Ginkgo Biloba for Memory: I Read the Research So You Don't Have To

The Oldest Tree on Earth Has a Memory Problem (Sort Of)

Ginkgo biloba is one of the best-selling herbal supplements on the planet, and almost every dollar spent on it is spent for one reason: people want a better memory. The marketing practically writes itself. An ancient tree, a brain in a bottle, thousands of years of tradition.

I’ll be honest, I’m usually the skeptic in the room when a supplement promises to sharpen my brain. Most of them fold the moment you look at the actual trials. So I went in expecting ginkgo biloba and memory to be another marketing romance with no data behind it.

That’s not quite what I found. And that’s what makes ginkgo interesting.

Here’s the tension I want you to understand up front. Some trials show real cognitive effects. Meanwhile, the largest dementia-prevention trial ever run, the GEM study with 3,069 participants followed for years, showed nothing. Zero reduction in dementia risk. So which is it? A useful cognitive aid or an overhyped leaf?

The answer is “it depends entirely on who’s taking it,” and I’ll walk you through exactly where the line sits.

One more thing the marketers love. Ginkgo trees can live over 1,000 years, and a handful of them survived the Hiroshima bombing and are still standing today. It’s a genuinely amazing biological fact. It also tells you absolutely nothing about your hippocampus. A tree’s longevity is not evidence for your recall.

This article separates where the data is strong from where it’s pure sales copy. Let me be straight about both.

The Oldest Tree on Earth Has a Memory Problem (Sort Of)

What Is Ginkgo Biloba, Actually?

Ginkgo biloba is a living fossil. It’s the sole surviving species of a plant family that dates back more than 200 million years, which means these trees were around before dinosaurs went extinct. Every other member of its lineage is gone. Ginkgo just kept going.

Here’s a distinction most articles gloss over. Traditional Chinese medicine used ginkgo seeds. Modern supplements use an extract from the leaf. Those aren’t interchangeable, and the seeds actually carry toxicity concerns the leaf extract doesn’t. So when someone waves “thousands of years of use” at you, they’re talking about a different part of the plant than what’s in your capsule.

The extract that matters: EGb 761 and why standardization is everything

Nearly every quality study on ginkgo used one specific preparation: EGb 761. It’s a standardized extract with a defined chemical profile, and that consistency is the whole reason the research means anything.

The standard is 24% flavone glycosides and 6% terpene lactones. That ratio isn’t arbitrary. It’s the composition that got tested in the trials I’m about to cite.

Here’s the part that should change how you shop. A non-standardized ginkgo supplement is essentially an untested product, no matter what the bottle promises. If a product doesn’t state its standardization, you have no idea whether it resembles the extract that actually showed effects in humans. You’re buying green powder and hope.

The active compounds: flavone glycosides and terpene lactones

Two families of compounds do the heavy lifting. The flavone glycosides (flavonoids) handle the antioxidant activity. The terpene lactones split into ginkgolides and bilobalide, and these are the ones tied to blood flow and platelet effects.

There’s also a compound you want kept out. Ginkgolic acids are allergenic and potentially toxic, so quality extracts keep them under 5 ppm. Cheap products don’t always bother, and that’s a problem I’ll return to when we talk about testing scandals.

How Ginkgo Biloba Works for Memory: The Mechanisms

So what does ginkgo actually do inside your skull? This is where I got more interested, because the proposed mechanisms are real and measurable, not vague “supports brain health” hand-waving.

Blood flow: the vasodilation story

The most studied effect is on cerebral blood flow. Ginkgo increases blood flow to the brain through nitric oxide pathways and by improving blood viscosity, essentially making blood less sticky and vessels more relaxed.

Imaging studies have put numbers on this. Research using MRI in older adults has shown measurable increases in cerebral blood flow, with some middle cerebral artery flow increases in the range of 10 to 15% after supplementation. Mao et al. reported blood viscosity improvements and increased flow velocity in older participants taking standardized extract.

Think of ginkgo less like a memory pill and more like widening the supply roads into a city. You’re not adding factories. You’re just letting more traffic through. If a region of the brain was underserved by poor circulation, better roads help. If circulation was already fine, wider roads don’t do much. That single idea explains most of the confusing trial results.

