Vegan Protein Powder Without Artificial Sweeteners
Artificial sweeteners like sucralose, aspartame, and acesulfame-K keep calories low, yet emerging human data show they can reshape the gut microbiome and nudge glucose tolerance off course. A 2022 randomized crossover trial found healthy adults given non-nutritive sweeteners developed microbiome shifts that predicted impaired glycemic responses within two weeks. *
Long-term safety reviews still rate these additives as “generally recognized as safe,” but those verdicts rest on toxicology, not athletic performance or gut comfort. Consumer journalism echoes the uncertainty, highlighting sucralose links to gastrointestinal distress and insulin confusion even though evidence is mixed. *
If you want sweetness without synthetic lab work, stevia and monk fruit deliver. EFSA’s latest assessment reconfirmed steviol glycosides safe at 4 mg per kilo body weight daily, and monk-fruit mogrosides carry GRAS status with no reported metabolic downside. *
Labels hide the truth in plain sight. Scan the ingredient deck for sucralose, acesulfame potassium, or “artificial flavors.” Powders sweetened only with stevia, monk fruit, or left unflavored dodge the synthetic list entirely and still mix like dessert when blended with fruit or nut milk.
