Bio&Me, the gut health brand co-founded by Dr Megan Rossi (The Gut Health Doctor), is set to disrupt the dairy aisle with the launch of a category-first functional kefir range.

Designed to bridge the gap between traditional fermented drinks and the booming demand for targeted health benefits, the new four-strong line-up moves beyond basic gut health to offer specific advantages like immunity defence, natural energy, and high protein/fibre.

The launch comes as Bio&Me reports a stellar performance year, with retail sales surpassing £22 million — a 52% year-on-year increase. With its kefir yogurts already growing at 60%, the brand is now looking to raise the bar in the drinks category by providing science-led innovation that addresses the top drivers for health-conscious shoppers.

Unlike many competitors that rely on added sugars or thickeners, Bio&Me says its range contains 18 different culture strains (including the highly studied LGG and BB12) and over 100 billion active cultures — the highest count currently on the market.  

The range is EFSA-approved as “Good For Your Gut” and is naturally high in protein, B12, B2, calcium, and phosphorus. Each flavour has been curated to align with a specific functional need:  

  • Berry & Acai: gut health + immunity
  • Matcha Vanilla: gut health + natural energy
  • Cocoa: gut health + protein & fibre
  • Mango & Peach: gut health + protein & fibre

Dr Megan Rossi emphasised that the mission was to eliminate the “nasties” often found in commercial kefir.

“Many kefir drinks on the market — even those labelled as ‘gut healthy’ — often contain added sugars, thickeners or artificial ingredients,” says Dr Rossi. “We wanted to create a best-in-class range that offers genuine functionality, making it easy for shoppers to support their gut health through simple, tasty, everyday choices.”  

Jon Walsh, CEO and co-founder, added: “These category-first launches deliver true science-led innovation… giving shoppers clearer reasons to buy and providing retailers with a strong platform to recruit new consumers.”
