From the brand
What is smooth energy?
Our combination of natural caffeine and real whole foods create a steady rise in energy levels that comes down gradually, so that you can feel energized longer.
What makes Quantum different from other energy bars?
Most bars rely on sugar for “energy” with little nutrition. Quantum delivers whole food nutrition plus the right amount of natural caffeine.
Why not just have an energy drink?
Energy drinks cause spikes and crashes from synthetic caffeine and sweeteners. Quantum blends natural caffeine into a protein bar for steady energy.

CAFFEINE x PROTEIN: Quantum delivers the lift of an energy drink plus the clean nutrition of a healthy snack in one tasty square.
MORE ENERGY THAN OTHER BARS: Get the lift you need with 100mg of natural caffeine, equal to an 8oz coffee (instead of “energy” from sugar and simple carbs).
BETTER NUTRITION THAN ENERGY DRINKS: Power through your day with natural caffeine & premium protein (avoid the synthetic caffeine and chemicals).
CLEAN NUTRITION: Whole Food Ingredients, Nothing Artificial. Certified Plant-Based, Gluten Free, Non-GMO Project Verified, Kosher, Vegan. No Dairy, Soy, or Sugar Alcohols.
MID-DAY ENERGY: Easy to take with you anywhere, perfect for exercising, mid-day snacking, work, school, and travel. Swap your energy drink, second (or third) coffee, or pre-workout snack.
CHEF-CRAFTED FLAVORS: Naturally delicious with fruits, nuts and seeds, each flavor offers a unique crave-worthy taste. Whether it’s rich organic chocolate chips, creamy nut butter, or a satisfying quinoa crunch.
Customers say
Customers enjoy these energy bars for their great taste, variety of flavors, and ability to provide steady energy without a crash. The bars contain the right amount of caffeine and are made with clean, plant-based ingredients, making them convenient to carry on the go. They are particularly effective as a pre-workout snack, and one customer notes that 10g of protein keeps them full. The texture receives mixed reviews, with some finding it nice and dense while others describe it as hard.
