What is it?

NZT 48 is a nootropic supplement that takes its name from the film “Limitless”. In the movie the main character, portrayed by Bradley Cooper, is given a pill called NZT 48 that makes him smarter than any human can naturally become.

While it is in no way related to the film or the fictional product that it portrays, it does still advertise itself as having cognitive performance effects on the user. They claim that it can help improve memory, problem solving, thinking speed, and stress management, however these benefits are not likely to resemble the unrealistic powers granted by the pill in the movie.

The nootropic supplement that users have gotten the most benefit from is called Memotenz. It is a highly effective memory aid and mental performance booster that is recommended by our panel of experts above the other brands of products of this nature.

It has shown the most usefulness in terms of information storage and recall, problem solving skills, alertness and attention. Click here to see more about how Memotenz works chemically.

NZT 48 Ingredients and Side Effects
Acetyl-L-Tyrosine Acetyl-L-Carnitine
Rhodiola Rosea Arginine AKG

Acetyl-L-Tyrosine: An amino acid that is made naturally by the body but that can also be found in meat, dairy, eggs, and legumes. Tyrosine is taken by some people as a mental performance supplement.

It has been used to try to treat several conditions that are related to cognitive function, such as ADD, Alzheimer’s disease, depression, and dementia, however it was not successful enough in these applications to claim that it is effective for treatment. It has shown some usefulness in improving memory, alertness, and mental performance in stressful conditions.

Most people react relatively well to tyrosine, given that it occurs naturally in the body. There are some people that have experienced side effects that are possibly related to its consumption including:

  • Nausea
  • Headache
  • Heartburn
  • Joint pain
  • Fatigue
  • Overactive thyroid function

Acetyl-L-Carnitine: An amino acid that the body uses to help generate energy. It is used for heart, brain, and muscle function, and it may have some positive impact on neurological function as well.

Carnitine has not been shown to increase memory function in all users, however it has shown some benefits for the elderly and for alcoholics. It does increase levels of blood flow to the brain, which can have positive effects for cognition in some individuals, particularly those suffering from Alzheimer’s or dementia.

Carnitine has been linked to some potential side effects, which may include:

  • Gastro-intestinal distress
  • Restlessness
  • Fishy odor of the skin, sweat, and urine
  • Seizures
  • Hyperthyroidism

Rhodiola Rosea: An adaptogenic herb that is used to improve attention and mental functioning. Rhodiola rosea is often called arctic root because it is found growing in particularly cold, mountainous regions.

Rhodiola has been used to improve mental performance since the days of the ancient Greeks. It is thought that it can lengthen cell life, improve learning and memory, and help improve heart health. There is little data that backs up these beliefs.

Rhodiola has not been associated with any side effects in the short-term. There is not much information about the effects of taking it every day for a prolonged period of time, however there is no data that currently suggests it may be harmful to its users.

Arginine AKG: A combination of the amino acid L-Arginine and the chemical alpha-ketoglutarate. Taken together they are a potent circulatory aid that can be beneficial for testosterone function as well.

L-Arginine is mostly known for its effects in male enhancement products and for its use in some circulatory system and blood pressure treatments. Alpha-Ketoglutarate is regarded as an athletic performance supplement that is useful for helping build new muscle and preventing the breakdown of old tissue.

Neither L-Arginine nor AKG has tested positively for benefits to users’ mental performance. While blood flow to the entire body is increased, there have been no indications that this will have a beneficial effect on cognition.

Arginine AKG is safe for most users, however it can cause changes in blood flow that can have negative effects on individuals with preexisting heart and circulatory issues. Those individuals are encouraged to talk with their health care providers before beginning to take Arginine AKG on a daily basis.

NZT 48 Quality of Ingredients

NZT 48 does not have the type of ingredients profile that would lead to the effects that their advertising claims that it has been making. Amino acids are a critical part of the body’s biological functioning, however they do not tend to provoke outwardly noticeable effects in users, especially in terms of mental performance.

Many nootropic supplements are very obvious in their effects. It is possible to feel the chemicals working and to see their results, leading to little ambiguity about their effectiveness. It is highly unlikely that a user would perceive a noticeable change in cognitive functioning, especially in the short-term.

It is possible that over time users will be performing at slightly elevated levels compared to before they began taking NZT 48, however this is by no means a “limitless” pill and users should not expect it to perform as such. It is unlikely that NZT 48 can have too many negative effects on healthy users, however it is equally as unlikely that they will notice any particularly positive ones either.

The Price and Quality of NZT 48

NZT 48 is one of the most expensive nootropic supplements on the market today. As of the date of this review’s publication, this is the price that it was retailing for:

  • 1, 8-dose box of NZT 48 tubes: $54.70

The directions for NZT 48 indicate that it is meant to be taken as a daily supplement, and the ingredients are such that it is unlikely to be effective if it is not taken as directed. This means that NZT 48 will cost users well over $150 per month, a shockingly high figure that is well outside the range of almost every other nootropic supplement.

Customer Opinions of NZT 48

The online reviews of NZT 48 are not particularly favorable. The most common rating on Amazon is one star, their lowest possible mark. These are some remarks from past customers:

“After taking this stuff I was sick for days. My stomach is just starting to get back to normal.”

“I saw the movie, and even though I knew it wasn’t going to be like that I was expecting something good. Instead I got just plain nothing from these useless pills.

“Made me vomit. Tried it again, vomited again. I guess I really do need brain pills.”

The most frequent issue that people brought up was that the pill didn’t seem to offer them the same benefits that were promised in the advertising. There were almost as many complaints about the side effects that it caused users, mostly related to stomach upset, diarrhea, and vomiting.

Conclusion – Does NZT 48 Work?

The customers that went in expecting NZT 48 to work like it does in the movie were very disappointed by the real-world product. NZT 48 is not well classified as a nootropic agent, as the amino acids in its blend have little chance of actually improving users’ mental performance.

They have a decent chance of helping users general biofunctions, however it is unlikely that these effects will be noticeable to the consumer themselves. Customers that are seeking a study aid, energy booster, or help with focus and concentration will probably be disappointed, especially in relation to how much they’re paying for it.

The nootropic supplement that has the most potent blend on the market is Memotenz. Their blend has been thoroughly vetted by our team of experts, who rated it as the top mental performance aid available without a prescription.

Their ingredients mix is a sophisticated combination of basic amino acids with highly effective herbs and chemicals that work together to help users maximize their mental potential. Click here to see the full ingredients panel for Memotenz.
