What Are Nutricost Ginkgo Biloba Capsules?
Nutricost Ginkgo Biloba capsules deliver 120 mg of standardized Ginkgo Biloba leaf extract in a 50:1 concentrate per vegetarian capsule. Ginkgo Biloba is one of the oldest living plant species on earth — a "living fossil" traceable back more than 200 million years — and its medicinal use was first recorded as far back as 2800 BC in Chinese writings.
The standardized extract in these capsules provides optimal levels of naturally occurring flavonglycosides and terpene lactones, two compound classes central to Ginkgo Biloba's biological activity. Each batch is manufactured under strict European quality standards, which are comparable to over-the-counter drug standards in the United States, helping ensure maximum quality and potency.
Nutricost Ginkgo Biloba capsules are formulated around three primary areas of support: memory, circulation, and focus & concentration. The product is gluten free, dairy free, soy free, and grain free, making it accessible to individuals following a wide range of dietary protocols.
The Science Behind Ginkgo Biloba
The pharmacological activity of Ginkgo Biloba leaf extract stems from two principal compound classes: flavonol glycosides (standardized to approximately 24%) and terpene trilactones (standardized to approximately 6%), which include the ginkgolides and bilobalide. Together, these compounds drive a range of mechanisms that support brain health, vascular function, and antioxidant defense.
Antioxidant Protection
Ginkgo Biloba's flavonoids are potent free-radical scavengers. Research has established antioxidant activity as one possible mechanism for numerous pharmacological effects of the plant, including protection of neuronal and cardiovascular cells from reactive oxygen species (ROS)-mediated damage. The extract serves as a very powerful antioxidant, especially important for the brain, retina, and cardiovascular system.
Circulation and Vascular Support
Ginkgolide B is the most potent known naturally occurring inhibitor of platelet-activating factor (PAF), a key mediator of the extract's anti-aggregatory and anti-inflammatory effects. Research suggests that Ginkgo Biloba improves perfusion in different vascular beds without significantly affecting blood pressure and heart rate, supporting healthy hemodynamics and organ perfusion.
Neurotransmitter Modulation
Studies suggest that chronic treatment with standardized Ginkgo Biloba extract increases dopaminergic transmission in the prefrontal cortex, an area of the brain intimately involved in attention, working memory, and executive function. The increase in dopamine levels is mostly attributed to the flavonol glycoside and ginkgolide fractions of the extract.
Neuroprotection
Ingredients of ginkgo leaves have demonstrated appreciable blood-brain barrier (BBB)-crossing efficacy. Research indicates these compounds have numerous pharmacological effects in the central nervous system, from specific action on neurotransmitter receptors to general mechanisms of neuroprotection, and may improve neural plasticity.

Who Are Nutricost Ginkgo Biloba Capsules For?
Nutricost Ginkgo Biloba capsules are designed for adults seeking targeted support for memory, circulation, and focus & concentration. Because the product is gluten free, dairy free, soy free, and grain free, it accommodates a wide range of dietary needs.
Research suggests Ginkgo Biloba may particularly benefit individuals interested in supporting cognitive function as they age. An overview of ten systematic reviews found clear evidence supporting efficacy in mild cognitive impairment, with dose-dependent effects — though results in cognitively healthy adults are less conclusive.
Adults concerned with healthy circulation may also find these capsules relevant. Studies suggest that Ginkgo Biloba extract improves blood flow across multiple vascular beds, including cerebral, coronary, cutaneous, and peripheral circulation.
Those looking for potent antioxidant support — especially for the brain, retina, and cardiovascular system — may also consider this supplement as part of their wellness routine. Nutricost Ginkgo Biloba capsules come in vegetarian capsules, making them suitable for individuals following a vegetarian lifestyle.
Important note: Ginkgo may be unsafe for use during pregnancy, as it might cause early labor or extra bleeding during delivery. Little is known about its safety while breastfeeding. Individuals taking anticoagulant or antiplatelet drugs such as warfarin, clopidogrel, or aspirin should consult a healthcare professional before use, as Ginkgo Biloba may increase bleeding risk.
