E3 Energy Cubes makes refrigerated, high-fiber protein bars built around egg white protein and grass-fed hydrolyzed collagen peptides — five flavors (Almond Cherry, Peanut Butter and Chocolate, Lemon Blueberry, Orange Cranberry, and Peanut Butter and Jam Strawberry) plus bundle packs. Each bar delivers 14–16g protein and nearly half your daily fiber from organic cassava root syrup, with no dairy, no soy, no sugar alcohols, and no artificial preservatives.

The brand's "3-cube" format is its standout feature — each bar breaks into three connected portions for flexible snacking. Made in Bluffdale, Utah. All ingredients are non-GMO. E3 is a WBENC Certified Women-Owned Business; Norris Cole, two-time NBA champion with the Miami Heat, is an investor.
