Pure Protein is one of the most recommended budget protein bars online. The pitch is simple: 20 g protein, gluten-free, around $1.50 or $2.00 a bar. But nobody mentions which flavor to grab, as if they're all the same.
They're not. We ranked all 13 flavors against over 400 protein bars in our catalogue. Protein per 100 kcal ranges from 11.67 g (Chocolate Deluxe) down to 9.5 g (Chocolate Salted Caramel). Fat swings from 9 g to 14 g per 100 g. Carbs range from 32 g to 40 g per 100 g. Those differences are enough to shift a flavor's ranking by 40 places — from #20 to #60 out of 414 bars.

The full ranking
We score every product using our XRay Score — a composite 0–100 rating that weighs protein efficiency, value for money, leanness, low carbs, and fiber. Here are all 13 flavors ranked by it. Every one lands in the top 15% of all 414 bars in our database — Pure Protein as a brand is genuinely strong. But within that top tier, the spread is real.

The first thing that jumps out: all 13 flavors use the same protein source — a milk protein blend — and come in the same 50 g bar format. Unlike Quest's powder line (where the protein source changes by flavor), the differences here come entirely from the other ingredients: the coatings, fillings, and flavor systems that shift fat, carbs, and calories from one bar to the next.
Why Cookies & Cream wins
Cookies & Cream takes the top spot because it's the only flavor that doesn't have a glaring weakness. Most Pure Protein bars trade one macro for another — low fat but high carbs, or decent protein but zero fiber. Cookies & Cream is the one that holds up across the board: 40 g protein per 100 g, 12 g fat, 36 g carbs, and — critically — 8 g fiber per 100 g (4 g per bar). That last number is what separates it from the pack. It's the only flavor with meaningful fiber, which pushes its composite XRay Score to 82.4 and earns it rank #20 out of 414 bars.
It's not the leanest (that's Chocolate Deluxe at 9 g fat) and it's not the cheapest ($1.42/bar vs $1.24 for Chocolate Deluxe). But it's the most balanced, and the fiber advantage is enough to pull it ahead in the overall score.
The top-ranked Pure Protein flavor — the only one with meaningful fiber.
The protein and calorie leaders
If you're optimizing for protein per calorie rather than low carbs, the leaderboard shifts:

Chocolate Deluxe delivers the most protein in the lineup — 42 g per 100 g (that's 21 g per bar) — while tying for the fewest calories at 360 per 100 g with Chocolate Mint Cookie, Galactic Brownie, and Brookie. It also has the least fat at just 9 g per 100 g. If your only goal is "most protein, fewest calories," Chocolate Deluxe is the answer.
The leanness tier
Fat content varies more than you'd expect across the range. The leanest flavors carry 9–10 g of fat per 100 g, while the fattiest hit 14 g — a 55% difference.
The three leanest — Chocolate Deluxe, Chocolate Mint Cookie, and Galactic Brownie — all sit at 9 g fat per 100 g (4.5 g per bar), ranking in the 95th+ percentile for leanness among all 414 bars. At the other end, Chocolate Peanut Butter, Lemon Cake, and Sundae Cone carry 14 g fat per 100 g (7 g per bar). Peanut-based flavors naturally carry more fat.
The carb spread
Carbs across the range run from 32 g to 40 g per 100 g (16–20 g per bar). That's a narrower window than fat, but it still matters — especially if you're tracking net carbs on a cut or a low-carb diet.

Lemon Cake and Chocolate Peanut Caramel tie for the fewest carbs at 32 g per 100 g (16 g per bar). At the other end, Chocolate Salted Caramel and Chocolate Mint Cookie carry 40 g per 100 g (20 g per bar) — a 25% gap from lowest to highest.
For sugar specifically, Galactic Brownie stands out at just 2 g sugar per 100 g (1 g per bar) — the lowest in the entire lineup. Most flavors sit between 4–8 g sugar per 100 g.
Value: the price spread
Prices vary by retailer, region, and pack size — these are based on the best per-bar prices we found at the time of writing and may have changed since. That said, the relative spread between flavors is worth noting.
Per serving, prices range from $1.24 (Chocolate Deluxe, Chocolate Peanut Butter) to $1.79 (Chocolate Mint Cookie, Caramel Churro, Brookie). That's a 44% price gap within the same brand.
Chocolate Deluxe is the standout: highest protein per calorie, tied for leanest, and the cheapest per bar. Chocolate Peanut Butter matches the price but carries the most fat — value depends on your priorities.

What about fiber?
Fiber is the weakest dimension across the entire Pure Protein range. Most flavors report 0–2 g fiber per 100 g, and several don't have fiber data at all. The exception is Cookies and Cream at 8 g per 100 g (4 g per bar) — the only flavor that registers meaningfully on fiber. If fiber matters to you, it's the clear pick, and it also happens to rank #1 overall in the lineup.
Pure Protein isn't engineered for fiber — it's built for protein density and value. If fiber is a priority alongside protein, check our piece on why fiber matters on a high-protein diet.
The bottom line
Every Pure Protein bar in our database ranks in the top 15% of all 414 bars — the brand's reputation as a reliable, affordable protein bar is well earned. But within that strong lineup, your flavor choice matters more than you'd think.
