3Detected Excipients

Detected Excipients Breakdown:

SucralosePermitted with Warnings

Health Concern: Eruminates up to 50% of beneficial gut bacteria (Bifidobacteria) and forms toxic chloropropanols under digestive heat and acidity.

Absorption Impact: Triggers gut dysbiosis and impairs glucose tolerance.

Acesulfame Potassium (Ace-K)Permitted with Warnings

Health Concern: Manufactured using methylene chloride, a known carcinogen. Linked in animal studies to thyroid disturbances and metabolic disruption.

Absorption Impact: Stimulates artificial insulin responses without calories.

Silicon DioxideAllowed

Health Concern: Standard silica is safe, but nanoscale silica particles (<100nm) are under active scientific review for intestinal epithelial inflammation.

Absorption Impact: Minimal at food-grade macro scales; avoid excessive daily intake.
