SAC StudioA moderate, clearly-labelled EGCG dose (~225 mg per capsule) with caffeine stated on the back panel.
Nature's Wellness delivers a moderate, honestly-labelled EGCG dose: 500 mg of 98% green tea extract per capsule, standardized to 45% minimum EGCG (about 225 mg) and 75% minimum polyphenol catechins, third-party lab tested in a GMP-compliant facility. The back label also states its caffeine plainly — 15 mg per capsule — putting it on par with Zhou's stated-caffeine disclosure rather than leaving you guessing.
The honest trade-offs are why it lands in 'consider' territory rather than 'buy'. At ~225 mg per capsule it isn't the highest-EGCG pick in the lineup — Life Extension (~285 mg) and Zhou (~250 mg) both provide more — so the cost per active mg is roughly double what an earlier version of this review assumed, since the actual EGCG per capsule is half of what was claimed. As a smaller brand, its testing transparency, while solid, also doesn't match the category leaders. It's a fine, clearly-labelled option at 1-2 capsules a day with meals; just don't expect it to out-dose the picks above it.
500 mg of 98% extract per capsule, standardized to 45% minimum EGCG (~225 mg) and 75% minimum polyphenol catechins — a moderate, clearly-disclosed dose, not the highest in the lineup. Life Extension (~285 mg) and Zhou (~250 mg) both provide more EGCG per capsule; this sits closer to NOW's ~200 mg. The minimum-percentage labeling is an honest, conservative disclosure, which keeps the score respectable even though it isn't the top dose here.
Third-party lab tested in a GMP-compliant facility — better disclosure than several rivals. It sits below the category leaders here because, as a smaller brand, its testing transparency and documentation don't reach the tier of NOW or Life Extension.
Both pieces of this axis are better than an earlier version of this review credited: the EGCG dose is moderate (~225 mg per capsule, not a high single-cap bolus), and the caffeine is precisely stated on the back label — 15 mg per serving, capped at 5% of the extract — the same stated-low-caffeine disclosure this review credits Zhou for. The label's own suggested use is 1 to 2 capsules a day with meals, with no unusual dosing caution required.
Moderate rather than standout: at ~225 mg of EGCG per capsule — half the amount an earlier version of this review assumed — the cost per active mg is roughly double what was previously stated. It's still a reasonably priced, 120-capsule bottle, but it no longer beats the premium extracts on EGCG per dollar.
“500 mg EGCG per capsule (brand's own gallery-tile marketing claim).”
The Supplement Facts panel shows 500 mg of 98% green tea extract per capsule, standardized to 45% minimum EGCG — about 225 mg of EGCG, not 500 mg. The brand's own marketing tile overstates its panel by roughly 2x; we're flagging the manufacturer's claim as false rather than repeating it.
“Third-party lab tested.”
The listing states third-party lab testing in a GMP-compliant facility, which is more than several rivals offer, but it names no specific certifier and publishes no batch COA on the listing. We mark it partial — reassuring but not a document you can read.
“Natural caffeine / antioxidant support.”
The caffeine is naturally occurring and precisely disclosed on the back label — 15 mg per capsule, capped at 5% of the extract; the antioxidant framing is directionally accurate for catechins but not a proven product-specific outcome.
“Healthy weight support, metabolism, energy, heart health.”
Directionally supported by the modest catechin evidence (Hursel 2009) but overstated relative to the small, adjunctive effect. Reasonable as a category claim; not dramatic or product-specific.
