CILTEP® is a nootropic stack that consists of natural nootropics and was developed to help us achieve better focus, concentration, and to improve our memory. It is one of many products of Natural Stacks company, which used to be one of the world’s first open-source supplement company with a strong mission to help people naturally achieve better results. 

And that’s the main reason why CILTEP is a product that brings a lot of attention. 

But does it work? And is it worth your money? Let’s check out our full CILTEP review.

What Is CILTEP? 

CILTEP (pronounced “siltep”) is a natural nootropic supplement. It was designed for entrepreneurs, managers, athletes, and other professionals.

Compared to many other nootropic stacks that we tried and reviewed, CILTEP nootropic has the most straight-forward formula with one of the lowest amount of different ingredients in the formula.

At first, we thought that was its advantage. But we changed our mind later on.


CILTEP was designed to help you unleash your full potential. It has a very unique and simple formula that may provide multiple benefits. It is especially designed for increasing your energy, enhancing your mood, and focus. It was particularly made for people who need additional brainpower.

While many similar supplements contain a wide variety of potentially effective nootropics, CILTEP stands out with a small amount of well-studied ingredients. 

It is not a typical brain supplement for improving memory, but it was designed to offer full cognitive support. It might be also beneficial for people with ADD and ADHD.

Let’s have a look at what exactly does CILTEP does to our body.

Ciltep Review

cAMP Levels

The cAMP is a messenger that is important for many biological responses. One of its primary roles is to help neurons create better pathways in our brains. This can be naturally done by supplementing forskolin, which is a popular nootropic. 

CILTEP contains Coleus Forskohlii herb that contains forskolin. By taking the recommended daily dosage, your body intakes about 4 mg of forskolin. 

This is one of the main reasons that CILTEP may provide long-term benefits.

Brain Fog

CILTEP is formulated in a way that helps people achieve a higher state of concentration. By doing that, people often report that they have fewer issues with brain fog. 

Based on our experience, CILTEP is not that effective in helping with brain fog. 

PD4E Production

PDE4 is a critical enzyme that is involved in the production of inflammatory mediators. This enzyme is the best known in the correlation with the immune cells. You need some PDE4 to get rid of old unimportant memories. However, some people have it too much and others too little. 

To boost your memory, you should limit PDE4. CILTEP contains quality Artichoke extract, which can help to inhibit the PDE4 formation. This is important to have a great memory.

By taking CILTEP every day, you get 900 mg of Artichoke extract in your body, which is probably enough to achieve the desired effects.

Dopamine Production 

Dopamine is an organic chemical that works as a neurotransmitter and a hormone in our body. CILTEP can create a healthy balance of dopamine, which is essential for optimal focus and cognition. 

This nootropic stack contains L-Phenylalanine and vitamin B6, two important nutrients for overall cognition. Among other benefits, they keep cAMP levels high. Also, they ensure a steady dopamine production.

Taking CILTEP pills every day may ensure you get enough energy, you feel more alert, and your memory improves.

CILTEP Ingredients

CILTEP nootropic has a 100% natural, open-source formula. Its formula is suitable for vegans, it is non-GMO, gluten-free, and paleo-friendly.

Here is the list of all ingredients in CILTEP:

  • 900 mg Artichoke extract
  • 20 mg Forskolin
  • 750 mg Acetyl-L-Carnitine
  • 5 mg Vitamin B6
  • 500 mg L-Phenylalanine

This CILTEP formula is based on taking three capsules.

Artichoke extract

Artichoke extract contains Luteolin, a natural inhibitor of PDE4. Studies have correlated lower levels of the enzyme PDE4 to significant increases in normal mental performance. This includes an increased cognition, improved long-term memory, increased wakefulness, and neuroprotection.


Forskolin is derived from the plant Coleus forskohlii. Combined with Luteolin from Artichoke Extract, forskolin is theorized to increase the duration of cAMP in neurons synergistically.

Vitamin B6

Vitamin B6 is an essential vitamin and a crucial enzymatic cofactor in normal metabolic and psychological function.


Acetyl-L-Carnitine is an amino acid that helps combat feelings of brain fog and fatigue.


L-Phenylalanine is a common amino acid that you can get plenty of from eating food rich in proteins. Studies show that this amino acid may be beneficial for treating depression and skin disorders. Besides, it plays an important role in the synthesis of dopamine.


According to Natural Stacks, it is recommended taking 1-3 capsules of CILTEP on an empty stomach.

At the beginning of our test period, we only took 1-2 capsules, but then we added the 3rd capsule as well. 

We definitely noticed a difference between taking 1 or 3 capsules, however, the effects were to weak to recommend this supplement. 

Where To Buy CILTEP Nootropic?

So, do we recommend taking CILTEP?

Sadly, not anymore, because there are so many better nootropic supplements on the market. CILTEP is not as effective as many of our top-rated nootropic supplements. It used to be a great stack, but competitors managed to develop far advanced nootropic supplements.

Check our final recommendation below.


Your Inception does not recommend supplementing CILTEP. Based on our detailed review, CILTEP used to be one of the best and most popular nootropic stacks on the market. Sadly, competition has arrived and developed much better nootropic stacks.

Since 2019, we no longer recommend it. But don’t understand us wrong; CILTEP is not a bad supplement -there are just better alternatives available.
