference to his performance.
Decades of research went into creating SmarterNaturally’s GRextra super-broccoli, which delivers five times more sulforaphane than standard varieties—helping boost energy production, speed recovery, and potentially lower the risk of prostate cancer. It’s a two-pronged benefit: improved fitness today and a healthier tomorrow.
Nick Butter said: “I’ve always loved broccoli, but I never realised that it contains active ingredients that help your cells to grow and repair themselves.
When you’re pushing the boundaries of what’s possible, every choice matters, so a super-strength broccoli supplement that supports not only my long-term health, could reduce my prostate cancer risk as well as my training is a no-brainer.”
Meanwhile, SmarterNaturally offers two main products—an instant “supersoup” and a 250g pouch of broccoli powder called BrocAffex.
Both are fully sport-legal, easy to use, and pack a punch with just one weekly serving, making them convenient for busy athletes or anyone looking to supercharge their metabolism.
Nick said: “They are such simple products to use, it’s affordable and slots into my health and fitness programme really easily. The science behind the product and its effect on metabolic health is also interesting, with the potential not only to improve my performance but also to support my recovery and help to protect my joints and long-term health, providing a range of benefits all in one.”
While this super-broccoli is getting particular attention for its prostate health benefits, women and men alike can reap the rewards of better metabolic support—potentially aiding everything from endurance and power to joint and cognitive health.
If you’re looking for a natural edge in sport or everyday wellness, Nick Butter’s new favourite super-broccoli might just be the green boost you’ve been waiting for.
