Ginseng is known for calming anxiety, and boosting attention, concentration and memory.

Ginseng is one of the most popular and well researched herbal medicines in the world. It has been used in North America and Asia for thousands of years.

In all, there are 11 species of ginseng. But the name “ginseng” as a nootropic usually refers to either American ginseng (Panax quinquefolius), or Asian ginseng (Panax ginseng). Panax means “cure-all” in Greek.


Researchers in thousands of clinical trials have reported on the efficacy of ginseng for; anti-stress, cognition, memory, anti-wrinkle, flu, digestion, diabetes, erectile dysfunction, blood circulation, immune deficiency, menopause, anti-oxidant, cancer and much more.

Ginseng is rich in various pharmacological compounds. Including a series of polyacetylenes, polyphenolic compounds, acidic polysaccharides, and tetracyclic triterpenoid saponins (ginsenosides).

Both American and Asian Ginseng contain ginsenosides which researchers believe are the most active ingredient.

Here we are investigating ginseng as a nootropic.

Ginseng helps:

  • Mood and Stress. Ginseng helps improve mood and reduce stress. It works as an adaptogen, reducing adrenal fatigue, boosting GABA and providing an anti-stress effect.[i]
  • Neurotransmitters. Ginseng provides neuro-protective effects on the dopaminergic-pathway which can help with ADHD.[ii] And ginseng is a serotonin and norepinephrine reuptake inhibitor. Working as an antidepressant and helping some symptoms of ADHD.[iii]
  • Brain Energy. Ginseng acts as an anti-inflammatory by reducing cytokines. And as an anti-oxidant. Boosting ATP production in mitochondria, in part because this antioxidant effect shields mitochondria.[iv]


Ginseng is the most famous medicinal herb in Asia. It must be grown for 5 years before its harvested. The maturity of the plant influences the density of active compounds beneficial to human health.

Ginseng Root shaped like human legs
Ginseng Root

The term “ginseng” comes from the Chinese word ‘rénshēn’ (person + plant root). Because the root shape of ginseng resembles the legs of a human.

“Panax” comes from the Greek ‘pan’ (all) and ‘akos’ (cure). In traditional Asian medicine ginseng was used for many different issues affecting human health. An “over-all” cure.

The four largest producers of ginseng are South Korea, China, Canada and the U.S, with Canada being the largest exporter. The largest consumer of ginseng is South Korea.

South Korea also conducts the majority of research on ginseng. With 1,000 scholars who publish at least 100 research papers per year.[v]

The two primary ginsengs used for brain function are Asian Ginseng (Panax ginseng), and American ginseng (Panax quinquefolius).

Ginsenosides increase protein synthesis and the activity of neurotransmitters in the brain. And ginseng stimulates the formation of blood vessels and improves blood circulation in the brain. Which improves memory and cognitive abilities.[vi]


How does Ginseng work in the Brain?

Ginseng boosts brain health and function in several ways. But two in particular stand out.

  1. Ginseng boosts physical and mental energy. Many of us deal with a lack of energy and chronic fatigue nearly every day. In today’s world, and particularly in Western society, we’re suffering from mental and physical fatigue. From overworked, stressed students to seniors.

But this kind of fatigue is not a natural offshoot of ‘getting older’. Often it’s difficult to pinpoint what exactly is causing this fatigue. And the first thing most of us think of is reaching for an energy drink, caffeine, or a prescription stimulant.

While these options may work in the short-term, they don’t produce natural energy in your body. This is where ginseng comes in and saves the day.

One double-blind, placebo-controlled trial with 30 healthy young adults demonstrated Panax ginseng’s cognitive benefits.  The study found that a single dose of 200 mg or 400 mg of ginseng reduced blood glucose levels. And significantly reduced mental fatigue.[vii]

  1. Ginseng improves memory and learning. Most people who use ginseng report feeling more alert. And several trials show Asian ginseng can improve thinking and learning. Some of the research shows Panax ginseng can boost performance on mental arithmetic, concentration, and memory.

One example of several that show how ginseng seems to affect memory and learning is by boosting nerve growth factor (NGF) and neurite growth in the brain. This study was done on chicks with the ginsenoside Rb1.

