New recipe - I'm a fan!

I was a bit worried that the recipe change meant this was morphing into a mainstream "candy bar with protein sprinkled on top"... nope... this is the bar I always loved, but a bit chewier :) well done!

Very dense bar is quite difficult to chew. Basically just like an RX bar. I’d hoped for something so much more satisfying!

Too hard

The flavor of these bars is good, kind of like a tootsie roll, but they are too hard to bite. I ended up cutting them into bite sized pieces; about 12 per bar.

Chocolate fuel bar

Very filling. Accidentally left out on hot car. When I had the bar it had an "eggy" flavor. It was not at all sweet, which I wish it was a bit, but no "eggy" flavor at room temperature.

Frequently Asked Questions

What are net carbs?

You determine the net carb impact of a food by subtracting the grams of fiber from the total grams of carbohydrates. Fiber slows the digestion of carbohydrates and reduces the glycemic burden on the body.

What is monk fruit?

Also called Luo Han Guo, monk fruit comes from a Chinese plant cultivated for centuries by Buddhist monks. Much like stevia, it’s a delicious and natural way to sweeten without all the calories or sugar.

What is collagen?

Collagen is one of the most abundant proteins your body, accounting for about a third of its protein composition. Collagen production naturally declines with age. Collagen may be sourced from animals and fish and made into edible powders.

Where does your collagen come from?

Our collagen comes from cattle ranches in South America. While the cows are grass fed for most of their lives and traditionally raised on pasture, we chose to remove the grass-fed claim from our labels in 2018 due to some retailers requiring documentation showing 100% grass-fed, which is not attainable in the collagen supply chain at this time. Be assured that we strive to source high quality collagen peptides from well-established manufacturers with high-quality standards. This includes consistent testing of heavy metals and product purity in order to comply with stringent regulatory guidelines. In addition, we have worked hard to source collagen with the best flavor profile and ability to dissolve in liquids.

Do you have a money back guarantee?

Yes! We offer a 30-day money back guarantee. If you aren’t completely satisfied with the product, simply return it and we’ll refund you.

What are Isomalto-Oligosaccharides?

They are simply Prebiotic Tapioca fiber!
