Ginkgo biloba (Ginkgo or Maidenhair) is one of the oldest species of trees on earth. Scientists consider it a “living fossil” dating back 270 million years.[i] It has continued to survive even after major extinction events.
Gingko tress can grow to 130 feet (39.6 meters). Some Ginkgo trees in China are thought to be over 2,500 years old. And a 3,000-year-old tree reportedly stands in the Chinese province of Shandong.
Four Ginkgo trees survived the atomic explosion in Hiroshima. Only 1,130 meters from the bombs epicenter.
Gingko biloba has been used for medicine in China for several millennia. In the oldest Chinese Materia Medica (2800 B.C.), Ginkgo biloba was recommended for asthma, swelling of the hands and feet, coughs, vascular disorders, aging and for the brain.[ii]
An extract of Gingko leaves called EGb 761 is standardized to 24% flavone glycosides (flavonoids) and 6% terpenes (ginkgolides and bilobalides).
This Gingko extract regulates neurotransmitters, protects from brain cell degeneration, increases blood vessel microcirculation (blood flow in the smallest of blood vessels). And has antioxidant activity.[iii]
Ginkgo biloba helps:
- Neurotransmitters. Gingko biloba can increase dopamine in the brain. Ginkgo acts as a monoamine oxidase inhibitor (MAOI) which reduces levels of monoamine oxidase (MAO) in the brain. MAO breaks down dopamine.[iv] One of the benefits of boosting dopamine is to reduce anxiety.[v] And to treat ADHD.[vi]
- Cerebral Circulation. Ginkgo biloba increases cerebral blood flow. Improving oxygen and glucose availability to neurons for neuronal health. Improving memory, recall, cognition and learning.[vii] [viii]
- Neuroprotection. Ginkgo Biloba helps boost cerebral blood flow, reduces oxidative stress by eliminating free radicals, and increases nitric oxide which dilates blood vessels.[ix]

Overview
Ginkgo Biloba (Ginkgo or Maidenhair) is one of the oldest species of trees on earth. This “living fossil” has survived major extinction events for as long as 270 million years.
Gingko, also known as Maidenhair, has been used in Chinese medicine for millennia. Many of Ginkgo’s modern applications are based on research by German and Chinese scientists where it is a prescription drug.
The leaves have been used for thousands of years to boost mental alertness, improve cerebral circulation, and overall brain function.
As a nootropic, Ginkgo has been shown to be particularly effective in elderly memory loss, slow thinking and reasoning, and tinnitus. One study shows significant improvement in Parkinson’s and Alzheimer’s patients.[x]
EGb 761 is the standard extract of the Gingko referred to in the studies and clinical trials referred to in this article. It is standardized to 24% flavone glycosides (flavonoids) and 6% terpenes (ginkgolides and bilobalides).
How does Ginkgo Biloba Work in the Brain?
Ginkgo Biloba boosts brain health and function in several ways. But two in particular stand out.
- Cerebral circulation. Ginkgo boosts several brain functions by improving blood circulation in the brain.
A study in the Department of Radiology, at Johns Hopkins University School of Medicine used MRI’s to measure blood flow in 9 healthy men. MRI’s were done before and after the men took Gingko Biloba Extract 60 mg twice a day for 4 weeks.
The study concluded that overall, all regions of the subject’s brains showed a significant change in cerebral blood flow after using Ginkgo.[xi]
- Cognition and mental performance. Gingko is well known as a memory booster in the nootropics community. Studies have shown Ginkgo helps attention, mood and processing speed.
One large study at Liberty University, Lynchburg, Virginia was conducted with 262 healthy adults. This 6-week, double-blind, placebo-controlled trial had volunteers taking 180 mg of Ginkgo biloba extract, or a placebo daily for 6 weeks.
The subjects were put through several standardized tests. At the end of the 6-week trial, those using Ginkgo showed significant improvement in verbal and visual recall and memory.[xii]
How things go bad:
As we get older, our brain chemistry and energy metabolism changes. Blood vessels in our brain shrink and get narrower. Preventing the free flow of oxygenated blood to neurons. Toxic waste and free radicals accumulate within brain cells.
↓ Memory, recall, reaction time and mood diminish
↓ Critical neurotransmitters decline
↓ Chronic stress reduces memory capacity
All of these age-related changes are contributing factors to the neurodegenerative diseases of aging, including Alzheimer’s and dementia.
