What Is Piracetam?
Piracetam is among the very first nootropic smart drugs. Its discovery dates all the way back to 1964. Research was led by Dr. Corneliu E. Girugrea and upon his discovery of Piracetam, he coined the term nootropic to describe its properties.
Piracetam was launched clinically in the early 1970′s under the name Nootropil and is currently used in many European countries. Since the invention of Piracetam, other pharmaceutical companies began their own research.
An entire family of ‘racetam drugs has since been born. Some nootropics in the ‘racetam category include aniracetam, oxiracetam, pramiracetam, and nefiracetam. Though all the ‘racetam drugs have somewhat similar mechanisms of action, others are much more potent. Piracetam is regarded as the least potent of the family.
Cognitive Benefits of Piracetam
Research has shown piracetam to provide a wide array of positive mental benefits, below are the ones with the most substantial backing evidence.
- Piracetam has been shown to improve memory in healthy individuals. One double blind study found a significant improvement in verbal learning after two weeks of treatment.
- Research suggests Piracetam can reverse the effects of aging on the brain and help prevent cognitive disorders.
- Piracetam has been shown in animal studies to improve communication between the left and right hemispheres of the brain and to increase the amount of activity in the corpus callosum.  The corpus callosum is a bundle of neural fibers which connects the left and right parts of the brain. Studies have suggested that increased communication between brain hemispheres results in improved memory, learning, and recall. 
- Piracetam increases mental energy (ATP), particularly when levels are low. One study showed that Piracetam boosted levels of brain glucose metabolism in rats by 22%. This is noteworthy because brain cells produce their own ATP from glucose and oxygen. An increase in the metabolism of glucose within the brain translates to higher levels of ATP.  Studies have also shown that it increases the rate of synthesis of cytochrome b5, which is an integral part of the electron transprot chain. 
- Piracetam improves synaptic plasticity, which is the ability of the brain to create new synapses between brain cells and to strengthen existing ones. Increased plasticity increases the mental benefit gained from performing mental exercises and brain training games. (Such as the ones found at Lumosity)
- Piracetam increases blood flow to the brain and supplies it with more oxygen.  Oxygen is an essential fuel for our brains, which use close to 20% of our body’s entire oxygen supply. The brain devotes available oxygen to essential processes first and higher mental functions such as cognition last. Increasing your brain’s oxygen supply will positively affect all aspects of mental performance.
- Piracetam is neuroprotective, and has been shown to protect against and improve recovery from hypoxia, cerebral trauma, and damage caused by alcohol abuse.  One study showed that it was extremely effective in preventing cognitive damage due to surgical procedures.  Another study showed that acute piracetam treatment can protect against and treat ischemic brain damage. 
- Considerable anecdotal evidence suggests that piracetam has a positive effect on verbal fluency. Many users report an easier flow of conversations as well as an improved vocabulary when speaking. A study in which Piracetam improved language skills in dyslexic youth seems to back up this assertion , however we are not aware of any studies testing this claim performed on healthy individuals.
- Piracetam may improve the ability to drive. One study performed on elderly drivers in actual traffic observed an average improvement on a test of driving performance by ~7%. Test subjects who had scored under an 80% in the first test improved without exception after being administered piracetam. 
Medical Uses of Piracetam
- Piracetam is widely used throughout Europe, Asia, and South America as a prescription medication. It is most commonly used to treat a wide variety of mental illnesses such as Alzheimer’s, senile dementia, depression, anxiety, schizophrenia, and cerebral trauma.  It should be noted that there is still some debate as to the efficacy of Piracetam in treating these disorders. 
- A few studies have suggested that while Piracetam may not be very effective at treating Schizophrenia alone, it can improve the cognition in people suffering from it at least as much as it can in the healthy.  Interestingly a study has shown that a combination of piracetam and haloperidol is significantly more effective than a treatment of haloperidol alone.  The researchers speculate that glutamate receptors play a role is the physiology of schizophrenia, and that Piracetam improves the efficacy of haloperidol by acting as a positive glutamate receptor modulator.
