Best Keto Nootropics Review: A Buyer 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. We’ll also share with you some possible side effects and when NOT to take them. 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 it’s always best to optimize brain functioning by focusing on getting enough sleep, maintaining a healthy diet, and following a proper exercise plan.

Research shows that nootropics may inadvertently cause adverse psychiatric effects. One study found that commonly used nootropics may cause the following side effects (2):

  • Headache
  • Diarrhea
  • Nasopharyngitis
  • Gastrointestinal discomfort
  • Fatigue
  • Insomnia or restlessness
  • Tremors
  • Memory loss or impairment
  • Dysphoria
  • Dizziness
  • Motor function impairment
  • Vertigo
  • Agitation
  • Feeling hot
  • Psychomotor agitation

The study outlined four different cases of individuals taking nootropics who experienced psychosis outbreaks. All cases involved subjects between the ages of 17-28. 

The most commonly reported side effects were depression, psychosis, paranoia, self-injuring behavior, substance abuse, anxiety, and insomnia. Three of the four patients were admitted into the hospital.

Don’t take nootropics if you take medications for anxiety or depression. Also, consult your doctor if you have any questions about the possible negative effects of nootropics based on your medical history.  

That said, nootropics are generally believed to be safe as long as you use them properly, 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. No matter how potent an ingredient is, if it’s not available in the right amount, it’s still ineffective. Additionally, consuming too much of an active ingredient could have dangerous effects.
  • 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.
