SupaG Health Pty Ltd founder Nick Diamantopoulos will unveil new garlic products at the renowned Gilroy Garlic Festival this July, following the publication of peer-reviewed studies demonstrating that certain garlic varieties likely possess significant antiviral properties, the company announced.
The findings, published in scientific journals including the Journal of Functional Foods (2024) and JSFA Reports (2026), showed that certain garlic varieties demonstrated strong activity in laboratory studies against respiratory viruses including SARS-CoV-2 and Influenza A. The in vitro studies found that only a small specific subset of garlic, regardless of growing location, exhibited meaningful antiviral activity, and that certain garlic extracts were able to impede viral entry into host cells. Notably, the same cultivars demonstrated activity across both COVID and Influenza A studies, suggesting the properties may be linked to the variety itself rather than the growing location.
"These findings fundamentally change the way we should think about garlic," said Diamantopoulos. "For generations, garlic has been viewed as a natural remedy, however our research indicates that not all garlic is equal for health benefits, just as not all garlic is equal for nutrition and flavor. Different varieties possess different biochemical and functional properties, and in identifying these cultivars, we can open the door to entirely new categories of garlic health products."
The research program draws on more than 30 years of collection, breeding, and analysis, involving more than 300 garlic varieties sourced from around the world. Diamantopoulos believes the discoveries may represent one of the most historically significant scientific developments in the garlic industry. "The future of garlic nutraceuticals will not be commodity-based. It will be health-specific," he said. "We are moving from generic garlic products towards identified cultivars with targeted functional properties, proprietary formulations, traceable genetics and evidence-based health positioning."
The company is introducing a premium garlic supplement with a proprietary ingredient focused on specific formulations supported by peer-reviewed scientific research. SupaG Health is actively pursuing distribution partnerships, nutraceutical and pharmaceutical collaborations, retail expansion opportunities, and further product development based on its proprietary research.
According to the published research, biological activity likely depends on the underlying garlic cultivar, extraction methods, formulation techniques, and processing controls. This creates opportunities to develop intellectual property around identified cultivars and proprietary formulations for the nutraceutical, functional food, and pharma sectors.
"This research establishes a scientific foundation for a new premium category within the health industry," Diamantopoulos said. "Gilroy is the ideal place to begin that conversation with the world."
Throughout the festival, Diamantopoulos and the SupaGarlic team will be available at the Gilroy Garlic Festival to discuss the published research, commercial development plans, and opportunities for strategic partnerships, distribution, and clinical research partners.