- Studies have shown that Piracetam may be of some use as an anti-aging drug. Studies on mice have shown that it may reverse the effects of aging in the brain. Further studies have shown it to reduce levels of lipofuscin in the brain.  (Lipofuscin is formed by oxidation of unsaturated fatty acids and commonly accumulates due to aging or alcoholism.)
- Research has shown that Piracetam is an effective treatment for cognitive impairment caused by alcoholism.  It also may be useful in treating alcohol withdrawal related psycosis, though there is little evidence that it can make an alcohol addiction easier to quit. One study did find that it was at least as effective as chlormethiazole at mitigating withdrawal symptoms, however. 
- Piracetam has enjoyed a long history of use as a treatment for clotting and vasopastic disorders.  It does this by preventing the build-up of platelets and improving the malleability of blood-cells. Because this is a relatively novel mechanism of action, it works particularly well when combined with typical anti-thrombotic drugs.
- Some studies have suggested that Piracetam can successfully treat mild depression and anxiety.
- Piracetam’s neuroprotective effects can be seen in it’s ability to produce significant improvements in cognitive function in patients who suffered cerebral trauma. Treatments up to five years after the trauma occured have been shown to produce improvements in memory, focus, and motor functions. 
- Piracetam has been used to treat vertigo and dizziness resulting from head injuries. 
Many people who are new to nootropics take piracetam and expect to immediately feel smarter. When they take it for a few days and don’t feel any different they often get frustrated and stop. What they fail to realize is that piracetam is most effective not immediately after a single use, but after daily use for a period of at least two weeks.  This period of time is different for everyone: some people report it working within a week, others only after three weeks of continuous use. Take it daily for at least 3 weeks before trying to gauge if it’s working for you.
Piracetam can be taken either with food or on an empty stomach, although it is recommended to take it after eating. Staying hydrated while taking piracetam is also important.
It is also recommended that you take a choline supplement along with piracetam. This is for two reasons:
- Piracetam use causes the brain to deplete reserves of the neurotransmitter acetylcholine at a faster rate than normal. This is what causes the mild headaches that are sometimes a side effect of piracetam use. Choline is the precursor to the neurotransmitter acetylcholine, so taking choline supplements will allow your body to replentish it’s acetylcholine reserves at a faster rate.
- Piracetam has been shown to have synergy with choline.  This means that taking a choline supplement along with piracetam will cause it to be more effective than it would be otherwise.
Powder vs. Capsules
If you would like to start taking Piracetam, you have two basic ways to take it; either in capsules or in a bulk powder form. Bulk powder Piracetam is generally cheaper, but less convenient. Most people don’t like the taste of Piracetam powder, however it dissolves is water and the taste is hidden well by just about any type of flavored beverages. In addition with the purchase of a capping machine, the powder can easily be packed into homemade capsules.
How much cheaper is Piracetam in bulk powder as opposed to capsules? On Amazon.com we can see that 500 grams of bulk powder Piracetam costs $29.95 while only 48 grams of Piracetam capsules costs $23.44. This means that Piracetam powder costs $0.06 per gram while capsules cost $0.48 per gram.
Bottom line? Unless you are willing to pay a large premium for convenience, bulk powder Piracetam is a much better deal.
Piracetam’s safety and low side effect profile make it an extremely easy nootropic to experiement with. Don’t fall into the trap of thinking that the more you take the more significant your benefits will be. In fact, piracetam’s effectiveness can be mapped as a bell curve, with a specific optimal dose that will provide the greatest effects. This sweet spot is different for everyone and you will probably have to play around with your dosage until you find it. There are some guidelines that can help point you in the right direction, however.
Piracetam has a half-life of about 7.8 hours, with a plasma half-life of 5 hours. If you do not redose, it will completely clear from your body in about 30 hours.
Nootropic communities generally recommend that beginners take a dose of .8 to 1.6 grams taken two or three times a day. If you’ve never tried piracetam before this can be a good place to start. One recent study suggests that the optimal dose may actually be much higher, however. In this study, a single dose of either 2.9G, 4.8G, 9.6G, or a placebo were given to volunteers. Different measures of cognitive function where then measured using EEG potential maps. The study found that the cognitive measures were highest after the 4.8G dose.  This provides some direct evidence that taking too much piracetam can be counterproductive. It also suggests that the optimal dose of piracetam may be higher than what is usually reccommended.
