Congratulations, you've found the ONE®.

At ONE™ we believe that great taste and good health are not mutually exclusive. Because let’s be real – life’s too short for anything boring, tasteless, or worse, chalky.

Since our founding as Oh Yeah!, we’ve taken our passion for flavour and shaped the perfect snack.

One with up to 20 grams of protein. One with up to 1 gram of sugar. One with totally indulgent flavours like Birthday Cake and Maple Glazed Doughnut.

So stop searching, and make it official – with our anytime dessert-level protein bars.

    So tasty and filling! It's a good option for when you're on the go.

    Horrible taste
  • CRYSTAL L (WINDSOR, ON) says:
    The size is great ad protein to calorie ratio is on point.

    Was really tasty and the texture wasn't chalky like other protein bars.

    It tastes great and not grainy and weird like other protein bars.
