60 out of 100

EGCg Green Tea Extract 400 mg offers green-tea compounds with antioxidant activity, while its practical benefits for skin and healthy aging remain uncertain.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality40

The green-tea compounds are identified, but preparation quality cannot be judged confidently. Differing quantity declarations also prevent a reliable combined amount.

Ingredient Transparency100

The amount, named compounds and mixture breakdown are disclosed. Those details make the contents easier to compare, though the different quantity declarations should not simply be added together.

Value For Money40

Value for the active green-tea compounds remains uncertain. Differing quantity declarations prevent a reliable combined cost comparison.

Customer Satisfaction90

Customer feedback is favorable across a very large review pool. That gives a broad picture of satisfaction without establishing skin or longevity benefits.

Product Focus45

The single green-tea ingredient keeps the formula simple. Antioxidant activity does not establish longer life or routine skin protection.

Green tea provides compounds with antioxidant activity, but dietary tea findings and laboratory mechanisms do not establish a longevity benefit from this extract. Tea powder, total extract and active EGCG amounts are not interchangeable.

How this product is rated for Longevity

Ingredient fit94

Green Tea provide the main connection. The saved amount comparison should not be interpreted as proof of anti-aging effectiveness.
Goal fit
Green Tea provide the relevant ingredient focus; the product is also linked to other goals.
Dose adequacy
The relevant amounts meet the saved comparison amounts; this does not establish a proven anti-aging dose.

Pathways60

The main connection is antioxidant defence; broader aging outcomes do not follow from that mechanism.
Depth
The main supplied connection is antioxidant defence, through Green Tea. This mechanism does not establish a clinical anti-aging effect.
Breadth
Only one mechanism reaches the saved coverage threshold; the connection remains narrow rather than covering multiple aspects of aging.

Evidence82

The saved finding recognizes ingredient evidence and preparation matches, while the human outcomes remain bounded by the qualifications described above.
Evidence strength
Green Tea anchors the saved evidence finding, but the supported outcome remains limited by the ingredient-specific human findings.
Studied preparation
The ingredients used for this finding match preparations recognized in the saved comparison; this does not remove the limits of their clinical evidence.

Formulation logic100

The supplied checks identify no missing required partner or matched conflict. Amount thresholds describe the saved comparison and do not establish clinical effectiveness.
Partner coverage
The relevant ingredients can act independently or have their required partner; this does not demonstrate an added benefit from combining them.
Conflicts
No conflict was identified by the supplied checks; this is a limited formulation finding, not a general safety conclusion.
Effective doses
The included ingredients meet the saved amount threshold, which is a comparison convention rather than a proven minimum effective dose.

Green Tea · 50 mg

Oral green-tea catechins have been investigated for UV-related skin responses, with mixed results and a trial that did not support UV inflammatory protection. The supplied serving declares 450 mg green tea and receives partial amount recognition. Total extract mass does not identify the tested catechin exposure, so it cannot establish matched preparation effects or routine skin protection.

How this product is rated for Skin Health

Ingredient fit90

Green Tea supplies the leading saved contribution. The amount comparison remains partial across the counted ingredients.
Goal fit
Green Tea provides the focused skin-related connection, though the product is also linked to other goals.
Dose adequacy
The counted amounts receive partial overall recognition in the saved comparison, without establishing the same effects as a study regimen.

Pathways56

The saved findings are strongest in uv antioxidant defence. Only this category reaches the breadth threshold.
Depth
The strongest saved contribution is assigned to uv antioxidant defence; this category does not itself demonstrate a clinical skin improvement.
Breadth
Only uv antioxidant defence reaches the saved breadth threshold, leaving the findings concentrated in one category.

Evidence89

Green tea leads the saved evidence comparison, while mixed oral catechin findings and unresolved preparation equivalence limit the benefit claim.
Evidence strength
Green tea leads the saved evidence comparison, while mixed oral catechin findings and unresolved preparation equivalence limit the benefit claim.
Studied preparation
The saved finding recognizes the preparation, but generic green-tea mass does not establish the tested catechin exposure.

Formulation logic100

Partner requirements are met, no configured conflict is matched and the counted amounts meet the saved minimum comparison.
Partner coverage
No unmet partner requirement is recorded for the counted ingredients; this does not establish extra benefit from combining them.
Conflicts
No configured ingredient conflict is matched in the supplied facts.
Effective doses
All counted ingredients meet the saved minimum amount comparison; this does not establish a clinically effective skin dose.
