Buy it. A gentle, water-extracted 500 mg green tea — a milder dose that's hard to overdo. Jarrow's water-extracted 500 mg green tea (50% polyphenols / ~30% catechins) from a long-respected brand is a lower, gentler catechin dose at a strong price per dose in a 100-count bottle.

Why It Scores 8.2 — And The Label Line Behind Each Number
EGCG standardization & dose
35% of scoreA 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.
- Extract
- 500 mg water-extracted green tea (50% polyphenols, ~30% catechins)
- EGCG
- 75 mg per capsule (15% of the 500 mg extract, label-stated) — about a third of the top picks
Purity & third-party testing
30% of scoreA 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.
Safety & caffeine clarity
20% of scoreThe 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.
- Caffeine
- ~40 mg per capsule (water-extracted; read the label)
Value (cost per active mg)

Marketing Claims Vs. Reality
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).
What Our Test Actually Found
Correction: the label states 75 mg EGCG per capsule, not an unstated fraction
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.
The mildness is the whole point
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 and a trusted brand carry the purity score
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.
The caffeine runs a little higher
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.
Lower EGCG is the reason it ranks #5
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.

Quick Answers
Why does 'water-extracted' matter?
Water extraction uses water rather than solvents like acetone to concentrate the green tea compounds. Some buyers prefer it as a gentler, cleaner process, and Jarrow's water-extracted 500 mg green tea reflects that positioning. It also tends to deliver a milder, lower-EGCG profile than aggressively-standardized 98% extracts — which, for the liver-safety-conscious, is a feature rather than a flaw.
How much EGCG does it actually deliver?
Less than the high-standardization picks, but it's a stated figure, not a guess. The label lists 15% [75 mg] EGCG per capsule (of the 500 mg extract) — versus roughly 200-285 mg in the high-standardization picks. If you want a soft entry point that's genuinely hard to overdo, that's the appeal; if you want maximum EGCG, one of the higher-standardization picks is the better tool.
How much caffeine is in it?
Around 40 mg per capsule — more than the lightly-caffeinated picks like Life Extension (~25 mg) or Zhou (~15 mg). That's roughly a cup of green tea's worth. Read the label and factor it into your daily caffeine; if you're sensitive or dosing in the afternoon, a lower-caffeine or decaf option is a better fit.
Is it a good budget choice?
Yes. A 100-count bottle from a long-respected brand at a strong price makes the cost per dose low, and the water-extracted, non-GMO, gluten-free profile is reassuring. It ranks #5 because the lower EGCG means a milder effect and it carries more caffeine than the lightly-caffeinated picks — but as a gentle, trustworthy, well-priced entry point, it's an easy, honest buy taken with food.
