How to Judge Protein Sodas Against Fairlife

Focus on a few core details when choosing a protein soda alternative to Fairlife.

• Protein Type & Amount: Whey protein isolate absorbs faster and contains 10% more protein per serving compared to concentrate. Aim for at least 20g for muscle recovery.¹
• Macronutrient Profile: Look for options under 150 calories with minimal sugar and carbs.
• Carbonation Level: Light fizz keeps the drink refreshing without overpowering the protein.
• Availability: Prioritize products you can find at major retailers like Walmart, Amazon, and Target.
• Caffeine Content: Caffeine-free options work for any time of day and for a wider range of users.

When comparing nutrition labels, prioritize isolate content over concentrate for faster absorption and higher purity.¹ After you pick a protein soda, chill it thoroughly before drinking, because colder temperatures enhance both carbonation and flavor.
