Overview
Blis Technologies is a New Zealand biotechnology company headquartered in Dunedin and focused on probiotics for the mouth and throat. Its core technology is based on selected strains of Streptococcus salivarius, a bacterium associated with the human oral microbiome. The company has developed branded probiotic products intended to support oral, throat and breath-related health, distributing them in formats such as lozenges, powders and chewing gum. The company was established in 2000 by microbiologist John Tagg, who left an academic position at the University of Otago in August of that year to commercialize research into bacteria and their potential effects on human health and hygiene. Tagg's interest in the subject was influenced by his experience with rheumatic fever during childhood and his subsequent efforts to investigate ways of countering disease-related bacteria. Blis Technologies was formed to translate this research into consumer health products. Its first major commercial product was ThroatGuard, introduced in 2002 and formulated with the BLIS K12 strain. The product helped establish the company's focus on oral and throat probiotics. The BLIS K12 platform was later adapted into additional products, including ToddlerProtect, a powder intended for children and infants, TravelGuard for travelers, and FreshBreath, introduced in 2005 for breath-freshness applications. These products extended the company's use of the same underlying probiotic research across different consumer needs and delivery formats. Blis Technologies subsequently expanded beyond BLIS K12 with BLIS M18, a Streptococcus salivarius strain developed for oral-care applications associated with tooth decay and periodontal health. Introduced to the New Zealand market in 2012 under the HealthyTeeth brand, BLIS M18 became the company's second major proprietary probiotic platform. The company has described clinical research as supporting the strain's role in promoting oral-cavity health, although individual product claims and regulatory treatment vary by market. The company's proprietary bacterial strains have also been protected through intellectual property. Blis Technologies has been associated with a world-first patent covering its selected oral-bacteria strain. In 2011, BLIS K12 received Generally Recognized as Safe status in the United States, allowing its use as a food additive under the relevant regulatory framework. The company has marketed its products internationally, while retaining its operational base in New Zealand. Blis Technologies has received recognition for its commercial and innovation activities, including a 2010 Frost & Sullivan Global Entrepreneurship award and Deloitte's recognition of the company as New Zealand's Fastest Growing Mature Business in 2016. Its public-company identity and international distribution distinguish it from a single-product supplement label: Blis Technologies operates as a specialist probiotic developer with a portfolio centered on oral microbiology, strain research and consumer health formulations.
History
Blis Technologies emerged from microbiological research conducted by John Tagg, a University of Otago microbiologist whose work examined bacteria found in diets and their possible effects on personal hygiene and human health. Tagg's interest in disease prevention was shaped in part by having contracted rheumatic fever at the age of 12. As a young scientist, he pursued ways of understanding and countering bacteria associated with illness. In August 2000, Tagg left his academic position at the University of Otago and established Blis Technologies in Dunedin. The company's purpose was to commercialize selected beneficial bacteria, particularly strains of Streptococcus salivarius associated with the mouth and throat. Rather than developing conventional pharmaceutical medicines, Blis Technologies built a biotechnology and consumer-health business around proprietary probiotic strains, intellectual property and branded delivery formats. The company's first significant commercial product was ThroatGuard, launched in 2002 with the BLIS K12 strain. This product established the company's central market proposition: using an oral probiotic in a convenient consumer format for throat-related health. The BLIS K12 platform was later used in products aimed at different audiences and occasions. ToddlerProtect was developed as a powder suitable for children and infants, while TravelGuard was introduced in 2006 for travelers exposed to airborne germs. FreshBreath, announced in September 2005, applied the same broad oral-health concept to breath freshness. Blis Technologies continued to broaden its science and product portfolio through BLIS M18, another Streptococcus salivarius strain. The strain was developed for oral-care applications involving bacteria associated with tooth decay and periodontal disease. It entered the New Zealand market in October 2012 under the HealthyTeeth brand. The company's materials and referenced clinical work have presented BLIS M18 as a probiotic intended to promote oral-cavity health. Regulatory and intellectual-property developments helped support the company's commercialization strategy. Blis Technologies has been associated with a world-first patent for its selected oral-bacteria strain. In 2011, BLIS K12 received U.S. Generally Recognized as Safe status, enabling its use as a food additive under the relevant U.S. framework. The company has sold products internationally in forms including lozenges, powders, gum and other formats, while remaining headquartered in Dunedin. The company has also received external recognition. Its oral-probiotic innovation and entrepreneurship were recognized with a 2010 Frost & Sullivan Global Entrepreneurship award. Deloitte later named Blis Technologies New Zealand's Fastest Growing Mature Business for 2016. Blis Technologies is publicly listed on the New Zealand Stock Exchange and has developed from a university-linked biotechnology venture into an international specialist in oral and throat probiotic products.
