Lisa and Alana Macfarlane,
The Gut Stuff

The Gut Stuff was born in 2017 by DJ's and Presenters Lisa and Alana Macfarlane (The Mac Twins), they've done everything from DJing at the Olympics, to presenting on the Brits red carpet, regular live radio shows for BBC 1xtra and Virgin Radio, creating their own DJ gaming live battle show and being the Official Love Island DJ's, but they can now add business women to that list and The Gut Stuff is their proudest venture to date.

Instead of taking over the decks, they're taking over the world with their mission of empowering gut health in everyone. It all started as twins are a great constant for medical research and Alana and Lisa became the “chief guinea pigs” for Prof Tim Spector and the Twin Research department at Kings College, where they discovered that despite having 100% the same DNA their guts have only 30/40% the same microbiota, which could explain why their bodies behave so differently – if they can’t be sold the same diet/lifestyle, no one can.

They made it their mission to bring the exciting information they were learning, to the masses (not just the “wellbeing aware” middle classes) and have since made www.thegutstuff.com the global millennial thought leader in the space. They knew as people devoured the information that they’d want to know which products to bring into their lives that were both efficacious, delicious and affordable, so they made their own. They have also written a best selling book packed with gut experts and  have a services workplace wellness arm to the business which has seen their team talk everywhere from Balfour Beatty construction site to Visa and Facebook.
