Synagen IQ is a dietary supplement claiming to increase cognitive performance and brain health. It is promoted as the most advanced natural memory enhancement product, but is it really effective? Read my comprehensive Synagen IQ review to find out.

What Is It?

Synagen IQ

Synagen IQ is an advanced cognitive enhancer developed to enhance cognition, focus, attention, concentration and improve brain function and health. It was developed in the US, but upon my research, the company Synagen is not operating anymore.

It was closed a while ago after having over 18 complaints about unauthorized charges, unresolved refund disputes, and false advertisement. Despite that, some users are still searching for the Synagen IQ supplement. 

Synagen IQ claims to:

  • Boost focus
  • Improve memory 
  • Heighten reactions

I was informed that Synagen IQ is a scam, which caught my interest to review it. I definitely don’t want scammy supplement brands on the market. But when I decided to try it or get more information about it, the company was already shut down. 

So this review is based on the information I could find about Synagen IQ online. Let’s check the ingredients you could find in Synagen IQ. 


Synagen IQ contains 11 nootropic compounds, including vitamins B3 and B6. It has a pretty clean formulation, but the ingredients are underdosed. 

The ingredients in Synagen IQ are:

  • Vitamin B3
  • Vitamin B6
  • Caffeine
  • GABA
  • Bacopa monnieri
  • Alpha-GPC
  • L-Theanine
  • Phosphatidylserine
  • L-Tyrosine
  • Vinpocetine
  • Huperzine A

A quick glimpse of the Synagen IQ ingredients list doesn’t show all the bad things about it. I had to dig deeper to understand why this formulation is not optimal.

Vitamin B3

Vitamin B3 (niacin) is an essential B-vitamin that supports the function of many enzymes. [*] It is a vital nutrient for enhancing bodily functions. Vitamin B3 deficiency can lead to fatigue, constipation, vomiting, depression, headaches, and even memory loss. [*]

Synagen contains 30 mg of niacin. However, B3 is commonly found in many foods, so adding 150% of your RDI to this nootropic supplement doesn’t make too much sense.

Vitamin B6

Vitamin B6 (also known as pyridoxine) is a water-soluble vitamin important for protein, carbohydrate, and fat metabolism. [*]

Supplementing vitamin B6 may improve mood, promote brain health, and improve eye health. [*][*][*]

The RDI (recommended daily intake) is 1.3 mg.

Alpha GPC

Alpha GPC is a cholinergic compound that increases the amount of acetylcholine in our brain. [*] Supplementing Alpha GPC may slow down cognitive decline and improve memory. [*]

Sadly, we don’t know the Alpha GPC dosage in Synagen IQ. 

Bacopa Monnieri

Bacopa Monnieri is an adaptogen herb and a very effective nootropic supplement. Several studies show that supplementing an extract of Bacopa Monnieri enhances memory function in healthy individuals. [*][*]

It can also slow down cognitive decline and help people with symptoms of medical disorders like  Alzheimer’s disease, anxiety, ADHD, stress and many other conditions. However, we don’t know the exact dosage in Synagen.


Caffeine is a powerful stimulant that improves energy levels, physical strength, and endurance. [*] It enhances performance and ensures prolonged wakefulness. [*

We don’t know the caffeine dosage in Synagen IQ. Since caffeine is a stimulant that can increase the heart rate, not knowing the dosage is troubling.


GABA is the inhibitory neurotransmitter that counters glutamate. [*] Limited evidence shows that supplementing GABA may help with anxiety, insomnia, stress, and high blood pressure. [*] However, GABA as a supplement cannot cross the blood-brain barrier, so its use in supplements is useless. 

Huperzine A

Huperzine A is a powerful nootropic compound that may increase acetylcholine levels in the brain. [*]

Due to its short half-life and potential side effects, you need to cycle Huperzine A. We don’t know the optimal cycle period. 


L-Theanine is an amino acid that is found in black and green tea. Using it shows positive effects on focus and attention. [*] It can also induce calmness. 

Again, we don’t know the amount of L-theanine in Synagen IQ. 


L-Tyrosine is a nootropic that is effective for people in stressful situations. 

Studies show that supplementing NALT enhances cognition in animals and adults. Supplementing NALT is beneficial for people with ADHD [*], and it promotes cognitive flexibility in healthy adults. [*]

The recommended daily dosage is 200-2000 mg. 


Phosphatidylserine is a known phospholipid and essential building block of brain cell membranes. Supplementing phosphatidylserine shows positive benefits of cognitive performance, especially in the elderly. [*]

We don’t know the dosage and the quality of this nootropic in Synagen IQ. 


Vinpocetine is a nootropic compound from the Periwinkle plant used as a cognitive enhancer. [*] Vinpocetine may reduce reaction times and even improve memory in normal healthy volunteers. [*] It may also slow down cognitive decline in patients with chronic brain ischemia. [*]

Vinpocetine is taken in the range of 15-60 mg. 

