Vitamin B12 1000ug (High Potency)
Vitamin B12 is an essential nutrient which has been proven to help reduce tiredness and fatigue and contributes to normal function of the immune system. Essential nutrients cannot be made by the body, but instead must come from diet or supplementation. Foods that are naturally rich in B12 include meat, fish, dairy products and some fortified foods. This supplement is an effective way to boost B12 levels, especially for those following a vegan or vegetarian diet.
This high-strength formulation provides active vitamin B12 as both methylcobalamin and adenosylcobalamin. These 2 different active forms work synergistically, playing vital roles in energy production, healthy blood cell formation and functioning of the nervous system. Each capsule provides 1000μg and is as effective as sublingual B12.
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.
