Evidence-Based Formulation
Decades of peer-reviewed research support the metabolic benefits of soluble fiber. Here's what the science says about our core ingredients.

African Mango (Irvingia gabonensis) fruits on tree branch, showing the natural source of this weight loss ingredient
Clinical trial participants taking 150mg twice daily lost an average of 28 lbs (12.8 kg) with 6.4-inch waist reduction over 10 weeks.

Allulose reduces blood glucose AUC (area under the curve—your total glucose exposure over time) and stimulates GLP-1 release from intestinal L-cells.

Key Finding
Participants taking 150mg twice daily experienced average weight loss of 28 lbs (12.8 kg), 6.4-inch waist reduction, and 6.3% decrease in body fat over 10 weeks.
Methodology
Double-blind, randomized, placebo-controlled trial with 102 overweight adults.
Common Questions
Allulose is a rare sugar that tastes sweet but isn't metabolized like regular sugar. Clinical studies show it reduces blood glucose area under the curve (AUC) by about 14%. AUC measures your total glucose exposure over time—a lower AUC means more stable energy levels and fewer crashes. Allulose also stimulates GLP-1 release from intestinal L-cells, the same satiety hormone pathway targeted by prescription weight-loss medications.
