Heritage Tea Company

From ITO EN, Japan's leading tea company, using proprietary manufacturing technology for high-purity catechin extracts.

Best For

Individuals with higher-than-normal BMI seeking natural support for body fat reduction through green tea catechins.

Trusted Japanese Brand

ITO EN is Japan's most recognized tea brand, with decades of expertise in green tea formulation.

Why It Works

Benefits

Gallic-type catechin delivers dual-action support for body fat reduction through scientifically studied mechanisms.

1

Inhibits Fat Absorption

Gallic-type catechin blocks pancreatic lipase, the digestive enzyme responsible for breaking down dietary fats. By inhibiting this enzyme's activity, the catechin prevents fat from being absorbed in the small intestine and increases fat excretion.

Clinically validated mechanism
2

Activates Fat Burning

Beyond blocking fat absorption, gallic-type catechin activates beta-oxidation enzymes in the liver and muscles, enhancing your body's natural fat-burning processes. This targets visceral and subcutaneous fat deposits.

Research-backed ingredient
3

Reduces Post-Meal Triglycerides

The compound helps reduce post-meal blood triglyceride levels, contributing to overall metabolic health. Particularly beneficial when taking the supplement during high-calorie or high-fat meals.

4

Concentrated Green Tea Benefits

Get the equivalent of 8 cups of brewed green tea in just 6 small tablets. ITO EN's proprietary extraction technology delivers high-purity catechin that would be difficult to obtain from drinking tea alone.

Patented manufacturing process

The Science

How It Works

Understanding how gallic-type catechin supports body fat reduction through dual mechanisms.

Fat Absorption Inhibition

Fat Absorption Inhibition

Gallic-type catechin works by blocking lipase enzyme, preventing fat from being broken down and absorbed.

Key mechanism:
  • Fat enters small intestine
  • Catechin blocks lipase enzyme activity
  • Undigested fat passes through and is excreted
  • 8-12 weeks shows measurable fat reduction
Proprietary Catechin Extraction

Proprietary Catechin Extraction

ITO EN's patented technology (Patent No. 2703241, 3052172, 3052174) extracts high-purity, high-concentration catechin from green tea leaves.

Quality features:
  • Personal quality verification at source locations
  • Higher purity than standard extracts
  • 394mg gallic-type catechin per daily serving
Concentrated Tablet Delivery

Concentrated Tablet Delivery

Each 8mm tablet concentrates the power of green tea catechins.

Benefits:
  • 6 tablets = 8 cups of green tea catechins
  • No bitter taste of concentrated tea
  • Easy to take with meals

The Science

Research & Evidence

This catechin supplement is registered as a Functional Food with Health Claims, meaning its health benefits have been reported to Japan's Consumer Affairs Agency.

Clinical Evidence for Body Fat Reduction

Clinical Evidence for Body Fat Reduction—Comparison study tracking abdominal total fat area changes over 12 weeks. Participants consuming gallic-type catechin showed decreased body fat compared to control group at 4, 8, and 12-week intervals.

How Gallate-Type Catechin Works

How Gallate-Type Catechin Works—Gallate-type catechins inhibit the activity of lipase, a digestive enzyme that breaks down dietary fat. By blocking lipase, less fat is absorbed during digestion—the unabsorbed fat is naturally excreted from the body.

Questions

Frequently Asked Questions

Catechin supplements contain concentrated polyphenols extracted from green tea. Gallic-type catechin specifically inhibits lipase, the enzyme that breaks down dietary fat for absorption.

By blocking this enzyme, less fat is absorbed during digestion, and more is excreted. Additionally, catechins activate fat-burning enzymes in the liver, supporting metabolic health.
Both matcha and catechin supplements provide green tea polyphenols, but in different concentrations.

This ITO EN supplement delivers 394mg of gallic-type catechin per serving, equivalent to about 8 cups of brewed green tea. Achieving this through matcha alone would require consuming large amounts daily.
Look for supplements registered as Functional Foods in Japan, like this ITO EN product (F350), which indicates the health claims have been reported to regulators.
