Fuel for your brain

When is Neurofuel™ suitable? We all know situations when we need more focus, want to concentrate more fully, or think more clearly. Sometimes we have complex problems to solve or important goals to achieve. Some people also suffer from what is known as brain fog or simply a lack of motivation. As we get older, this can happen more and more often. We can all use a little push from time to time. Neurofuel™ is a 100% natural formula for better brain performance.

How does it work?

Take two capsules of Neurofuel™ on an empty stomach, for example before work or a situation requiring focus. Thirty minutes later you can feel the fuel going to work. Neurofuel™ provides the body with the natural ingredients it needs in the moment. CILTEP® is widely popular with business people, students, athletes, scientists and creative minds, among others. In addition to the immediate tangible effects, it also has long-term effects. In general, users experience effects shortly after ingestion but they can last for 8 to 14 hours.

Long-term effect

The long-term action of Neurofuel™ is known as Long-Term Potentiation, or LPT. LPT is a long-term enhancement of signal transmission between two neurons in the brain. It is one of the most important cellular mechanisms behind learning and memory. The ingredients in this formula work in close unison. They inhibit a substance called PDE4. PDE4 blocks the breakdown of a substance called cAMP, thus increasing cAMP content in brain cells. This process results in LPT and produces significant nootropic effects. It also renders dopamine metabolism more effective.

The CILTEP® formula

Neurofuel™, or the original CILTEP® formula, contains 5 ingredients that reinforce each other and work together in a natural way.

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

Vitamin B6

Neurofuel™ contains vitamin B6 in the form of pyridoxal-5-phosphate, or P5P. P5P is the biologically active form of Vitamin B6. The vitamin no longer needs to be converted by the body, a process not equally efficient for everyone. The body can therefore use it immediately. Vitamin B6 is an essential vitamin and an important enzymatic cofactor for normal metabolic and psychological functioning. In the brain Vitamin B6 is used as a cofactor in the production of neurotransmitters dopamine, GABA and serotonin. Vitamin B6, for example, helps convert the precursor L-DOPA into active dopamine.

Artichoke extract

The second ingredient of Neurofuel™ is artichoke extract. Artichoke extract (Cynara scolymus) is an extract from the artichoke vegetable bulb. It enjoys several health claims still awaiting approval by the European Commission. It also contains luteolin, which plays a role in the enzyme PDE4 as well as LPT. 

Forskolin extract

The third ingredient of Neurofuel™ is forskolin extract from the beneficial plant Coleus Forskohlii. This is a naturally rich source of the substance forskolin, which shows a unique biological activity. Forskolin helps activate certain enzymes and plays a role in the metabolism of cAMP molecules and LPT. Forskolin is widely used in Ayurveda.

L-phenylalanine and acetyl-L-carnitine

Finally, Neurofuel™ contains two more amino acids: L-phenylalanine and acetyl-L-carnitine. L-phenylalanine is an essential building block for the neurotransmitter dopamine. It is an essential amino acid found in protein foods such as meat, eggs, spinach and other leafy greens.

Acetyl-L-Carnitine, or ALCAR, is an acetylated form of the amino acid L-Carnitine known to move well throughout the body. It plays a role in energy metabolism and mitochondrial function. In addition to the CILTEP formula, it show a synergistic effect with the other ingredients.

Cautionary note

Do not combine CILTEP® with other stimulants, as CILTEP® can enhance their effect. CILTEP® may be combined with the product Smart Caffeine from Natural Stacks. Depending on the tolerance, 100-200 mg of caffeine offer optimal results. Do not use this product if you have PKU (Phenylketonuria) disease.
