You may remember my original protein bar review video from 2023. A lot has changed since then—not just in the world of food science, but in the protein bar market itself. New bars have emerged, brands have reformulated, and taste has (thankfully) improved across the board. So I decided it was time to revisit the topic.
This time, we’re not just reviewing the bars you commonly find at your local grocery store—we’re covering 15 of the most popular, cult-favorite, and widely sought-after protein bars of 2025. Each bar is judged on three core criteria:
- Macros – Does it pass the Protein Test (protein grams × 10 ≤ total calories)? Is it a lean source of protein (≤10g fat, <4g saturated fat)?
- Taste – Does it actually taste good?
- Ingredients – Are the proteins bioavailable? Any red flags?
Let’s break down each bar, then I’ll reveal my Top 5 picks.
1. Power Crunch
- Calories: 250
- Protein: 13g
- Fiber: 1g
- Verdict: Fails the protein test. Low fiber. High fat. But it tastes like a peanut butter fudge wafer. Delicious, not nutritious.
2. Pure Protein
- Calories: 200
- Protein: 20g
- Fiber: 1g
- Verdict: Passes the protein test. Lean protein source. Ingredients are solid. Taste? Not my favorite, but many love it. Easy to find at big box stores.
3. Quest Protein Bar
- Calories: 190
- Protein: 20g
- Fiber: 11g
- Verdict: Passes protein test. High fiber. Lean. Bioavailable protein. People complain about the texture (it’s stiff), but 10 seconds in the microwave fixes that. Still one of the OGs that holds up.
4. Fit Crunch
- Calories: 190
- Protein: 16g
- Fiber: 1g
- Verdict: Fails the protein test. Only 12g of bioavailable protein. Macros and ingredients aren’t up to snuff, but wow—it tastes like a candy bar.
5. Clif Builder’s Bar
- Calories: 280
- Protein: 20g
- Fiber: 4g
- Verdict: Fails protein test. High in carbs and fat. Not a lean protein source. Soy-based but bioavailable. Taste? Great. Macros? Not great.
6. Think!
- Calories: 240
- Protein: 20g
- Fiber: 1g
- Verdict: Fails on all fronts. Not a lean protein source. Macros suck. Taste is even worse. Hard skip.
7. ONE Bar
- Calories: ~210 (varies)
- Protein: ~20g (varies)
- Fiber: ~7g
- Verdict: Mixed bag. Some flavors pass the test; others don’t. Always check the label. Generally great taste and solid fiber.
8. Barebells
- Calories: 200
- Protein: 20g
- Fiber: 3g
- Verdict: Narrowly passes protein test. Lean. Some collagen, so bioavailability varies by flavor. Taste? Candy-bar level. My top pick.
9. Built Puffs
- Calories: Varies
- Protein: 17g (non-bioavailable)
- Verdict: Not a true protein bar. Entirely collagen-based, so it doesn’t support muscle protein synthesis. Tastes great—but not functional.
10. Anabar
- Calories: 290
- Protein: 20g
- Sugar: 21g
- Verdict: Protein dessert, not a bar. Great taste, terrible macros. 75% bioavailable protein. High sugar, low fiber. More dessert than supplement.
11. Grenade
- Calories: 250
- Protein: 21g
- Fiber: 10g
- Verdict: Fails the protein test. High in fat. Hard to get in the U.S. Some collagen content. Taste? Pretty good, but not worth the international shipping.
12. David Bar
- Calories: 150
- Protein: 28g
- Fiber: Minimal
- Verdict: Shatters the protein test. Incredible macros. All bioavailable despite collagen content, thanks to food science innovation. Taste is hit or miss, but the formula is next-level.
13. Legion Protein Bar
- Calories: 240
- Protein: 20g
- Fiber: 9g
- Verdict: Fails the protein test. Not lean. Good ingredients. But tastes worse than a Quest bar and is way too stiff. Hard pass.
14. 1st Phorm Level-1
- Calories: 260
- Protein: 20g
- Fiber: 1g
- Verdict: Fails the protein test. More fat than protein. Tastes amazing (especially the peanut butter flavor), but doesn’t deliver functionally.
15. Redcon MRE Bar
- Calories: 260
- Protein: 20g
- Fiber: 3g
- Verdict: Fails protein test. Protein from whole food sources (beef, chicken, salmon, egg, etc.), which is interesting. But taste is mid, macros are off. Gimmick doesn’t pay off.

Final Thoughts
Whether you’re focused on lean muscle gain, weight loss, or just trying to hit your protein goals on the go, picking the right bar matters. Remember to:
- Check the back of the label
- Prioritize bioavailable protein
- Don’t get fooled by candy bar disguises
Food science has come a long way—but so have marketing tricks.