Antioxidant effects on brain cells

The flavonoids scavenge free radicals, and this matters more than it sounds. The aging brain is unusually vulnerable to oxidative stress because it burns enormous amounts of oxygen and is packed with fats that oxidize easily.

Bilobalide and the ginkgolides have shown neuroprotective effects in cell and animal models, reducing markers of oxidative damage. That’s a plausible route to protecting neurons over time, though “plausible in cells” and “proven in humans” are different tiers of evidence, and I’ll keep them separate.

Neurotransmitters and platelet-activating factor

Ginkgolide B blocks something called platelet-activating factor, or PAF. This one compound explains both the good and the risky side of ginkgo. Blocking PAF may support blood flow and offer some neuroprotection. It also reduces platelet clumping, which is exactly why bleeding risk becomes a real concern (more on that later).

Animal studies have shown effects on dopamine and acetylcholine signaling too, and acetylcholine is central to memory formation. That’s genuinely encouraging. Here’s my honest caveat: rodent brains aren’t human brains, and neurotransmitter effects that look tidy in a mouse routinely evaporate in people. I trust the blood-flow story more than the neurotransmitter story, and the human data backs that hierarchy.

How Ginkgo Biloba Works for Memory: The Mechanisms

Does Ginkgo Biloba Improve Memory? Here's Where the Evidence Actually Stands

Let me give you my position before the details: the answer depends entirely on who’s taking it. Ginkgo for a healthy 30-year-old and ginkgo for someone with early dementia are almost two different questions with two different answers.

Healthy adults: modest at best

If you’re a healthy adult hoping ginkgo will make you sharper, I have bad news backed by good data.

Solomon et al., writing in JAMA in 2002, ran a clean trial on 230 healthy adults over 60. Standard doses, real duration, proper memory testing. The result? No measurable benefit on any of the memory or cognitive tests they used. That’s not a “trend that didn’t reach significance.” That’s nothing.

Smaller studies have occasionally reported flickers of improvement in things like speed of processing or attention in healthy people, but they tend to be tiny, short, and hard to replicate. My read: if you have a healthy, well-functioning brain, ginkgo isn’t going to add a gear you didn’t have.

Age-related cognitive decline and mild cognitive impairment

This is where the picture shifts. A meta-analysis pooling trials in older adults with cognitive complaints found small but statistically real improvements on some cognitive measures, particularly in people who already had some decline. The effect sizes were modest, not dramatic, but they were there.

That fits the blood-flow mechanism perfectly. In a brain where circulation and function have started to slip, widening the supply roads has something to actually fix.

Dementia and Alzheimer’s: the GEM trial changed everything

Here’s what stopped me. The Ginkgo Evaluation of Memory study, the GEM trial, was designed to settle the prevention question once and for all. It was enormous.

DeKosky and colleagues enrolled 3,069 adults aged 75 and older, gave them 240 mg of EGb 761 daily, and followed them for a median of 6.1 years. Published in JAMA in 2008, the verdict was blunt: ginkgo did not reduce the incidence of dementia or Alzheimer’s compared to placebo. Not even close.

A follow-up analysis in JAMA the next year, again from DeKosky’s group in 2009, looked at whether ginkgo at least slowed the rate of cognitive decline in that population. It didn’t. No effect on decline rate either.

So if your reason for taking ginkgo is “I want to prevent dementia,” the biggest, longest, best-funded trial in existence says save your money. I want to be crystal clear about that because it’s the single most oversold claim attached to this supplement.

Where ginkgo genuinely surprised me

And yet. Here’s the counterpoint that keeps ginkgo from being written off entirely.

When you look at people who already have dementia rather than healthy people you’re trying to protect, the story changes. A 2016 meta-analysis of 21 trials found that 240 mg per day of EGb 761 improved cognition and daily functioning in dementia patients, with the strongest effects in those who also had neuropsychiatric symptoms like agitation or apathy.

Treating existing impairment and preventing future impairment are separate goals, and ginkgo appears to help with the first while failing at the second. That distinction is the entire ballgame, and most US coverage misses it completely.

Which is why EGb 761 is actually an approved treatment for dementia in Germany and several other European countries. It’s not a fringe herb over there. It sits in clinical guidelines. American articles that dismiss ginkgo as useless are ignoring a regulatory reality on the other side of the Atlantic.

