How We Tested NZT-48?

In order to conduct a comprehensive assessment of NZT 48, our staff members carried out a 45-day trial to evaluate its effectiveness and potential side effects. The trial involved taking the supplement as per the recommended dosage and monitoring the results over the testing period.

Throughout the trial, our staff members reported positive outcomes with NZT 48. They observed significant improvements in focus, concentration, and overall cognitive performance. Many individuals noted heightened mental acuity, increased problem-solving abilities, and improved memory retention, which contributed to enhanced productivity and efficiency in their daily routines

However, it is crucial to acknowledge that there were some reported side effects during the trial. A few individuals experienced mild headaches, irritability, and difficulty sleeping initially. These side effects tended to subside after the first few days as the body acclimated to the supplement. It is important to note that the occurrence and severity of side effects may vary among individuals.

Overall, based on our 45-day trial, NZT 48 exhibited promising results in terms of enhancing focus and cognitive function. However, it is essential to consider individual differences and consult with a healthcare professional before starting any new supplement regimen.

What Does NZT-48 Do?

The ingredients in NZT-48 may increase levels of key brain neurotransmitters like GABA, serotonin, dopamine, and acetylcholine. This could improve cognitive functions like memory, learning speed, focus, concentration, and information processing.

An article by Michael E. Hasselmo published in Current Opinions in Neurobiology discussed the key role the neurotransmitter acetylcholine plays in improving memory and learning [1].

It could also improve mood and decrease anxiety. GABA blocks specific receptors in the central nervous system to lower levels of stress. NZT-48 also improves cerebral blood flow for enhanced focus and alertness and better brain health in general.

Other ingredients in the formula may boost cellular health, and improve communication between nerve cells. The formula is full of free-radical killing antioxidants which lower oxidative stress. This helps repair neuronal damage as well as strengthen the immune system.

A review by Kyung Hee Lee, Myeounghoon Cha, and Bae Hwan Lee published in the International Journal of Molecular Science discussed the neuroprotective impact of antioxidants in cerebral health [2].

NZT-48 is also high in anti-inflammatory agents which reduce swelling for enhanced overall brain health. The green tea contains some caffeine, which as we explained in our review of Jet-Alert, could boost your energy levels and improve alertness and focus.

A review published in Phytomedicine by Edele Mancini, et al presented evidence showing the positive effects of green tea on cognition, mood, and human brain function [3].

NZT-48 Limitless Pill Ingredients

These are some of the primary active ingredients:

Grape Seed Extract

Rich in flavonoids and polyphenols, these antioxidant-rich seeds have potent health and immunity properties. They also boost levels of the brain neurotransmitter serotonin, which could have an impact on improving mood and decreasing depression.

A review in the International Journal of Pharmaceutical and Clinical Research by Souad El Gengaihi and Doha Abou Baker explored the research supporting the potency of grape seeds as brain health promoting food [4].

This is a primary brain inhibitory neurotransmitter involved in stress and anxiety, as it blocks specific central nervous system receptors. It has benefits for general brain health, and could also help decrease blood pressure and muscle spasms.

A research review published in the Neuroscientist explored emerging research on the brain chemical GABA and its potential from inhibition to cognition [5].

Bacopa Monnieri

This herb may boost the synthesis of brain neurotransmitters like serotonin, dopamine, and GABA, as we mentioned in our review of Mind Lab Pro. It helps to improve mood, enhance cognitive functions like memory and learning, and decrease levels of stress and anxiety.

Bacopa Monnieri also has potent antioxidant potential and may help strengthen the immune system. A review published by Sebastian Aguiar and Thomas Borowski in Rejuvenation Research explored the neuropharmacological benefits of bacopa monnieri [6]

Summary: NZT-48 Brain Booster works to improve cerebral blood flow, repair neuronal damage, enhance cellular communication, and increase levels of key brain neurotransmitters involved in learning, memory, and mood.

There were customers who said it gave them great improvements in memory, mood, and focus, while others cited few results. These are some of the customer comments, to give you an idea of the general feedback for NZT-48.

Didn’t Do Much For Me

Took NZT-48 for a couple of months, and honestly, I did not notice any difference at all and stopped taking it. I guess it was worth a shot, but it does seem like a waste of my hard-earned money. ~ John R.

Great Energy and Focus!

Wow I am getting great results from the NZT-48 supplement! It revs up my energy, sharpens my memory, and give me added focus and motivation for the day. Love it! ~ Jenny V.

I Felt Some Lift in My Mood, But No Memory Improvement

I took this product for a few weeks, but it didn’t really do what it said it was going to do in terms of cognitive benefits. I didn’t get that, but I did notice a slight improvement in my mood. However, that did not make it worth the monthly cost. ~Joey G.


NZT-48 Brain Boost is an organic nootropic supplement which promises to enhance cognitive functions like memory, learning, focus, and information processing, as well as improve mood and decrease anxiety. While you can find it online for a decent price, there is no information about the manufacturer and no guarantee.

The customer reviews for NZT-48 Brain Booster were really mediocre overall. Of course there were a number of users who said that the supplement offered great benefits for mood and brain health, however, just as many people mentioned that they got few noticeable results.

NZT-48 is a 100% organic product which does not include artificial or chemical additives. However, it’s possible that some users could experience mild side effects. If you have serious symptoms, discontinue use immediately. Prior to taking this supplement we advise you to get medical approval from a physician.

More than ever people of all ages are struggling with memory problems. People are unable to disconnect from their work, while students are under immense pressure to perform. Brains are overloaded with information that must be remembered.

Memory products should help to optimize overall mental health and brain function. Most importantly a memory product should work safely and gently to promote cognitive function.

Below you'll find some of the most effective memory products on the market today, in our opinion.
