Viridian
Viridikid Synerbio Powder
Viridikid Synerbio Powder is an expert formulation comprising four strains of good gut bacteria (commonly known as probiotics) with added prebiotics and vitamin C. The unique prebiotic FS2-60 offers full-spectrum prebiotic fructo oligosaccharides and plant-derived 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.
Synerbio Children's Powder also features buffered Vitamin C for a gentle delivery of this key nutrient. Vitamin C plays an essential role in numerous areas of children's health, as it contributes to the normal function of bones, cartilage, skin, gums and teeth. Vitamin C also aids in the maintenance of the immune system and contributes to normal psychological function.
Pleasant tasting and dairy-free, this is a great way to deliver high-quality support to keep little tummies happy. Good for replenishing the digestive system after a bout of illness or medication whilst being gentle enough for daily support. Can be taken straight from the spoon, added to drinks or mixed into cold foods. A 1 gram measuring scoop is provided in the jar.
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.

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.
