Why Protein Soda Beats Traditional Shakes in 2026
Protein sodas give a lighter, more refreshing experience than thick shakes like Premier Protein and Muscle Milk. The carbonated format avoids a heavy, milky mouthfeel that can reduce appetite and make daily use harder. Clinical studies show protein sodas deliver 109% higher plasma BCAAs and stronger appetite suppression than traditional shakes. Ready-to-drink cans remove mixing steps and support faster absorption through a clear liquid base. Carbonated protein drinks also tend to cause less digestive discomfort, which encourages consistent intake across the week.
How Caffeine-Free Protein Soda Helps GLP-1 Users
GLP-1 medication users often struggle to eat enough protein because their appetite drops and solid foods feel harder to finish. Adults generally need about 1.2g of protein per kg of body weight daily to protect muscle, with higher targets during weight loss phases. Bucked Up’s 25g whey protein isolate can cover close to half of many people’s daily needs in one can. The clear, carbonated drink works well for those who prefer sipping liquids instead of chewing large meals. Its complete amino acid profile supports muscle preservation, and the caffeine-free formula fits any schedule, including evenings.
