Analysis

824 mg of green-tea leaf extract of green tea material provides a direct source of catechins that may support antioxidant defenses and normal metabolic signaling. The total leaf-extract amount is clear, but no catechin, EGCG, or caffeine data are supplied.

Caffeine content is not stated, making stimulant exposure difficult to judge. Active potency and stimulant exposure cannot be verified prevents a fully confident comparison with better-characterized extracts.

The liquid format keeps the product focused and easy to fit into a routine. The alcohol-free liquid may suit tincture users, but flexibility does not compensate for missing active characterization.

Who is it for
  • Adults seeking concentrated green tea catechins
  • People comfortable with potentially caffeinated green tea
Best for
  • Green tea catechin intake
  • Antioxidant support
  • Metabolic-support routines

Pros

  • Provides 824 mg of green-tea leaf extract
  • Identifies EGCG or catechin markers
  • Offers reasonable bottle value
  • Simple liquid format

Cons

  • active potency and stimulant exposure cannot be verified
  • Caffeine amount is not disclosed
  • No absorption-support ingredients
  • Narrow single-botanical scope

Warnings

  • Concentrated green tea extract has occasionally been linked with liver injury, particularly when taken fasting; stop use for dark urine, jaundice, or persistent upper-abdominal pain.
  • Green tea catechins can reduce non-heme iron absorption, so people using oral iron should separate the servings.
  • Caffeine content is not disclosed, so caffeine-sensitive users cannot predict effects on sleep, heart rate, or anxiety.

Nutrient quality

60 Moderate impact

Green tea species is identified, but extract markers and standardization are absent. The concentrated liquid remains difficult to judge because active strength and stimulant exposure are unknown.

Ingredient transparency

65 High impact

The total extract amount is clear, while EGCG, polyphenols, and caffeine are missing. No proprietary blend hides the listed active doses.

Customer satisfaction

62 Moderate impact

The supplied average is very strong, with small response volume. Complaint patterns and purpose-related experiences are not supplied.

Value for money

51 Moderate impact

The asking price is difficult to justify for the disclosed formula. Serving value is weak relative to the green tea support provided.

Green Tea · 824 mg

Green tea has relevant antioxidant and inflammatory-pathway activity, but the active catechin and EGCG amounts are not disclosed. The total extract weight therefore does not establish a meaningful anti-inflammatory dose.

Caffeine content, standardization, and absorption support are also unclear. The focused single-botanical design is coherent, yet underdisclosure limits confidence in its practical effect.

Green Tea · 824 mg

Green tea is directly relevant to fat oxidation and thermogenesis when EGCG and caffeine exposure are known. Here, the label states only total leaf extract, so neither active catechin potency nor stimulant content can be verified.

The alcohol-free liquid is simple and free from unrelated ingredients. Missing standardization, caffeine disclosure, and a defined EGCG amount prevent a credible effective-dose assessment.

F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The green tea extract does not disclose an active-marker percentage, while no catechin absorption technology or stabilizing cofactor is listed. The label does not disclose a specific EGCG amount, and caffeine content and decaffeination status are not disclosed. The liquid extract offers no verifiable EGCG yield or stimulant disclosure; value per active EGCG amount cannot be verified because EGCG is not disclosed.
