Are Nootropics Safe? What to Know About Risks and Safe Use

Boosting your cognitive performance is never a bad thing, but some proposed routes to enhanced cognition are safer than others. Nootropics, or "smart drugs," are a class of substances that have gained popularity as a means to enhance memory, focus, creativity, and overall brain function. 

These substances encompass a wide range of compounds, from natural herbs to synthetic drugs. But there's one ever-burning question to consider before you dive into a smart drug regimen–are nootropics safe? 

There's no blanket answer, as every nootropic substance has its own unique benefits and drawbacks. Still, many nootropics, and especially natural nootropics, are considerably safe. Just like all supplements, nootropics come with various risks and side effects to be aware of. 

Below, we’ll dive into the depths of nootropics safety, featuring many of the most popular nootropic supplements on the market today. Here’s what you should know:

The term "nootropics" was coined in 1972 by Romanian psychologist and chemist Corneliu E. Giurgea, who defined them as substances that enhance learning and memory, protect the brain from injury, and exhibit minimal side effects. 

His first nootropic creation, Piracetam, was one of the first nootropic drugs found to have a positive impact on cognitive function without causing any sedation or stimulation. At the core, the idea behind nootropics is that they bring cognitive benefit without doing any harm, which is why many substances classified as a nootropic are inherently safe to use at recommended doses. 

However, that’s not to say that nootropics come without risk. Nootropics work through various mechanisms, such as increasing blood flow to the brain, boosting neurotransmitter levels, or protecting neurons from oxidative stress. 

Because they all work uniquely, there’s no accurate way to determine how different nootropics will affect you. Every person’s experience will be unique, and you need to account for specific risk factors, like drug interactions or potential allergic reactions, in addition to regular side effects. 

Before we break into the research surrounding nootropic safety, let’s take a look at some of the most popular synthetic and natural nootropics on the market and their individual benefits:

Many natural compounds have been labeled as nootropics due to their alleged cognitive-enhancing properties. Some well-known natural nootropics include:

• Bacopa Monnieri: Derived from a herb found in traditional Ayurvedic medicine, Bacopa Monnieri is believed to improve memory and reduce anxiety.
• Lion’s Mane Mushroom: Lion’s Mane mushroom is thought to improve memory and focus via several mechanisms. Most significantly, it’s thought to stimulate the growth of neural pathways in the brain to strengthen neural connections.
• Cordyceps Mushroom: Cordyceps is known to increase blood flow to the brain, which may increase processing speeds. Plus, it’s thought to provide a significant physical boost and is often described as the “athlete’s mushroom.”
• Ginkgo Biloba: This extract from the gingko tree is thought to enhance blood circulation in the brain, potentially benefiting memory and mental clarity.
• L-Theanine: L-theanine is an amino acid commonly derived from tea leaves that acts both as an adaptogen and a nootropic. Its calming effects are thought to pair with the tea’s natural caffeine in a way that promotes enhanced focus without anxiety or jitteriness.
• Alpha–GPC: Alpha-GPC is thought to enhance memory, and is actually approved as a treatment for some forms of dementia in some countries.
• Rhodiola Rosea: An adaptogenic herb that may alleviate stress and fatigue, leading to improved cognitive function.
• Panax Ginseng: Known for its potential to enhance mental alertness, memory, and overall cognitive performance.

On the other hand, synthetic nootropics are often pharmaceutical compounds that were initially developed to treat specific medical conditions but have shown cognitive-enhancing properties. Some of the most well-known synthetic nootropics include:
 

• Modafinil: Originally developed to treat narcolepsy, Modafinil is believed to promote wakefulness and improve focus.
• Piracetam: One of the earliest synthetic nootropics, Piracetam, has been associated with enhanced memory and learning abilities.
• Aniracetam: A derivative of Piracetam, Aniracetam, is thought to improve creativity and reduce anxiety.
• Phenylpiracetam: Known for its stimulant-like effects, Phenylpiracetam may enhance physical and mental performance.

When evaluating the safety of nootropics, several factors need to be considered:

One of the challenges in assessing the safety of nootropics is the lack of extensive human clinical trials for many of these substances. While some have undergone limited testing, others have not been subject to any rigorous testing at all. This, in addition to the unique differences in each nootropic substance's mode of action, makes it difficult to draw any finite conclusions about the safety of nootropics. 

Furthermore, many nootropic substances exist as dietary supplements, which means they are not regulated in the same manner as prescription drugs. Regulation also varies by country, and in most cases it is up to the consumer to evaluate the quality of a supplement for purchasing.  The lack of standardized regulations can lead to inconsistent quality control and safety oversight.

The response to nootropics can vary significantly from person to person. Factors such as genetics, metabolism, existing health conditions, and medication interactions can influence how an individual's body processes and responds to these substances. A nootropic that proves beneficial for one person may cause adverse effects in another. 

Additionally, a person’s health history and current medication routine also plays a role in nootropic safety, as some nootropics may have drug interactions. (We’ll cover this more below.)

