oHy

oHy is a hydrogen sparkling water brand out of Grand Rapids, Michigan, founded in 2024 by Trent Hartwig and John Green. The pitch is simple: ditch the harsh, over-carbonated seltzer format and replace it with something smoother, built around magnesium-generated hydrogen instead of straight CO2 injection.

The category oHy is chasing is crowded with zero-sugar sparkling water, but it's carving out a specific lane. Instead of leaning on stevia blends or aggressive fizz, oHy uses a magnesium dosing system that reacts with ultra-purified water to generate molecular hydrogen gas. That reaction produces smaller bubbles than typical carbonation, which the brand says gives the water a softer mouthfeel rather than the sharp bite you get from a traditional sparkling water can. Every flavor is zero sugar, zero calories, and zero sweeteners, and the flavoring itself is USDA Organic certified across the current six-flavor lineup.

That positions oHy less as a straight energy or nootropic play and more as a wellness-adjacent hydration upgrade. It's for the sparkling water drinker who's already cycling through La Croix and Spindrift but wants a functional hook without jumping into the stimulant category entirely. Founders and functional-water shoppers curious about hydrogen water as a category will find oHy an accessible, better-for-you entry point rather than a supplement-store curiosity.

There's also a regional identity baked into the brand. oHy backs conservation and restoration work tied to the Great Lakes watershed, tying its Michigan roots directly into its sustainability story rather than treating it as an afterthought.

oHy is built for the consumer who wants their sparkling water to do a little more without turning hydration into a science project: clean label, zero sugar, and a smoother sip than the category's usual suspects.