How to Take Nutricost Ginkgo Biloba Capsules
Take one (1) vegetarian capsule, two (2) times daily with meals.
Each capsule contains 120 mg of standardized Ginkgo Biloba leaf extract in a 50:1 concentrate, providing optimal levels of naturally occurring flavonglycosides and terpene lactones. The bottle contains 50 capsules.
The standardization of this extract under strict European guidelines helps ensure that every capsule delivers consistent potency. European Pharmacopoeia standards specify that the extract be adjusted to 22.0%–27.0% ginkgo flavonoids and 5.4%–6.6% terpene lactones, with ginkgolic acids limited to less than 5 parts per million to minimize the risk of adverse effects associated with those compounds.

Frequently asked questions
What is Ginkgo Biloba standardized extract, and why does standardization matter?
Standardized Ginkgo Biloba extract is produced by extracting dried leaves and adjusting the final product to contain specific concentrations of active compounds — typically around 24% flavonol glycosides and 6% terpene trilactones. Because of the wide variation of ginkgo products on the market, standardization ensures consistent quality and potency. Even two extracts meeting the same pharmacopoeia guideline can vary significantly; for example, a range of 22%–27% flavone glycosides means one extract could contain almost 23% more of that compound class than another. Nutricost Ginkgo Biloba capsules are standardized under strict European quality standards.
What does research say about Ginkgo Biloba and memory?
Research on Ginkgo Biloba and memory is extensive but mixed. Large prevention trials like the GEM study (3,069 participants, median 6.1 years of follow-up) found that 120 mg twice daily was not effective in preventing dementia or slowing cognitive decline in healthy older adults. However, evidence in people with existing mild cognitive impairment or dementia is more positive: a 2020 meta-analysis of 7 RCTs found some improvement in cognitive function with EGb 761, and an overview of ten systematic reviews concluded that improvement was dose-dependent and convincingly demonstrated at 240 mg/day. More research is needed to confirm optimal dosages and effectiveness.
Are Nutricost Ginkgo Biloba capsules safe, and are there any side effects?
In general, Ginkgo Biloba is considered safe and well-tolerated. Systematic review data shows that overall adverse events and serious adverse events occurred at the same level as placebo. Common mild side effects may include gastrointestinal upset, headaches, and dizziness. However, Ginkgo Biloba may increase bleeding risk in people taking anticoagulant or antiplatelet medications such as warfarin, clopidogrel, or aspirin. It may also be unsafe during pregnancy. Individuals on medications should consult a healthcare professional before use.
How does Ginkgo Biloba support circulation?
Research suggests Ginkgo Biloba supports circulation through several mechanisms: its ginkgolide B is the most potent known naturally occurring inhibitor of platelet-activating factor (PAF), it promotes vasodilation, and it improves blood flow in different vascular beds without significantly affecting blood pressure and heart rate. Multiple RCTs in patients with coronary artery disease and in healthy elderly adults have demonstrated increased blood flow and improved endothelium-dependent vasodilation.
Are these capsules suitable for people with dietary restrictions?
Yes. Nutricost Ginkgo Biloba capsules are gluten free, dairy free, soy free, and grain free. They are delivered in vegetarian capsules, making them suitable for individuals following vegetarian diets or managing common food sensitivities.
What are flavonglycosides and terpene lactones in Ginkgo Biloba?
Flavonglycosides (also called flavonol glycosides) are flavonoid compounds — primarily glycosides of quercetin, kaempferol, and isorhamnetin — that act as potent free-radical scavengers and contribute significantly to Ginkgo Biloba's antioxidant activity. Terpene lactones include the ginkgolides (A, B, C, J, and M) and bilobalide, which are found predominantly in Ginkgo Biloba trees. Ginkgolides and bilobalide have been described as up to 70–80% bioavailable and exert neuroprotective, anti-inflammatory, and PAF-inhibitory effects. Together, these two compound classes are considered the pharmacologically defining components of standardized Ginkgo Biloba extract.