The above dosage advice is for those who are taking piracetam for general cognitive improvement. Various studies have suggested other doses when using piracetam
for different reasons:
- When used to treat clotting or coagulation, a daily dose of 4.8 to 9.6 grams divided into three treatments per day 8 hours apart has been shown to be optimal. (When combined with a usual Warfarin or Heparin regimen) 
- When used to treat closed craniocerebral trauma, one study found a daily dose of between 1.6 – 2.4 grams to be effective. 
- When combined with haloperiodal, a dose of 3.2 grams per day proved much more effective at treating schizophrenia than a treatment of only haloperidol.
- One study found a significant improvement in verbal learning in healthy adults at a dose of 1.6 grams per day.

How Does Piracetam Work?
We still don’t completely understand the pharmacology behind how piracetam works, though we know that it has an influence on mental and vascular functions but that it doesn’t act as a stimulant or sedative. Research has shown that piracetam does the following, however:
- Piracetam is a positive allosteric modulator, meaning it regulates certain enzymes and proteins by binding to an effector. In this case, piracetam binds to the AMPA receptor, and in doing so increases its activity.  It then acts on ion channels or ion carriers to increase neuron excitability. This also explains its low toxicity and lack of inhibitory effects.
- Studies have shown that piracetam can help restore membrane fluidity of damaged neurons. This allows neurotransmitters to cross the membrane more easily and could explain piracetam’s neuroprotective properties. 
- It has been found to increase oxygen consumption in certain parts of the brain.
- Piracetam also increases the functionality of the neurotransmitter acetylcholine via ACh receptors. The neurotransmitter acetylcholine plays an important role in many mental processes including memory, synaptic plasticity, attention, and decision making. This effect could explain many of piracetam’s cognitive enhancing properties, as well as its effect on synaptic plasticity. This also explains why people taking piracetam use up choline at an abnormally fast rate. Taking choline with piracetam produces a synergistic effect since piracetam now has more fuel to carry out some of its functions. 
- Piracetam also has an effect on NMDA glutamate receptors. These receptors have heavily involved in mental processes related to learning and memory. 
- It appears to increase the rate of synthesis of cytochrome b5, as well as increasing mitochrondrial permiability in certain stages of the Krebs Cycle.  This is likely the cause of piracetam’s ATP increasing effect.
- It is thought to increase cell membrane permeability. 
Safety and Side Effects of Piracetam
Adverse Side Effects:
Piracetam is extremely safe and well tolerated in even high doses.  One large trial of high-dose piracetam found no adverse side effects in the group using piracetam when compared to the control group.  Countless other studies have reported similar findings.
Some side effects that have been reported include anxiety, insomnia, irritability, and mild headaches. Headaches associated with large doses are caused by the brain expending acetylcholine at a faster rate than usual, and can be allieviated by taking a choline supplement or a drug with cholinergic effects. (Such as Centrophenoxine)
Reactions With Other Medications:
I have been unable to find any evidence of dangerous interactions between piracetam and other medications. There is some speculation that taking piracetam in combination with stimulants such as Amphetamines can cause excitotoxicity, however there doesn’t seem to be any definitive proof one way or another. You should still consult with your physician before taking piracetam with other mediciations, just to be safe.
Anecdotal evidence suggests that piracetam may potentiate certain common drugs such as Caffeine, Alcohol, and THC. On the other hand, some people have reported the opposite. If combining piracetam with these drugs it’s best to start slow to see if piracetam will potentiate them for you or not.
There is considerable evidence that piracetam does potentiate MDMA, and can be effective at preventing MDMA related brain damage. 
Risk of Overdose:
Piracetam is so non-toxic it may actually be impossible to overdose on it. Acute toxicity studies were performed in an effort to determine piracetam’s LD50 (the dose which is lethal to 50% of test subjects) in various animals. When given to rats at a dosage of 8 grams per kg of bodyweight it failed to reach an LD50. Similar results were performed in other animals, with the same result. If extrapolated to humans this means that a 154 pound person could take 700 grams of piracetam at once without jeapordizing their life. Of course, doing this would be very stupid, and would probably cause negative side effects far exceeding what can usually be expected.
