Grindstone Blends is a Canadian performance-food company from London, Ontario, producing hot rice cereals and baking blends in a dedicated gluten-free facility. Its signature Hot Rice Cereal combines ground white and black rice — the black rice adding anthocyanin antioxidants and a lower glycemic profile than conventional cream of rice — for a clean, easy-to-digest carbohydrate source athletes use to fuel training and recovery. Bulldog Nutrition is an authorized Canadian and US retailer of Grindstone Blends, backed by 10+ years in the supplement industry.
Every Grindstone product is certified gluten-free, vegan, and free of wheat, dairy, soy, and nuts — sweetened with real ingredients like cane sugar, cocoa, dried blueberries, and stevia leaf extract rather than artificial sweeteners. With dessert-inspired flavours like Maple Butter Tart, Chocolate Fudge Brownie, Blueberry Cobbler, and Apple Pie, it's a made-in-Canada answer to the cream-of-rice carb staple.
