Viridian
Synerbio Daily
Synerbio Daily is an expert formulation comprising good gut bacteria with added ‘prebiotics’. The unique Prebiotic FS2-60 offers full-spectrum prebiotic oligosaccharide and plantderived inulin. FS2-60 is not digested but is utilised by the friendly flora to increase colonisation of Lactobacilli and the Bifidobacteria whilst reducing the foothold of unfriendly species.
The human gut is home to an immense population of bacteria. Some 100 trillion bacteria populate the human gut, a number that is 10 times greater than the number of cells in the human body. Because of the sheer size and importance of the gut bacteria, this microbial population can be viewed as a bacterial organ, about the size of your liver and just as important to support and protect.
Good for replenishing the digestive system after a bout of illness or medication whilst being gentle enough for daily support. We recommend taking alongside a multivitamin and an oil to form a foundation for good health.
Contains 100% active ingredients formulated by expert nutritionists with no artificial fillers and no nasties. Sourced according to Viridian’s strict ethical criteria including no animal testing, GMO or palm oil.
Just to make you aware we are currently updating our packaging so your supplement may look a little different. Please don't worry, it's the same goodness inside.

Our story
Fettle is a health store, reimagined.
Built in Holmfirth. Inspired by the wild.
We stock a wide range of curated products - carefully chosen foods, proven supplements, and low-impact home goods—with one aim: to help people feel well, live fully, and tread lightly.
We're guided by four principles:
Roam – move with purpose
Replenish – eat well, choose consciously
Rest – take space to recover
Renew – build resilience, inside and out
We favour quality over quantity, makers over mass production, and brands that back their ethics with action. You’ll find organic staples, therapeutic herbs, and sustainable tools for daily living—all under one roof.
Upstairs, our practitioner room offers tailored support, from nutrition to movement and mental clarity. Downstairs, you’ll find the starting point for your next chapter—whether that’s a new habit, a better meal, or a slower way of being.
Fettle is a basecamp for the everyday explorer.
Come as you are. Leave with what you need.