I have been unable to find any evidence suggesting that a tolerance forms to piracetam. In fact, because piracetam works best after prolonged periods of daily use it would be very surprising if a tolerance did develop. While some people claim they have developed a tolerance to it, it seems more likely that their brains have just adjusted to operating at a higher cognitive level causing them to feel normal despite still recieving cognitive benefits from the piracetam. If any of these reports were backed up with some quantitative measures of mental performance I would find them much more credible.
Addiction and Withdrawal:
There is no risk of developing an addiction to piracetam. It doesn’t cause a release of dopamine as most addictive drugs do, and produces no high. Withdrawal symptoms are very rarely reported, and tend to be mild. Anxiety and hand tremors are the most commonly reported withdrawal symptoms. The most frustrating part of ceasing a piracetam regimen is “feeling dumb” as its cognitive enhancing effects wear off and the brain’s functioning returns to baseline.
Legality and Availability
Information in this section may be outdated, don’t use us as a source of legal advice.
US / Canada:
Piracetam is legal to possess without a prescription in the US. For many years piracetam was marketed and sold as a nutritional supplement, and vendors were mostly left alone by the FDA. More recently, however, the FDA has sent warning letters to many manufacturers preventing them from selling it as a dietary supplement. Despite many claims of a ban on piracetam, many manufacturers have continued to sell it by not marketing it as a dietary supplement. There has been speculation that the FDA crackdown is in preparation for a play by US pharmecutical companies to gain exclusive rights to sell piracetam, though there hasn’t yet been much evidence to back up these claims.
In Canada it doesn’t seem to be available locally but can be delievered by international mail.
Piracetam is legal to possess without a prescription in at least the United Kingdom, Belgium, France, the Ukraine, and the Czech Republic. It is uncontrolled but requires a prescription to purchase in Finland, Italy, Norway, The Netherlands, and Poland. It is illegal to import Piracetam to Finland without prior approval.
Below are some of the most commonly asked questions about Piracetam. If you have a question that’s not on this list, send it to us at email@example.com and we will answer it for you.
Piracetam is one of the oldest, most time tested, and most reliable nootropics available. Anyone can benefit from its use, though it is often recommended for beginners.
I have never taken a nootropic before. Where should I start?
Piracetam has gained a reputation for being the beginner’s drug when it comes to nootropics. Many of its effects, such as improving cerebral blood flow, benefit all areas of cognitive function. Also, because people have been taking it for over 40 years, there’s a wealth of information available to use as research. If you are a beginner, I recommend you read our Beginner Nootropic Regimen.
Do you want to keep your brain healthy and lower your chances of getting Alzheimer’s?
You wont have to look much further than Piracetam. When combined with Choline and Uridine, you have an excellent mental health and general cognition regimen. All these nootropics revolve around the neurotransmitter Acetylcholine (ACh). They work synergistically to keep levels of ACh at a healthy level.
The Cholinergenic Hypothesis proposes that Alzheimer’s disease is in part caused by low levels of and poorly functioning ACh neurotransmitters. Currently, 10% of people over the age of 65 suffer from Alzheimer’s. Those aren’t chances that I am winning to take. No one knows the exact chance of getting Alzheimer’s if you take piracetam, but the fact remains. Taking piracetam will lower your chances of suffering from Alzheimer’s
This is completely dependent on the person. Some people report feeling effects after their first use while other people take piracetam for weeks before feeling an effect. If you don’t feel any different after one month it is best to abandon piracetam and try a different nootropic.
Nootropics such as aniracetam, oxiracetam, and pramiracetam are more likely to produce noticeable effects according to anecdotal evidence. If piracetam isn’t working due to poorly functioning adrenals, you should find a substitute outside of the racetam family.
Many people also take uridine because it has a synergistic relationship with choline. Taking these two supplements together can increase your brain’s synthesis of phosphatidylcholine(PC) by up to 45%.This layer of PC is critical for your cells ability to function properly. When choline levels in your brain are at low levels, your brain begins to take from this PC layer. Uridine is also converted to CDP-Choline in your brain supplementing the piracetam even more.
