ADDTabz is marketed as an advanced nootropic supplement and an alternative to Adderall, a prescription medicine used to help increase focus in patients diagnosed with attention deficit hyperactivity disorder (ADHD).

This nootropic claims to improve concentration, enhance focus, boost learning, and increase energy levels.

While the official website for this Adderall alternative says there is no prescription needed, it also says the formula includes synthetic amphetamines.[1]

Should ADDTabz be considered a non-prescription alternative to Adderall? Read our ADDTabz review to find out.


1) ADDTabz at a Glance

  • Claimed to be the natural alternative to Adderall
  • Marketed towards students and professionals
  • Contains a special form of folic acid for brain health
  • Controversial stimulants

2) The Company Behind ADDTabz

ADDTabz is made by Lexium International (formerly known as Gentech Pharmaceuticals).[2]

Based in the United States and the U.K, Lexium International has been in operation for around 25 years.

Their emphasis is pharmaceutical research, but they also sell two supplements through its official website – ADDTabz and PhenTabz, a weight loss and appetite suppressant.

How to contact Lexium International:

  • Address: 1591 Hayley Ln STE 203, Fort Myers, Florida
  • Phone: (888) 666-1714
  • Website: lexiuminternational.com
Nutrition Facts

3) ADDTabz Nutrition Facts

ADDTabz contains the following active ingredients:

  • Ampheta-CDP Proprietary Blend

(Caffeine Anhydrous, Cytidine diphosphate-choline sodium salt, Choline Bitartrate, Synephrine Hydrochloride, and Octopamine Hydrochloride) 375 mg

  • Folic Acid ([6S]-5-Methyltetrahydrofolic acid glucosamine salt) 1 mg

Other ingredients include: dicalcium phosphate, stearic acid, microcrystalline cellulose, magnesium stearate, silicon dioxide, FD&C Red #40 (Lake), croscarmellose sodium, FD&C Yellow #6 (Lake), and pharmaceutical glaze (shellac povidone).

Caffeine is the most popular stimulant in the supplements industry. Being the first in the blend means it gets the most dose, which tells us that ADDTabz has a mental alertness angle to their formula.

Synephrine is actually a stimulant-burner, or an ingredient that energizes you by burning more fat. It works well with caffeine, though some suggests putting the two together pose risks of palpitations and mild hypertension.

Octopamine is banned by the World Anti-Doping Agency (WADA) for use during competitive sports. Yet, the substance is still present in some dietary supplements, including ADDTabz.

Choline Bitartrate is the cheapest form of choline. It’s often added to help stimulate the brain, but needs upwards of 250 mg to bypass the blood-brain barrier.

Potential Side Effects

5) Potential Side Effects from ADDTabz Ingredients

Despite ADDTabz being advertised as a side effects-free nootropic, some ingredients included in this formulation are associated with mild and moderate adverse effects.

Synephrine taken by itself or with stimulants such as caffeine or caffeine-containing herbs may increase the risk for fainting, high blood pressure, stroke, heart attack, and other severe side effects.

There are reports that synephrine can trigger headaches, including migraine and cluster headaches, in some people.[17]

Caffeine anhydrous is another ingredient that may cause side effects, especially in people sensitive or with low tolerance to caffeine.

Common side effects of heavy caffeine use include[18]:

  • Headaches
  • Jitters
  • Trouble sleeping
  • Restlessness
  • Anxiety
  • Nausea
  • Lack of appetite
  • Diarrhea
  • Rapid heartbeat
  • Chest pain

6) What You Need to Know Before Taking ADDTabz

Medications for depression (MAOIs) interact with Synephrine. Some of these medications used for depression include Tranylcypromine (Parnate) and Phenelzine (Nardil).[19]

Caffeine anhydrous is known to interact [20][21] with stimulant prescriptions like Ephedrine. Taking caffeine and Ephedrine may cause too much stimulation and sometimes severe side effects and heart problems.

Caffeine is also known to have moderate interactions with many other prescription drugs and dietary supplements.

7) ADDTabz – Legit or Scam?

In 2012, the FDA began sending warning letters to supplement manufacturers selling DMAA (1, 3-dimethylamylamine), a controversial stimulant FDA has been working to remove from the market since 2012. [22][23]

In 2013, despite being warned by the FDA, Gentech Pharmaceuticals continued including DMAA in several of its formulations: ADDTabz and the weight-loss products PhenTabz and PhenTabz-Teen.

Starting in 2014, Gentech Pharmaceuticals began morphing into Lexium International. Lexium continues to sell PhenTabz and ADDTabz, but it has removed the DMAA from the formulation.

Buying Options

8) Where to Buy ADDTabz in the United States?

Online, ADDTabz can only be bought from Lexium’s website and several retailers such as eBay.


9) ADDTabz Price

ADDTabz list price is $69.00 (30 tablets / one month supply). A two-bottles deal for $128.00 is also available.


10) Directions For Taking ADDTabz

For adults, take one (1) ADDTabz tablet on an empty stomach, half an hour before breakfast or lunch.

11) What the Customer ADDTabz Reviews Say

"One bottle thus far, no noticeable difference until near the last few pills. Stamina is better, yet it doesn't last very long, maybe 4 hours? I take two pills in AM on an empty stomach. One pill alone did not produce any noticeable results. " [Read full review]


"I really like this product. It does not give me that dead focus as some talk about, but it helps me stay on task. I still procrastinate on taking it because I know when I do, it's work mode. It is the best product I have used for my ADHD with/without a prescription. I wish that the VA offered this product. It is a superior option." [Read full review]

---Michael Ivory

"The product does exactly like it's supposed to and is not only comparable to its Rx counterpart but is probably better for you!" [Read full review]



12) Our Verdict on ADDTabz

To conclude our ADDTabz review, it’s a bit of a mixed bag.

While we like how this supplement may help improve your cognitive function, we are never a fan of nootropics that pretend to be an efficient alternative to a prescription.

Then, there’s also the fact that it’s a stimulant disguised as a nootropic. It contains more energy boosters than actual brain health ingredients, which tells us it’s in the wrong supplement category.

If you decide to use this product, we highly recommend you speak to your healthcare provider before using it.

This is an effective product, but with all pharmaceuticals it has some side effects.