But even if you’re not concerned with the effects of aging, Ginkgo biloba can help.
Ginkgo Biloba to the rescue
Research from hundreds of studies have shown that Ginkgo biloba will:
- Improve memory and cognition[xiii]
- Increase reaction time
- Restore the availability of dopamine and other neurotransmitters
- Improve cerebral blood flow
- Reduce stress[xiv]
- Boost mood
- Help repair brain cells
- Act as an antioxidant to eliminate free radicals
How does Ginkgo Biloba feel?
Gingko improves circulation including in the brain. Thinking, reaction time, energy, and memory should improve. Cold hands and feet are often an indication of poor circulation and Ginkgo could help.
Ginkgo has a reputation for helping reduce the symptoms of tinnitus. And it’s also developed a good rep for helping erectile dysfunction (ED) in men.
Many neurohackers report it takes several weeks of continued use of Gingko to experience all the benefits this healing herb provides.
The Research
Age-related cognitive decline is expected as a normal part of aging in our society. This decline can lead to difficulty performing everyday activities like concentrating on what your loved one is saying. Or remembering to attend a family function you’ve been looking forward to for months.
This decline will affect your quality of life and affect your mood. And it’s happening to younger and younger people. But many of us in the nootropics community refuse to accept cognitive decline as “standard”.
Note: One important consideration we found in the research on Gingko Biloba. Some of the findings have been contradictory. Some indicating that Gingko does not work.
But the overwhelming impression we got from looking at decades of research was that Gingko Biloba takes a while to work. Often it can take many months of supplementation to see results. And extracts work far better than plain, powdered, ground Ginkgo.
Ginkgo Biloba Improves Cognition
Researchers in Germany set out to study the effects of Ginkgo Biloba in healthy adults. This randomized, double-blind, placebo-controlled trial worked with 66 health volunteers for 4-weeks. One group was given a placebo, and the other group took 240 mg of Ginkgo Biloba extract daily.
At the end of the trial, those taking Ginkgo Biloba extract saw significant improvements in their “self-perceived” mental health and quality of life. They performed far better on action and reaction tests. And reported a significant improvement in mood compared to those in the placebo group.[xv]
Ginkgo Biloba Improves Quality of Life
Another study with 1,570 men and women in England took either no dietary supplement or 120 mg of Ginkgo Biloba extract daily for 4, 6, or 10 months.
Participants who took Ginkgo extract experienced improvement in activities of daily living, mood and alertness compared to the control (who took nothing).
Activities of daily living included multi-tasking, completing household tasks, concentrating during a conversation, remembering important dates, and giving and following directions.
Measures of their mood included ratings of anxiety, depression, energy, drowsiness, sadness and happiness. Alertness factor rated whether they felt alert, clumsy, dizzy, relaxed and tired.
Participants in this study who took Ginkgo Biloba extract the longest reported the greatest improvement in all ratings measured. 10 continuous months of supplementing with Ginkgo extract was more effective than 4 months. Their life improved even more the longer they took Ginkgo Biloba extract.[xvi]
Gingko Biloba Improves Attention and Memory
Researchers at the University of Northumbria in the UK set out to determine if a single dose of Gingko would improve attention and memory in healthy volunteers. This placebo-controlled, multi-dose, double-blind trial worked with 20 people.
Participants were given either a placebo or single-dose of Gingko Biloba extract of 120, 240 or 360 mg. They were tested for their speed of attention, attention accuracy, memory speed and quality of memory. They were tested before the dose or placebo, and again at hours 1, 2.5, 4, and 6 hours.
The scientists reported that Ginkgo improved multiple cognitive performance measures. Most dramatic were with “speed of attention”. And results were better with the highest dose of 360 mg compared to the 240 mg dose.
This improvement was noted at the 2.5-hour mark. But was still noticeable 6 hours after supplementing with Gingko.
The researchers concluded that Ginkgo dosing can produce “sustained improvement in attention in healthy young volunteers”.[xvii]
Dosage Notes
Recommended dose of Gingko biloba is 40 mg 3-times per day. But daily dosage can range from 120 – 600 mg depending on the disorder being treated.
Most Ginkgo biloba products claim that a minimum of 4 weeks is required to achieve a boost in focus, memory and concentration.
