When The Gut Stuff founders (twins Lisa and Alana) participated in a study as part of Twins UK research they discovered that despite having 100% of the same DNA, their guts shared only 30–40% of the same microbiota. They began a mission to understand how and why this was and to take their learning to the masses. They found that the world of gut health was seen as a middle class luxury full of expensive products and inaccessible messaging. They set about to change this with The Gut Stuff through a combination of education and products.
