MicroSalt Launches MicroSalt Fibre

A patented, dual action ingredient technology that combines MicroSalt's established low sodium salt with functional fibre

MicroSalt (AIM: SALT), a leading manufacturer of full-flavour natural salt with approximately 50% less sodium, is delighted to announce the launch of MicroSalt Fibre, extending its patented technology into a dual function solution that enables both sodium reduction and functional fibre within a single ingredient.

MicroSalt Fibre is a patented, dual action ingredient technology that combines MicroSalt's established low sodium salt with functional fibre. MicroSalt patented technology covers the use of a broad range of carriers and a consistent production process, meaning the same proven know-how and controls behind MicroSalt are applied to MicroSalt Fibre. The product enables manufacturers to address two key nutritional objectives simultaneously reducing sodium content and increasing fibre, while maintaining flavour, texture, and operational efficiency. This launch reflects a broader shift in the food industry, where reformulation is no longer focused on single nutrient reduction, but on delivering multiple nutritional improvements at the same time, without compromising product performance.

According to Fortune Business Insights, the global dietary fibre market was valued at $9.6 billion in 2025. The market is projected to grow from $10.6 billion in 2026 to $22.0 billion by 2034, exhibiting a CAGR of 9.63% during the forecast period.¹

Additionally, as international demand grows for tighter regulation of sodium consumption, including the expansion of High Fat, Sugar and Salt ("HFSS") regulations in the UK, the Company believes that technology capable of both reducing sodium and improving product health profiles through increased fibre content positions MicroSalt to further expand its reach and strengthen its market share. MicroSalt Fibre has been formulated to support these evolving global requirements through a single-ingredient solution that can be deployed across multiple product applications.

MicroSalt Fibre was developed in response to growing demand for functional carriers to replace or enhance "empty calorie" carriers such as maltodextrin, driven by evolving consumer preferences and the rise of GLP-1-related nutritional gaps. Suitable for use across a range of food categories, including snacks, baked goods and prepared meals, the technology has been designed for seamless integration into existing manufacturing processes, enabling rapid deployment at industrial scale without requiring reformulation complexity or changes to established production systems.

MicroSalt enjoys tailwinds resulting from increased regulation and as regulatory frameworks evolve and front of pack labelling systems become more stringent, sodium reduction and fibre enhancement are emerging as two of the most immediate and actionable levers available to manufacturers. MicroSalt is not only reducing sodium, but also enabling a new standard for practical, scalable food reformulation.

Rick Guiney, Chief Executive Officer of MicroSalt, commented: "We are delighted to launch our latest innovative product, MicroSalt Fibre, which marks an important evolutionary step in our technology. The industry is moving beyond single nutrient reformulation, and manufacturers are increasingly looking for solutions that deliver multiple health benefits without the added complexity. MicroSalt Fibre responds directly to this need, enabling both sodium reduction and fibre fortification within a single ingredient, while maintaining taste, texture and operational efficiency. This is a natural extension of our mission to support healthier food systems at scale."

About MicroSalt

MicroSalt is disrupting the global salt market with its patented, full-flavour, low-sodium salt designed for both food manufacturers and consumers. Using proprietary micron-sized particles, MicroSalt delivers the same salty taste as traditional salt with approximately 50% less sodium, offering a scalable solution to one of the world's most pressing health challenges. Year to date through 2025, MicroSalt has contributed to more than 634M servings made healthier.

Excess sodium consumption is a leading contributor to cardiovascular disease, the world's number one cause of death. The World Health Organisation has targeted a 30% reduction in global sodium intake by 2025, a shift projected to save seven million lives by 2030. The economic case is equally compelling: in the UK alone, cardiovascular disease costs £19 billion annually, and reducing average daily salt intake by just one gram could save over 4,000 lives and £288 million each year. 

Operational since 2018, MicroSalt has established a defensible IP portfolio, holding a granted US patent and 14 pending applications worldwide. These protections create significant barriers to entry in a market expected to grow exponentially as regulation and consumer demand accelerate.

MicroSalt is ideally positioned for scale and market leadership, with clear pathways into food manufacturing, consumer channels, and ultimately the broader £10+ billion global salt market. MicroSalt is more than a healthier alternative-it is a disruptive, category-defining solution poised to deliver significant commercial and societal impact.
