Resveratrol is a potent antioxidant, boosts BDNF, increases cerebral circulation, improves energy and memory, and potentially promotes longevity

Resveratrol (3,4′,5-trihydroxy-trans-stilbene) is a polyphenol stilbenoid and phytoalexin that certain plants produce in response to stress, such as injury or fungal infection.Resveratrol is a nootopic found in red wine

Resveratrol is a naturally occurring compound found most famously in red wine. Some speculate that the Resveratrol found in red wine accounts for the “French Paradox”. And how the French can dine on baguettes, cheese, paté and pastries. While avoiding putting on weight and living longer.

Recent research may soon lead the nootropics community to classifying Resveratrol as an Ampakine nootropic. With some rather profound neuroprotective effects in the brain.

Resveratrol is gaining a reputation among neurohackers for controlling brain inflammation, boosting dopamine, helping reverse cognitive decline and fighting brain cell aging.

Resveratrol helps:

  • Brain-Derived Neurotrophic Factor (BDNF). Higher levels of BDNF are associated with increased intelligence, mood, productivity and memory. And decreased risks of neurodegenerative diseases like Alzheimer’s and Parkinson’s. Resveratrol increases BDNF in your hippocampus.
  • Neuroprotectant. Resveratrol protects your brain by boosting the production of the enzyme heme oxygenase which protects against oxidative stress.[i] Resveratrol shields mitochondria from injury during interruptions in blood flow such as a stroke.[ii] And Resveratrol prevents the release of toxic glutamate during a stroke.[iii] It even protected the brain when administered 6 hours after a stroke.[iv]
  • Cerebral Circulation. Resveratrol increases blood flow in your brain. Improving your brain’s blood flow increases oxygen and nutrient levels. Providing your brain with the fuel it needs for optimized cognition.

Overview

Resveratrol (3,4′,5-trihydroxy-trans-stilbene) is a naturally-derived polyphenol antioxidant. This phytoalexin helps plants fight fungal infection, insect infestation, stress and ultraviolet radiation. And we are finding that Resveratrol could be a potent nootropic.

Initial research on Resveratrol led researchers to believe that the compound works by mimicking calorie restriction and decreasing chronic inflammation.

As soon as word got out about the first clinical studies at Harvard Medical School, red wine and Resveratrol were soon christened the new “Fountain of Youth”.

But Dr. David Sinclair who led the Harvard study says, “You would need to drink a hundred to a thousand glasses of red wine to equal the doses that improve health in mice.”[v]

However, more research has revealed some rather profound benefits to adding Resveratrol to your nootropic stack.

Several human studies show that Resveratrol can increase cerebral circulation, protect against heart disease, and increase insulin sensitivity in diabetics.

Even more studies in animals have shown that Resveratrol can reduce depression, treat addictions, protect against memory loss, is anti-anxiety, reduces plaques in Alzheimer’s disease, improves learning, memory and mood, protects the brain from stroke and shields from hearing loss.

Resveratrol is found in red wine, blueberries, cranberries, raspberries, bilberries, grapes, peanuts, pistachios, cocoa and dark chocolate.[vi]

Here we’re going to dig into how Resveratrol helps your brain. Some of this is going to get a little geeky, so stay with me here…

Resveratrol increases Brain-Derived Neurotrophic Factor (BDNF)

How does Resveratrol work in the brain?

Resveratrol boosts brain health in several ways. But two in particular stand out.

  1. Resveratrol improves memory. Resveratrol is an inhibitor of enzyme PDE4 (Phosphodiesterase-4). PDE4 inhibitors have been shown to be memory enhancers.[vii] Studies demonstrate that when you inhibit PDE4, you raise levels of cAMP in the brain.[viii] cAMP-dependent pathways in the brain activate AMPK (AMP-activated protein kinase).[ix]

This effect of activating AMPK has a number of implications. First, this would make Resveratrol an Ampakine nootropic similar to some of the racetams.

Second, studies show that AMPK is activated by increases in the cellular AMP/ATP ratio. This helps preserve cellular energy. And would account for at least some of Resveratrol’s neuroprotective properties.[x]

This same study at the Washington University School of Medicine in St. Louis, Missouri demonstrated that Resveratrol combined with the nootropic ALCAR increased neurite growth which would have a profound effect on boosting memory. And Resveratrol also stimulated mitochondrial biogenesis.

The researchers concluded, “These findings suggest that neuronal activation of AMPK by Resveratrol could affect neuronal energy homeostasis and contribute to the neuroprotective effects of resveratrol.”

  1. Resveratrol boosts BDNF. Brain-derived neurotrophic factor (BDNF) has been called “Miracle-Gro for the brain” by Harvard Neuropsychiatrist John Ratey. When BDNF is released, nerve cells connect to other cells or their synapses. As brain cells “fire together”, they “wire together”. And this is how new neural networks are formed and consolidated to create memory.