Side Effects
There is the potential for an increased risk of bleeding when Ginkgo biloba is used concurrently with antiplatelet agents (e.g., aspirin, clopidogrel (Plavix®)), anticoagulants (e.g., warfarin (Coumadin®), enoxaparin (Lovenox®), heparin) or herbs with coumarin constituents (e.g., angelica, anise, capsicum, celery, chamomile, clove, danshen, garlic, ginger, horseradish, licorice, onion, papain, red clover).
Hypomania has been reported in patients with depression when Ginkgo leaf extract was used in combination with fluoxetine (Prozac®)/buspirone (BuSpar®), St. John’s wort, and melatonin.
Ginkgo leaf extract can alter insulin secretion. So patients taking insulin should monitor glucose levels closely.
There have also been reports of seizures associated with Ginkgo use with patients using medication used to lower seizure threshold. These drugs include propofol (Diprivan®), mexiletine (Mexitil®), amphotericin B (Fungizone®), penicillins, cephalosporins, imipenem/cilastatin (Primaxin®), bupropion (Wellbutrin®), cyclosporine (Neoral®), fentanyl (Sublimaze®), methylphenidate, and theophylline.
Ginkgo should be used with caution during pregnancy, due to the potential for increased bleeding risk. Ginkgo should be avoided during breastfeeding, due to a lack of sufficient data.
Available Forms
Gingko leaf is produced from green, picked leaves grown on plantations specifically developed for pharmaceutical purposes.
Ginkgo biloba extract is available in capsules, tablets, concentrated liquids, sublingual sprays, bars and cola drinks.
Standardized products should contain at least 24% flavone glycosides and 6% terpenes (ginkgolides and bilobalides). The products most commonly used in clinical trials are Ginkgo biloba standardized extracts EGb 761 (Tanakan) and LI 1370 (Lichewer Pharma).
Nootropics Expert Recommendation
Ginkgo Biloba extract up to 120 – 240 mg per day
We recommend using Ginkgo Biloba as a nootropic supplement.
Your body does not make Gingko biloba on its own. So you must take it as a standardized supplement.
Gingko biloba that has not been standardized to at least 24% flavone glycosides and 6% terpenes does not appear to be effective. So make sure you buy a standardized Ginkgo supplement.
Ginkgo increases alertness, focus, concentration and memory even in the young and healthy. Many neurohackers report immediate effects of supplementing with Gingko. But others find they need several weeks for the active compounds found in Ginkgo to take effect.
We suggest dosing up to 240 mg per day split into 3 doses throughout your day. But please refer to the “Side Effects” section of this article before you start using Ginkgo. It’s a powerful supplement and could interact with some medications.

Hi David!
Congratulations on the site and thank you for sharing this knowledge.
I weigh 125 Kg x 175 cm, I am obese and I don’t feel the effects of Ginkgo Biloba, I take 240mg of Ginkgo a day. Given my size, do you think I should take more? Same goes for theanine, I regularly take 350mg and don’t notice any significant effects, should I try 700mg or 1050mg? Respectively 2 and 3 capsules.
Andrea, it does not matter your size. Just follow the maximum recommended dosage for each supplement including 2 or 3-times per day. Make sure you’re using it with a healthy fat like unrefined coconut oil or MCT Oil.
If that doesn’t help then you’re using the wrong supplements for you.
ok I’ll try to take it with the oils you recommended! Take away another doubt … since Ginkgo Biloba is used for cerebral microcirculation, could it be possible that I don’t feel the effects because I actually don’t have microcirculation problems? At 37 years old, I think I stay healthy from this point of view, don’t microcirculation problems arise with old age? So if my microcirculation is at 95% and Ginkgo gives me that 5% more, the effects are imperceptible … What do you think?
Thanks David
Andrea, it’ll be very subtle if you felt it at all. Better to use Vinpocetine or Pine Bark Extract for blood flow in my opinion. You’ll feel it more.
but will it really be necessary to increase blood flow? Being 37 years old, I don’t think I have problems of this type …
Andrea, more blood flow is beneficial because it means more oxygen and nutrients are getting to brain cells.
Hi, David,
sorry, I wanted to ask you: in general, you can take 1 mg of melatonin and Ginko Biloba 120 mg (flavone glycosides 28.8 mg – terpene lactones 7.2 mg) before going to sleep, and then, take Vinpocetine in the morning as soon as awake?
Are there any contraindications to taking Ginko Biloba and Vinpocetine 7 hours apart?
Does Ginko Biloba Cause Tolerance? Can it be taken without a break? Or should it be suspended for three weeks every three months?