The researchers found this ginseng extract significantly potentiated NGF and showed neurite outgrowth. [viii]

Ginseng boosts nerve growth factor

How things go bad

Our brain chemistry and energy metabolism are constantly changing. And any number of factors from chronic stress to disease and environmental factors can degrade cognitive function.

↓ Memory, recall, reaction time and mood decline

↓ Neurotransmitters and cellular signaling breakdown

↓ Chronic stress reduces memory capacity and overall brain health

↓ Nerve growth factor and neurogenesis decline

↓ Free radicals and inflammation damage brain cells

↓ Immune system is compromised

All of these changes can happen at any age. And are certainly contributing factors to age-related cognitive decline.

Ginseng benefits

Panax ginseng (Asian) and Panax quinquefolius (American) contain a collection of active compounds called ginsenosides. These triterpenoid saponins (plant chemicals) are unique to the ginseng species of plants. And are steroid-like in nature.Ginseng active compound - ginsenosides

Here’s a mind-blowing statistic; well over 100 different ginsenosides exist.[ix] The major ones are designated Ginsenoside Ro, Rb(1), Rb(2), Rc, etc. All are extracted from the rhizome (root) of the ginseng plant.

You’ll notice if you’ve reviewed any of the other nootropics listed on that I usually include a diagram of the active chemical compound in that nootropic.

In this case I’m not including the diagram because each compound extracted from ginsenoside is different. And there are dozens of them.

Each ginsenoside has a unique effect in your body and brain. And is often even metabolized differently in your digestive system.

Other components of ginseng include;

    • Polysaccharide ‘Ginsan which is an immune system modulator[x]. Ginsan is likely what helps tame inflammation in the brain. Which helps a host of cerebral functions like; neurotransmitters working more effectively, prevents apoptosis (cell death), improves memory, mental energy and more. Anti-inflammatories or not talked about much in the nootropics community. And I think in the future you’ll be hearing a lot more about how important they are to cognitive health and brain function.
    • MicroRNA’s which are gene modulators. Researchers have recently identified up to 73 MicroRNA’s in ginseng.[xi] These tiny non-coding molecules are capable of regulating the gene expression in the DNA of your brain cells. Which is an extremely complex subject in itself. And have the potential to affect nearly everything that happens in your brain.
    • Polysaccharides which have anti-cancer effects. Another subject not talked about in nootropic circles. But fundamentally important to brain health.[xii]
    • The amino acids L-Arginine and GABA (gamma-aminobutyric acid), and glutamate.[xiii] The neurotransmitter GABA is naturally produced in your brain and provides anti-anxiety and calming effects. Likely why supplementing with ginseng has a calming and anti-anxiety effect.

Several books could be written on how ginseng affects your brain. Including its appetite-suppressant qualities, ability to boost cognition, reducing fatigue, reducing depression, anxiety, stress, improving memory and learning, as a neuroprotectant, and increasing cerebral blood flow.

How does Ginseng  feel?

Supplementing with ginseng should boost your energy levels, both physical and mental energy. Ginseng has stimulant-like qualities and should help if you’re dealing with chronic fatigue. But unlike standard stimulants, your boost in energy will come with a more ‘relaxed’ feel.

Ginseng can boost mental alertness. And thinking should feel quicker and clearer. Recall and long-term memory should improve.

Ginseng also boosts your immune system so you may be able to avoid the flu or a cold. Ginseng is particularly helpful for anyone with a compromised immune system. And if you’re living with, or working around anyone else who is sick.

Ginseng Clinical Research

Much of the research on ginseng comes out of South Korea. And much of this research has been done with Asian ginseng (Panax ginseng). Showing how Panax ginseng improves cognitive function.

American ginseng (Panax quinquefolius) has a somewhat different ginsenoside profile from Panax ginseng. And it too shows promise in benefiting human cognition.

American ginseng boosts working memory

One double-blind, placebo-controlled trial was conducted with 32 healthy young adults. In this trial, researchers used a highly standardized extract of American ginseng (Cereboost™). Cereboost™ is Panax quinquefolius standardized to 10.65% ginsenosides.

This trial used doses of 100, 200 and 400 mg of standardized ginseng. And participants’ mood, cognitive function and blood glucose were measured at 1, 3 and 6 hours after taking the ginseng extract.