Researchers in Iran administered Resveratrol to rats for 30-days. The team was looking at the effects of Resveratrol on the abundance of mRNA encoding Brain-Derived Neurotrophic Factor in the hippocampus.

The team measured levels of BDNF in the rat brains and found that Resveratrol elevated the level of BDNF in the hippocampus of these rats. And concluded that the neuroprotective effects of Resveratrol are due to its ability to boost BDNF mRNA.[xi]

How things go bad

As we get older, the chemistry in our brain cells and energy metabolism changes.

↓ Neurons and synapses degenerateResveratrol-boosts-cerebral-circulation

Recall, reaction time, memory, and mood diminish

↓ Cerebral circulation decreases

Neurotransmitter levels decline

↓ Oxidation damages brain cells

All of these age-related changes are contributing factors to the neurodegenerative diseases of aging including Alzheimer’s, Parkinson’s and dementia.

But even if things haven’t degenerated to such a debilitating level, Resveratrol can help.

Resveratrol benefits

Resveratrol is an antioxidant polyphenol which are present in foods like red wine, green tea, apples, berries, pomegranates and dark chocolate.

Polyphenols are among the most effective natural ways to combat aging. And to prevent the health issues that often lead to cardiovascular and neurodegenerative disease.

Resveratrol helps prevent free radical damage to brain cells. Oxidative damage to brain cell membranes causes deterioration. And eventually leads to premature cell death (apoptosis).

Resveratrol has the unique ability to modulate cell apoptosis. And promotes cell death only in instances where your brain would be healthier with fresh, new cells. Resveratrol promotes neurogenesis.

Resveratrol inhibits the PDE4 enzyme that raises levels of cAMP in your brain. Much like Luteolin (Artichoke Extract) in the CILTEP stack. cAMP-dependent pathways in the brain activate AMPK which in turn energize brain cells, and boost memory.

Resveratrol helps boost cerebral circulation, and Brain-Derived Neurotrophic Factor (BDNF). BDNF helps new neural networks to form which is the basis for memory formation.

How does Resveratrol feel?

Research shows that Resveratrol can:

  • Improve memory by inhibiting PDE4 in the brain (which boosts cAMP activity)
  • Tame inflammation in the brain
  • Boost cerebral blood flow for more oxygen and nutrients to fuel brain cells
  • Increase BDNF helping new neural networks to form for memory consolidation
  • Neuroprotective qualities that prevent damage to brain cells

Resveratrol quickly enters your brain after you take it. Once in your brain, it inhibits PDE4 which boosts cAMP activity. cAMP is involved in the Long-Term Potentiation process of preserving memories.

Inhibiting PDE4 and boosting cAMP also makes the effect of normal dopamine production more effective. Boosting processes in this stream of chemical reactions in the brain increases learning and memory. Without the side effects of stimulating dopamine production through the use of drugs like Adderall or Ritalin.

Neurohackers report the effects of Resveratrol can be subtle. But you don’t want to take it later in the afternoon or it could affect your sleep.

You may experience improved mood and motivation, increased ability to study, increased ability to retain information and improved long-term memory.

Resveratrol Clinical Research

As a young neurohacker, you may not be concerned about the horrors of a disease like Alzheimer’s. Yet several clinical studies make the case for using Resveratrol to boost your memory. And to avoid ever having to be concerned about this debilitating disease.

84,767 Americans die every year from Alzheimer’s disease. And more than 230,000 suffer from dementia severe enough to require nursing home care.[xii]

The Alzheimer’s Association estimates that more than 5 million Americans are living with this disease. And you have a 1 in 3 chance of developing Alzheimer’s or another dementia in your lifetime.[xiii]

Now that I have your attention, let’s look at some clinical studies on using Resveratrol to prevent Alzheimer’s and dementia.

Resveratrol Protects Against Alzheimer’s

Some of Resveratrol’s neuroprotective ability comes from its ability to interfere with the cascade of events arising from an accumulation of abnormal proteins called amyloid-beta.

Amyloid-beta causes oxidative stress and inflammation that damages brain cells. Especially in memory centers in the brain. Hence the reason why Alzheimer’s causes such profound memory loss.

A study conducted at the Litwin-Zucker Research Center for the Study of Alzheimer’s Disease in New York looked at the cascade of events leading up to Amyloid-beta accumulation that causes much of the problem with Alzheimer’s.