Opinion About The Formula

Synagen IQ has a decent formulation, but we lack all important data about the supplement. We don’t know the amount of each compound, and we lack data on the quality of the ingredients. 

Proprietary blends that contain caffeine are troubling because companies often increase the amount of caffeine due to its potency and low cost and decrease the amount of other crucial nutrients. This results in feeling the effects of a nootropic supplement for entirely the wrong reasons.

Ideally, a nootropic supplement should be caffeine-free, but that’s not the case with Synagen IQ. 

Also, top-quality supplement brands invest heavily into using branded nootropic extracts to boost cognitive function. Synagen IQ contains no branded compounds, which tells that they saved money on the ingredients.

Combine this with the fact that they offer no money-back guarantee, and you can immediately know why this supplement is problematic.

I cannot recommend supplementing Synagen IQ because of all the mentioned reasons. 

Side Effects

Not knowing the exact amount of all nootropic compounds in Synagen IQ can mean that this nootropic supplement is potentially harmful and can bring a lot of side effects.

I checked many Synagen IQ reviews of actual users, and what I found out is the fact that many people report it as false advertising since there are no effects whatsoever (including the lack of positive benefits). I believe the reason for such low performance of this supplement is that it is simply underdosed.

However, if you take a high dosage of caffeine,+, you can quickly experience the following side effects:

  • Nausea
  • Headache
  • Stomach cramps
  • Insomnia
  • Anxiety
  • Sweating

Similar side effects happen if you overdose on Huperzine. Also, supplementing GABA may lead to an upset stomach, sleepiness, headache, and muscle weakness. 

It is unclear if Synagen IQ causes those side effects since it is not available for sales anymore. But if you still own a bottle of this nootropic supplement, I suggest avoiding it to avoid potential side effects. 

How To Take It?

The official brand website is inaccessible since the company does not exist anymore. Therefore, I cannot give you any exact data on how to take Synagen IQ. 


Synagen IQ is probably underdosed, it lacks quality ingredients, and may be potentially harmful. The company is not in the business anymore, so it isn’t easy to assess if it was trustworthy. 

Due to the many complaints, it seems that the business was trying to scam the people. Therefore, it is hard to believe that Synagen IQ was actually a beneficial supplement. 

Synagen IQ contains potent nootropics, but also risky nootropics like Huperzine A and ineffective compounds like GABA. Since the brand didn’t disclose the amount of each compound per serving, it is not advised to take it. 

Is It Hoax?

Data shows that Synagen IQ may be a hox. Many negative customer reviews, no money-back guarantee, and problematic ingredients show that Synagen IQ is not trusted. 

Customer Feedbacks

Published customer reviews show that the Synagen company was acting scammy.

"Bought A PRODUCT AND WAS SUPPOSED TO PAY $10 SHIPPING and was charge $140 on my credit card statement. Not what i agreed to. Purchased to products with the understanding all I had to pay was shipping $10. When my credit card statement came there was a charge for $140. Contacted company and all I could get was a answering service and a run around. I was told I had to wait for the product to arrive and fill out a form to get a rebate. Again this was never disclosed. I was robbed of $110 of my hard earn money."

"This product is a very clear example of a total rip off. I fell hard for this scam. I am 68 and beginning to have memory problems and thought this might help. What a joke. Synagen IQ probably does not even have anything in it. It is probably flour or something similar. I bet these scam artists are worn out from running back and forth to the bank. I wish there was a way to shut them down. They should not be scamming everyone."

"This is a SCAM!!!! Not an honest Business. I cancelled my order immediately the same day I ordered it, and the very next thing I know they charged my card. I have contacted them many times by way of email. They overcharged my card and told me that I had to follow the terms and conditions when I ordered it and take the product for 60 days before I can get a refund. That is if the product doesn't perform as it is suppose to. I cancelled this product 4 days prior to it was shipped and they still sent it and charged me. I told them I never received a receipt or the terms and conditions upon ordering. This is a SCAM!!!!"

Where To Buy It?

You cannot buy Synagen IQ anymore. The company was shut down, so their supplement is not available for sale anymore. 

Luckily, there are many more effective and safer nootropic supplements on the market. Check below my final verdict. 


My Synagen IQ review showed that Synagen IQ was not a trustworthy nootropic supplement. It was developed by a risky brand that was recently closed due to the many complaints. It contained a few potent nootropics, but the brand did not disclose the exact ingredient dosage.

Proprietary blends are problematic for several reasons, which is why I recommend avoiding them altogether. The fact that Synagen contains GABA is enough to steer me off this supplement. Also, not knowing the exact amount of caffeine content is troubling. 

In addition, data and customer reviews show that Synagen IQ does not provide the promised benefits. If you want to improve your cognition, invest in a high-quality supplement that actually works.
