What is sugar free soda?

Sugar-free soda is exactly what it sounds like — a soda with zero grams of sugar, made with alternative sweeteners instead of high-fructose corn syrup or cane sugar. But not all sugar-free sodas taste the same. Some rely on artificial sweeteners with a chemical aftertaste, or stevia blends with that telltale bitter, licorice-like finish. Others actually taste like soda.


On The Brightside™ is the only sugar-free soda built around a functional ingredient with real science behind it — Zembrin®, a science-backed extract of kanna used for centuries for calm, clarity, and social ease. Zero sugar, zero calories, and something worth reaching for.

Why do people look for sugar free soda?

Most people aren't looking to give up soda — they're looking to give up the crash, the calories, and the aftertaste that comes with it. Whether they're watching their blood sugar, cutting sugar without cutting flavor, or just done with the bitter compromise of most diet sodas, they want something that actually tastes like a treat.

How it works — the sweetener science

On The Brightside™ is sweetened with OnoSweet®, a patented, natural sweetener made through fermentation of rice — not stevia, not sugar alcohols, not artificial sweeteners. That fermentation process is what gives it a clean, sugar-like sweetness without the bitter or lingering aftertaste common in stevia-based sodas.


OnoSweet® also has zero glycemic impact, meaning it won't spike blood sugar — on top of zero sugar and zero calories across both flavors.

The result: a soda that's sweetened the way sugar tastes, without the sugar.
