BioHarvest Sciences Announces that VINIA is Now the No.1 Resveratrol Polyphenol Brand in the United States

VINIA's leadership position in the market validates its superior arterial dilation and blood flow performance as well as BioHarvest's Botanical Synthesis platform technology

Vancouver, British Columbia and Rehovot, Israel--(Newsfile Corp. - March 26, 2026) - BioHarvest Sciences Inc. (NASDAQ:BHST) (FSE: 8MV0) ("BioHarvest" or the "Company"), a biotechnology company pioneering its proprietary Botanical Synthesis™ platform, today announced that its VINIA^® brand has achieved the position of the #1 Resveratrol Polyphenol Nutraceutical Brand in the United States*.

VINIA's leadership position is driven by its clinically demonstrated ability to increase arterial dilation, improving blood flow and enabling enhanced delivery of oxygen and nutrients throughout the body. This mechanism of action addresses what many medical experts increasingly recognize as one of the most foundational elements of human health and performance: efficient blood flow and oxygen delivery.

"Achieving the No.1 position in the U.S. resveratrol category in less than five years reflects both the strength of VINIA and the power of our Botanical Synthesis platform technology," said Ilan Sobel, Chief Executive Officer of BioHarvest Sciences. "VINIA's clinically demonstrated ability to increase arterial dilation, providing blood flow benefits, combined with its unique protected plant-cell delivery system, create a differentiated product that consumers are increasingly recognizing and adopting. The strength of VINIA as a subscription base product has enabled us to build unique and credible e-commerce platform capabilities with our VINIA.com website which accounts for approximately 80% of VINIA US revenue."

VINIA's leading position in the market reflects the continued growth of the Company's direct-to-consumer business, which generated more than $30 million in U.S. revenue for full-year 2025 and approximately $85 million in global cumulative revenue to date. Less than five years after entering the U.S. market, VINIA has achieved category leadership, with more than 85,000 active users of VINIA wellness products across the United States and Israel.

Dr. Edward Maristany, member of the BioHarvest Scientific Advisory Board and Functional Medicine Physician, commented "VINIA is a life-changing compound — which has impressive solubility, bioavailability and efficacy qualities given the unique structure of the compound and the protective cell envelope which also shields the compound from degradation as it moves through our body. I have over 200 patients who have consistently taken VINIA for more than a year. The improvements in their quality of life derived from VINIA's clinically proven ability to increase arterial dilation have been significant. The effects of improved blood flow have been substantial in driving improvements in my patients' physical energy and mental alertness."

Botanical Synthesis- The Technology Behind the VINIA Brand

VINIA is built around a proprietary red grape composition featuring piceid resveratrol as its hero molecule, combined with a complex of naturally occurring grape polyphenols including catechin, quercetin, anthocyanins, and tannins. These molecules work synergistically to support arterial function and vascular performance.

The effectiveness of this composition is further enhanced by BioHarvest's proprietary Botanical Synthesis technology, which preserves the molecules inside their natural plant cell environment. This protective cell envelope safeguards the phytonutrients from degradation during production through to ingestion as well as during passage through the stomach's acidic environment, helping preserve efficacy.

Unlike traditional plant extracts that isolate individual molecules, Botanical Synthesis delivers a naturally derived, patentable, non-GMO composition that preserves the original molecular conformation of phytonutrients within their native cellular environment — creating a differentiated delivery system for plant-based compounds.

With VINIA, BioHarvest's Botanical Synthesis platform magnifies the piceid resveratrol levels by up to 100x compared to what is naturally found in red grapes, while maintaining the synergy of the full polyphenol complex.

Due to VINIA's vasodilation benefits and ability to improve blood flow, the Company views VINIA as a foundational compound to be added to other synergistic molecules to create innovative and effective nutraceutical products, further strengthening BioHarvest's leadership in plant-based health solutions.

*This #1 Resveratrol Polyphenol brand position is based on comparing VINIA® 2025 annual sales revenue in the US with the estimated market size for Resveratrol Nutritional Supplements, utilizing NielsonIQ (NIQ) 2025 market projections for Resveratrol Nutritional Supplements and Beverages, together with Amazon sales data projections for Resveratrol Nutritional Supplements, which represent the large majority of the Total Resveratrol Polyphenol Only Market.
