Q: Which protein bar wins between Built, Barebells, and David Protein? David Protein leads on raw macros (28 g protein, 0–2 g sugar, 150 kcal). Built wins on texture and heat-stability. Barebells wins on flavour breadth and chocolate-coating quality. Pick based on your priority.
The 3 brands shaping the high-protein bar market in 2026
Three brands dominate the protein-to-calorie ratio race at Top Nutrition & Fitness right now: Built Bar (the marshmallow-pillow disruptor from Utah), Barebells (the Swedish chocolate-coated favourite), and David Protein (the 2024 newcomer that pushed protein density past every competitor). Each has a clear best-use case. This comparison is from inventory in stock at TNF in Montreal as of this writing.

Built Bar: the original marshmallow-soft disruptor
Built launched the "protein marshmallow" category. The defining feature is the airy whip texture (the inside is genuinely marshmallow-light), wrapped in real dark chocolate. Calories are the lowest of the three, but protein is also the lowest.
Built strengths
- 130 kcal per bar — the easiest fit in a cutting macro plan
- Unique marshmallow-soft texture (no comparable competitor)
- Wide flavour catalog including seasonal LE releases
- Heat-stable up to ~30 °C (better than most chocolate-coated bars)
Built trade-offs
- 17 g protein is below the 20 g threshold many lifters aim for per snack
- Contains some sugar (5 g) — not a true zero-sugar option
- Maltitol sweetener can cause GI issues for sensitive users at > 1 bar/day

Barebells: the chocolate-coated Swedish standard
Barebells popularized the "no chalky aftertaste" protein bar in Europe and arrived in Canada in 2018. The recipe is a candy-bar layered build: caramel or filling in the middle, protein nougat, chocolate coating.
Barebells strengths
- 20 g protein — a solid snack-size dose
- Excellent chocolate-coating quality (Belgian-style)
- Wide flavour catalog with high-quality candy analogues (caramel-cashew, hazelnut, salty peanut)
- Sucralose-only sweetener (no maltitol GI issues)
Barebells trade-offs
- 200 kcal is the highest of the three — less cutting-friendly
- 9 g fat reflects the chocolate coating
- Chocolate softens above 25 °C — keep cool in summer
- Slightly lower protein-per-calorie ratio than the other two

David Protein: the macro density king
David launched in 2024 with a clear pitch: highest protein, lowest sugar, lowest fat per calorie of any major bar. The Gold (28 g protein) and the new Bronze (20 g protein) lines split the catalog into two use cases. The Bronze format is closer to a traditional crispy bar, the Gold is a denser fudgy bar engineered for cutters and stage-prep lifters.
David strengths
- 28 g protein per Gold bar — highest in this comparison
- 0 g sugar in Gold, 1 g in Bronze
- Only 2.5 g fat (Gold) — best protein-per-calorie ratio in the protein bar category in 2026
- Allulose sweetener has minimal blood sugar impact and no maltitol issues
- Gluten-free certified
David trade-offs
- Bronze line is brand-new (early 2026) — flavour catalog still smaller than competitors
- Dense fudgy Gold texture is polarizing — some users love it, some prefer Built's airy texture
- Chocolate-coated — same summer storage rule as Barebells
