Consider it. The budget pick — 21 g for ~$1.30 a bar, with a maltitol caveat that keeps it honest. 21 g of mostly-complete dairy protein (milk + whey isolate + whey concentrate) for about $1.30 a bar — the best price per gram here by a wide margin, and it clears the ~20 g MPS dose (Moore 2009).

Why It Scores 7.3 — And The Label Line Behind Each Number
Protein quality & amount
35% of score21 g of mostly-complete dairy protein — milk, whey isolate and whey concentrate — which clears the ~20 g MPS-maximizing dose (Moore 2009). The catch is a hydrolyzed gelatin binder (an incomplete protein), so a small share of the count is padding; the majority is real, usable dairy protein.
- Protein
- 21 g (milk + whey isolate + whey concentrate; gelatin/collagen used as binder)
Ingredient quality
30% of scoreThe weakest ingredient deck among the picks: it leans hard on maltitol and maltitol syrup — the sugar alcohol most associated with gas and GI distress — plus sucralose and a hydrolyzed gelatin binder. 3 g sugar reads fine, but the sweetener and binder choices are why this axis scores low.
Value per gram of protein
20% of score~$1.30/bar for 21 g is about $0.062 per gram — by far the best price per gram of protein in the lineup, roughly a third of David's per-gram cost. As SAC policy states plainly, powder and whole food still beat every bar, but among bars this is the value leader.
- Count / price
- 12-count box, ~$16

- ~$1.30 — the lowest in the lineup
- Cost per gram protein
- ~$0.06 — the best value here
Taste & texture
15% of scoreChewier and more processed than the bars above it — perfectly edible, but it tastes like the budget option it is. Fine for the price, and not a reason to buy or avoid it on its own.
Source-provenance & label honesty
0% of scoreNon-weighted SAC transparency gate. The maltitol load and hydrolyzed gelatin binder are disclosed on the panel, but the '21 g protein' includes the gelatin binder, so a slice of the count is incomplete protein — a modest honesty knock, in line with its bottom-of-lineup placement.

Marketing Claims Vs. Reality
21 g of protein.
The bulk is mostly-complete dairy protein — milk, whey isolate and whey concentrate — which is genuine and usable. But hydrolyzed gelatin, an incomplete protein, is used as a binder, so a small portion of the 21 g does less muscle work than the number implies. Mostly real, partly padded.
Cheapest / best-value protein bar.
At ~$1.30 a bar for 21 g — about $0.06 per gram — it is unambiguously the best price per gram in this lineup, a fraction of David or Legion. The value claim is fully accurate and the basis for the 'best budget' badge.
Low sugar (3 g).
The 3 g sugar figure is accurate, but the low number is held there with a heavy maltitol and maltitol-syrup load. Maltitol is the sugar alcohol most likely to cause gas and GI upset, so '3 g sugar' is true while understating the sugar-alcohol burden.
Good source of protein.
At 21 g of mostly-complete dairy protein it clears the ~20 g that maximally stimulates MPS (Moore 2009), so as a functional protein dose it delivers — the ingredient quality, not the protein amount, is what holds it back.
What Our Test Actually Found
Unbeatable on price per gram
At about $0.06 per gram of protein, Pure Protein is roughly a third the per-gram cost of the premium bars and cheaper than every other pick here. If budget is the binding constraint and you just need convenient protein, this is the honest answer.
The maltitol load is why it sits at the bottom
Pure Protein holds its 3 g sugar with maltitol and maltitol syrup — the sugar alcohol most associated with gas and GI distress. That's the single biggest reason it ranks last despite strong price and a solid protein count; sensitive stomachs should be cautious.
A gelatin binder means the 21 g is mostly, not fully, complete
Hydrolyzed gelatin — an incomplete protein — is used as a binder, so a slice of the headline count is padding. The majority is real dairy protein, so it's not the collagen-heavy story Barebells tells, but the number is slightly softer than it looks.
Quality-over-price still applies — this is the value tie-breaker, not the winner
Per SAC policy, price is a tie-breaker, not a trump card: Pure Protein wins on cost but its ingredient deck is the weakest here, which is exactly why it's ranked #8, not near the top. Buy it when budget rules; step up to Quest when it doesn't.
Full analysis: all pros & cons (7), buy if / skip if
- Far and away the cheapest bar here — around $1.30 per bar for 21 g of protein
- Best price per gram of protein in the lineup; widely available
- 21 g of mostly-complete dairy protein that clears the ~20 g MPS dose (Moore 2009)
- Low 3 g sugar and a modest 180-190 calories
- Leans heavily on maltitol and maltitol syrup — the sugar alcohol most likely to cause gas and GI upset
- Uses hydrolyzed gelatin as a binder and a less 'clean' ingredient deck than the bars above
- Artificially sweetened; chewier, more processed taste
- Budget is your binding constraint — nothing here is cheaper per gram
- You just need convenient, mostly-complete protein and don't need a clean deck
- You tolerate maltitol without GI issues
- Maltitol upsets your stomach — this leans heavily on it and maltitol syrup
- You want the cleanest ingredient deck or the least-processed taste
21 g of mostly-complete dairy protein (milk + whey isolate + whey concentrate) for about $1.30 a bar — the best price per gram here by a wide margin, and it clears the ~20 g MPS dose (Moore 2009). The caveats sit it at the bottom: it leans hard on maltitol and maltitol syrup (worst sugar alcohol for GI upset), uses hydrolyzed gelatin as a binder, and tastes more processed than the bars above. Value first, everything else second.
Pure Protein is the value play, plain and simple: 21 grams of mostly-complete dairy protein for roughly $1.30 a bar, the best price per gram of protein in this entire lineup and a fraction of what David or Legion cost. If budget is your binding constraint and you just need convenient protein, it does the job. The honest caveats are why it sits at the bottom rather than the top: it leans hard on maltitol and maltitol syrup — the sugar alcohol most likely to cause gas and stomach upset — uses hydrolyzed gelatin as a binder, and tastes more processed than the bars above it. For the cheapest 20-plus grams in bar form, though, nothing here beats it on cost.

