A Word from our Founder

“I couldn’t find a better bar, so I made one. As a personal trainer and nutrition coach for more than 15 years, I watched my clients search for a protein bar that offered strong nutrition and actually tasted good. Too many bars melted in a gym bag, tasted chalky, or left an unpleasant aftertaste. So I created Catalyst. Each bar is high in protein and fiber, low in sugar, and contains zero sugar alcohols. It’s soft, shelf-stable, portable, and made to fit easily into busy days, workouts, travel, or anytime you need convenient nutrition.”

    Catalyst Protein Bars have clean, high-quality ingredients and a great taste. They don’t have the chalky texture or artificial sweetener aftertaste that many protein bars do. They’re delicious, satisfying, and feel more like a real snack than a typical protein bar.

    Packaging: 9/10 — it looks fantastic.
    Texture: 9/10 — I was worried it was going to stick in my teeth like an RX Bar, but it did not.
    Taste: 9/10 — the taste is great, I love it.

    Most protein bars are either a dessert or a disappointment.I like that Catalyst Bars are actually created by a trainer. They are meant for real life and not just to look good on the label. For me, that means grabbing one on the way to the gym, in between meetings, when I need something quick. They don’t melt in your bag which is huge. And the texture is not chalky at all. They are actually really good. Sometimes I like to warm them up for 15 seconds in the microwave and that makes them feel like a little treat. I think the biggest thing is just having something that keeps you full when your day gets busy. It’s simple. It fits into real life and that’s kind of the whole goal.

    Just trust me on this…air fry your chocolate Catalyst Protein Bar…you won’t regret it! With real ingredients like almond butter, oats, peanuts, and dark chocolate (not to mention 20g of clean whey protein), this air-fried protein bar comes out tasting EXACTLY like your favorite new dessert!

    Air Fry It. Thank Me Later.

    I found your new favorite protein bar and I’m blown away! I’m always on the hunt for a high-protein, good-tasting snack that is portable for long days or travel… It has 20 g of protein, is made with all natural ingredients, and TASTES LIKE A TREAT!! It’s created by a female fitness pro (she knows her stuff!).
    And, IT DOES NOT MELT!!! (Finally a bar I can leave in my car!)
    It even transforms into a new treat in the microwave or air fryer. YUM. I can’t get enough!!

    I’ve tried enough protein bars to know that most of them are glorified candy with a gym logo on the wrapper. Catalyst is different. The chocolate flavor is genuinely good: dense, satisfying, and not artificially sweet. But what kept my attention was the label. 20g whey isolate, 12g real dietary fiber, zero sugar alcohols, and every ingredient is something you’d actually find in a kitchen. That’s rare in this category. I cross-referenced it against Quest, David, and Built. The competitors either load up on sugar alcohols, strip out fiber entirely, or pad their formulas with fillers. Catalyst doesn’t play those games. Considering the price point and the nutritional value you receive, this is one of the most honest products I’ve come across. Solid bar – I’ll be ordering more.

Frequently Asked Questions

What does “High Protein” mean? How can you claim this to be true?

For a food to be labeled “high” in protein, it must provide at least 20% of the Daily Value for protein per serving. The Daily Value for protein is 50 grams, so a food must provide at least 10 grams of protein per serving to qualify. Each Catalyst Protein Bar provides 20 grams of whey protein isolate—40% of the Daily Value for protein.

Are Catalyst Bars really so low in sugar?

Yes! One of our priorities was to develop great-tasting bars with no more than 5 grams of sugar and 0 grams of sugar alcohol. Our team of chefs and nutrition scientists worked through many trials to develop this recipe. The end result is a bar with high protein and high fiber, low sugar, no sugar alcohols, and of course, a delicious taste!

What is “High Fiber”?

The Daily Value for dietary fiber is 28 grams per day. Each Catalyst Protein Bar provides 12 grams of fiber, which is more than 40% of the Daily Value in one bar.

How should I store my Catalyst Bars?

Catalyst bars are shelf-stable and do not need refrigeration. Keep them in your kitchen cabinets or pantry, and stow a few in your desk, work bag, purse, gym bag, and rucksack so you always have a delicious and nutritious option nearby.

I am allergic to nuts. Is it safe to enjoy Catalyst Bars?

No. If you have a peanut allergy or tree nut allergy, PLEASE DO NOT TRY CATALYST BARS. We do our best to make it clear on our website and packaging that these bars contain peanuts and/or tree nuts.
