SiSú was founded on a bold principle: that daily beverages should offer real benefits for your health. Established by Brian and Fiona McGann, and now led by their daughter Aisling McGann, this Irish wellness brand has spent years becoming synonymous with quality in better-for-you drinks, including plant-based milks, kombucha, cold-pressed juices, and functional shots. With twelve Great Taste Awards to their name, their commitment to superior quality and taste remains unwavering.
Katie Taylor’s interest in SiSú was piqued by this philosophy. Long before any business discussions began, she admired the brand’s progress. As a world champion athlete, she understood the value of nutrition. In conversations with Brian, she expressed a recurring challenge: finding a soda she truly enjoyed that wouldn’t hinder her training or overall health.
This challenge became the foundation of their collaboration.

Pic: Marc O’SullivanWhen discussions between Katie and SiSú intensified a year ago, the focus wasn’t on mere branding. It was about creating something genuinely beneficial that addressed a real need. The goal was to produce a drink that contained fiber, was low in sugar and calories, and free of artificial sweeteners or additives, while still being delicious enough to compete with traditional sodas.
SiSú recognized the importance of providing a compelling alternative, one that encouraged people to make healthier choices rather than simply asking them to give up their beloved sodas. Katie shared this vision; having spent her career challenging perceptions, she believed they could spark a similar transformation with this beverage.
Thus, rather than a sponsorship deal, they formed a true partnership. Katie’s involvement was about guiding the product’s development from the ground up.
The end product is Fizzique: available in four exciting flavors and rich in fiber, infused with magnesium and Vitamin D, and made from natural juices. This new soda embodies the collaboration between a world champion with a vision and a family-run business equipped with the expertise to bring it to life.
