What the AI looks for in Sports Nutrition Endurance & Energy Bars
- Carbohydrate per serving
- Plan roughly 30–60 g of carbohydrate per hour for efforts over about an hour, and size bar intake to fit that. This is the standard sports-nutrition fueling guideline. Bars are one carb source within it.
- Low fat and fiber during exercise
- Use bars with low fat and fiber during exercise, and save fattier, fiber-rich bars for before or after. Fat and fiber slow digestion and can cause GI distress at intensity.
- Ease of eating
- Choose thin or soft formats if you will eat while moving. Dense bars are hard to chew and swallow when breathing hard.
Brands that matter
- Clif: The reference oat-based energy bar.
- Honey Stinger: Honey-based waffles and bars for mid-activity fueling.
- Maurten: Endurance-focused solid fuel aimed at racing athletes.
- Skratch Labs: Endurance nutrition brand with real-food-style products.
What to avoid
- Protein bars marketed as 'energy' that are mostly protein and fiber.
- Chocolate-coated bars for warm-weather efforts.
