Analysis

The supplied ingredient data list 200 mg of green tea leaf extract despite a 100 mg figure in the title. That discrepancy should be resolved from the current package label.

No EGCG, catechin percentage, or caffeine amount is provided. Two tablets appear to make a full serving, and no absorption aid is listed.

It may suit users who want a basic unstandardized extract and can verify the dose. A clearly standardized one-tablet product would be easier to compare and use.

Who is it for
  • Adults seeking a basic green tea extract
  • Users willing to check the current package label
  • People comfortable with a two-tablet serving
Best for
  • Entry-level green tea supplementation
  • Short-term trial use
  • Users prioritizing low purchase cost

Pros

  • Simple single-extract formula
  • Supplied data list 200 mg green tea
  • Low purchase cost
  • No proprietary blend

Cons

  • Title and supplied dose differ
  • EGCG is not stated
  • Caffeine is not disclosed
  • Requires two tablets per serving

Warnings

  • Confirm the current label because the title and supplied ingredient amount do not match.
  • Unknown caffeine may cause sleep disruption or jitteriness.
  • Green tea extract may cause nausea when taken without food.

Nutrient quality

71 High impact

The ingredient identity is clear but no active-marker standardization is supplied. The amount may contribute, though effective catechin exposure cannot be verified.

.

Ingredient transparency

72 High impact

The total green-tea amount is visible without a hidden blend. Marker yields, caffeine, directions, and inactive ingredients are missing.

.

Customer satisfaction

70 High impact

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

.

Value for money

75 High impact

Low price and a simple formula support basic value. Missing potency data prevents judging effective serving value.

Green Tea · 200 mg

Green tea extract may support antioxidant and inflammatory balance, both relevant to healthy aging. The simple formula avoids unnecessary additions.

Missing EGCG yield, active standardization, and caffeine content prevent a reliable assessment of potency or stimulant exposure. A generic 200 mg extract also covers only a narrow longevity pathway.

A straightforward green tea extract is supplied without extra delivery technology. The label omits EGCG yield, active-marker standardization, and caffeine content. Those gaps prevent a reliable judgment of dose, stimulant exposure, or economic value.

EGCg Green Tea Extract

Protocol For Life Balance
<p>The supplied data does not show a lower recurring cost than the original, though it remains an eligible green-tea alternative.

Decaffeinated Mega Green Tea Extract

Life Extension
<p>It matches the original green-tea collection, but the supplied cost data does not establish a cheaper serving. Clear decaffeination and a measured EGCG amount make the active profile easy to understand. The 725 mg dose remains unusually high and may stress the liver, especially when taken fasting or used by someone with liver disease.</p>

NOW
<p>It pairs a lower recurring cost with the same green-tea collection, supporting a practical value case against the original. A modest EGCG amount pairs with a substantial pine bark extract for broad antioxidant support. Missing caffeine and marker percentages limit precision, though serving value remains fair.</p>
