  • Do they taste like coffee?

    Each bar has organic green coffee, but only the Cafe Mocha flavor actually tastes like coffee.

    It’s no secret that most energy bars on the market put “taste” on the back burner, but we front-burnered taste by hiring a pastry chef! We may be the first sports nutrition bar company that hired a pastry chef (in addition to a sports dietician and a food scientist).

    And that was just the start: after over 200 recipes and iterations — tested in focus groups, events, and anywhere there were active consumers with appetites — we landed on a selection of all-natural, award-winning flavors that will satisfy even the pickiest palates. There’s no reason real energy can’t taste real good.

  • When do I eat these bars?

    The right time for QUANTUM is...Before a workout, a jog, a bike ride or while hiking with friends. First thing in the morning, to get a jumpstart on your busy workday. Before or during an Ironman triathlon, a tennis match, or your local 5k fundraiser walk. As a midday pick-me-up snack (when you might have once reached for a sugary energy drink or a cup of coffee). Basically anytime you need a boost of long-lasting energy!

    Quantum Energy Squares are designed to deliver steady, long-lasting energy and support overall wellness. As part of your fitness plan, consumed ~20 minutes before a workout, or during or right after, they give you the energy to push your performance, reach new highs, and recover faster. As part of your diet, they satisfy cravings with a nutritionally balanced snack, one that can help increase focus, productivity and clarity. Perhaps the only time you might not eat one is before bedtime (because of the organic caffeine).

  • Can these bars replace coffee?

    Yes. We get you going with about a cup of coffee’s worth of caffeine (100mg). While a cup of coffee doesn’t provide essential nutrients and coffee alone can cause jitters, stomach upset or a “coffee crash”, our bar bars feature a unique blend of organic green caffeine and a curated balance of macronutrients, developed by a sports dietitian and a food scientist, so active customers can benefit from the energy organic caffeine provides, while avoiding the jitters some experience drinking coffee by itself without essential nutrients.

    Our balanced macros (a nourishing energy mix of complex carbs, healthy fats and plant-based proteins), combined with organic caffeine, is specially formulated to be easy on the stomach—taking the edge off caffeine. Premium pumpkin seed protein combined with MCT oil (from coconut) helps slow caffeine absorption to give you the energy boost you need for long workouts or workdays. Steady, long-lasting energy. No jitters, no crash.

    And, we only use the healthiest form of natural caffeine, from raw organic green coffee. Coffee is a plant, and as we all know, eating uncooked plant-based foods is beneficial for retaining nutritive value. The organic green caffeine in Quantum Energy Squares brings antioxidant, anti-inflammatory and additional benefits which may be adversely affected by roasting.

  • Are all Quantum Energy Squares gluten free?

    Yes, all Quantum Energy Squares are Certified Gluten Free and they’re also:

    √ 100% Plant-based Certified
    √ NON-GMO Project Verified
    √ Kosher DE (Dairy Free) Certified
    √ Vegan
    √ Soy Free

    BTW, each bar also has 10g of premium Plant Protein from peas and pumpkin seeds (no whey or soy).

  • What's in these bars?

    While many popular energy bars contain over 20g of sugar and more than 40g of carbs, we’re setting our own standards for energy and wellness; QUANTUM is designed to deliver long-lasting energy with more protein, fewer calories, carbs and sugar as well as clean, nutrient-dense ingredients.

    Our bars contain just 11g of natural sugar from fruits such as dates, organic agave and monk fruit (and a touch of organic dark chocolate), and just 21g of carbohydrates from fruits and seeds such as chia seeds. Learn More

  • How much caffeine can I consume each day?

    Caffeine's effect varies from person to person. Each Quantum Square contains 100mg of natural caffeine from organic green coffee. The FDA suggests that it is safe to consume 400mg of caffeine a day for a healthy adult. If in doubt, we recommend checking with your doctor.

    We do not recommend our bars if you are intolerant to caffeine, pregnant, lactating or to children under 13 years of age.

  • What makes QUANTUM better?

    Quantum isn’t just energy, it’s Better Energy.

    Here’s why...

    Quantum Energy Squares are designed to provide steady, long-lasting energy without jitters. While many of the energy bars and caffeinated energy products on the market will give you a blast of caffeine energy, or a “sugar high,” it’s invariably followed by a crash, which always hurts energy levels and performance.

    Our Energy Squares are made of real food and wholesome ingredients. And while they have about the same amount of natural caffeine as a cup o’ jo (100mg), it’s from raw organic green coffee. The blend of organic caffeine with balanced macros from seeds, fruits and nuts, and MCT oil (from coconut) delivers better energy — without the crash.

  • Why is raw organic caffeine better & healthier?

    Quantum’s organic green caffeine is better caffeine. While both raw, green coffee beans and roasted, brown coffee beans have naturally occuring caffeine, that’s about where the similarities end. Roasting coffee beans changes their composition, their taste, and — while it does ramp up the amount of caffeine in a serving — it can also roast away beneficial nutrients, such as chlorogenic acid (found in raw, green coffee beans), which can help the body burn glucose and stored body fat.

    And studies have shown that natural caffeine is rich in antioxidants, anti-inflammatories, polyphenols, and it can even help speed recovery when consumed post-exercise.

    Some energy products contain synthetic caffeine, which is not only missing essential nutrients and health benefits, it can also cause stomach upset.

  • How do these bars provide long-lasting, jitter-free energy?

    Caffeine alone, sugary drinks or gels, consumed without essential nutrients from food, can lead to an energy spike, followed by a crash.

    QUANTUM provides a nutritious blend of clean macros from seeds, fruits and nuts, infused with natural caffeine (from organic green coffee). Our unique premium blend of organic caffeine combined with premium plant protein and MCT oil (from coconut) is designed to deliver even, jitter-free energy — with no spike or crash. Our bars are formulated to deliver the steady, long-lasting fuel reserves you need to elevate performance, whether it’s kick-starting your busy workday or your daily workout.

  • Are these bars good as pre-workout fuel?

    Yes! Eat Quantum Energy Squares about 20 minutes before any exercise activity and experience the results from our unique blend of organic caffeine and balanced macros.*

    They’re also great for a jumpstart to your busy morning, keeping up with energetic kids, recharging when the “3pm slump” hits, road trips, and more...

    *Note that this is not merely our opinion: there’s hard science behind this.

    According to analysis done by Dr. Bob Murray, founder and principal of Sports Science Insights, and former director of the Gatorade Sports Science Institute, in “The Scientific Rationale Behind Combining Caffeine + Macronutrients for Sustained Energy Delivery Required in Endurance Sports”:
    “Scientific literature confirms that consuming caffeine in amounts similar to that found in Quantum Energy Squares (100 mg) is associated with improved mental and physical function when ingested before and/or during demanding exercise.”

Hey there,

I’m Dan! I’m a coffee guy and tennis player. I love the mental energy I get from caffeine, but coffee before tennis gave me jitters and occasionally upset my stomach. So I turned to bars.

Bars promising energy were packed with simple carbs led to a sugar crash and couldn’t replace the mental energy I loved from coffee. Unwilling to compromise and unable to find the right source of energy to play at my best, my partner Leah and I had an idea⚡

After countless hours in the lab with a food scientist and sports dietitian, and over 150 recipes with a pastry chef, QUANTUM was born.

QUANTUM’s unique energy blend delivers complete mental and physical energy, combining the benefits of balanced plant-based macronutrients and clean caffeine in one bar, providing long-lasting energy with no jitters or crash.

Energetically yours,
Dan, Leah (& Joe!)