The research team demonstrated how Resveratrol activates several metabolic sensors, including AMPK (AMP-activated protein kinase). AMPK signaling controls Amyloid-beta metabolism. So Resveratrol activates AMPK which reduces levels of Amyloid-beta deposits in the cerebral cortex.[xiv]

Another study in Italy showed how Resveratrol prevents β-amyloid aggregation by scavenging oxygen free radicals, and inducing protective enzymes such as heme oxygenase. Again preventing the build-up of deposits causing Alzheimer’s.[xv]

More recent studies show that Resveratrol can prevent Amyloid-beta proteins from clumping together into small collections of individual molecules called oligomers. This action alone has a profound effect on preventing Amyloid-beta damage and preventing Alzheimer’s.[xvi]

And one more study, again about Resveratrol’s ability to activate AMPK and reduce Amyloid-beta build-up, shows that Resveratrol crosses the blood-brain barrier. And stays in the brain to do its magic. Verifying that using Resveratrol as a nootropic is an effective cognitive enhancer.[xvii]

Resveratrol Improves Memory

The research team at the Max Planck Institute for Human Cognitive and Brain Sciences investigated the effect of Resveratrol on brain function and memory in healthy overweight older adults.

23 people, aged 50 – 75, took 200 mg of Resveratrol daily for 26 weeks. The control group of 23 subjects took a placebo. Memory tasks, neuroimaging, microstructure and functional connectivity of the hippocampus were measured before and after the trial.

The study found that Resveratrol had a significant impact on subject’s ability to remember words. Subjects had a significant increase in functional connectivity in the hippocampus. And there was a decline in glycated hemoglobin (HbA1c), which indicates improved blood sugar control.

The researchers concluded that Resveratrol can enhance memory along better hippocampus function.[xviii]

Resveratrol Improves Cerebral Circulation

A study conducted at Northumbria University at Newcastle upon Tyne in the UK assessed the effects of Resveratrol on cognition and cerebral blood flow in healthy adults.

In this double-blind, placebo-controlled study, 22 healthy adults received a placebo and 2 doses (250 and 500 mg) of trans-Resveratrol in counterbalanced order on separate days.

The subjects performed a selection of cognitive tasks that activate the frontal cortex 45-minutes after taking Resveratrol. Near-infrared spectroscopy assessed frontal cortex changes in oxygenated and deoxygenated hemoglobin in order to evaluate blood flow and hemodynamics during the 36 minutes of task performance.

The research team found that Resveratrol increased cerebral circulation. And this effect was entirely dependent on the size of the dose of Resveratrol. Blood flow was determined by measuring total hemoglobin concentrations.

The researchers concluded that Resveratrol can increase cerebral blood flow even with a single dose of the supplement.[xix]

Resveratrol Recommended Dosage

Resveratrol is found in small quantities in red wine, and some plant foods. Red wine contains about 1.5 – 3 mg of Resveratrol per liter of wine. So if you do the math, comparable amounts of Resveratrol from red wine for a 150 lb. person means 750 – 1,500 bottles of red wine a day.Resveratrol-nootropic-dosage

Resveratrol has a considerably shorter half-life than its cousin Pterostilbene. And is easily absorbed but has poor bioavailability once digested.[xx] It’s half-life is 1 – 3 hours, and 2 – 5 hours following repeated dosing.[xxi]

Micronized Resveratrol, which has a much smaller particulate size, has been shown to have a 3.6-fold increase in bioavailability compared to standard Resveratrol.[xxii]

And many of the clinical studies done in animals suggest a human equivalent of 1 -2 grams for a 150 – 200 lb. person. Many supplement makers offer much smaller quantities in capsules or tablets. (I do not advise taking such high doses of Resveratrol).

But even in small amounts, Resveratrol is believed to provide some of the benefits talked about in this article.

Based on all of the published studies, the recommended daily dose of Resveratrol is 20 mg for heart health, insulin sensitivity and longevity. For cognitive benefit, and increasing cerebral blood flow, recommended dose is 250 – 500 mg of Resveratrol.

It’s better to dose on the lower end of recommended doses of Resveratrol. And see how your body reacts.

Resveratrol Side Effects

Resveratrol is non-toxic and supplementation is well-tolerated by most people. We do not have many human studies on Resveratrol and must rely on user reviews.

Resveratrol has mild estrogenic activity in the body. So if you’re estrogen is low you should avoid supplementing with Resveratrol. This is a potentially serious side effect. And short of getting your labs done, it may show up as joint pain or arthritis-like symptoms.

Some neurohackers report having trouble sleeping, or staying asleep. Particularly if taken in the afternoon or evening.

If you are dealing with a blood disorder which causes bleeding you should avoid Resveratrol. If you are taking aspirin, warfarin or clopidogrel you should not use Resveratrol.

Long term side effects reported by some neurohackers include diarrhea, discolored urine, dizziness, insomnia, jitters, joint pain, stomach pain and tendinitis.