Likewise, does Vinpocetine cause tolerance? Can it be taken without a break? Or should it be suspended for three weeks every three months?
Thanks a lot and best regards. Demy
Demy you can not develop tolerance to Vinpocetine or Ginkgo Biloba. And yes they can be taken at the same time if you want.
Do you think it is safe to take lithium orotata with ginkgo biloba? Because it is generally believed that lithium should not be taken with MAO inhibitors.
Vadim, is should not be a problem. Because Lithium Orotate and lithium are not the same thing. “Lithium” generally refers to lithium carbonate and the like which is prescribed in very high doses to treat psychosis and mania. Unlike Lithium Orotate which is only 5 mg.
Hi David I have low reasoning(conclusive) level what nootropic will solve my problem?
Tamir, if you are referring to decision-making then absolutely nootropics can help.
Here is an article I wrote on learning and memory. It’s kinda’ intense and you’ll likely need to read it a few times. But it does contain suggestions on what you can try to improve decision-making and executive function.
https://nootropicsexpert.com/best-nootropics-for-learning-and-memory/
Regarding using concurrently with anticoagulants. Is it that ginkgo is good for anticoagulation? I.e. a nature way of breaking up clotts instead of using pharmaceuticals?
Robert, that is correct. Not sure it can be used “instead of” but worth trying.
Hi David,
Thank you as always for taking time to answer me! It does say in your article that reports of seizures were seen when taking Ginkgo with Wellbutrin and Methylphenidate that were prescribed to lower seizure threshold. I take both of these but I never had a seizure and I take them to attenuate the sedation of a tricyclic medication I use and my prescription for both has nothing to do with seizures.
Should I still avoid Ginkgo? If not, It seems like I should take it during the day, should I also take a dose at night?
Thank you
Rifat, each of us is different in how we react to supplements. If you haven’t had any problems with Ginkgo then I don’t see any reason not to use it. Whenever you find it beneficial.
Hi David,
I am looking to add Ginkgo supplement 60 mg (combined with DMAE 20 mg, Magnesium 150 mg) to my nootropics stack, but I am not sure about possible interactions.
I am currently taking Silexan (lavender oil) and recently add another supplement containg L-tryptophan (170 mg), 5-HTP (50 mg), Magnesium (50 mg) and B6 (0.9 mg).
Can I take Ginkgo supplement alongside with the above supplements?
I am looking to improve my overall anxiety and brain health.
Thanks in advance.
Peter, you can certainly try Gingko and see if it helps. DMAE really needs to be used with a choline supplement because of the way it works. And a good B-Complex is better than just B6.
I see, its the stack in one supplement I have bought Ginkgo + DMAE + Magnesium. I didnt know about the additional choline supplementation, thanks for that.
Regarding the 5 HTP supplement (L-Tryptophan + 5-HTP + Magnesium + B6), I will most probably cut it as it makes me more anxious and I dont like the risks of 5 HTP.
I will most probably go for Inositol instead of this as I am more stable on it.
Is there is any problem to combine the Inositol with the Ginkgo supplement and Silexan (lavender oil)?
I did not find almost any dangerous interactions for Inositol, but asking just in case.
Keep up the good work on the site. It is very helpful and its my first stop, when I need information about supplements.
Peter, it’s likely 5-HTP that is making you feel anxious. And why I do not usually recommend using 5-HTP. Inositol is a good choice. Let us know how it works for you.
Hello David
Can ginkgo biloba has effect on prolactin levels ?
Thanks
Serge, Ginkgo reduces prolactin levels in rats: https://pubmed.ncbi.nlm.nih.gov/18001735/. Not sure about humans but it’s likely the same.
Hi David.
I would like to know if I should take the ginkgo biloba capsule with a meal or on an empty stomach. Which option can guarantee better absorption?
Fabio, I believe some of the flavonoids and terpenes in Ginkgo are fat-soluble. So will work best if taken with a meal containing healthy fats.
Thanks David
How many mg per day of gingko to use to lower prolactin levels
Serge, no definitive answer to your question. Just know that is does. I suggest trying the lowest recommended dose for a few days and see if that helps. If there are no negative side effects then you can increase your dose.
Hello David
Can gingko lower high prolactin levels?
Serge, animal studies show that Ginkgo is effective in lowering high prolactin levels: https://www.ncbi.nlm.nih.gov/pubmed/18001735. I haven’t looked for them but imagine there are human studies supporting this as well.
