Product analysis
Green Tea Extract 400 mg supplies plant compounds with antioxidant activity and may briefly increase the energy your body uses. Unclear amounts of its key compounds make the size of any benefit difficult to predict.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality40
Named vitamin C and green tea constituents do not establish ingredient quality. The extract’s unclear breakdown limits a meaningful comparison with other preparations.
Ingredient Transparency80
Ingredient amounts and named forms are stated. The green tea compound breakdown is missing, so the extract amount cannot show the exact amounts of its key constituents.
Value For Money40
Value for money remains uncertain. Without a clear amount of the key green tea compounds, a useful cost comparison is difficult.
Customer Satisfaction89
Customer ratings are positive across a large review base. The broad feedback supports a clearer view of satisfaction without establishing health benefits.
Product Focus72
The main connection is to antioxidant activity, with a possible small and temporary effect on energy use. Skin findings are mixed, and the extract does not establish improved cognition, longer life or lasting fat loss.

Vitamin C · 60 mgGreen Tea · 400 mg
Green tea is connected to research on skin responses to UV exposure, but oral findings are mixed. The 400 mg extract serving does not disclose a preparation-equivalent catechin exposure. Vitamin C supports collagen formation when intake is low, although its 60 mg serving falls below the saved threshold for consideration. The findings therefore center on green tea without establishing broader hydration or structural benefits.
How this product is rated for Skin Health

Breadth
Only UV antioxidant defence reaches the breadth threshold.
Evidence89
Green tea drives the evidence finding, while mixed oral results limit expectations.
Evidence strength
Green tea drives the evidence finding, while mixed oral results limit expectations.
Studied preparation
The saved finding accepts green tea's preparation, while generic extract mass does not establish the tested catechin exposure.
Formulation logic100
The credited ingredients have no unmet partner requirement or recorded conflict. Their amounts pass the saved minimum threshold, which does not establish clinical effectiveness.
Partner coverage
Every credited ingredient can stand alone or has its required partner; this does not imply added benefit from combining ingredients.
Conflicts
No matched formulation conflict is recorded in the supplied findings.
Effective doses
All credited ingredients pass the saved minimum amount threshold; this is not proof of a clinically effective dose.
Impact
Moderate effect
Green Tea · 400 mg
Green tea's catechins and caffeine may produce a small, temporary increase in the energy your body uses. The extract here doesn't identify a specific EGCG preparation, and its caffeine is described only as an upper limit. That makes the size of any effect uncertain; the extract amount can't be treated as an exact catechin or caffeine amount. A temporary increase in energy use doesn't imply lasting fat loss.
How this product is rated for Metabolism Support
Ingredient fit66
Green tea is relevant to temporary energy use, but the extract identity and active amounts limit expectations.
Goal fit
Green tea have a connection to normal energy processes, with uncertain temporary effects on energy use.
Dose adequacy
The serving contains 400 mg green tea extract; this is extract mass, not an exact EGCG or caffeine amount.
Pathways13
The connection is mainly to temporary stimulation of energy use. Broad effects across several ways of increasing energy expenditure remain unclear.
Depth
Green tea relates mainly to temporary stimulation of energy use.
Breadth
Several distinct ways of increasing energy expenditure are not clearly supported for this extract.
Evidence23
The exact green tea preparation is unresolved, which limits how confidently its effects transfer to this serving.
Evidence strength
A small temporary effect on energy use is possible, but the effect beyond caffeine is uncertain.
Studied preparation
The precise green tea preparation is unresolved, so effects of a defined EGCG preparation cannot be assumed.
Formulation logic100
No particular ingredient conflict or missing required partner is identified.
Partner coverage
No missing required ingredient partner is identified.
Conflicts
No particular ingredient conflict is identified.
Effective doses
The 400 mg extract serving has a known material amount, while its exact EGCG and caffeine amounts remain unresolved.

Vitamin C · 60 mgGreen Tea · 400 mg
Green tea contributes the product's main connection to oxidative stress. The supplied evidence found most inflammatory markers unchanged, with a limited serum-amyloid signal in people with metabolic syndrome. Green tea extract receives a contribution in the saved findings, but its material amount does not establish an equivalent EGCG amount or a preparation-matched clinical benefit.
How this product is rated for Inflammation
Ingredient fit86
Green tea is the main relevant ingredient. The declared amount supports the saved contribution, subject to the ingredient’s specific evidence limits.
Goal fit
Green tea provides the main relevant ingredient focus, with a relatively focused formula.
Dose adequacy
The declared green tea material amount contributes in the saved findings, but does not establish an equivalent EGCG dose.
Pathways41
The contribution is concentrated in oxidative and mitochondrial stress, rather than broad coverage of the assessed inflammatory routes.
Depth
Green tea supplies the main contribution in oxidative and mitochondrial stress.
Breadth
Only oxidative and mitochondrial stress reaches the coverage threshold; the other assessed routes add no coverage.
Evidence73
Green tea supplies the evidence connection; the accepted preparation does not resolve the limited clinical findings or EGCG equivalence.
Evidence strength
Green tea leads the evidence finding, although most markers were unchanged in the supplied metabolic-syndrome trial.
Studied preparation
The saved findings accept the preparation, although the supplied science does not establish material-to-EGCG equivalence.
Formulation logic100
Green tea can contribute independently, with no configured ingredient conflict identified.
Partner coverage
Green tea can contribute without a required companion ingredient.
Conflicts
No configured ingredient conflict was identified in the supplied findings.
Effective doses
Green tea meets the amount threshold used for inclusion; this is not a proven effective clinical dose.
Impact

Green Tea · 400 mg
Green tea supplies compounds with antioxidant activity, which explains its connection to this goal. Human dietary-tea associations and laboratory EGCG mechanisms do not establish that this concentrated extract preserves age-related function or extends life. Vitamin C contributes to normal collagen formation, but its small amount does not make a meaningful contribution in the saved findings.
