Sugar alcohols wreck most protein bars. We left them out.
Maltitol and erythritol cause the bloat. Peak is sweetened with monk fruit, that's it.
Every Peak bar is built on real peanut butter, milk chocolate, and grass-fed whey — sweetened only with monk fruit. You get the dessert hit you want, with none of the aftermath you don't.
“I've tried every 'clean' protein bar on the market and most of them still wrecked me. Peak is the only one I can eat daily without my stomach hating me.”

Frequently Asked Questions
Peak is built as a real-food bar, not a diet bar. The 290 calories come from real peanut butter, milk chocolate, and grass-fed whey, not from filler ingredients engineered to hit a low number. With 20g protein and 7g fiber, it's filling enough to be a snack or a small meal, not just a treat.
Protein quality matters as much as quantity. Peak uses grass-fed whey isolate + hydrolyzed whey concentrate, a complete protein that supports muscle the way protein is supposed to. We'd rather give you 20g of protein you actually want to eat than 28g you can barely choke down.
Yes. Every Peak bar is sweetened with monk fruit. No maltitol, no erythritol, no xylitol. This is the single most important thing on the label for most of our customers, and the reason most of them stay.
Peak uses real milk chocolate, which means it behaves like real chocolate. In warm cars or hot weather, store cool. We'd rather use real chocolate that occasionally needs care than fake chocolate that doesn't.
