Quick Ranking Table: 2026 Protein Soda Taste Test Results

Complete Rankings: Worst to Best Protein Sodas

#10: Koia Protein Pop Sour Squeeze – Gritty Disappointment

This plant-based can packs 10g pea protein into a lemon-lime base, yet the overall experience feels harsh. The flavor hits like an overly sour candy blast, with citrus notes that linger longer than you want. Pea protein adds clear grittiness that breaks up the carbonation and leaves the drink cloudy with weak fizz. At 70 calories and 2g sugar, the macros look fine, but the earthy plant aftertaste still dominates every sip.

#9: Genius Gourmet Blue Raspberry Lemonade – Too Thick for Soda

This Costco exclusive squeezes 30g protein into a 12oz can, which sounds powerful on paper. In reality, it drinks more like a dense protein shake than a refreshing soda. The blue raspberry flavor tastes like a typical sports drink and stays fairly pleasant. The texture creates the real issue, since it feels syrupy, heavy, and only lightly carbonated, with bubbles that fade fast. The high protein count sacrifices drinkability and turns each can into a chore.

#8: Protein2O Strawberry – Watery and Flat

This hydrolyzed whey drink promises easy absorption but delivers a thin, diluted experience. The strawberry flavor barely shows up and tastes closer to lightly scented water than a real beverage. The clear appearance looks appealing and the liquid stays smooth, with no grit at all. Carbonation remains so faint that it feels almost still. You finish the bottle and still question whether you actually drank a protein product.

#7: Barebells Wild Strawberry – Sweet but Gritty

This Swedish option combines 20g protein with added energy ingredients, creating a protein and energy hybrid. The wild strawberry flavor hits hard with intense candy-level sweetness that divides opinions. Carbonation feels solid at first, yet a subtle grit creeps in and becomes more noticeable as you keep sipping. The energy lift feels nice for busy days. Overall, it lands closer to a sugary treat than a clean, everyday protein drink.

#6: Don’t Quit! Orange – Decent Fizz, Balanced Finish

This clear, zero-sugar orange soda delivers 15g protein and a surprisingly classic soda feel. Carbonation comes through strong, and the first sip tastes bright and citrusy. The finish stays pleasant and encourages another drink. The whey concentrate base supports decent protein intake while still keeping the texture fairly smooth. It offers a well-balanced experience that feels familiar for traditional soda fans.

#5: Clean Simple Eats Cherry Lime – Tangy but Lacking Depth

This 20g whey isolate drink nails clarity and smoothness, with no grit or chalk at all. The cherry lime flavor brings a fun, tangy kick that avoids tasting overly fake. Carbonation feels light yet still refreshing. The flavor profile never fully develops, so it does not create that strong “reach for another can” pull. It performs well technically but stops short of feeling memorable.

#4: Koia Pink Twist – Fizzy Plant Power

Koia Pink Twist shows how plant protein soda can work when handled carefully. The 10g pea protein blends in better here, which keeps grittiness low and carbonation lively. The watermelon flavor tastes surprisingly authentic and refreshing for a plant-based drink. A mild earthy note still lingers in the background, as with most pea proteins. At 70 calories with added fiber, it offers a nutritionally strong choice that proves plant-based soda can be enjoyable.

#3: Propel Clear Pear Apple – Light and Refreshing

PepsiCo’s 2026 entry delivers 20g whey protein in a drink that feels closer to sparkling water than a shake. The pear apple flavor tastes unique, crisp, and clearly artificial, yet still refreshing. Texture stays smooth with steady carbonation that never overwhelms. The light body makes it easy to drink, especially for people who dislike heavy shakes. Artificial notes remain noticeable, but the overall experience feels clean and simple.

#2: Starbucks Coffee & Protein Caffè – Coffee Excellence

This can targets coffee lovers who want protein without giving up their daily ritual. It delivers 22g complete protein wrapped in real espresso flavor with only mild protein hints. The texture feels smooth and creamy while still avoiding that thick shake heaviness. Gentle carbonation adds a surprising twist that keeps each sip interesting. With 2g sugar and added prebiotic fiber, it functions as a balanced hybrid between coffee drink and protein support.

#1: Bucked Up Banana Pineapple – Soda Perfection

Bucked Up Banana Pineapple sets the standard for what protein soda can be. Each can delivers 25g of 100% whey protein isolate in a crystal-clear, sharply carbonated drink that tastes like a premium tropical energy beverage. The flavor brings real banana sweetness balanced by bright pineapple acidity, with no fake or chemical aftertaste.
