You’re only as old as you feel. Which is great, because ONE Birthday Cake is filled with 20 grams of protein, giving you the energy you need to perform at your peak. And with just 1 gram of sugar, you can celebrate morning, noon or night, any day you want. Let’s light this candle and get this party started.


When it comes to snacking, every single one of us is entitled to the perfect match. And at ONE we believe that great taste and good health are not mutually exclusive. But those other chalky protein bars? A definite swipe left (and let’s be real – life’s too short for boring anything.) So we’ve taken our passion for flavor and shaped the perfect snack. One that’s loaded with protein. One that’s low in sugar. One with totally indulgent flavors that seem too good to be true. So stop playing the field, and make it official – with our anytime Guilt Free Indulgence.

Congratulations, You’ve Found the ONE.

    These bars are now a staple in my pantry. I eat one pretty much every day for breakfast. I’m in the maintenance phase of the Medifast plan and one bar is exactly 2 options. Wish I could buy in a larger bulk package!

    I love these. They’re filling and great for an on the go meal. Breakfast for me daily ! These are expensive. Supps Direct has a great price on them. I will only buy them here.

    I got super hooked on these bars a few months ago and am totally in love with this flavor. I’ve tried lots of different flavors from this brand but this one hits a home run for me. I love how it doesn’t taste like gross protein. I sometimes put these in the fridge and eat half of one as a dessert since I have a killer sweet tooth.

    Lets face it, finding the perfect protein bar is a challenge. It may not exist, but this is pretty close. I love the donut flavor. Another added bonus of these is that it does not upset my stomach or give me the “protein farts”. Highly recommend.
