Gutology, the oral health startup behind a gut-friendly toothpaste, has raised £1.8 million to support international growth.

The business was founded by former radio presenter and Gutology Podcast host Ollie Gallant, who launched the brand after years of digestive health issues led him to focus on the role of “good bacteria” in overall wellbeing.

Its Oral Biome+ toothpaste is designed to support the mouth’s microbiome and is now a top 10 product on Amazon UK, as well as the best-selling toothpaste at Planet Organic.

The funding, from Mercia Ventures-backed Midlands Engine Investment Fund II alongside Active Partners and angel investors, will help the London-based business expand into the US and Germany, build new retail partnerships and increase clinical research as it grows its wider oral care range.