If This Doesn’t Fit — Try These
02Quest Protein Bar
Quest is the bar most people should default to, and it earns that: 21 grams of genuinely complete protein from whey and milk isolate with no collagen padding, just 1 gram of sugar and 4 grams of net carbs, in flavors you can find at virtually any store.
07Built Bar Coconut
Built is the bar for when you want something that eats like a candy bar but barely touches your calorie budget: a light, marshmallowy nougat dipped in real chocolate at only about 130 calories, carrying 17 grams of complete whey-isolate protein.
03ONE Protein Bar
ONE is the bar to reach for when you want dessert and protein in the same wrapper: 20 grams of complete whey and milk isolate with just 1 gram of sugar, in flavors like Birthday Cake and Maple Glazed Doughnut that genuinely taste like the thing they're named after, with a soft candy-bar chew most bars can't match.
Quick Answers
Is Pure Protein's 21 g real protein?
Mostly. The bulk is complete dairy protein — milk, whey isolate and whey concentrate — which is genuine and usable. But hydrolyzed gelatin, an incomplete protein, is used as a binder, so a small share of the 21 g is padding. The majority does real muscle work; the number is just slightly softer than it looks.
Why is it ranked last if the protein and price are good?
Because ingredient quality is weighted 30%, and Pure Protein's deck is the weakest here — heavy maltitol and maltitol syrup plus a gelatin binder. On this page, quality outranks price, which is only a tie-breaker, so a great price can't lift a bottom-tier ingredient deck above better-made bars.
Will the maltitol bother my stomach?
It's the most likely to. Pure Protein leans on maltitol and maltitol syrup, the sugar alcohol most associated with gas and GI distress. If you tolerate sugar alcohols fine, it's a non-issue; if you're sensitive, this is the bar most likely to cause trouble.
Is it worth buying over Quest?
Only if budget is the deciding factor. Pure Protein is about $1.30 a bar versus Quest's ~$2.10, so it wins on pure cost. But Quest gives you complete protein with no gelatin binder, no maltitol and a cleaner carb story for less than a dollar more — the better bar if you can stretch to it.