While some natural nootropics have been used for centuries with minimal reported side effects, synthetic nootropics can carry a higher risk of adverse reactions. Common side effects reported with synthetic nootropics include headaches, gastrointestinal issues, insomnia, and anxiety, but we’ll cover more on specific safety issues for nootropic drugs below. 

Although rare, allergic reactions can occur with certain nootropics. If you have known allergies or sensitivities to specific substances, carefully review the ingredients of any nootropic product you consider using. 

Some individuals may be allergic to mushroom-derived nootropics like Cordyceps or Lion's Mane. If you experience any allergic symptoms such as skin rashes, itching, difficulty breathing, or swelling, discontinue use and seek medical attention immediately.

Another concern with nootropics, especially the synthetic variety, is the potential for dependency and tolerance building. Some individuals may experience diminishing effects with prolonged use, leading them to increase the dosage, which can further increase the safety risks.

Individuals taking prescription medications should be cautious when considering nootropics, as interactions between these substances and pharmaceutical drugs can be unpredictable and harmful. Nootropics that affect neurotransmitter levels or blood circulation may interfere with other medications, potentially leading to adverse outcomes.

For instance, some nootropics, such as Alpha GPC, may have interactions with anticholinergic drugs or medications for Alzheimer's disease. Caffeine, when combined with certain medications like stimulants or MAO inhibitors, may lead to adverse effects. Certain medicinal mushrooms should not be taken with antidepressants or blood thinning medications. 

To ensure your safety, you should always speak to your doctor about your plan to use nootropic supplements and discuss the possibility of drug interactions with any prescriptions or other supplements you are currently taking. 

Let's examine some of the most popular nootropics and explore their safety profiles based on available research:
 

• Bacopa Monnieri: Research on Bacopa Monnieri suggests that it is generally safe when taken within recommended dosages, both in single and chronic doses. Side effects may include mild gastrointestinal discomfort or nausea, which is typically temporary. However, further long-term studies are needed to understand potential effects on liver health and interactions with medications.
• Cordyceps: Cordyceps mushroom is generally well tolerated and is thought to be safe for those who do not have a mushroom allergy. However, because some mushroom supplements contain whole-mushroom compounds, they may be linked to mild digestive side effects for some people, like nausea or upset stomach. Cordyceps may also have some drug interactions with antidepressants or medications that affect circulation, blood pressure, or blood sugar. 
• Ginkgo Biloba: Ginkgo Biloba has been widely used and studied for its cognitive benefits. Short-term use appears to be safe for most individuals, with mild side effects such as headaches and gastrointestinal issues reported in some cases. 
  However, some reports show concern for its potential interaction with anticoagulant medications,  so it is important for those on anticoagulant drugs to consult with a healthcare professional before using Ginkgo Biloba.
• Modafinil: Modafinil is a prescription drug, and its safety profile has been extensively studied for its approved uses in treating narcolepsy and sleep disorders. Generally well-tolerated, common side effects include headaches, nausea, and insomnia. However, its long-term effects on the brain and potential for dependency are still areas of concern.
• Lion’s Mane: In general, Lion’s Mane’s safety profile is sound. Supplements are generally well-tolerated, and studies have noted that they are safe when doses of up to 750 milligrams are taken daily for up to 16 weeks. Some research even suggests that higher doses are well tolerated. 
  Evidence here is limited, however, and mushroom allergies should be a cause for caution. Plus, some mushroom supplements interact with blood thinners, antidepressants, and other medications, so always check with your doctor first. 
• Piracetam: Piracetam has been studied for several decades and is considered relatively safe when used within recommended dosages. Side effects are generally mild and may include headaches, dizziness, unsteadiness, and gastrointestinal discomfort. However, some concern for drug interactions involving anticoagulant medications. 

The use of nootropics to enhance cognitive performance is a topic that continues to spark interest and debate. Keep in mind that everyone's body chemistry is unique, and individuals may respond differently to various nootropics. As you start and follow through with your nootropic journey, you’ll want to pay close attention to how your body and mind react to the substances you are using.

Consider keeping a journal to track any changes in mood, sleep patterns, energy levels, or overall well-being. This self-monitoring approach can help you identify potential side effects and make adjustments accordingly.

While nootropics do have the potential to help enhance cognitive function, it is essential to be aware of potential side effects and take necessary precautions. Understanding the benefits, potential risks, proper dosage, and stacking guidelines will help you make informed decisions.

Be mindful of potential drug interactions and any allergic reactions you may have. Always talk to your doctor before starting nootropic supplements to ensure that they will not negatively react to your current wellness regimen.

As the field of nootropics continues to evolve, more extensive research and standardized regulations are needed to provide a clearer understanding of their safety and efficacy. Until then, the best approach is to focus on evidence-based lifestyle habits such as a balanced diet, regular exercise, sufficient sleep, and cognitive stimulation to support.