The researchers found that standardized American ginseng provided a significant improvement in working memory. Reaction time accuracy and ‘calmness’ significantly improved at just the 100 mg dose. And improved with higher doses.

The scientists concluded that there was, “robust working memory enhancement following administration of American ginseng”. And these effects are distinct from that of Asian ginseng.

The two ginsengs have different psychopharmacological properties that depend critically on ginsenoside profiles.[xiv]

The bottom-line of this study is that the kind of ginseng you use makes all the difference.

Panax Ginseng Protects & Fuels Brain Mitochondria

A stroke is caused by insufficient blood flow to that part of the brain where the stroke occurs. Lack of blood flow shuts down the oxygen and nutrient supply to brain cells. And things start to break down in the heart of the cell’s energy center – the mitochondria.

This study was done in the Neurology Department at Xijing Hospital in China. Researchers wanted to find out if ginsenoside Rd, one of the major active ingredients in Panax ginseng could protect the brain from stroke.

Rats were given ginsenoside Rd and then subjected to a stroke by reducing blood flow to part of their brain. (Note for gratitude journal – I’m thankful I’m not a lab rat).

The scientists found this Panax ginseng extract protected the rat brain from stroke. And it appeared to do it by protecting brain cell mitochondria from dysfunction, and apoptosis (cell death).[xv]

Researchers also demonstrated that ginseng activates multiple enzymes in the Krebs cycle. This helps mitochondria produce maximum energy in the form of ATP from glucose.[xvi] Which is one of the reasons why supplementing with Ginseng boosts mental energy.

Ginseng Improves Mental Performance

Actoprotector is a new term given to natural compounds that increase mental performance. And enhance your body’s ability to withstand physical loads without increasing oxygen consumption.[xvii]

Actoprotectors are a new subclass of adaptogen that increase physical performance.  And some extracts of Panax Ginseng are considered Actoprotectors.

The main difference of Actoprotectors and psychostimulants (caffeine, Ritalin, modafinil, adrafinil, etc.) is that Actoprotectors cause no increase in oxygen consumption or heat production.

The results in improved mental and physical performance are similar. But there’s no “crash” in 4 hours like you get from using a stimulant like Ritalin. You don’t experience the same kind of ‘mental load’ when using ginseng.[xviii]

Ginseng’s steroid-like phytochemical called ginsenosides are what provide this stimulant-like action in the brain. And an improvement in overall quality of life.

One report in 2003 evaluated 9 clinical trials done with humans with ginseng doses from 80 – 400 mg. Study duration spanned 2 – 9 months. And nearly every study evaluated demonstrated some improvement in Quality of Life score.[xix]

Ginseng Recommended Dosage

Dosage of ginseng depends on the extract used, and the quality of the extract. And results seem to be largely dependent on the quantity used.[xx]Ginseng dosage recommendation

To complicate things even more, ginseng dosage depends on the region where its grown, extract strength, and individual needs.

The Chinese for example recommend 2 grams daily while in Europe, the suggested range is 100 – 400 mg daily.

Many naturopaths recommend cycling ginseng. Use it for 3 to 4 weeks and take a week break. Remember, ginseng has steroid-like active compounds. So taking it for extended periods without a break is not recommended.

Ginseng has been and continues to be extensively researched. These doses are based on clinical trial data:

  • For stress, anxiety or fatigue: 1-gram ginseng daily dosed 500 mg twice per day
  • For Type 2 diabetes: 200 mg per day
  • For erectile dysfunction (ED): 900 mg of Panax ginseng 3-times per day

The bottom-line is to stay within the dosage recommended by the ginseng supplement manufacturer.

Ginseng Side Effects

Ginseng is a natural supplement and side effects are generally mild. But it can act as a stimulant in some people. Which can cause anxiety and insomnia.

Long-term use or higher than recommended doses can cause headache, dizziness and stomach upset. If you’re going to use ginseng you should cycle your dosing. Use the recommended dose for 3-4 weeks and take a week off before dosing again.

Women may experience menstrual changes when supplementing with ginseng.

Ginseng is NOT recommended by the under-18 neurohacker. Or women who are pregnant or breastfeeding.

