When to Choose Bulletproof Chocolate Chip Cookie Dough Collagen Bar
Keto and biohacking enthusiasts who want MCT oil and collagen in a low-sugar bar
Bulletproof targets the keto-biohacking crowd with MCT oil, grass-fed collagen, and only 2g sugar. The stevia sweetening is natural but divisive. Like all collagen bars, the incomplete amino acid profile is a limitation. Best for those already in the Bulletproof ecosystem.
Strengths
- Only 2g sugar per bar with grass-fed collagen and MCT oil for sustained energy
- Stevia leaf extract is a natural sweetener — no artificial sweeteners used
- Grass-fed collagen sourced from pasture-raised cattle
Limitations
- Only 11g protein per bar — on the lower end for a protein bar
- Stevia aftertaste can be polarizing for some consumers
- Collagen provides incomplete amino acid profile without tryptophan
When to Choose Pure Protein Chocolate Peanut Butter Bar
Budget buyers who want the most protein per dollar and are not concerned about artificial sweeteners
Pure Protein wins on value — 20g protein at ~$1.33/bar is the cheapest protein per gram in this comparison. The whey blend is effective. But sucralose and likely artificial flavors earn it some of the lowest ingredient scores. This is the bar for those who count macros and dollars, not ingredient labels.
Strengths
- Best value in this comparison at ~$1.33/bar with 20g protein per bar
- Whey protein blend provides good bioavailability and complete amino acids
- Widely available at nearly every grocery store, convenience store, and pharmacy
Limitations
- Contains sucralose — a controversial artificial sweetener penalized in our scoring
- Likely contains artificial flavors alongside the sucralose sweetening
- Minimal transparency about sourcing, testing, or manufacturing practices
