A Word from our Founder

“I wanted a better bar. No, more than that. I wanted a bar with good nutrition and great taste. As a certified personal trainer and fitness nutrition coach, I have watched my clients and their families struggle to find ways to eat right while-on-the-go. I looked at the protein and energy bars on the market and was disappointed with their nutrition. I knew I could do better, and I did.”

Catalyst Chocolate Protein Bar
The Catalyst bars are now a standard part of my morning routine. It is very tasty, and it has a dense texture which helps me slow down my eating. The chocolate flavor is nicely balanced. I especially like the absence of any artificial sweeteners, as I am unable to digest them. For this reason alone, I cannot eat most other bars. It is also cost-competitive with similar protein bars. For me, the Catalyst bar is a great choice.

The new Catalyst bar has a great taste and mouth feel. It gets me through a 4-hour round of golf even in Florida’s 90+ degree heat. And the added bonus is that it’s healthy!

Frequently Asked Questions

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

For a food to be “high” in protein, it must contain 20% or more of the recommended daily value (DV) per serving size. The DV for protein is 50 grams, so each serving size must contain more than 10 grams of protein to have the “High in Protein” nutrient content claim. Catalyst Bars have 20 grams of protein per bar which is twice the requirement. And, we use high-quality whey protein isolate, unlike many other bars on the market.

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 Recommended Daily Allowance (RDA) for dietary fiber is 25 grams per day for a 2,000 calorie diet and 30 grams per day for a 2500 calorie diet. According to the Academy of Nutrition and Dietetics, this translates to women taking in at least 25 grams a day, and men 38 grams a day. Catalyst Bars have 12 grams each, nearly half of the RDA.

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.

Do you ship internationally?
