Launch of SlimBiome in leading US brand

OptiBiotix Health plc (AIM: OPTI), a life sciences business developing products which reduce hunger and food cravings, enhance the gut microbiome, and sweet fibres as healthy sugar substitutes announces the launch of a product containing its award-winning appetite reducing SlimBiome® in Hydroxycut, which markets itself as the No. 1 selling weight loss supplement brand in the United States of America ("USA").

This announcement confirms the launch of the first product under the brand name 'Hydroxycut Hunger Control', and follows on from the first order announcement on 15 April 2025. The product is sold through online outlets and retail outlets such as Walmart (as shown here), and product marketing includes two studies carried out by OptiBiotix which demonstrate reduction in hunger of 74% and 83%. Orders for a second product application have been received and expected to be launched later this year.

Hydroxycut is America's No.1 selling weight loss supplement brand and has sold over 100 million bottles of its product over the last two decades*. Hydroxycut products are sold online and via major retail outlets across the USA such as Walmart, Kroger, Target, GNC, Kmart, Albertsons, CVS Pharmacies and more. The brand has high customer awareness and in recent years has become increasingly known for its science backed products. The introduction of SlimBiome®, with its scientifically substantiated health claims of hunger control, helps to differentiate these products from other weight management products on the market.

This news is significant for the Company as it represents the inclusion of SlimBiome® in the products of one of the USA's most popular weight management brands which has led to orders totalling just under five metric tonnes for SlimBiome® in 2025. The Board believes that the opportunity has potential for future development and will provide further updates in due course.

Stephen O'Hara, CEO of OptiBiotix, commented: "We are pleased to announce the launch of products containing our patented award winning SlimBiome® in the USA. The Company has been working with Hydroxycut for almost two years to carry out human studies which allows the brand to make health claims of reductions in hunger of 74% and 83% in the USA. The launch with Hydroxycut substantiates the science behind SlimBiome and helps build the SlimBiome brand in consumer markets around the world. This is another example of the Company launching products with well-known brands in key international markets which if successful, individually and collectively, have the potential to make a significant contribution to future sales growth and shareholder value."
