Protein Bars Ranked

This bar has 20g protein but 18g polyols, mostly maltitol, which can cause laxative effects and IBS symptoms like bloating and flatulence.

GRENADE'S CARB KILLA (CHOCOLATE CHIP SALTED CARAMEL)

No need to eat them all at once, so they are great for portion control. They contain no polyols and are made with natural ingredients.

THE PROTEIN BALL CO

The protein bar is a nutrient-poor snack. While lower in calories, fat, and sugar than a regular Mars Bar, it is high in saturated fats.

MARS HI PROTEIN BAR

These mini-bars are perfect for when you're craving something sweet and are around 150 calories.

MAXIMUSCLE'S NEW YORK VANILLA CHEESECAKE BAR

Though not overly sweet and textured, this bar is not a Snickers competitor. High in saturated fats, it should be included in your daily saturated fat intake.

BAREBELLS PROTEIN BAR (SALTY PEANUT)

They are nut-free, vegan-friendly, and gluten-free. We ate every flavour we tried.

CREATIVE NATURE

A protein-inspired sweet treat with protein bar benefits, Bulk's Protein Millionaires Slice is a favourite of ours. It is a large protein bar serving size.

BULK'S PROTEIN MILLIONAIRES SLICE

With only 9g protein and a price tag of nearly £40 for a box of 15, this isn't cheap. Only 150kcal per bar, compared to other bars.

BEACHBAR CHOCOLATE ALMOND CRUNCH

While this bar didn't win our taste test, we appreciate Bodyhero's commitment to the environment with 100% recyclable packaging made of sustainable materials.

BODYHERO PLANT PROTEIN RICH CHOCOLATE

These are a more natural protein bar than some others on the market, but there are others. It's always worth comparing saturated fat content.

EAT NATURAL

However, they do not contain polyols, making them a better option for those with IBS. In the bars, soy protein replaces whey protein in terms of nutrients.
