How to Take CILTEP

In order to boost mental performance to the highest degree, one should take a serving of 2 to 3 capsules immediately after waking up on empty stomach. The dosage should not be exceeded to more than three capsules on a single day.

While CILTEP can be consumed daily, the manufacturer suggests that it is better to take 1 or 2 days off on every week.

According to the online reviews people have reported feeling more alert and aware of their surroundings, able to process information better and in general feel more energetic and active.

What Are The Ingredients of CILTEP?

Here is a close look at the ingredients of CILTEP:

  • Artichoke Extract: Artichoke Extract is filled with Luteolin, a natural inhibitor of enzyme PDE4. The PDE4 enzyme can be found in neurons and it helps to break down CREB thereby activating cAMP. The process of CREB activation is vital to long-term potentiation which can aid in learning and memory. Research has revealed that inhibiting PDE4 and increasing cAMP levels within neurons is critical for boosting long-term potentiation.
  • Forskolin: Forskolin is a substance derived from Coleus forskohlii plant. It is used extensively in Indian Ayurvedic medicine. The substance can enhance cAMP levels in cells. When combined with Luteolin, it can synergistically enhance the levels and duration of cAMP in the neurons.
  • Acetyl-L-Carnitine (ALCAR): ALCAR or Acetyl-L-Carnitine is an acetylated version of amino acid L-Carnitine. This amino acid is present in numerous foods and can also be easily synthesized in liver. The functions of L-Carnitine include increasing mitochondrial energy production, helping in burning fat and combating brain fatigue.
  • L-Phenylalanine: L-Phenylalanine is a very important essential amino acid that is present in various foods. It has been seen that activation of CREB is followed by increased transcription of enzyme tyrosine hydroxylase which leads to increased dopamine metabolism rates. L-Phenylalanine serves as a natural precursor to the dopamine which helps in supplying necessary amino acid fuel to aid in that metabolism.
  • Vitamin B6: The essential Vitamin B6 serves as a vital enzymatic cofactor helping in the production of essential neurotransmitters such as serotonin, dopamine, and GABA. The vitamin helps to activate the enzyme DOPA decarboxylase which is produced in dopamine metabolism from tyrosine hydroxylase. It helps to keep the optimal balance of dopamine metabolism under increased Tyrosine Hydroxylase occurring during the process of CREB enhanced LTP.

Does CILTEP Have Any Side Effects?

Some people have experienced initial hints of nausea which can occur due to increased portions of PDE4 inhibitors in the body. Another side effect that has been reported is insomnia that can occur if the capsules are taken along with too much caffeine intake. L-phenylalanine supplementation can cause headaches and jitters in some people. Individuals having Parkinson’s disease and schizophrenia might develop certain other negative symptoms while taking phenylalanine. A number of people have also experienced a slight crash following the intake of CILTEP capsules. Other effects include reduced choline levels and drowsiness.
