Susosu Water Expands to Giant Foods Stores Across Mid-Atlantic

Susosu Water, a functional beverage company based in Washington, D.C., is expanding its retail footprint this spring with the launch of its hydrogen-infused mineral water in Giant Foods stores across the Mid-Atlantic. The rollout marks a meaningful step forward in the company’s steady, deliberate growth, bringing its product into one of the region’s most established grocery chains.

Founded in 2018 by Jheen Oh and Nadia Lizarazu, Susosu began as a personal pursuit. The founders became interested in hydrogen-infused water after experiencing its effects during travel in South Korea. They began researching the science behind molecular hydrogen, which has been studied for its antioxidant potential and its possible role in reducing inflammation and improving recovery. Encouraged by the emerging evidence and the lack of hydrogen water options in the U.S. market, Oh and Lizarazu decided to create a product that was both accessible and rooted in research.

Susosu sources its mineral water from a natural spring located 400 feet underground. The water is naturally rich in minerals, including potassium, selenium, zinc, calcium, magnesium, and silica. Using Korean technology, the company infuses the water with molecular hydrogen while maintaining its integrity through specialized packaging designed to preserve hydrogen content until consumption. The result is a product positioned within the growing category of functional beverages, offering a point of differentiation through both its formulation and its packaging.

The company’s participation in Union Kitchen’s Accelerator in 2022 provided a structure to refine its brand and scale operations. Through Union Kitchen, Susosu developed a go-to-market strategy, secured co-packing capabilities, and leveraged access to distribution channels. These steps enabled the company to expand into more than 500 retail locations, including placements with GoPuff, Foxtrot, and Whole Foods Market.

The new placement in Giant Foods is especially meaningful for Lizarazu, who once worked at a Giant store in her hometown. Returning as a supplier reflects the evolution of her role in the food industry, and highlights Susosu’s progress from an early-stage startup to a company with growing regional reach. The partnership with Giant also aligns with Susosu’s goal to meet customers where they shop and to introduce a wider audience to hydrogen-infused water.

Susosu’s growth reflects the broader opportunities available to entrepreneurs who are building food and beverage companies with a clear focus, thoughtful execution, and the right operational support. For those currently selling at farmers markets or in a few independent stores, Susosu’s trajectory is a concrete example of what’s possible with a validated product and a strategic path to scale.