Taking two racetam nootropics, such as aniracetam along with piracetam may also produce a synergistic effect. Because piracetam and oxiracetam are water-soluble, while aniracetam and pramiracetam are fat-soluble, mixing a water-soluble racetam with a fat soluble racetam may produce synergistic effects.
Studies have shown that piracetam increase blood flow to the brain and communication between the brain’s left and right hemisphere. There are no such studies showing that any other racetam drugs perform these functions.
Piracetam is also regarded as the least potent of the racetam family. By this I mean two things:
- People experience more noticeable effects while taking aniracetam, oxiracetam, or pramiracetam when compared to piracetam. As I have said, it can take weeks for people to experience results when taking piracetam, most people get results the first time they take a different racetam.
- The recommended dosage for piracetam is much higher when compared to the other racetam drugs. This implies piracetam is not as potent. In other words, you need more to accomplish the same results.
Many people take a ratio of 2:1 with regards to piracetam : choline. This means if you are taking three 800mg doses of piracetam, you should take 3 400mg doses of choline. You don’t have to take these doses at the exact same time. It is fine to take three doses of piracetam and one, large dose of choline at the beginning of the day. Other people have suggested a 3:1 ratio or a 1:1 ratio. If you are getting headaches at a 2:1 ratio you may want to upgrade to a 1:1 ratio. If you already get lots of choline in your diet (more then 800-100mgs), you may want to downgrade to a 3:1 ratio.
Recently, a link has been discovered that links many piracetam non-responders together. A study conducted on rats revealed that when their adrenal glands were removed, the piracetam had no effect. This means that people with improperly working adrenal glands likely won’t get much benefit from piracetam.
The most common condition piracetam non-responders suffer from is called adrenal fatigue. Adrenal fatigue occurs when someone’s adrenal glands function below normal levels. Some symptoms associated with this condition include:
- Feeling tired even after getting an adequate level of sleep
- Finding it extremely difficult to get out of bed in the morning
- Having more energy late in the day (after 5pm) then you did the rest of the day
- Constantly craving sweets
Luckily, there is a simple test you can perform on yourself to determine if your adrenal gland is functioning properly.
- Get a flashlight.
- Stand near a mirror in a closed room with no lights on. Complete darkness is required.
- Shine the flashlight on your eyes from the side, not directly into them.
- Your pupils should become smaller.
- Over the next 90 seconds, take note as to whether your pupils remain small or fluctuate in size.
If you have healthy adrenals, your pupils should remain small. If you have adrenal efficiency, your pupils will get small but will begin to fluctuate after 30 seconds.
So what can you do if you suffer from poorly functioning adrenal glands? Studies have shown that corticosteroid supplementation along with aldosterone will allow piracetam to function properly. You can purchase these supplements here. People have also reported pregnenolone has helped them. Pregnenolone is a supplement that is eventually turned to aldosterone by your body. Fludrocortisone (Florinef) makes for an excellent corticosterone replacement.
Constantly being sleep deprived and suffering from chronic stress can cause your adrenal glands to function below normal levels. If you feel as though piracetam is losing its effect, perform the eye pupil test to determine if your adrenal glands are being affected.
If you do not want to use those additional supplements, it is best to look for a nootropic outside of the racetam family.
Anecdotal evidence has mixed results. Some people say that taking piracetam allows them to drink more alcohol while other say they get intoxicated at a faster rate. However, most people say the hangovers the next day are much worse when taking piracetam. To be completely safe, it is best not to consume piracetam and alcohol together.
The best way to track you progress is through brain games. At Lumosity you can find games to test memory, attention, problem solving, and mental speed. Playing these games once a week and recording the results is a great way to track your progress. Especially if you aren’t feeling a very noticeable effect.
Playing these types of games regularly can actually improve your cognitive abilities as well. Combining the use of nootropics with brain games can produce an even greater effect just taking nootropics alone.
If you can’t take a racetam nootropic due to adrenal problems, a caffeine,L-Theanine combination has shown to be very effective at improving cognitive abilities.
