Why It Works
Benefits
Chitosan After Diet delivers comprehensive after-meal support through six carefully selected ingredients, each serving a specific function.
Fat Support with Chitosan
Chitosan (1000mg per 12 tablets) is an animal fiber derived from crab shells. When taken after meals containing oily foods, chitosan works in the digestive system to support the body's natural fat management processes. This is why Japanese consumers have trusted it for over 25 years.
25-Year Market ValidationSugar & Carb Support with Gymnema
Gymnema Sylvestre (600mg) is known as 'Gurmar' in Hindi, meaning 'sugar destroyer.' This traditional herb supports the body when consuming sweets and carbohydrates. Combined with chitosan's fat support, it provides dual-action coverage for indulgent meals.
Traditional Ayurvedic IngredientDigestive Regularity with Fiber
The formula includes Kidachi Aloe Extract (450mg) and Psyllium Husk (300mg)—both excellent sources of dietary fiber. These ingredients support healthy digestion and promote daily regularity, helping you feel comfortable after meals.
Fiber-Rich FormulaMetabolism Support with Thermogenic Capsicum
Capsicum/Red Pepper (100mg) provides natural thermogenic support, while the Mucopolysaccharide Protein Complex (350mg) offers additional support for both sweets and oily foods. B-vitamins and minerals round out this comprehensive formula.
Multi-Ingredient SynergyThe Science
How It Works
Understanding how Chitosan After Diet's six-ingredient formula supports your body after meals.
Chitosan: The Fat-Binding Fiber
How it works:
- Chitosan carries a positive electrical charge
- Dietary fats carry a negative charge
- When taken after oily meals, chitosan binds with fats in the digestive system
- This supports the body's natural fat management processes
This is why the product is called "After Diet"—it's designed to take after eating, not before.
Gymnema: The Sugar Destroyer
Known as "Gurmar" in Hindi—meaning "sugar destroyer"—this plant has an interesting property: when you chew its leaves, you temporarily can't taste sweetness.
Together with chitosan, Gymnema provides dual-action support for both fat and sugar—comprehensive coverage for indulgent meals.
