Red Bull’s Sugar-Free Options
Red Bull offers two zero-sugar alternatives with different sweetening approaches:
Red Bull Sugarfree
- Sweeteners: Aspartame, Acesulfame K
- Calories: 10 per 8.4oz can

Red Bull Zero

Frequently Asked Questions
Is Red Bull’s sugar natural or added?
Red Bull uses sucrose (from sugar beets) and glucose, both classified as added sugars by nutritionists.
Does the sugar content vary by country?
Yes – some markets have slightly reduced sugar formulas due to local regulations. UK Red Bull contains about 10% less sugar than US versions.
Can I drink Red Bull on a keto diet?
Only the Sugarfree or Zero versions fit keto macros. The regular version’s 27g sugar exceeds typical daily keto limits.
The Bottom Line
Red Bull’s sugar content ranges from substantial (27g in small cans) to excessive (63g in large cans). While the sugar provides immediate energy, it comes with significant health tradeoffs. The sugar-free alternatives offer the same caffeine boost without the sugar crash, making them smarter choices for regular consumers. Moderation remains key – even sugar-free energy drinks should be consumed in limited quantities due to their caffeine and additive content.
