Ginkgo Biloba

Ginkgo leaf · a living fossil, studied hard and honestly

All articles checked for accuracy against the GB NHC Register and all sources have citations with verified links to their relevant studies.

Ginkgo biloba is a living fossil: a tree species that has survived for millions of years and whose leaf extract is one of the most studied botanicals. This article explains what ginkgo leaf is, how it’s used in WellsparQ formulas, what the research actually shows, and the safety points worth noting.

This piece covers the plant source and extract form of ginkgo, how WellsparQ includes it in formulations, the regulatory distinction between supplements and herbal medicines, a sober summary of trial findings (including large negative studies), and clear safety notes. It aims to be concise, accurate and compliant with regulatory limits on claims.

Ginkgo is a botanical with an unusually long backstory. Ginkgo biloba is often described as one of the oldest tree species still living — a "living fossil" whose lineage stretches back to before the age of the dinosaurs, and which survives today essentially unchanged. WellsparQ nods to exactly this on the label, calling ginkgo "leaf extract from one of the oldest tree species on record". It is also one of the most heavily researched plant extracts in the world. This page sets out the plant, the extract, what the trials have and have not shown, and the safety points that genuinely matter.

The plant and the part used

The ginkgo tree is the sole surviving member of its botanical order — every other relative is known only from the fossil record. The material used in supplements is the leaf (Latin Ginkgo folium), not the seed. WellsparQ uses the variants "Ginkgo Biloba" and "Ginkgo Leaf". It is a plant material, so ginkgo is suitable for vegans.

Leaf extracts are usually standardised to two families of constituents: flavonol glycosides (around 22–27%) and terpene lactones — the ginkgolides and bilobalide (around 5–7%). The most studied standardised preparation in the research literature is a specific extract known as EGb 761. When trials are discussed below, most used a standardised extract of this kind rather than crude powdered leaf — an important detail, because a defined extract and a raw leaf are not interchangeable.

How WellsparQ uses it

Ginkgo appears in two WellsparQ formulas as a supporting botanical, declared as an extract equivalent.

Source: WellsparQ Supplements Database. These are declared botanical amounts within multi-ingredient formulas, not isolated therapeutic doses of a standardised medicine.

Two regulatory identities

Like several well-known botanicals, ginkgo lives a double life in the rules, and the distinction governs what may be said.

As a botanical in a food supplement, ginkgo has no authorised health claim under retained EU Regulation 1924/2006 — its general-function claims have been on hold since around 2010, and none has been authorised ^⁵. WellsparQ therefore makes no benefit claim for ginkgo.

As a herbal medicine, ginkgo leaf is covered by a European Medicines Agency (HMPC) European Union herbal monograph ^¹. That monograph is instructive because it splits ginkgo's uses by strength of evidence:

• Certain ginkgo-leaf medicines are recognised on "well-established use" grounds for improvement of cognitive impairment and of quality of life in mild dementia, reflecting bibliographic clinical-trial data ^¹.
• Other ginkgo-leaf medicines rest on "traditional use" for minor circulation problems and related complaints — where, in the regulator's words, clinical-trial evidence is insufficient and recognition is based on long-standing use ^¹.

This is regulatory and traditional-use fact. It describes licensed medicines assessed under medicines law — not a permission for a WellsparQ supplement to make the same statements.

What the trials actually found — including the disappointments

Ginkgo is a good example of why honesty matters more than enthusiasm. Despite a large literature, the highest-quality trials in prevention have been negative, and it would be misleading to imply otherwise.

The landmark study is the Ginkgo Evaluation of Memory (GEM) trial, funded by the US National Institutes of Health — a large, randomised, placebo-controlled trial in older adults. It found that ginkgo extract (240 mg/day of a standardised preparation) did not reduce the incidence of dementia or Alzheimer's disease compared with placebo ^²³. A companion analysis from the same trial found ginkgo did not slow cognitive decline in older adults either ^⁴. The NCCIH summarises the position bluntly: across three large studies in older adults, ginkgo supplementation did not reduce the risk of dementia, and it has not been shown to prevent or slow it ^².

Where the picture is less settled, results are mixed: some trials of standardised extract in people who already have cognitive impairment or dementia have reported modest effects, which is part of why the EMA monograph recognises a well-established-use indication in mild dementia specifically ^¹². But "mixed, modest, in an already-affected group" is a very different statement from "prevents memory loss", and only the former is accurate.

None of this is a claim WellsparQ may make. It is reported as evidence — who ran the trial, what they gave, and what they found — with the negatives stated as plainly as any positive.

Safety — the point not to skip

This is the section to read twice. Ginkgo's most important practical issue is bleeding risk and drug interactions, not the leaf itself being toxic.

• Ginkgo may increase the risk of bleeding, particularly in people taking anticoagulant or antiplatelet medicines such as warfarin (and, by the same logic, drugs like aspirin or clopidogrel) ^². Anyone on blood-thinning medication should speak to a GP or pharmacist before using ginkgo.
• Because of bleeding risk, ginkgo is generally stopped before surgery.
• Ginkgo is considered best avoided in pregnancy; it might affect labour or bleeding around delivery, and little is known about safety while breastfeeding ^².
• Reported side effects are usually mild — headache, dizziness, digestive upset ^². (Note: ginkgo seeds, and raw or roasted, are a separate matter and can be toxic — but supplements use leaf extract, not seed.)

Where it fits your day

In BacoPanax and MacaVital, ginkgo is a supporting botanical with a remarkable heritage — the leaf of a tree that has outlasted almost everything. WellsparQ carries it for what it is, declares it plainly, reports the research faithfully including the parts that did not pan out, and flags the safety points that matter. Rooted in nature, backed by research — and honest about the limits of both.
