Plenny Bar v3.0 vs v4.0! What changed?

Same mission, smarter formula. Plenny Bar v4.0 is the next step up from v3.0: more protein, a tweaked macro balance, a boosted omega-3 content, and a refreshed ingredient lineup, all while keeping the satisfying, nutritionally complete Jimmy Joy bar experience you know and love.

Below is a clear breakdown of what changed and why it matters, based directly on the official product specifications for v3.0 and v4.0.

The big picture (TL;DR)

More protein, same calories → v4.0 delivers 25g protein instead of 20g, without adding a single calorie.

Lower carbs, higher satiety → Carbs drop from 38 g to 33 g, while protein goes up.

More Omega-3 → Omega-3 content jumps from 1,480 mg to 2,100 mg (+42%).

New protein source → Pea protein is added to complement the existing soy protein.

Same complete nutrition promise → 20% RI of energy, macros, vitamins, and minerals per bar

Available in 6 flavours: Vanilla, Chocolate, Caramel Sea Salt, Lemon Pie, Choco & Coco, and Cherry.

New macronutrient balance

More protein, fewer carbs. That's the deal! Check out the comparison between the Plenny Bar v3.0 and v4.0, so you're totally in the loop!

The comparison is between both vanilla flavoured bars.

 

In short, Plenny Bar v4.0 delivers significantly more protein and lower carbohydrate count compared to its predecessor, all at the exact same caloric value.

Protein source and function

Both bars share a core soy-based protein foundation — soy protein isolate and soy protein crisp — but v4.0 adds a new player to the mix:

Hydrolyzed pea protein is a brand-new ingredient in v4.0, introduced specifically to boost total protein content. Pea protein is a high-quality plant-based source with a favourable amino acid profile that pairs well with soy.

Omega-3 upgrade

One of the quieter but meaningful upgrades in v4.0 is the significant jump in omega-3 content — from 1,480 mg to 2,100 mg per serving (+42%). This improvement comes from the same source as always, rapeseed oil and milled brown flaxseed, just at an optimised proportion. Omega-3 fatty acids support brain function, heart health, and inflammation response, making this a worthwhile upgrade.

Note on the probiotic:

The name change from Bacillus coagulans to Heyndrickxia coagulans reflects an updated scientific reclassification. Same probiotic strain (MTCC 5856) you've always been getting, just with its proper new taxonomy.

Wrapping it up

Plenny Bar v4.0 takes everything you liked about v3.0 and dials it in. You still get a 400 kcal nutritionally complete meal, low in sugar, fully plant-based, and packed with all 26 essential vitamins and minerals — but now with 25 g of protein, fewer carbs, a bigger omega-3 punch, and an upgraded ingredient blend including hydrolysed pea protein.

V4.0 is designed to keep you full, fuelled, and feeling good for longer.