Hi David,
I’ve noticed I have been getting this rush of my skin getting flush and even a shortness of breath with my Nootropic stack. It is currently:
–>Mind Lab Pro and the following:
-Panax Ginseng
-Magetin
-Gingko biloba
-St. Johns Wort
-GABA
-Cat’s Claw Bark
-Ashwaganda
My goal with this stack is to have a subtle increase in cognition and clarity while reducing daily anxiety.
I thought it was the Panax creating this rush but am starting to think it is Gingko after cutting out Panax today. I feel like my mind is going on hyper drive (not in a bad way) but it’s a little too much for me.
Do you have any thoughts?
Cronin, it could be because Ginkgo acts as a monoamine oxidase inhibitor (MAOI) which reduces levels of monoamine oxidase (MAO) in the brain. Which then boosts dopamine and possibly serotonin.
But this is also a symptom of too much magnesium. It could be you are using too much Magtein.
Best thing is check our the “Side Effects” section for each of these nootropics here on Nootropics Expert. You may come across something that we’ve missed here.
Hi David,
I’m taking medication for type 2 diabetes (Metformin and Jardiance). Is it safe to include Ginkgo in my stack? Any dosage-related issues? Thanks.
Lawrence, Ginkgo leaf extract can alter insulin secretion. So if you decide to use it just please keep a close eye on your glucose levels. But depending on what you are trying to achieve you may want to choose another supplement.
Hi David,
I’m thinking about taking ginkgo but there are countless reports of ginkgo causing internal brain bleeding even without any other factors or medications. Just Gingko alone caused bleeding. Any thoughts on these articles? Does ginkgo really cause bleeding even without any other contributing factors?
Shawn, I’d need to see clinical proof of this side effect and not just anecdotal evidence from some website or book.
Hi David,
Thanks for responding. These are just articles I read online but I just wanted to make sure it’s safe without any risks for bleeding, I tried it and got headaches, not really sure why.
Shawn, go back to the “Side Effects” section of this review above. There is plenty of clinical evidence of Ginkgo causing bleeding under certain circumstances.
It also affects insulin secretion which may be why it caused headaches for you. Insulin is involved in brain glucose metabolism. Not sure how that relates to headaches but it could be the cause.
I was curious if anybody else here has had experiences when taking Gingko before sleep. I did it as an experiment a couple of times and noticed that I’d have lucid dreams. Not a complaint but any explanation for this?
KG, lucid dreams may be because Ginkgo increases cerebral blood circulation and boosts dopamine.
Hi sir, i request your guidance on the topic that i have noticed that the morning after a sexsual intercourse come for me with fatiuge decline in attention and laziness ,can you tell about usage of nootropic that can be done to avoid this situation ?
Lokendra, it depends on what is causing the fatigue. And I’m not talking specifically about sex here. It could be a depletion of neurotransmitters like dopamine. Or it could be mitochondrial fatigue. Or something else.
It will take some experimenting until you find the right combination of nootropics for your situation. For example, you could try L-Tyrosine to boost dopamine and CDP-Choline to increase acetylcholine and see if that helps.
David, your information may be the answer to my struggle to find a solution to RLS, which I have just begun to realize may be a low dopamine situation. Thank you so much for your research into Ginko Biloba. I am going to try it.
Hi David,I was just wondering if it is safe to take ginkgo with mind lab pro and I also take Ashwaganda thanks Don.
Don, it is safe and there are no contraindications that I’m aware of. But I’d start with the lowest recommended dosage for each additional nootropic and see how it goes.
hi David and everybody, I would like to know what this quote means literally (in details) : “There is the potential for an increased risk of bleeding when Ginkgo biloba is used concurrently with antiplatelet agents (e.g., aspirin, clopidogrel (Plavix®)” ? what risk are we talking about on here? bleeding, what kind of bleeding is it? if the person is not a pregnant nor injured or has a wound or cut!
I got a stroke and a right internal carotid artery stenosis since end of October 2018, and the neurosurgeon did put me on aspirin 100 and plavix 75, but I am reallly trying to get rid of them and substitute them with ginko, and can’t find any doctor who agrees me on that evening the other doctor who is a vascular surgeon. so my plan is to take the risk on my own for several days 3-7 days using ginko and stopping aspirin and plavix, and perform blood tests such as pt, ptt and platelet in CBC. and if it was good then that means no need for aspirin and plavix and I can be on ginko for a year or two. I have read the whole article about ginko and seen multiple YouTubes and I feel that it would be a help for my recovering. any clues?
all love
Khaled, I can’t advise you to stop aspirin or Plavex or tell you with confidence that either can be replaced by Ginkgo. But studies show Ginkgo significantly increases blood flow. However, I’m not sure about its anti-clotting benefits if that’s what you need in your situation.
