Protein Bar Comparison Guide
The best protein bars we carry — sorted by fitness goal and dietary need — so you can grab the right bar for your day, not just any bar.
Protein bars all look similar on the shelf, but the ingredient panel tells a different story. A muscle-building bar for a training day looks nothing like a clean, whole-food snack for the afternoon. This guide breaks down the bars stocked in our Sports Nutrition department by what you're actually trying to do.
How to pick the right bar
- Training or recovery: aim for 15–25g of protein and keep sugar under ~5g.
- Everyday snack: look for short, whole-food ingredient lists — nuts, seeds, dates, egg whites.
- Plant-based: pea, brown rice, and pumpkin protein blends deliver a complete amino profile.
- Keto or low-carb: target under 5g net carbs, with MCTs or healthy fats for satiety.
- Gluten sensitivity: look for a certified gluten-free seal, not just "wheat-free" on the label.