My honest takeaway: ginkgo won’t prevent decline in a healthy brain, and it won’t stop dementia from developing. But it has legitimate, if modest, data for early cognitive impairment and for symptom management in existing dementia. That’s a narrow but real window.

Ginkgo Biloba Dosage for Memory: What the Trials Actually Used

If you decide ginkgo fits your situation, dose matters more than almost anything else, and this is where drugstore products fall apart.

The 120 mg vs 240 mg question

The effective range across the research is 120 to 240 mg per day of standardized extract, split into two or three doses. But those two numbers are not equal.

Here’s the pattern I kept seeing: 240 mg per day is the dose used in nearly all the positive dementia trials. The 120 mg dose frequently underperforms, showing weaker or no effects in head-to-head comparisons. Dose-comparison data in dementia patients has consistently favored the higher amount. If you’re taking gingko for a cognitive reason with actual evidence behind it, 240 mg split into two doses is the number to match.

Look, if you’re a healthy person, I already told you the data doesn’t support much benefit at any dose. This section is for people in the impairment window.

Timing and how to take it

Take ginkgo with food. It can cause mild GI upset on an empty stomach, and food smooths that out. Peak plasma levels arrive roughly 1 to 2 hours after a dose, and splitting the daily amount keeps blood levels steadier than one big morning capsule.

Consistency beats timing precision here. The trials that worked dosed daily for months, not occasionally before a big meeting.

Why your drugstore bottle might not match the research

This is the part that genuinely irritates me. You can do everything right and still buy a useless product.

Watch out for three red flags. First, no stated standardization. If it doesn’t say 24% flavone glycosides and 6% terpene lactones, assume it wasn’t tested to match EGb 761. Second, proprietary blends that bury ginkgo alongside a dozen other ingredients at unknown doses. Third, whole-leaf powder, which is not the same thing as a standardized extract and shouldn’t be treated as equivalent.

Now the money. Quality standardized extract runs roughly $15 to $30 a month. When you see ginkgo priced suspiciously cheap, there’s usually a reason, and independent testing has repeatedly found it.

ConsumerLab and other independent testers have flagged ginkgo products over the years, and there have been genuine adulteration scandals where products were spiked with cheap flavonoids like rutin to fake the flavonoid content on paper. The label reads correct. The actual ginkgo isn’t there. That kind of fraud is depressingly common in this category, which is exactly why standardization and third-party testing aren’t optional extras. They’re the whole point.

Frequently Asked Questions

Q: What does ginkgo biloba do for memory? Ginkgo biloba increases blood flow to the brain and provides antioxidant protection to neurons. In people with early cognitive impairment or existing dementia, standardized extract has shown modest improvements in memory and daily function. In healthy adults, the memory benefit is minimal to nonexistent.

Q: How does ginkgo biloba work in the brain? It widens and relaxes blood vessels through nitric oxide pathways, reduces blood viscosity to improve cerebral circulation, scavenges free radicals that damage aging neurons, and blocks platelet-activating factor. Animal studies also suggest effects on acetylcholine and dopamine signaling, though human evidence for that is weaker.

Q: Is ginkgo biloba safe to take daily? For most healthy adults, standardized EGb 761 at 120 to 240 mg daily is generally well tolerated, with mild side effects like headache or GI upset being the most common. The main safety concern is increased bleeding risk, so it’s not appropriate for everyone (see the blood thinner question below).

Q: What is the best ginkgo biloba dosage for memory? The dose used in nearly all positive trials is 240 mg per day of standardized extract (24% flavone glycosides, 6% terpene lactones), split into two or three doses. The lower 120 mg dose often underperforms. Take it with food and stay consistent for several weeks.

Q: How long does ginkgo biloba take to work for memory? Don’t expect anything fast. Most trials showing cognitive effects ran for at least 8 to 12 weeks, and the meaningful dementia studies dosed for months to years. If you’re testing it, give it a solid 8 to 12 weeks at 240 mg daily before judging.

Q: Can ginkgo biloba prevent Alzheimer’s or dementia? No. The GEM trial, the largest prevention study ever run (3,069 adults over 75, followed 6+ years), found ginkgo did not reduce dementia or Alzheimer’s incidence, and a follow-up showed no effect on the rate of cognitive decline. It may help treat existing impairment, but it does not prevent it.

