SAC StudioA gentle, water-extracted 500 mg green tea — a milder dose that's hard to overdo.
Jarrow's Green Tea is the gentle, water-extracted option and a genuinely sensible budget buy. It's a 500 mg water-extracted green tea at 50% polyphenols / ~30% catechins, which means a lower, milder EGCG dose than the high-standardization capsules — and for the liver-safety conscious, a dose that's hard to overdo is a feature, not a flaw. The brand's QC and water-extraction are reassuring, and the price per dose is strong.
It ranks #5 because the lower EGCG means a more modest effect, and it carries a bit more caffeine (~40 mg) than the lightly-caffeinated picks. If you want a gentle, trustworthy, well-priced extract and aren't chasing maximum EGCG, it's an easy, honest choice — taken with food, and, as always, a modest fat-loss adjunct on top of a deficit, not a fat burner.
A 500 mg water-extracted green tea at 50% polyphenols / 30% catechins / 15% [75 mg] EGCG per capsule — a label-stated dose, but about a third of the 45-50% EGCG extracts, so a gentle, milder dose by design. The lowest-potency profile in the top half of the list, which is deliberate but caps this axis.
A real strength: water-extracted (not solvent/acetone), with non-GMO and gluten-free label claims (self-declared — the label carries no third-party seal, and no cGMP statement appears on it). The gentle extraction and Jarrow's long-established brand pedigree score well on purity.
The milder, hard-to-overdo dose is inherently safety-friendly. It loses a little here only because it carries ~40 mg of caffeine — more than the lightly-caffeinated picks — and that caffeine should be read off the label and factored into your daily total.
Strong: a 100-count bottle from a respected brand at a low price per dose. Good value for a gentle, trustworthy extract, though the lower EGCG fraction means you're paying for a milder dose per capsule.
“500 mg water-extracted green tea, standardized to 50% polyphenols / ~30% catechins.”
The listing states a 500 mg water-extracted green tea standardized to 50% polyphenols with ~30% catechins. The water-extraction and standardization are disclosed and hold up; the EGCG fraction is correspondingly lower than a 45% EGCG extract.
“Water-extracted (not solvent-extracted).”
The listing specifies water extraction, consistent with Jarrow's positioning for this SKU. Accurate and a genuine differentiator for buyers who prefer a gentler process.
“Non-GMO, gluten-free.”
The label carries non-GMO and gluten-free claims (self-declared — no third-party seal such as NSF, USP or Non-GMO Project appears on it). No cGMP statement or certification mark is printed on the label, so a cGMP claim isn't verifiable from the label alone.
“Cardiovascular and immune health support.”
Directionally plausible for green tea polyphenols but not a proven product-specific outcome. Reasonable as a category antioxidant claim; the fat-loss effect specifically is modest (Hursel 2009).
An earlier version of this review said the water-extracted profile meant no precise EGCG mg was stated, and separately described the EGCG content as roughly 15% of the catechins. The Supplement Facts panel reads: Green Tea Leaf Extract 500 mg — 50% [250 mg] Polyphenols, 30% [150 mg] Catechins, 15% [75 mg] EGCG (Epigallocatechin Gallate). The 15% is of the 500 mg extract, not of the catechin fraction, so the correct figure is 75 mg EGCG per capsule, a figure the label states plainly. We re-read the label on Sep 3, 2026 and corrected the text throughout; the EGCG standardization score is unchanged at 7.8/10 — 75 mg per capsule still supports ranking it below the 45-50% EGCG picks.
Jarrow's water-extracted 500 mg green tea delivers a lower, gentler catechin dose than the aggressively-standardized 98% extracts. For a cautious or entry-level buyer — and especially for the liver-safety-conscious — a dose that's genuinely hard to overdo is a feature, not a shortfall. It's the pick when you want a soft, low-risk way to get some catechins.
Water extraction (rather than solvent/acetone) plus Jarrow's decades-long reputation and non-GMO and gluten-free label claims make this one of the stronger picks on purity, even though those claims are self-declared rather than backed by a third-party seal on this label. The gentle process and established pedigree are what lift it above flashier but less-trusted extracts on that axis.
At ~40 mg of caffeine per capsule, Jarrow carries more than the lightly-caffeinated picks like Life Extension (~25 mg) or Zhou (~15 mg) — roughly a cup of green tea's worth. Read it off the label and count it toward your daily total; if you're caffeine-sensitive or dosing late, a lower-caffeine or decaf option is a better fit.
The honest trade-off: because the EGCG fraction is lower, the catechin effect is more modest than the high-standardization picks. That's fine if you want a gentle entry point, but if you specifically want maximum EGCG per capsule, one of the 45-50% EGCG extracts above it is the better tool. Take it with food and it's an easy, trustworthy, well-priced choice.

The overall winner — ~200 mg EGCG, very low caffeine, top-tier QC, 180-count. Choose it if you want a stronger stated EGCG dose with lower caffeine.
See it on the list →The caffeine-control pick — ~285 mg EGCG with caffeine stated and a decaf option. Choose it if you want a stronger dose with precise caffeine control.
See it on the list →A cleanly-standardized ~225 mg EGCG dose from a full-disclosure-label brand. Choose it if you want a stronger, fully-standardized dose with transparent labeling.
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. A gentle, lower-EGCG extract like Jarrow's is a mild version of this already-modest effect.
Systematic review: liver-related adverse effects were associated with high-dose extract taken fasted. Jarrow's gentle, hard-to-overdo dose sits at the low-risk end of this signal.
Systematic review of RCTs: liver-enzyme elevations clustered at higher EGCG doses — reinforcing that Jarrow's low-EGCG, water-extracted profile is among the lowest-risk in the lineup.
