Best Keto Nootropics – A Buyer’s Guide

Share to save for later!

If you’d like to enhance your focus, boost attention span, slash anxiety, and improve your cognitive abilities, then nootropics may be the answer. In this unbiased and evidence-based article, you’ll learn exactly what nootropics are, and how to use them for optimal results. So, keep reading!

​Nootropics: What Are They and Why Should You Care?

A nootropic is a compound – either artificial or natural – that can enhance cognitive functioning. How it improves cognitive abilities depends on the nootropic, but common ways are increased focus, improved energy levels and memory, and decreased anxiety.

Usually, nootropics work by increasing or decreasing certain neurotransmitters (brain chemicals), modulating neuronal metabolism, improving blood flow to the brain, raising neurotrophic factors, or by influencing other cellular processes.

Now, there's one important thing to note: nootropics are NOT a magic pill that will instantly turn you into a genius, like in the movie Limitless. Instead, they can give you a small edge in unlocking peak mental performance, so that you can study better for your exams, boost your productivity at work, or feel more at ease during social gatherings.

Are Nootropics Safe?

Since nootropics are relatively new, most of them lack long-term research. That’s why the long-term effects of cognitive-enhancing drugs are mostly unknown, and why the safety of taking them long-term can’t be guaranteed.

This uncertainty is even greater among children and young adults because the brain doesn’t fully mature until around the age of twenty-five (1).


That’s why this age group is better off by optimizing brain functioning through focusing on getting enough sleep, maintaining a healthy diet, and following a proper exercise plan.

That said, nootropics are generally believed to be safe, and some of them even have protective or health-promoting qualities for your brain and body.

What to Look for When Buying Keto-Friendly Nootropics

As with every supplement, the quality among nootropic products varies tremendously. That’s why, to benefit from nootropics and support your health and well-being, it’s crucial that you select the right product. Here are four important factors to look for when buying nootropics.

  • Proper active ingredient. Many manufacturers use cheap ingredients to raise their profits. But if you want to experience the maximum benefits, it’s crucial that the active ingredient is present in the right form.
  • Adequate quantity. Once you’re sure that the product contains the active ingredient in the right form, check if it’s present in the right dosage, because no matter how potent an ingredient is, if it’s not available in the right amount, it’s still ineffective.
  • Certificate of Analysis (CoA).  Choose a product that has a CoA, which means that it’s independently lab-tested to ensure quality, potency and that it doesn’t possess any potentially harmful compounds. A few popular third-party testing companies include US Pharmacopeia (USP Verified) and Consumer Lab.
  • Junk-free. Many products are loaded with compounds that are not keto-friendly, such as yeast, soy, preservatives, fillers, added sugar, or artificial flavorings or colorings, and so forth. Choose a product that doesn’t contain these compounds.

Bacopa Monnieri

Bacopa Monnieri is a well-researched Ayurvedic herb that’s best known for enhancing memory​, concentration and increasing ​neuroprotection, according to many studies (2, 3, 4, 5, 6, 7, 8, 9, 10, 11).

One systematic review of six randomized and controlled studies, for example, found that supplementing with between 300 and 450 mg of Bacopa Monnieri extract a day significantly enhanced memory in older adults (12).

While it’s unclear how exactly Bacopa enhances memory, it’s believed there are three main reasons why it does so; because it’s a potent anti-oxidant; because it stimulates blood flow to the brain; and because it functions as a weak acetylcholinesterase inhibitor.

Recommended product: The ​Bacopa ​Powder by Lost Empire Herbs.


  • Very potent, as it contains 15% bacosides (meaning it has plenty of saponins such as bacopasides, brahmine, and monnierasides)

  • Contains no GMO's, preservatives, fillers, added sugar, or artificial flavors or colors

Ginkgo Biloba

Ginkgo biloba is a popular brain booster that’s derived from the Ginkgo biloba tree.

Research shows that it can increase focus and memory, which it does primarily by enhancing the blood flow to your brain (13).

Ginkgo biloba is also found to reduce age-related cognitive decline (14). 

​Research shows that taking it before a taxing task helps you cope with the situation by reducing stress-related high blood pressure, decreasing levels of the stress hormone cortisol, and impairing anxious feelings (15).  

Recommended product: BulkSupplements ​Pure ​Ginkgo ​Biloba ​Leaf ​Extract ​Powder.


  • Clean and pure gingko biloba powder

​L-theanine + Caffeine

If you want to enhance focus and attention span, supplementing caffeine along with l-theanine (a compound that’s found primarily in tea) is one of the most reliable, cost-efficient, and safe nootropic stacks.

The reason is that this stack works synergistically (16).

For example, research shows that the combination of L-theanine and caffeine improves the attention span more than caffeine alone (17). 

And l-theanine mitigates the downsides of caffeine, such as an increase in blood pressure and anxiety (18).

Recommended product: Focus Now SYM Nutrition

​Ashwagandha (Reduced Anxiety)

Ashwagandha is an Indian herb that’s been used in Ayurvedic medicine for over 3,000 years. It is a potent anxiolytic, which means that it can reduce anxiety levels.

So, if anxiety regularly overwhelms you, or you have an event coming up during where you need to be calmer, supplementing with ashwagandha can offer the solution.

The primary way in which ashwagandha decreases anxiety is by enhancing GABA signaling in your brain. This makes you feel more relaxed (19). 

Besides, ashwagandha is also potent at lowering levels of the “stress hormone” cortisol, which reduces the adverse effects stress has on your body (20).

Recommended product: Organic Ashwagandha capsules by NaturalLife Labs


  • Made with 100% pure organic ashwagandha root extract and powder (root)
  • Has organic black pepper extract to enhance absorption

​Noopept (Increased Memory and Focus)

Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a nootropic that was originally discovered and synthesized in Russia. It's most commonly used to treat age-related cognitive decline, but it’s also popular among those interested in achieving peak mental performance.

The primary benefit of noopept is that it stimulates the expression of BDNF and NGF, as shown by research on rats (21). 

This prevents neuronal degeneration and enhances the growth of new neurons, which, in turn, can reduce age-related cognitive decline and increase memory and focus.

Besides, a study on rats found that noopept also reduces anxiety (22).

And human research suggests that noopept helps with emotional balance by improving irritability, energy, and apathy (23).

Recommended product: Noopept by BrainMedics


  • Buy one gram and get another gram for free
  • 99.9% pure noopept
  • Contains two scoopers so that you can dose safely and accurately


  • Relatively unknown manufacturer

How to use: Take 10 to 30mg sublingual (under the tongue) once a day for up to 56 days. Then, take at least a two-week break before repeating the cycle.