Q: Can I take ginkgo biloba with blood thinners like aspirin or warfarin? This is the combination to be cautious about. Ginkgo blocks platelet-activating factor and can reduce clotting, so pairing it with aspirin, warfarin, or other anticoagulants may raise bleeding risk. Anyone on blood thinners or facing surgery should treat this as a real interaction, not a hypothetical one.

Q: Is ginkgo biloba better than bacopa for memory? They target different things. Ginkgo works mainly through blood flow and suits age-related circulation issues and early impairment. Bacopa monnieri has stronger data for memory formation and learning in healthy adults over long-term use. For a healthy person wanting a memory aid, bacopa’s evidence is arguably more convincing.

How Long Does Ginkgo Take to Work?

Let me set expectations before you spend a dime. This is not caffeine. Nobody feels ginkgo on day one, and if a product promises you will, put it back on the shelf.

The realistic timeline

Here’s the strange part: the blood flow effects show up fast, but the memory effects don’t. Imaging work has shown measurable changes in cerebral blood flow within hours of a single dose. Mashayekh and colleagues at Johns Hopkins ran an MRI study in older adults and picked up modest increases in regional blood flow after just four weeks of EGb 761.

Functional memory outcomes are a different animal. Almost every trial that found a cognitive benefit ran for 12 to 24 weeks minimum before measuring anything. The dementia trials dosed for six months. GEM ran for over six years. Your brain doesn’t rewire its efficiency in a weekend because a few more milliliters of blood are moving through it.

So the honest window is 8 to 12 weeks at 240 mg per day before you’re even in the territory where the trials looked.

When to call it quits

Here’s the thing, most people quit at 3 weeks and most trials didn’t even test before 12. That mismatch alone explains a lot of the “ginkgo did nothing for me” reviews online.

My practical advice: commit to a fair 3-month trial at the full 240 mg dose of standardized extract, and track something measurable. Word recall games, a digit span app, even just journaling how often you lose your train of thought mid-sentence. If nothing budges by month three, stop. More time won’t rescue it, and your $15 to 30 a month can go somewhere with better odds.

Which raises the obvious next question. Is three months of daily ginkgo actually safe?

Is Ginkgo Biloba Safe? Side Effects and Interactions You Shouldn't Ignore

Short answer: for most healthy adults, yes. The GEM trial followed over 3,000 elderly adults for more than six years, and adverse event rates in the ginkgo group were basically identical to placebo. That’s about as good a long-term safety dataset as any supplement will ever have.

But “safe for most people” is doing some work in that sentence. Let me break down where it falls apart.

Common side effects (mostly mild)

The complaints that do show up are unglamorous: headache, stomach upset, dizziness, and the occasional allergic skin reaction. They’re infrequent, they’re usually mild, and taking ginkgo with food knocks out most of the GI issues. In placebo-controlled trials these rates often don’t separate from the sugar pill at all.

The bleeding risk question

This is the one that deserves real attention, and I’ll give you both sides.

The case reports are genuinely concerning. There are published reports of spontaneous bleeding, including subdural hematomas and eye hemorrhage, in people taking ginkgo. Ginkgolide B inhibits platelet-activating factor, so there’s a plausible mechanism sitting right there.

Then there’s the controlled data, which tells a calmer story. Kellermann and Kloft pooled 18 randomized trials in a 2011 Pharmacotherapy meta-analysis and found no significant effect of standardized ginkgo extract on platelet aggregation, coagulation parameters, or bleeding time. GEM’s six-plus years of data didn’t show excess bleeding events either.

So who’s right? Probably both. Ginkgo alone, at standard doses, in people with normal clotting, appears fine. The danger zone is stacking it on top of drugs that already thin the blood, or heading into surgery with it in your system. My stance: stop ginkgo one to two weeks before any surgery, no exceptions, and don’t combine it with anticoagulants without a physician actively supervising. The downside of being wrong here isn’t a headache. It’s a brain bleed.

Drug interactions that actually matter

Four categories worth flagging:

• Anticoagulants and antiplatelets (warfarin, aspirin, clopidogrel): the big one, covered above.
• SSRIs: theoretical serotonin concerns. The evidence is thin, but it’s on the radar.
• Anticonvulsants: ginkgo has been linked in case reports to reduced seizure control, and ginkgotoxin (found mainly in the seeds) actively lowers the seizure threshold.
• Diabetes medications: ginkgo may alter insulin metabolism in some people, so glucose monitoring matters if you’re on medication.

