1N is a pioneering nicotine brand, launching in the UK in 2026, with its first products (soft and hard lozenges), designed to bring greater clarity and integrity to the category long shaped by its association with smoking. By focusing on transparent ingredients, intentional formulation, and non-combustible delivery, the brand aims to offer consumers a more considered alternative.

1N was founded in Berlin by Terry Seal, a biohacker herself, whose journey was driven by personal health challenges and frustration with existing options available on the market.

“Living with conditions like perimenopause and endometriosis pushed me to look beyond conventional approaches to pain management and stress,” she says. “I became interested in emerging research on energy regulation and cognitive performance, which led me to the wider discussions around nicotine, including both its potential and well-established risks.”

As she explored the space further, getting inspiration from the work of the biohacking community, Terry identified a gap in the market for nicotine users seeking low-strength, non-combustible formats. “It was surprisingly difficult to find nicotine products that were upfront with their ingredients, transparently sourced, and designed with intention. Most options felt flawed or outdated, and that didn’t align with how modern consumers think about what they put in their bodies.”

With more than 20 years of consumer packaged goods experience and a passion for formulation, Terry set out to develop a nicotine product rooted in higher standards of conception, extensive testing, and ingredient transparency. 1N products are formulated without sucralose, aspartame, or artificial colourings, reflecting a growing demand for high-quality products.

Today, 1N’s mission is to offer a more transparent and intentional approach to nicotine, especially at a time when consumers are increasingly scrutinising ingredients, sourcing, and delivery methods.

Being a female founder in a male-dominated regulated space

However, building a brand in a regulated space comes with its own set of challenges, particularly as a female founder.

“Launching a nicotine product means navigating complex compliance requirements and ongoing regulatory scrutiny,” says Terry. “On top of that, being a woman in a traditionally male-dominated can shape perceptions of credibility. In the UK, only around 13% of founders are women, and the gap becomes even more visible in sectors like this.”

For Terry, 1N is not only about changing perceptions around nicotine products, but also about representation and standards.

“We want to show that female founders can build rigorous, compliant, and commercially viable brands in highly regulated spaces. If we can help challenge assumptions about both product design and who gets to innovate in this category, then we’re doing something meaningful.”
