Best Protein Bars 2023 - As Chosen By You

If you're serious about fitness, health, and all things protein – then protein bars are most likely already on your radar. A good protein bar can fuel your body, enhance your performance, and promote muscle recovery to name a few! It's the perfect blend of convenience and nutrition, made for people on-the-go, weight-lifters, office workers, adventurers and anyone else in between.

However, the real challenge isn't deciding to incorporate a protein bar into your diet; it's finding one that tastes good and aligns with your personal preferences, health goals, and dietary needs.

So, what better way to put together the Best Grenade Protein Bars of 2023, chosen by our customers…

10. Caramel Chaos Protein Bar

It’s Chaos but for all the right reasons, with a whirlwind of gooey caramel goodness that satisfies your sweet tooth while delivering the protein firepower you need. Caramel Chaos may be last in this list, but don’t underestimate the OG Grenade Bar that put Grenade Protein Bars on the map!

9. Lemon Cheesecake Protein Bar

One of your 5 a day? Not quite, but the tantalizing tang of lemon cheesecake in this Protein Bar means business and shouldn’t be missed. Launched in the Summer 2022 in true bursting-citrusy style, we’re proud the Lemon Cheesecake has paved its way into the catalogue of Grenade’s best protein bars. It’s so good, that this was only meant to be limited edition until you lemon suckers forced us to make it permanent!

There’s no fudging about with this incredible bar, and clearly our customers agree as this lucky bar locks in as our 7th best seller for 2023. Stacked with only 1.7g Sugar and a mix of the three most important things in life… chocolate, fudge and lots of protein, it should be illegal for a Protein Bar to be this good.