Ginseng may affect blood sugar levels. So if you’re taking drugs for diabetes, check with your doctor first before supplementing with ginseng.

Ginseng can interact with:

  • Blood-thinning medications
  • Antidepressants
  • Antipsychotic medications
  • Stimulants including caffeine, Ritalin, Adderall, modafinil, adrafinil, etc.
  • Morphine

Types of Ginseng to buy

Ginseng supplements are made from ginseng root and root hairs. It’s available in dried, powdered, capsule and tablet forms.

Ginseng is also included in some nootropic stacks and other combination supplement formulas. Some with patented ginseng extracts like Cereboost™, GS15-4, and others.

Experienced users of ginseng seem to prefer American Ginseng (Panax quinquefolius) over Asian Ginseng (Panax ginseng). Each is a unique species of ginseng but both have ginsenosides.

But American Ginseng is cultivated under stricter conditions avoiding pesticides and herbicides. And the colder growing climate encourages higher concentrations of the active ingredients in ginseng.

When buying American ginseng, look for Panax quinquefolius. And when buying Asian ginseng, look for Korean, red or Panax ginseng.

And finally, make sure you buy from a reputable supplement maker. Very recently GNC, Target, Walgreens and Walmart stores in the U.S. were found to contain either contaminants or little to zero ginseng. Walgreens ginseng brand was found to contain nothing but garlic powder and rice.[xxi]

Nootropics Expert Recommendation

Ginseng 100 – 400 mg per day

Nootropics Expert Tested and ApprovedI recommend using Ginseng as a nootropic supplement.

Your body does not make Ginseng on its own. So you must take it as a standardized supplement.

Ginseng is especially helpful for chronic fatigue. And a great way to provide a natural physical and mental energy boost.

Ginseng provides anti-anxiety and calming effects. And can boost mental alertness, memory, recall, and learning.

Ginseng is a powerful adaptogen that has been used for thousands of years. The ancient Chinese and other cultures used it for overall health.

We suggest starting with a dose of 100 mg daily. You can safely boost it to 4-500 mg per day depending on the brand and extract.

But remember that ginseng has steroid-like qualities. So make sure you cycle it. Use it for 3-4 weeks and take a week off. And don’t take it late in the day as it may interfere with sleep.

Many neurohackers prefer American over Asian ginseng. It has a slightly different ginsenoside profile. And is grown under stricter conditions ensuring quality and safety.

Hi there,
I saw your ADD article.
Can ginseng be stacked with ritalin?
Thank you!

    David Tomen
    October 26, 2023

    Andrei, theoretically it can be stacked with Ritalin but you may get too much of a stimulant effect.

May 18, 2023

Hello David, how are you?
I have been consuming Panax Ginseng daily for months and I fear I am making a serious mistake
I would like to know please, what is the worst that can happen to me if I do not cycle the consumption of Panax Ginseng?

    David Tomen
    May 26, 2023

    Valentina, long-term use at higher than recommended doses of Ginseng can cause headache, dizziness and stomach upset. If you start feeling those symptoms you’ll know to take a break for a couple of days every week of using Ginseng. If you do not get any bad effects then you do not have anything to worry about.

      May 27, 2023

      Thanks for answering David, but my question was misinterpreted because I didn’t write it correctly, here I go again, I was referring to the part you mentioned “Remember, ginseng has steroid-like active compounds. So taking it for extended periods without a break is not recommended.”, How serious can it be not to cycle it referring to “steroid-like active compounds”? (I consume 400 mg a day)

        David Tomen
        May 28, 2023

        Valentina, you did not misunderstand. If you have been using Ginseng for months without a problem you can assume you can continue to use this supplement with no problem. IF there was a problem it would be any of those I described in my first comment above.

January 12, 2023

Hey David, thanks for the info! I just started taking 200mg of Panax Ginseng and I have 2 questions:

– I also take maca root powder (2-3g) every morning without cycling. And I am considering introducing Tongkat Ali as well. Is it alright to combine all these 3 extracts or might they interact with each other?

– I was thinking of cycling Panax Ginseng doing 5 days on and 2 days off every week. Do you consider it better to cycle it on a monthly scale (as you suggested 3 weeks on and 1 week off)?