An earlier version of this review said Nature's Wellness delivers a 1000 mg extract with ~450 mg of EGCG in a single capsule and stated its caffeine was 'naturally occurring, read the label' with no number given. The Supplement Facts panel reads: Serving Size 1 Capsule; Green Tea 98% Extract (dried leaves) 500 mg; Epigallocatechin-3-gallate 45% Minimum (about 225 mg EGCG); Naturally-Occurring Caffeine 5% Maximum, and the back label states 15 mg of caffeine per serving. The 1000 mg / ~450 mg figure only applies at the label's 2-capsule daily maximum, not per capsule. We re-read the label on Sep 3, 2026 and revised the EGCG-per-capsule, caffeine, cost-per-mg, and badge language throughout, and rescored the EGCG standardization & dose (7.4, was 8.8), Safety & caffeine clarity (8.8, was 8.0), and Value (7.0, was 8.8) axes — overallScore moved from 8.5 to 7.9 and the verdict from buy to consider.
At 98% extract and 45% minimum EGCG, Nature's Wellness delivers about 225 mg of EGCG per capsule plus 75% minimum polyphenol catechins — a moderate dose, not the highest in the lineup. Life Extension (~285 mg) and Zhou (~250 mg) both provide more EGCG per capsule; this sits closer to NOW's ~200 mg. The minimum-percentage labeling is a conservative, honest way to disclose it.
The back label states 15 mg of caffeine per capsule, capped at 5% of the extract — the same stated-low-caffeine disclosure this review credits Zhou for. Because the EGCG dose is moderate rather than a high bolus, the label's own suggested use (1 to 2 capsules a day with meals) is all the dosing guidance you need.
The listing's third-party lab testing in a GMP facility is genuinely better disclosure than many rivals offer. But Nature's Wellness is a smaller brand, so its testing transparency doesn't reach NOW or Life Extension's tier — no certifier is named and no batch COA is published. That's the honest reason it ranks below them on purity — the disclosure is good, not best-in-class.
At ~225 mg of EGCG per capsule — half of what an earlier version of this review assumed — the cost per active mg is roughly double what was previously stated. It's still a reasonably priced, 120-capsule bottle, but it no longer beats the premium extracts on EGCG per dollar; for a moderate dose with deeper QC documentation, NOW (#1) is the better fit.
Nature's Wellness is a fair fit for a buyer who wants a moderate, clearly-disclosed EGCG dose rather than the maximum number on the list. At 98% extract and 45% minimum EGCG, it delivers about 225 mg of EGCG per capsule, it's third-party lab tested, and both the EGCG and caffeine content are spelled out on the label. The honest trade-offs are why it lands in 'consider' territory rather than 'buy'. It isn't the highest-EGCG pick here — Life Extension (~285 mg) and Zhou (~250 mg) both provide more — so the cost per active mg is decent rather than exceptional, and as a smaller brand its testing transparency, while solid, doesn't match the category leaders. Take it with meals per the label's own 1-2 capsule daily guidance, and it's a fine, straightforwardly-labelled option — just not the max-potency one.

The overall winner — a moderate ~200 mg EGCG dose, very low caffeine, top-tier QC, 180-count (per NOW's own label). Choose it if you want the safest, best-value default.
See it on the list →The caffeine-control pick — ~285 mg EGCG with caffeine stated and a decaf option, premium QC (per Life Extension's own label). Choose it if you want more EGCG per capsule plus caffeine clarity.
See it on the list →A clean, transparent ~250 mg EGCG mid-dose with caffeine stated (~15 mg, per Zhou's own label). Choose it if you want slightly more EGCG at a similar caffeine-disclosure standard.
See it on the list →Meta-analysis of 11 studies: green tea catechins were associated with a modest ~1.3 kg mean weight change, clearest with caffeine. At ~225 mg of EGCG per capsule this is a moderate, category-typical dose rather than an outsized one, but the effect size itself stays modest regardless of dose.
Systematic review: liver-related adverse effects were associated with high-dose extract taken fasted. At ~225 mg of EGCG per capsule this product sits well under the doses of concern, but the general rule still applies — take green tea extract with food.
Systematic review of RCTs: liver-enzyme elevations clustered at higher EGCG doses. At ~225 mg per capsule, this pick sits in the moderate range rather than the higher end this dose-dependent signal warns about.
