Champion boxer Katie Taylor has teamed up with Irish wellness company SiSú to launch Fizzique, a low-calorie, low-sugar soda line available in four flavours that is high in fibre and fortified with magnesium and Vitamin D. The partnership leverages SiSú’s reputation in better-for-you drinks and expands both brands’ product portfolios—Taylor’s first functional drink offering and SiSú’s continued push into new formats to capture health-conscious consumers.
Katie Taylor Launches Fizzique Soda In Partnership With SiSú Apr 28, 2026 Katie Taylor has today announced the launch of Fizzique, co-created with well-known Irish wellness brand SiSú. Available in four flavours, the new soda is a better-for-you alternative to classic fizzy drinks, in that it is high in fibre, infused with magnesium and Vitamin D, and made with juices and natural flavourings, as well as being low in sugar and calories. Popular wellness brand SiSú was founded by Brian and Fiona McGann – and is now run by their daughter, Aisling McGann – with the simple belief that what you drink every day should do something good for your body. The Irish wellness brand has spent years building its name in the better-for-you drinks category, with products including kombucha, plant-based milks, cold-pressed juices and functional shots. SiSú has earned 12 Great Taste Awards since its founding, and yet its philosophy has remained the same: premium quality, premium taste. Collaboration This philosophy is what caught Taylor’s attention, as years before the collaboration, the champion boxer followed the brand with interest. When speaking with Brian McGann about better-for-you drinks, she expressed frustration at not being able to find an enjoyable soda that would not compromise her training or her body. That conversation led to what would ultimately become Fizzique. Taylor joined up with SiSú to build a partnership, with the beginnings of this relationship seen in February of this year, when they launched a Prebiotic Overnight Oats range together. While that was SiSú’s first foray into functional foods, Fizzique is Taylor’s first go at functional drinks. The drink comes in Zest Lemon & Ginger, Passionfruit & Yuzu, Watermelon Lime & Mint, and Blood Orange and Mango flavours, all with the same benefits. Commenting on the launch, Taylor said, “Just like we changed minds about women and boxing, with Fizzique we’re going to change minds about soda and health. “It’s a game-changer, it’s ambitious, and I love it.” Brian McGann added, “We’ve spent years building products that people can trust, with ingredients that do what they say and taste good enough that people actually want them. “Fizzique is arguably the most exciting thing we’ve ever made. “Fizzique is the soda that supports every body.” To learn more about Fizzique visit fizziquedrinks.com and follow Fizzique Drinks on Instagram.