Who should skip ginkgo entirely

Never eat raw ginkgo seeds. I mean that literally. The seeds contain ginkgotoxin (4’-O-methylpyridoxine), which has caused seizures and deaths, mostly in children in East Asia where roasted seeds are a traditional food. Standardized leaf extract is a different product, but it’s worth knowing why “whole plant” is not automatically better.

Skip ginkgo if you’re pregnant, if you have a seizure disorder, or if surgery is on the calendar.

One more thing, because I’d rather you hear it from me than a scary headline. The National Toxicology Program published a 2013 rodent study where mice given very high doses of ginkgo extract developed liver tumors. Sounds alarming until you look at the doses: up to 2,000 mg per kilogram of body weight, gavaged daily. A human taking 240 mg is at roughly 3 mg per kilogram. That’s not a rounding error, it’s a 600-fold gap, and rodent liver tumor models translate poorly to humans at the best of times. I don’t lose sleep over it. I do think it’s another argument against megadosing.

Ginkgo vs Other Memory Supplements: An Honest Comparison

Ginkgo doesn’t exist in a vacuum. If you’re shopping for a memory supplement, it’s competing with three serious alternatives, and I have opinions on all of them.

Ginkgo vs bacopa monnieri

For healthy adults, bacopa wins, and it’s not particularly close. Kongkeaw et al. (2014) pooled nine randomized trials covering roughly 500 participants and found consistent improvements in memory free recall with bacopa in people without cognitive impairment. That’s exactly the population where ginkgo keeps failing. Ginkgo’s edge is the opposite scenario: age-related circulation decline and existing cognitive impairment, where its vascular mechanism actually matches the problem. Pick based on which person you are.

Ginkgo vs omega-3s

Omega-3s have the better long-game story. Observational data linking fish intake to slower cognitive aging is extensive. But when researchers test supplementation head-on, results disappoint: the OPAL trial gave omega-3s to 867 older adults for 24 months and found no cognitive benefit over placebo. I still take omega-3s, for the record, because the cardiovascular case stands on its own and a healthy vascular system is the best memory supplement there is. Just don’t expect them to sharpen recall in six months.

Ginkgo vs phosphatidylserine

Phosphatidylserine holds an odd distinction: it’s one of the very few supplements with an FDA qualified health claim for cognitive function in the elderly, granted in 2003. The FDA’s own wording calls the supporting evidence “very limited,” which tells you how low that bar sits. The older positive trials used bovine-derived PS; modern soy-derived versions have weaker data. Interesting, not compelling.

Can you combine them?

The one combination with actual trial support is ginkgo plus ginseng. Wesnes et al. gave the pairing to 256 healthy middle-aged volunteers over 14 weeks and recorded a measurable improvement in a memory index versus placebo. That’s a legitimate result.

The stacked “brain blend” products at your pharmacy? Mostly marketing. Look at the labels and you’ll find 60 mg of ginkgo, a sprinkle of bacopa, and fairy dust amounts of everything else. Underdosing every ingredient doesn’t create a super-supplement. It creates an expensive multivitamin that does nothing.

How to Choose a Quality Ginkgo Supplement

This section matters more for ginkgo than for almost any other supplement, because ginkgo is one of the most adulterated botanicals on the market. The Botanical Adulterants Prevention Program has documented widespread spiking of ginkgo products with cheap flavonoids like buckwheat-derived rutin, done specifically to fool standard lab tests. And back in 2015, the New York Attorney General’s investigation found major retailers selling “ginkgo” with no detectable ginkgo DNA at all.

So the label checklist isn’t pedantry. It’s the whole game.

The label checklist

• Standardization: 24% flavone glycosides and 6% terpene lactones, stated explicitly. This matches EGb 761, the extract used in virtually every positive trial.
• Ginkgolic acids under 5 ppm: these are allergenic compounds that proper extraction removes. Quality manufacturers state this; cheap ones don’t test for it.
• Third-party verification: USP, NSF, or ConsumerLab seals mean someone outside the company confirmed what’s in the bottle.
• A real dose: 120 mg per capsule minimum, so hitting 240 mg daily is practical.

