Analysis

The label identifies a 400 mg green tea extract with catechins and EGCG, plus a 50 mg decaffeinated green tea component. The stated active amount makes dose comparison much easier than with unstandardized products.

Decaffeinated positioning supports low stimulant exposure and the one-capsule serving is practical. No phospholipid or other enhanced-delivery system is included.

It fits experienced adults seeking a high, clearly quantified EGCG serving. People new to green tea extracts may prefer a lower amount to assess tolerance.

Who is it for
  • Adults seeking a high disclosed EGCG amount
  • Caffeine-sensitive green tea users
  • Experienced catechin supplement users
Best for
  • High-potency EGCG supplementation
  • Low-stimulant green tea use
  • One-capsule active dosing

Pros

  • Discloses 400 mg EGCG
  • Identifies catechins
  • Uses decaffeinated green tea
  • Strong value for the active amount

Cons

  • High amount may be hard to tolerate
  • No enhanced-absorption delivery
  • Basic capsule formulation
  • May be excessive for first-time users

Warnings

  • Take the 400 mg EGCG serving with food because high-dose green tea extract is more likely to cause nausea or liver stress when used fasting.
  • Do not stack it with other concentrated green tea or EGCG supplements without accounting for total exposure.
  • Separate the capsule from iron supplements because catechins can reduce iron absorption.

Nutrient quality

90 Highest impact

Decaffeinated extract and named EGCG provide strong form and stimulant clarity. The active amount is substantial but remains below the higher-risk range when used with food.

.

Ingredient transparency

79 High impact

Green-tea, catechin, EGCG, and decaffeinated status are all stated. Repeated full-amount entries may overlap, while directions and capsule ingredients are missing.

.

Customer satisfaction

71 High impact

The supplied aggregate rating indicates strong customer satisfaction. Specific comments are unavailable, so complaint patterns and intended-use fit cannot be verified.

.

Value for money

95 Highest impact

Strong active disclosure and a modest serving cost create excellent value. Basic capsule delivery is the only notable trade-off.

Decaffeinated green tea extract provides a clearly disclosed 400 mg EGCG amount for antioxidant and metabolic support. Human evidence supports selected cardiovascular and metabolic markers, but not a broad claim of slower aging.

The capsule lacks specialized absorption technology, yet active-marker and stimulant disclosure are strong. Concentrated EGCG may irritate the stomach and has a greater liver-injury concern when taken fasting, so taking it with food is the safer practical choice.

Green-tea catechins and EGCG directly target oxidative and inflammatory signaling. Human evidence supports standardized green-tea extracts, though benefits depend on verified active yield and tolerability.

The 400 mg extract amount is substantial and the label associates it with catechins and EGCG. Species and active descriptors are provided, but repeated 400 mg entries make the exact EGCG share unclear. Concentrated green-tea extract can cause nausea and has been linked to liver injury in susceptible users, especially when taken on an empty stomach.

Green tea catechins provide antioxidant and inflammation-balancing support that may help protect skin from environmental stress. The substantial extract amount and explicit EGCG identification make the active contribution easy to assess.

Evidence supports modest help with photoprotection and skin condition, but oral green tea is not a complete skin formula. Concentrated green tea extract can rarely harm the liver, with risk more concerning when high-EGCG servings are taken while fasting.

Decaffeinated EGCG may support fat oxidation and metabolic signaling. Removing caffeine improves stimulant tolerance but weakens the most established thermogenic combination.

Green Tea · 50 mg

A concentrated decaffeinated green-tea extract supports antioxidant protection but offers limited immediate focus support without theanine or caffeine. Human cognitive evidence for isolated EGCG is less consistent than evidence for established memory or attention ingredients.

The disclosed 400 mg EGCG amount is substantial and falls within the preferred active range. EGCG and decaffeination are clearly identified, but no absorption-enhancing delivery is disclosed. The 400 mg EGCG amount may increase liver-stress risk when taken while fasting or by people with existing liver concerns.
