Why It Works
Benefits
FANCL Internal Body Support delivers comprehensive belly fat support through clinically researched functional ingredients.
Reduces Visceral Fat Effectively
Black Ginger-derived polymethoxyflavones work by increasing noradrenaline levels, which promotes fat breakdown and consumption. Clinical research on healthy Japanese adults with BMI 24-30 showed significant reduction in visceral fat area after 12 weeks of continuous intake compared to placebo.
Clinical research (12-week study)Supports Weight & Body Fat Reduction
The combination of Bifidobacterium BB536, B-3, and N-acetylglucosamine improves gut environment and increases production of short-chain fatty acids. A 24-week study on mildly obese adults showed significant reduction in body weight compared to the control group.
Clinical research (24-week study)Improves Gut Environment
Two strains of Bifidobacterium probiotics create a favorable intestinal environment by promoting beneficial bacteria. This gut-health approach supports sustainable weight management and reduces subcutaneous abdominal fat over time.
Probiotic researchEnhances Fat Consumption
Research shows Black Ginger polymethoxyflavones can increase fat consumption during low-intensity exercise like walking. The respiratory quotient study demonstrated significantly higher fat burning with the functional ingredient compared to placebo.
Clinical researchThe Science
How It Works
Understanding the three functional mechanisms behind FANCL Internal Body Support.
Black Ginger Reduces Visceral Fat
This promotes the breakdown and consumption of stored fat, specifically targeting visceral fat. In clinical research, participants taking the functional ingredient showed reduced visceral fat area after 12 weeks compared to placebo.
Probiotics Improve Gut Environment
This promotes increased production of short-chain fatty acids, which support fat metabolism and help reduce subcutaneous abdominal fat, total body fat, and body weight.
Barrier & Release Delivery Technology
- Black Ginger begins dissolving in the stomach for quick absorption
- Acid-sensitive Bifidobacterium probiotics are protected by a barrier coating
- Probiotics release safely in the intestines
The Science
Research & Evidence
Clinical research supporting the functional ingredients in this visceral fat supplement.
Visceral Fat Reduction Study—A study published in Diabetes, Metabolic Syndrome and Obesity (2018) examined the effects of Black Ginger-derived polymethoxyflavones on visceral fat. 52 healthy Japanese adults aged 20-64 with BMI 24-30 showed statistically significant reduction in visceral fat area after 12 weeks (p<0.05).
Body Weight Reduction Study—Research published in Obesity Research (2016) studied 59 mildly obese adults aged 50-69 with BMI 25-30. After 24 weeks, the group taking Bifidobacterium and N-acetylglucosamine showed significant weight reduction compared to placebo (p<0.05).
Fat Consumption Enhancement Study—Research published in Shindan to Chiryo (2016) examined fat consumption during exercise. 12 healthy Japanese men aged 20-29 showed significantly higher fat consumption with Black Ginger polymethoxyflavones during 30 minutes of low-intensity walking (p<0.05).
Consumer Validation—Over 12 million bags sold since launch. Ranked No.1 in sales for lifestyle health supplements (source: H.B. Foods Marketing Handbook 2023-2024, Fuji Keizai). Customer reviews report improvements in digestive comfort and gradual changes in belly measurements.

Functional Ingredient Research
BLACK GINGER POLYMETHOXYFLAVONES
Black Ginger (Kaempferia parviflora) is a traditional herb used in Southeast Asia. The polymethoxyflavones extracted from it have been studied for their effects on fat metabolism. Research suggests they may increase noradrenaline, promoting fat breakdown and consumption.
Diabetes Metab Syndr Obes. 2018;11:447-458BIFIDOBACTERIUM BB536 & B-3
Bifidobacterium strains BB536 (B.longum) and B-3 (B.breve) are live probiotics that support gut health. Research indicates these strains may help improve intestinal environment and support healthy body composition when combined with N-acetylglucosamine.
Obesity Research. 2016;22(2):133-144N-ACETYLGLUCOSAMINE
N-acetylglucosamine is a naturally occurring amino sugar that works synergistically with Bifidobacterium probiotics. Studies suggest this combination may support the production of short-chain fatty acids in the gut, which are associated with healthy metabolism.