Red flags to avoid

Whole leaf powder sold as equivalent to standardized extract is the biggest scam. Raw leaf contains a fraction of the active compounds plus the ginkgolic acids the extraction process exists to remove. Cheaper for a reason.

Proprietary blends hiding the actual ginkgo dose are red flag number two. If they won’t tell you the milligrams, assume the answer embarrasses them.

And any product claiming to “reverse memory loss” or “prevent Alzheimer’s” is making drug claims that its own ingredient failed to support in a 3,069-person trial. Walk away.

Storage is simple: cool, dry, away from light. The terpene lactones hold up well, but flavonoids degrade with heat and humidity, so don’t keep the bottle above the stove, and respect the expiration date.

My Bottom Line on Ginkgo Biloba and Memory

I told you at the start I’m usually the skeptic in the room, so here’s the verdict without hedging.

If you’re a healthy 30-year-old chasing sharper focus, skip ginkgo. The trials in people like you keep coming up empty, and bacopa or basic sleep hygiene will beat it. If you or a family member is dealing with early cognitive changes, poor circulation, or diagnosed mild impairment, ginkgo becomes a legitimate option worth discussing with the prescribing doctor, particularly since the European trial data at 240 mg is respectable in exactly that population.

The non-negotiables, if you try it: standardized extract (24/6), 240 mg per day, a full 3-month trial with something measurable to track, and genuine caution around blood thinners and surgery.

Ginkgo biloba has survived 200 million years, an ice age, and the atomic bomb at Hiroshima. It did not survive contact with a well-run prevention trial unscathed. That’s the whole story in one sentence: an ancient, resilient, genuinely interesting plant with real pharmacology, oversold for decades to the wrong audience. Give it to the right brain, at the right dose, for the right amount of time, and it might earn its place. Just don’t expect miracles from a tree, no matter how old it is.

FAQ: Ginkgo Biloba and Memory

Q: What does ginkgo biloba do for memory? Ginkgo biloba modestly improves memory and cognitive scores in people with existing cognitive impairment or dementia, mainly by increasing cerebral blood flow. In healthy adults, trials consistently show little to no memory benefit. It treats impairment better than it enhances normal function.

Q: How does ginkgo biloba work in the brain? Two active compound families do the work. Flavone glycosides act as antioxidants that protect neurons from oxidative damage, while terpene lactones (ginkgolides and bilobalide) improve blood flow by relaxing vessels and inhibiting platelet-activating factor. The net effect is better circulation and modest neuroprotection.

Q: Is ginkgo biloba safe to take daily? Yes, for most healthy adults. The GEM trial followed over 3,000 elderly adults for six-plus years with side effect rates similar to placebo. Exceptions: avoid it with blood thinners, before surgery, during pregnancy, and with seizure disorders. Never eat raw ginkgo seeds.

Q: What is the best ginkgo biloba dosage for memory? The dose used in nearly all positive trials is 240 mg per day of standardized extract (24% flavone glycosides, 6% terpene lactones), split into two or three doses. The lower 120 mg dose often underperforms. Take it with food and stay consistent for several weeks.

Q: How long does ginkgo biloba take to work for memory? Don’t expect anything fast. Most trials showing cognitive effects ran for at least 8 to 12 weeks, and the meaningful dementia studies dosed for months to years. If you’re testing it, give it a solid 8 to 12 weeks at 240 mg daily before judging.

Q: Can ginkgo biloba prevent Alzheimer’s or dementia? No. The GEM trial, the largest prevention study ever run (3,069 adults over 75, followed 6+ years), found ginkgo did not reduce dementia or Alzheimer’s incidence, and a follow-up showed no effect on the rate of cognitive decline. It may help treat existing impairment, but it does not prevent it.

Q: Can I take ginkgo biloba with blood thinners like aspirin or warfarin? This is the combination to be cautious about. Ginkgo blocks platelet-activating factor and can reduce clotting, so pairing it with aspirin, warfarin, or other anticoagulants may raise bleeding risk. Anyone on blood thinners or facing surgery should treat this as a real interaction, not a hypothetical one.

Q: Is ginkgo biloba better than bacopa for memory? They target different things. Ginkgo works mainly through blood flow and suits age-related circulation issues and early impairment. Bacopa monnieri has stronger data for memory formation and learning in healthy adults over long-term use. For a healthy person wanting a memory aid, bacopa’s evidence is arguably more convincing.
