Solgar Ginkgo Biloba Leaf Extract is the heritage-brand, lower-step option. The Standardized Full Potency (SFP) extract is a clean, kosher, vegan, single-herb formula from a long-respected premium name, in a large 180-count bottle, at 60 mg per capsule. For a buyer who specifically wants the Solgar name and a gentle 60 mg titration step, it's a recognisable, well-made choice. It ranks last on the two axes that matter most for everyday value: dosing efficiency and price. At 60 mg per capsule you need two capsules to reach the 120 mg clinical dose, which — combined with the premium pricing — makes it the most expensive pick per effective milligram on the list. The extract itself is a legitimate standardised material; it's the 60 mg format and the heritage-brand premium that hold it at #9. Here's the full breakdown.

Read the complete Ginkgo Biloba guide →A legitimate Standardized Full Potency extract guaranteeing 24% flavone glycosides, from a heritage premium brand — a credible, named standardisation approach. Held a step below the top only because the listing foregrounds the 24% figure and is less prominent on the matching 6% terpene-lactone half than the picks that print the complete 24%/6% spec.
60 mg per capsule means the trial-standard 120 mg dose requires two capsules. A gentle 60 mg titration step is available, but reaching the clinical dose isn't a one-capsule action and the dose math falls to the buyer. Marked down for the two-capsule requirement, the same as Jarrow (#7).
Kosher, vegan, non-GMO, gluten- and dairy-free, in a clean single-herb formula from a long-established premium brand — one of the strongest formulation-purity stories on the list. A notch below the top only because, like most ginkgo, it doesn't print an explicit ginkgolic-acid limit (Life Extension's edge) or carry an NSF/USP seal.
About $0.30 per 120 mg serving (two capsules) — the most expensive pick per effective milligram on the list, driven by the premium price and the 60 mg-per-capsule format. The weakest axis by a clear margin, and the main reason it ranks last despite a clean formula and a respected name.
A recognisable heritage brand and a large 180-count bottle are real-world positives, but the two-capsule clinical dose adds the same friction as Jarrow, and the premium price-to-convenience ratio is the worst here. Net: pleasant to own for brand loyalists, fiddlier and pricier than the one-capsule picks.
“Standardized Full Potency (SFP) extract guaranteeing 24% flavone glycosides.”
Accurate as stated — a legitimate standardised extract guaranteeing 24% flavone glycosides. Scored partial because the listing is less prominent on the matching 6% terpene-lactone half of the full EGb 761 spec, which the higher-ranked picks print explicitly.
“Kosher, vegan, non-GMO, gluten- and dairy-free.”
The listing states all of these, consistent with Solgar's clean-label premium formulation. A genuine strength of the product and reliably accurate.
“60 mg per capsule from a trusted premium brand.”
Each capsule is 60 mg, from a long-established premium supplement brand. Accurate — and the reason buyers need two capsules (and must do the math) to reach the 120 mg clinical dose.
“Supports memory and mental alertness.”
Real but modest, like all ginkgo, and only at the clinical 120 mg dose (two capsules). Standardised ginkgo helped cognition/circulation in impaired populations (Le Bars 1997; Herrschaft 2012; Pittler & Ernst 2000); it does not prevent decline in healthy people (GEM, DeKosky 2008).
The SFP extract is a genuine standardised ginkgo, and the formulation is among the cleanest on the list: kosher, vegan, non-GMO, gluten- and dairy-free, single-herb, from a respected heritage brand. The #9 ranking isn't a quality verdict — it's a value-and-dosing one. If you judged Solgar on its formula and brand alone it would rank higher; the 60 mg-per-capsule format and the premium price are what pull it down.
Here's the core problem: at 60 mg per capsule you need two capsules for the 120 mg clinical dose, and at Solgar's premium price that works out to about thirty cents per effective serving — the most expensive on the list per milligram of ginkgo delivered. The same clinical dose is available for a fraction of that from the one-capsule value picks (Doctor's Best #1 at ~11 cents). The premium buys the Solgar name and clean formulation, not a stronger effect.
Like Jarrow (#7), Solgar is a 60 mg-per-capsule product, so the trial-standard 120 mg dose requires two capsules, and a careless buyer could under-dose at one. The flexibility to run a gentle 60 mg step is a genuine plus for titrators, but it shifts the dose math onto you. If you want the clinical dose in a single capsule, this isn't the format — the 120 mg-per-cap picks are simpler.
Within the 60 mg-per-capsule niche, Jarrow (#7) is the more efficient choice: same format, same two-capsule requirement, but a lower bottle price and therefore a lower cost per effective milligram. Solgar's edge over Jarrow is purely the heritage premium brand, the kosher/vegan clean-label story, and the larger 180-count bottle. If those specifics matter to you, fine; if not, Jarrow is the better-value version of the same idea.
Once you're dosing correctly at 120 mg (two capsules), the expectation is the same as any ginkgo: 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. Take the clinical dose daily for 6-8 weeks, and judge it honestly.
Solgar Ginkgo Biloba Leaf Extract is the ginkgo for a Solgar loyalist who wants a clean, recognisable, premium formula and a gentle 60 mg titration step. The Standardized Full Potency extract is legitimate, the formulation is genuinely clean — kosher, vegan, non-GMO, gluten- and dairy-free — and the 180-count bottle lasts a while. If the heritage brand and the clean-label story matter to you, it's a well-made, dependable choice. What it isn't is efficient or good value, which is why it ranks last. At 60 mg per capsule you need two capsules for the 120 mg clinical dose, and at Solgar's premium price that makes it the most expensive pick per effective milligram on the list — the same clinical dose costs a fraction as much from the one-capsule value picks (Doctor's Best #1), and even the other 60 mg pick (Jarrow #7) does the job for less. The premium buys the brand and the formulation, not a stronger effect. 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. Dose it deliberately at 120 mg/day (two capsules) for 6-8 weeks, and judge it then.
