Why It Works
Benefits
FANCL Adult Calorie Limit delivers multi-faceted dietary support through four clinically studied functional ingredients.
Supports Carb and Sugar Management
Mulberry Leaf iminosugar and Chitosan work together to help suppress the absorption of sugar from meals. A clinical trial with 50 healthy Japanese adults demonstrated that the functional ingredients significantly suppressed post-meal blood sugar levels compared to the control group, with statistical significance (P<0.05 to P<0.001).
Clinically tested (published study)Helps Block Dietary Fat Absorption
Tea Flower saponin and Chitosan support the suppression of fat absorption from meals. In a clinical trial with 59 healthy Japanese adults, the combination significantly suppressed post-meal blood triglyceride levels compared to the control group (P<0.01 to P<0.001).
Clinically tested (published study)Supports Fat Metabolism
Black Ginger-derived polymethoxyflavone (12mg per serving) has been reported to help fat metabolism and make it easier for the body to consume fat. Research showed that participants taking black ginger extract had lower respiratory quotient values, indicating greater fat utilization during both rest and light activity.
Research-backed ingredientMay Help Reduce Abdominal Fat
For those with elevated BMI (24-30), Black Ginger-derived polymethoxyflavone has been reported to help reduce total abdominal fat area. A 12-week study with 52 participants showed significant reduction in abdominal fat area as measured by CT scan.
Clinically studied (12-week trial)The Science
How It Works
Understanding how FANCL Adult Calorie Limit's four functional ingredients support your body's dietary and metabolic processes.
Sugar & Fat Absorption Blocking Mechanism
- Mulberry Leaf iminosugar - helps interfere with sugar decomposition
- Chitosan (derived from crab shell) - helps block fat decomposition
- Tea Flower saponin - provides additional fat-blocking support
This patented three-ingredient combination helps suppress both sugar and fat absorption from meals.
Black Ginger Fat Metabolism Support
Research indicates that polymethoxyflavone may enhance lipid oxidation, meaning the body uses more fat for energy during daily activities.
The Comprehensive Approach
- Suppressing sugar absorption from meals
- Suppressing fat absorption from meals
- Supporting fat metabolism to help consume fat more easily
- For those with elevated BMI, potentially helping reduce abdominal fat
Combined with proper diet, moderate exercise, and adequate sleep, this supplement provides comprehensive support.

Ingredient Research Highlights
MULBERRY LEAF IMINOSUGAR
Mulberry leaf contains iminosugar compounds that have been studied for their role in sugar metabolism. Research suggests these compounds may help interfere with the enzymatic breakdown of complex sugars, thereby supporting the management of post-meal blood sugar levels.
Functional Food ingredient research; clinical trial published in Pharmacology and TherapeuticsBLACK GINGER POLYMETHOXYFLAVONE
Black Ginger (Kaempferia parviflora) is a plant native to Thailand, also cultivated in Japan. Its polymethoxyflavone compounds have been studied for supporting fat metabolism. Research reports suggest these compounds may enhance lipid oxidation and support the reduction of abdominal fat in individuals with elevated BMI.
Published research in Pharmacology and Therapeutics; Diabetes, Metabolic Syndrome and ObesityCHITOSAN
Chitosan is derived from the shells of crustaceans (crab). It has been studied as a dietary fiber that may help bind dietary fats in the digestive tract, potentially reducing fat absorption. The chitosan in this product uses a patented formulation for improved solubility.
