Neurofuel Helps Beat Brain Fog*

Brain Fog is the worst! We all have those moments where it’s just impossible to focus, or when the one thing we were thinking of is just stuck at the tip of the tongue.  As we get older these things tend to get worse, but the good news is they don’t have to. There’s a reason why thousands around the world are using Neurofuel to boost their focus, motivation and memory.*

Neurofuel Unique Ingredients

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

Neurofuel for Focus and Memory

A natural supplement that can help you achieve a higher state of focus and concentration with enhanced memory formation.*

The formula is designed to induce long-term potentiation (LTP) in the brain.*

LTP is a crucial mechanism involved in the formation of new memories and the strengthening of neural synapses.*

The Neurofuel formula works by:

PDE4 Inhibition + Increasing cAMP = Long-Term Potentiation*

Developed by Abelard Research, the CILTEP® Formula is a protected by United States Patent and Trademark Office US9149457B2. Natural Stacks is currently involved in multiple placebo-controlled, double-blind University studies on its effectiveness.


PDE4 is an enzyme that breaks down cAMP molecules, messenger systems that relay signals in the brain. Inhibition of PDE4 blocks the breakdown of cAMP, and thereby increases levels of cAMP within brain cells.  This has been shown to lead to increased cognition, improved long term memory, increased wakefulness, and neuroprotection.*†

There have been several natural PDE4 inhibitors identified in herbal preparations including luteolin, which is present in artichoke extract. It also inhibits PDE 1 through 5 which have both shown beneficial activity with regards to synaptic plasticity.  Artichoke Extract is a safe, effective and natural PDE4 Inhibitor.  CILTEP contains 900 mg of the highest quality Artichoke Extract in each serving.*†


Forskolin (active compound extracted from the root of the Coleus Forskohlii plant) has been shown to naturally increase cAMP levels.  It activates the enzyme adenylyl cyclase which then increases intracellular levels of cAMP. CILTEP features premium Coleus Forskohlii standardized for 20% Forskolin. There are 4 mg of Forskolin in each serving of CILTEP.  Increasing cAMP and inhibiting its degradation supports Long-Term Potentiation (LTP).*†

Summary: PDE4 Inhibition + Increasing cAMP → LTP → Supports optimal mental performance.*†
