Most protein bars pack in protein—but also artificial sweeteners and fillers that spike your energy, upset your gut, and leave you crashing soon after.

Designed in collaboration with a Naval Special Warfare nutritionist after C1 founder—Matt Demaio—struggled to find proper nutrition while deployed, Condition One takes a different approach. Built with whole foods and balanced macros, C1 bars are designed for steady, reliable fuel without compromising on protein quality.

Here’s what happens in your body after eating a C1 bar

30 SECONDS

Whey Protein and Egg: These clean protein sources take longer to break down than carbs, making you feel fuller for longer periods—essential for prolonged adventures.

25 - 40 Minutes

Oats: Oats break down slowly ensuring glucose releases into the blood providing a steady energy supply. This helps prevent a spike and crash.

Almonds: This superfood enhances carbohydrate utilization, transporting glucose to muscles during exercise for prolonged endurance before fatigue sets in.

Brown Rice: Helps manage lactic acid levels, reducing fatigue and muscle soreness, thus increasing endurance.

Brain Energy: The carbohydrates provide a continuous glucose supply to the brain, enhancing quick decision-making, better concentration, and improved focus.

Eggs (Leucine): Further breakdown releases leucine, vital for muscle energy and rebuilding, reducing soreness and recovery time.

High Protein Content: With 25 grams of protein, absorbed over 2 hours, our bars provide sustained muscle endurance and recovery. Compared to other bars with only 10 grams, our bars ensure continuous muscle protein supply.

MCTs from Coconut Oil: Provide immediate, non-crash energy, beneficial for quick, reliable energy during operations.

Almonds: Reduce inflammation from physical exertion, extending workout duration and promoting faster recovery.

Stable Blood Glucose: Prevents energy spikes and crashes.

Poly-unsaturated and Mono-unsaturated Fatty Acids (Avocado Oil & Coconut Oil): These acids reduce soreness, regulate blood glucose, and enhance lipid oxidation for sustained energy, reducing fatigue.

Fiber Breakdown: Forms short-chain fatty acids, stabilizing insulin and blood glucose responses, ensuring stable energy levels, and reducing hunger during extended activity.

Conclusion: Fuel That Works

What you eat matters—and how your body uses it matters even more. Clean, effective fuel isn’t about flashy numbers or artificial boosts. It’s about steady energy, clear focus, and real recovery.

C1 bars are built with that in mind: whole foods, balanced macros, and nothing that sets you up to crash later. Because when the mission demands more from you, your fuel shouldn't fall short.

My husband and I do a lot of hiking and mountaineering and these bars are a staple in our food kit. Durable, sustainable, and delicious. We’ve been asked about them many times on our adventures. Thanks for making such a nutritious choice for on the go.

Great post-workout or mid afternoon healthy protein snack. Tastes great, not too sweet, good consistency, feels home baked.

I really enjoy all the flavors I have tried. They are substantial bars with a really good amount of whey protein. Have bought them several times and will continue to do so.