Two other nootropic supplements that significantly boost blood flow and are worth researching here on Nootropics Expert are Vinpocetine and Pine Bark Extract. https://nootropicsexpert.com/nootropics-list/
Hello David and Khaled, I found this a few years ago and use it to replace Aspirin which causes severe problems with the stomach. I tried Nattokinase 2,000 FUs it’s from a “Fermented safe Soy-based Natto”, like Tempeh, & Miso, and is non-GMO, according to the Doctors Best brand. At my age of 75, I use it when I fly as a precaution to thin the blood because I am anti-Big Pharma FDA scum bag medicines. The only time I go to the Doctor is for Blood Tests as soon as he talks Dangerous FDA petro-chem prescriptions, I am out of the Surgery, like a rat up a drainpipe Regards Gordon
My Ginkgo Biloba is written 6000Mg. is it dangerous and should i discard it away for safety reasons?
George, most of the clinical studies I researched used Ginkgo Biloba extract and not plain Ginkgo powder. But 6,000 mg does seem a little much.
I suggest checking out the manufacturer’s website and see what they recommend. And the reviews for wherever you bought the supplement.
Hi David, I currently take Rhodiola and ashwaganda can you tell me if ginkgo biloba would be appropriate to add?
Jon, Bacopa may help and side effects are rare so worth trying.
Hi david,
My supplement brand are dosed up to 500mg, should I be cautious ? ( 120 LBS is my weight )
> 24% flavones (6,2mg) 6% lactones (1,5 mg)
Aeris, if you are using Ginkgo capsules I’d take the capsule apart and discard half of the 500 mg content.
David,
Curious if you’ve undergone genetic testing to see if any methylation issues may be at the root of your ADHD issues? I’ve been barking down this path for 8 years trying to unravel the mysteries of why my son’s autoimmune disease is refractory to the “gold standard” of immunosuppression.
Epigenetics seems to be the answer, but trying to find someone well-versed in that area is proving very difficult.
Thank you for this well-written and informative space.
Best, Lynn
Lynn, I have had genetic testing done for methylation issues. Dr. Mark Hyman has done some work in this area. And a couple of other integrative medicine doctors. Have you tried doing a search for “testing for methylation defects” and variations on that keyword theme?
thanks a lot for this helpful article.
I’am taking Ginkgo extract ( tablets 120mg), is it okay to take L-theanine too.
Emarceen, Gingko and L-Theanine should work well together. The synergy effect of these two works well.
Where is a good source to buy EGb 761 powder? I’m struggling to find it anywhere.
Jackson, not sure about powder or what country you are in. The only EGb 761 Gingko I could find in the USA is this one but it’s tablets: https://amzn.to/2ysU4YA
Reduce the dose? Thanks for great research on that. any thoughts on anything that may strength optic nerve?
Andy, I haven’t done a lot of research on eye health although your eyes are intricately involved and connected to your brain. I know that Vitamin B12 helps prevent macular degeneration: https://nootropicsexpert.com/vitamin-b12-cobalamin/. I suspect some of the other Vitamin and minerals would be powerful ways to strengthen the optic nerve as well. I’m just finishing up a post on minerals that will be published in the next day or two.
Anything that helps build “myelin” should benefit the eyes as well because the optic “nerve” is likely protected by a myelin sheath. Which needs certain vitamins, minerals and a couple of nootropics as I recall to synthesize and build myelin.
When I have taken Gingko, It made feel very tired. Any thoughts?
Andy, what form of Ginkgo were you using? Are you taking any other nootropic supplements or prescription medications? Do you have any health issues you are dealing with or aware of?
It was through Life Extension and I have Glaucoma
I use Lumigan and at the time of Gingko use I also used Timolol. Both are Beta blockers
Andy, Gingko acts like a monoamine oxidase inhibitor (MAOI). Beta blockers can increase the potency of MAOI’s which can lead to an unexpected drop in blood pressure. Resulting in feelings of fatigue and dizziness if you are standing up.
