Chaga is a naturally occurring fungus traditionally harvested from birch trees and steeped into a dark, earthy infusion.

Ours is sourced from Northern Ontario and thoughtfully paired with organic cacao, Ceylon cinnamon and crisp carbonation—creating a clean, unsweetened and caffeine-free refreshment that feels both grounded and modern.

Clean and earthy, with subtle cacao depth, gentle cinnamon warmth and a refreshingly crisp finish. It is unsweetened, caffeine-free and intentionally crafted without an overly sweet or heavy flavour.

Founded in Northern Ontario, Fung-Ctional was created to bring a more thoughtful, modern approach to functional beverages. Through our partnership with TELUS, every item sold helps plant a seed—and every 100th supports the planting of a tree.
