NOW Foods Ginkgo Biloba 120 mg Review
8.9/10SAC Product Score™
NOW Foods Ginkgo Biloba 120 mg is the trust-and-value sweet spot of the list. You get the full 24% flavone glycosides / 6% terpene lactones spec and the trial-standard 120 mg dose in a single daily capsule, plus a real third-party Non-GMO Project Verification and NOW's unusually transparent in-house QC lab — all at about fifteen cents a serving. For a buyer who wants documented quality without paying a premium, this is the natural choice. It sits at #3 rather than higher for two narrow reasons: Doctor's Best (#1) delivers the identical spec and dose a few cents cheaper, and Nature's Way Ginkgold (#2) uses a named, clinically-referenced branded extract. NOW gives up nothing on standardisation, dose, or trust — it's simply edged on price-versus-spec and provenance. For many buyers, the Non-GMO Project seal makes it an equally defensible #1. Here's the full breakdown.

Extract standardisation30%9/10
The full 24% flavone glycosides / 6% terpene lactones spec as a clean single-herb extract — the clinical benchmark, clearly stated. Strong standardisation; a step below Doctor's Best/Ginkgold only because those state the 50:1 ratio or named branded material more prominently.
Dose vs the studied 120-240 mg range25%10/10
A full 120 mg 'Double Strength' dose in one daily capsule — the trial-standard dose, no two-capsule math. 'Double Strength' refers to dose convenience (vs older 60 mg caps), not a higher-concentration extract. Squarely in the studied 120-240 mg range.
Purity & third-party testing20%8/10
The strongest documented quality at this price tier: a real third-party Non-GMO Project Verification plus NOW's unusually transparent in-house QC lab, made without major allergens. Held below the top by the absence of a printed ginkgolic-acid limit (Life Extension's edge) and a true NSF/USP seal — which essentially no ginkgo carries.
Value per effective day15%9/10
Roughly $0.15 per 120 mg capsule in a 100-count bottle — strong value, only a few cents above the cheapest spec-matched pick. The small premium over Doctor's Best buys the Non-GMO Project seal and NOW's QC transparency, which many buyers will consider worth it.
Real-world response10%7.5/10
One veg capsule a day at the clinical dose, vegan and kosher, from a brand with a 30+ year reliability record — easy to take consistently. Loses ground only for generic single-herb positioning with no added co-factors, the same as most picks here.

Marketing claims vs. reality
Verified
“Non-GMO Project Verified.”
A genuine third-party Non-GMO Project verification, which is more than most ginkgo bottles carry — an outside check rather than an in-house claim.
Verified
“Double Strength 120 mg per capsule.”
A full 120 mg per capsule, 'double' the older 60 mg-per-cap products — the trial-standard dose in one capsule. 'Double Strength' refers to dose, not a stronger extract concentration; the spec is the standard 24%/6%.
Partial
“Supports brain function and circulation.”
Real but modest. Standardised ginkgo supported cognition/circulation in impaired populations (Le Bars 1997; Herrschaft 2012; Pittler & Ernst 2000); it does not prevent decline in healthy people (GEM, DeKosky 2008). Honest as a support claim, not a strong-nootropic or prevention claim.
What our test actually found
01The Non-GMO Project seal is a real edge at this price
Most commodity ginkgo offers only in-house quality claims. NOW adds a genuine third-party Non-GMO Project Verification on top of its own transparent QC lab — an outside check that few competitors at this price carry. It's not the most safety-critical marker for ginkgo (ginkgolic acid matters more), but it's a real, externally-administered trust signal, and it's the main reason the small premium over Doctor's Best is easy to justify.
02NOW's QC transparency is the brand's underrated strength
NOW publishes more about its in-house testing than almost any commodity supplement brand, backed by a 30+ year track record. In-house testing isn't the same as an independent certifier, but NOW's openness about its process — combined with the Non-GMO seal — makes this one of the better-documented value ginkgos. For a buyer who wants to trust the bottle without paying premium-brand prices, that transparency is worth real weight.
03'Double Strength' is dose convenience, not a stronger extract
It's worth being clear: 'Double Strength' means 120 mg per capsule (vs older 60 mg-per-cap ginkgo), so you hit the clinical dose in one capsule instead of two. The extract concentration is the standard 24%/6% — it is NOT a higher-potency material. That's still a genuine plus: one capsule a day at the trial-standard 120 mg, which is simpler to sustain than the two-capsule routine the 60 mg picks (Jarrow #7, Solgar #9) require.
04It's #3 by inches, not by quality
NOW gives up nothing meaningful to the top two. It loses to Doctor's Best (#1) only on price — same spec, same dose, a few cents more — and to Ginkgold (#2) only on named extract provenance. On standardisation, dose, certification, and brand trust it's right there with them. Many buyers should treat the Non-GMO Project seal as worth the tiny premium and consider this their #1; the ranking gap is genuinely small.
05Same honest ceiling — a modest symptomatic support
Like every ginkgo here, NOW's is a modest symptomatic helper, not a prevention drug. The replicated benefit is in memory and circulation for people with measurable impairment (Le Bars 1997; Herrschaft 2012; Pittler & Ernst 2000), and the GEM Study (DeKosky 2008) showed 240 mg/day didn't prevent decline over six years. Buy it as a well-documented, low-cost standardised extract to run patiently for 6-8 weeks, and keep the expectation grounded.
Pros & cons, no sugar-coating
Pros
- Real third-party Non-GMO Project Verification — more than most ginkgo carries
- Full 24%/6% spec at a 120 mg 'Double Strength' dose in one daily capsule
- NOW's unusually transparent in-house QC and 30+ year track record
- Vegan, kosher, made without major allergens
- Strong value at ~$0.15 per serving — just above the cheapest spec-matched pick
Cons
- A few cents more per serving than Doctor's Best (#1) for the identical spec
- No named, clinically-referenced branded extract (that's Ginkgold, #2)
- No printed ginkgolic-acid limit (Life Extension #4 states <1 ppm)
- Modest, symptomatic effect — like all ginkgo, not a prevention drug
The trust-and-value pick — buy it for the verified seal at a fair price.
NOW Foods Ginkgo Biloba 120 mg is the bottle for buyers who want documented quality without a premium. It delivers the full 24%/6% spec and the trial-standard 120 mg dose in one daily capsule, adds a genuine third-party Non-GMO Project Verification and NOW's transparent in-house QC, and prices it at about fifteen cents a serving. That combination of an external trust signal and value is hard to beat in this category. It ranks third by inches, not by quality. Doctor's Best (#1) gives the identical spec and dose for a few cents less, and Nature's Way Ginkgold (#2) uses a named branded extract — but NOW concedes nothing on standardisation, dose, or trust, and for many buyers the Non-GMO Project seal justifies the tiny premium, making this an equally valid #1. As with all ginkgo, keep the expectation honest: it's a modest symptomatic support for memory and circulation (Le Bars 1997; Herrschaft 2012; Pittler & Ernst 2000), not a prevention drug — the GEM Study (DeKosky 2008) settled that. Take one capsule daily for 6-8 weeks and judge it on its merits.