Type of Resveratrol to Buy

Resveratrol comes in tablet, capsule or powder form and is available by several well-known supplement makers.

Most Resveratrol supplements are made from Japanese Knotweed. And some from grape skin extract.Resveratrol for brain-fog

The bioactive form used in clinical studies and found in supplements is ‘Trans-Resveratrol’. ‘Cis-Resveratrol’ is a cis isomer and still bioactive but has a very different chemical structure.

Purity of Resveratrol is extremely important. Most Resveratrol is made from Japanese Knotweed. A poor quality extract can contain high amounts of Emodin which can act as a laxative and cause stomach cramps.

High purity Resveratrol extract (99%+) from Japanese Knotweed contains insignificant amounts of Emodin. And should cause far fewer side effects.

Your safest bet when choosing a Resveratrol supplement is an extract from grapes or red wine which contain no impurities. And ideally the ‘micronized’ version of Resveratrol.

Nootropics Expert Recommendation

Resveratrol 20 – 250 mg per pay

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

Your body does not make Resveratrol on its own. You can get some Resveratrol from red wine and a few other fruits. But studies have shown we may not get an adequate supply of Resveratrol from food sources in our diet. Especially if you don’t eat a lot of fruit containing Resveratrol every day. Or don’t drink red wine.

I recommend choosing a Resveratrol supplement that is either 99% pure from Japanese Knotweed. Or a pure extract from grapes or red wine. Ideally the ‘micronized’ version of Resveratrol.

Resveratrol is unique among antioxidants because it easily crosses the blood-brain barrier. And helps protect your brain from free radical damage.

Resveratrol helps improve memory by influencing the cAMP-dependent pathways in your brain that activate AMPK.

And Resveratrol boosts cerebral blood flow which increases the amount of oxygen and nutrients your brain cells need for optimized cognition.

Resveratrol is especially helpful for those concerned about developing Alzheimer’s or dementia. Because it helps prevent the accumulation of abnormal proteins like amyloid-beta.

We suggest starting with a dose of at least 20 mg daily. And Resveratrol is a great compliment to a stack including any nootropic. One study showed Resveratrol worked synergistically with ALCAR to boost memory.

And Resveratrol works particularly well when combined with Pterostilbene.

Hi David, I had been doing some research recently on microglia and depression and anxiety. Resveratrol kept coming up as the best supplement to help with brain inflammation and depression and anxiety. I have either taken one 200 mg dose with breakfast or added a second dose with lunch. Don’t think I’ve seen any negative sleep issues (I have had insomnia for 3 years and 8 months, but who’s counting!).

Do you think it will help with depression and anxiety. I had read that Pterostilbene is a better option. I noticed on this page you suggest taking both? If so, both at breakfast is probably the safest option?

I am trying to see if dealing/healing brain inflammation will be an answer for the lifelong depression and anxiety.

Lastly, I have seen some research claiming resveratrol actually helps with sleep issues. Have you seen this?

    David Tomen
    June 16, 2023

    Gary, there is plenty of research showing depression can be caused by low BDNF or inflammation. Both supplements help increase BDNF and decrease inflammation. One is not ‘better” than the other. Is suggest trying each separately for a month as your own little clinical trial and see how you feel.

Hi David. Could you maybe help to clarify some of the issues regarding Resveratrol dosage and its possible link to cancer? Over the past 18 months or so there seems to have been an ‘anti-Dr David Sinclair’ movement. There are murmurs in the scientific community that low doses might actually protect cancer cells (as an antioxidant), and higher doses might be safer as they may initiate apoptosis. On the other hand, there are other studies suggesting that higher doses create too much of a pro-oxidant effect and the hormetic benefits are lost (the overload pushes past NRF2 activation and leads to an increase in NFkB). Some of these pro-oxidant effects can apparently be ameliorated by simultaneously taking anti-oxidants (e.g. melatonin/astaxanthin). However, I am concerned that this might simply blunt any positive hormetic effect (??) if you can get the dosages right. It just seems very convoluted. It’s already a delicate process as I stack Resveratrol with quercetin (increased bioavailability), NR or NMN to boost NAD+ and then activate AMPK in other various ways (apple cider vinegar, berberine, fasting etc.) – all in order to maximize its ‘anti-aging’ potential.
Kindly note that I am paraphrasing the work of other people, but have you heard anything about this, and if so what are your opinions? Should we be concerned? Thanks as always. Be well

    David Tomen
    November 7, 2022

    Giovani, more is never better with nootropics. It’s why I always recommend a low and maximum daily dose. Some nootropics, especially those that work as antioxidants, become prooxidants when they are over dosed. Just one of the reasons why more is not better.
