Mega Green Tea Extract (Decaffeinated)
A genuinely single-ingredient green tea extract, dual standardized to both total polyphenols and EGCG specifically, with the EGCG dose disclosed in exact milligrams rather than left to a percentage figure alone.

100 Capsules
1 capsule daily
CURATEDFIT SUMMARY
Passes because this is a single-ingredient formula, decaffeinated green tea leaf extract, standardized against two markers rather than one, total polyphenols and EGCG specifically, with the EGCG content disclosed as an exact milligram figure (326.25 mg) rather than only a percentage. There is no proprietary blend, no synthetic actives, and no undisclosed ratio to untangle. Worth knowing before use: this is the decaffeinated version, and some of the research behind green tea extract's effect on fat oxidation used caffeinated extracts, where caffeine and EGCG are thought to work synergistically. That doesn't disqualify this product, but it's a meaningful distinction from a caffeinated green tea extract and worth understanding before choosing between the two.
WHAT IT IS
A vegetarian capsule providing 725 mg of decaffeinated green tea (Camellia sinensis) leaf extract, standardized to 98% total polyphenols and specifically to 45% EGCG (epigallocatechin gallate), the polyphenol most studied for its role in fat oxidation and metabolic function. Each capsule still contains a small residual amount of caffeine (up to 3.6 mg), effectively negligible, consistent with the "decaffeinated" labeling rather than being a stimulant-free claim in the strictest sense.
WHO IT IS FOR
Someone who wants a clean, single-ingredient EGCG source at a disclosed, research-relevant dose, and who specifically wants to avoid the caffeine load that comes with a standard caffeinated green tea extract or fat-oxidation stack.
INGREDIENT BREAKDOWN
Green Tea Decaffeinated Leaf Extract (std. to 98% polyphenols, 45% EGCG / 326.25 mg)
725 mg
A biologically sourced botanical extract. The dual standardization, both total polyphenols and the specific EGCG marker, is a stronger transparency signal than a single polyphenol percentage alone, since EGCG is the compound most directly relevant to the metabolic and fat oxidation research behind this ingredient. The label's own caution against exceeding 800 mg of EGCG daily is a useful, honest reference point, this product's single-capsule dose sits well within that ceiling.

TRANSPARENCY NOTE
Human research on green tea catechins and fat oxidation has generally used EGCG doses in a range that overlaps with, and in some studies exceeds, the 326.25 mg provided here. This dose is not a token or fairy-dusted amount, it sits at a defensible, research-relevant level. The open question isn't dose, it's format. Some of the more frequently cited fat-oxidation studies used caffeinated green tea extract, where caffeine's own thermogenic effect appears to work alongside EGCG rather than EGCG acting entirely alone. This product's decaffeinated format means that specific synergy isn't present, which doesn't invalidate the EGCG dose but is worth being upfront about rather than implying identical effects to the caffeinated research.
FREQUENTLY ASKED QUESTIONS
Where is this manufactured?
Not confirmed on the page reviewed.
Why decaffeinated instead of regular green tea extract?
For anyone managing total caffeine intake, sensitive to stimulants, or already using a caffeinated product elsewhere in a stack, and who still wants the EGCG-specific research profile without added caffeine.
Does removing the caffeine reduce the fat oxidation effect?
Some of the human research behind green tea extract and fat oxidation used caffeinated extracts, where caffeine and EGCG are thought to have a synergistic effect. This decaffeinated version still provides a research-relevant EGCG dose, but that specific synergy isn't part of the picture here.
Is 45% EGCG a meaningful standardization, or just a marketing number?
It's meaningful because it's paired with an exact milligram figure (326.25 mg), not left as a percentage alone. That lets the actual EGCG dose be checked against research thresholds directly, rather than requiring assumptions about extract potency.
Has this been tested for heavy metals or contaminants?
Not confirmed via any of the six specific certifications this review checks.
