This page was last updated June, 2024

Intro to AdderRx – What Is It?

AdderRx is a nootropic/brain supplement from Nexgen Biolabs, Inc. This company is relatively popular in the U.S., known for its dietary supplements and nutraceuticals.

Nexgen Biolabs, Inc. created AdderRx as a non-prescription alternative to Adderall. It designed the product to increase users’ focus, memory, and overall mental energy.

Benefits of Using AdderRx Nootropics

Some users claim that the nootropic helps boost their focus, learning, memory, and other brain functions. However, from our experience and other reviews, we think that the benefits are mild at best. The supplement is also infamous for causing ill side effects.

Pros of AdderRx

  • Some users report that it provides more energy and focus
  • Affordable
  • 100% money-back guarantee

Cons of AdderRx

  • Doesn’t disclose how much of each ingredient is present
  • Not evaluated by the Food and Drug Administration
  • Lots of negative customer reviews online
  • High potential for adverse side effects

What Is AdderRx Designed to Do?

Nexgen Biolabs designed AdderRx as a non-prescription version of Adderall. It’s not necessarily for helping people manage conditions like ADHD. Instead, its purpose is to give college students and working professionals an extra edge. According to Nexgen Biolabs, this product:

  • Enhances mental energy and clarity
  • Boosts cognitive functioning
  • Supports alertness and concentration
  • Increases memory recall

AdderRx Ingredients

Product label on AdderRx bottle

AdderRx uses a proprietary blend. While we don’t know exactly how much of each ingredient is present, we know that the formula contains:

DMAE – a popular ingredient in nootropics. There isn’t much research on its benefits, but some studies suggest that it can support memory and reduce hyperactivity.
Caffeine – a powerful stimulant that can ward off fatigue and promote cognitive functioning. However, consuming too much can have ill side effects. The fact that we don’t know how much caffeine is in AdderRx is concerning.
L-theanine – promotes relaxation without causing drowsiness. It helps reduce some of the harmful side effects caffeine can have.
CDP-choline – one of the most effective cognitive enhancers out there. However, you need a dose of around 200 mg for it to be effective.
Beta-phenylethylamine – your body naturally makes plenty of beta-phenylethylamine. You shouldn’t try to supplement this ingredient, especially when there are other stimulants involved.
Synephrine HCL – many nootropics and weight loss supplements use this stimulant. However, no reputable studies show that it has any real health benefits. Also, it may cause ill side effects.
Hordenine – Also known as N,N-dimethyl-4-hydroxyphenylethylamine is in many supplements. It can stimulate the central nervous system but doesn’t have any real impact on cognitive function [1].
Schizandrol A – a filler ingredient. We cannot find any studies that show it promotes focus and energy [2].

What We Think of the AdderRx Formula

Some consumers are okay with proprietary blends. After all, isn’t the company just trying to protect its formula?

While this sounds like a convincing argument, we aren’t buying it. Companies should be transparent about what they sell to their consumers – especially when it’s a product that could affect how your brain functions.

In general, we dislike proprietary formulas like AdderRx’s. There could be potentially dangerous amounts of individual ingredients. Or, there could be minimal amounts of nootropics that prevent the product from working as it should.

How Does It Work?

AdderRx works like other supplements. After consuming the pill, your digestive system will break it down. It will eventually make its way into your bloodstream and act on your nervous system.

Keep in mind that food in your stomach will cause the pill not to digest as quickly. It’s best to take the pill a couple of hours before or after eating.

Who Will Benefit from Using AdderRx?

This product is not ideal for vegans and vegetarians, seeing as it uses gelatin. It is also not for pregnant/breastfeeding women, children under the age of 18, etc. Because of its stimulants, it may present a danger to those with preexisting health conditions.

With all these exceptions aside, the supplement may benefit:

  • College students with a heavy workload
  • Working professionals with stressful deadlines
  • Exhausted parents
  • Anyone who needs extra focus in their busy life

How It Feels

The pill might take several minutes to work, especially if you consume it close to a meal. Once it kicks in, you may feel a slight boost in mental focus and energy. We haven’t found that it significantly improves learning or memory.

AdderRx Side Effects – Is It Safe?

If you have high blood pressure or a related condition, this supplement may be unsafe. It may cause side effects, including:

  • Sweating
  • Dizziness
  • Nausea
  • Headaches
  • Insomnia
  • Heart palpitations
  • Hypertension

How Do You Use AdderRx?

AdderRx is straightforward to use. NexGen Biolabs recommends taking one pill per day. You should take it on an empty stomach with a glass of water to feel its full effects.

Note: The company emphasizes that you should not take more than one capsule in 24 hours. This cautionary note leads us to believe that there are excessive quantities of at least one ingredient.

AdderRx FAQs

Does AdderRx Work?

This product may give you a little edge when it comes to focus and clarity. However, it’s not a miracle pill. The effects are mild and will vary depending on the consumer.

AdderRx vs Adderall

AdderRx is no substitute for Adderall, even though the company markets it as such. The latter is much more potent and more effective at improving learning, concentration, and memory. Additionally, Adderall requires a prescription. It also can be habit-forming and may cause more severe side effects.

Overall Review

  • Short-Term Cognitive Effects
  • Long-Term Cognitive Effects
  • Safety
  • Price


Some customer reviews suggest that this supplement boosts their focus and lifts brain fog. However, we found that its mild benefits are not worth it. We don’t know what’s in it precisely, leaving users at-risk for potential side effects. We recommend choosing a different nootropic that is more effective and transparent about its ingredients.


  • May provide benefits, including improved concentration, heightened alertness, etc.
  • Comes with a money-back guarantee
  • Affordable compared to other nootropics


  • Not evaluated by the FDA
  • Not transparent about how much of each ingredient it contains
  • Generally negative reviews
  • Likely to cause adverse side effects

Where Can I Buy This Product?

If you want to buy AdderRx online, we recommend buying it straight from Nexgen Biolabs’ website. We have found no reputable third-party online retailers. If you want to buy Adderrx in stores, the product is available at some Walmart locations.

With that being said, we do not recommend buying AdderRx based on our review. Simply put, there is a much better nootropic supplement available. Instead we recommend you try the nootropic supplement we rated at #1. It is on sale until 16th June 2024.