Thanks in advance and I much appreciate all the info you give us on nootropics!

    David Tomen
    January 13, 2023

    Marco, there are no studies showing a contraindication between those 3 supplements. And as far as I can tell there should not be a problem.

    If you’ve been around here for a while you’ll know that I am not a fan of cycling. There are very, very few supplements that need to be cycled as long as you are following recommended adult dosages per day.

    Some say they have better results by cycling Ginseng. But I personally do not see any benefit to cycling this supplement. It either works for you or it doesn’t. The only way to find out if it does or doesn’t is by trying them.

Do you have any idea why perfectly healthy people get depression and anxiety after covid? What happens in the brain and body? What causes this?
How can those people recover?

    David Tomen
    November 16, 2022

    Hans, it’s now called Long COVID and it looks like it affects about 25% of the people who get this virus. Studies have found those with COVID completely depleted of NAD+, Vitamin C and selenium.

    The results of all this include problems with serotonin and L-Tryptophan, leading to histamine release and mast cell activation issues. And I could go on and on. If you’d like help putting together a Long-COVID stack then schedule a consultation with me and I’ll walk you through what has been found to help.

November 3, 2022

Thank you David for the wealth of information and research you have provided. Do you have a specific brand of ginseng you trust and you or others have found to actually work? I have used my fair share of popular brands available online (“Now” Brand and others) and the have been ineffective at best, I do not even experience a placebo effect.

    David Tomen
    November 3, 2022

    JC, I have been using this one: and it seems to be effective if you use it 3-times per day.

      November 3, 2022

      Thank you! Will look into it immediately.

October 4, 2022

Hello david,

I got one quick question.

I have recently received your newsletter on my mail box and I would like to use Panax Ginseng 200 mg for anxiety and general boost of energy but I take Tadalafil 5 mg and need to take it for 3 months and can it interact with tadalafil?

Thanks a lot for your help.

    David Tomen
    October 5, 2022

    It shouldn’t be a problem. Ginseng has a completely different mechanism of action to Tadalafil.

      October 6, 2022

      David thanks a lot for your comment.

      I know they work in totally different ways, but I just wondered and asking you as I found the following studies about Ginseng and cytochrome P450 CYP3A possible interactions. Tadalafil’s metabolism: (predominantly CYP3A4)

      So please let me know your opinion if it might affect the efficacy of tadalafil.

      Of course, I can understand it’s not dangerous to take them together, but I still don’t want to take tadalafil if Ginseng diminishes its efficacy a lot.

        David Tomen
        October 7, 2022

        That is IF Tadalafil is metabolized by CYP 3A4 ( If is it not then you’re good.

        October 8, 2022

        Thanks a lot David sharing it.

        In the article you shared they talk mostly about (imatinib, raltegravir) but Tadalafil is metabolised by CYP 3A4 and do you think it can still interact with Ginseng? Can it be dose related?

        David Tomen
        October 9, 2022

        It’s like dose related but, and I may have this wrongs, I think Ginseng may reduce the efficacy of Tadalafil because of its effect on that enzyme. Correct if I am wrong.

August 23, 2022

I should be able to stack ginseng with cordyceps safely, correct?

    David Tomen
    August 31, 2022

    Matt, is shouldn’t be a problem. It certainly is not contraindicated.

June 18, 2022

HELLO DAVID! For Ed panax ginseng dosage is 900mg three times a day , so it 2700 mg in a day or 900 mg total in a day. Thanks

    David Tomen
    June 19, 2022

    Abdullah, I’m not sure what you are asking here or are you suggesting something. Dosage of Panax Ginseng varies and it often depends on the strength of the extract.

      Stephen Bonnell II
      November 10, 2022

      I believe Abdullah/M was asking if “For erectile dysfunction (ED): 900 mg of Panax ginseng 3-times per day” means 900mg total (300mg each in the morning, afternoon, and late afternoon), or 2700mg total (900mg each in the morning, afternoon, and late afternoon) which I am as well curious about. Thanks Dave

        David Tomen
        November 16, 2022

        Stephen, 900 mg of Panax ginseng 3-times per day means 900 mg in the morning, 900 mg at noon and another 900 mg later in the afternoon.
