HOW IT WORKS
THE SECRET NEURO-PATHWAY
FOR A BETTER BRAIN
Scientists estimate there are over 100 trillion connection points aka synapses in the human brain.
When you’re trying to remember something or solve a problem, your neurotransmitters (the pink dots) are signaling between your brain cells.
The signal transmission must be STRONG in order for the information to fully transfer.
If this signal is weak...
It can leave you scratching your head wondering why you walked into the room or struggling to remember someone's name even though you've met them many times before!
But that's where NEUROFUEL™ comes in.
The formula contains five of the purest natural ingredients on the planet... and while powerful on their own...
It's the combination that can boost an important brain function known as Long-Term Potentiation (aka LTP for short).
LTP is a crucial mechanism involved in the formation new memories and the strengthening of synapses.
By increasing LTP, you can:

NEUROFUEL™ PATENTED FORMULA
Artichoke extract contains Luteolin, a safe, natural inhibitor of PDE4.
PDE4 inhibitors have been shown to have significant nootropic effects including increased cognition, improved long term memory, increased wakefulness, and are also neuroprotective.
Coleus Forskohlii activates the enzyme adenylyl cyclase which increases intracellular levels of cAMP.
The result is an overall improvement of cognitive function, especially memory formation and retention of new information.
Known for its roles in energy metabolism and mitochondrial protection, the addition of ALCAR to the NeuroFuel formula helps combat feelings of brain fog and fatigue. [15,16]
L-Phenylalanine is an essential amino acid found in some foods that the brain uses to make dopamine.
This amino acid acts as fuel to support efficient dopamine metabolism for maximum motivation and a positive mood.
Vitamin B6 is an essential vitamin and an important enzymatic cofactor in normal metabolic and psychological function. 
NEUROFUEL™ features the metabolically active form of Vitamin B6 (Pyridoxal-5-Phosphate) for optimal bioavailability.
A FORMULA SO POWERFUL IT'S PATENTED
Did you know it's very rare for a natural supplement to receive a patent? It has to be powerful, effective and research-backed.
NEUROFUEL™ checks all of the boxes.
The United States Patent and Trademark Office is known to be the most stringent in the world.
NEUROFUEL™ has met their high standards as a "nutritional supplement for increasing cognitive function".

Take 1-3 capsules in the morning immediately upon waking on an empty stomach. Do not take more than 3 capsules per day.
Some users find that a moderate dose of caffeine in the morning and/or early afternoon extends and optimizes results.
NEUROFUEL™ can be taken daily, however we advise taking 1-2 days off per week (weekends for example).
U.S.A manufactured in a GMP facility. NeuroFuel™ is protected by U.S. Patents US10058529B2 and US9149457B2.
We suggest taking NEUROFUEL™ first thing in the morning on days that include demanding cognitive tasks. Take it on an empty stomach and 20-30 minutes later, you eat breakfast or - our favorite, have some bulletproof coffee for an extra spark.
NEUROFUEL™ increases focus and potentiates long-term memory but doesn't rely on neurotransmitter manipulation to elicit this benefit. Because NEUROFUEL™ is not a stimulant and it doesn’t directly impact our neurotransmitters, the “feel” is very subtle.
What you notice most is that time seems to slow, distractions fade away (increased focus), and you have a strong desire to learn/read/work.The more mentally demanding the task, the more NEUROFUEL™ shines.
Many users prefer to “stack” or combine NEUROFUEL™ with one of our Brain Food products. The Brain Food line is designed to give individuals the tools needed to optimize whatever neurotransmitter they may need to moderate on any given day or at any given time.
NEUROFUEL™ is a natural nutritional supplement designed for improving and maintaining brain performance. It's theorized to improve learning and memory in the brain by supporting and optimizing levels of intracellular secondary messengers.
There are no known side effects if used as directed. For that reason, thousands of people have chosen all-natural NEUROFUEL™ as their preferred nootropic stack.
No you do not have to cycle NEUROFUEL™. Normally people take 2-3 capsules during the work week and then off on the weekends.
CILTEP® (sil-tep) is a nootropic stack or smart drug used to improve mental performance.It was developed in 2012 by world renowned biohacker Abelard Lindsay, patented and then licensed exclusively to Natural Stacks. In 2020, Natural Stacks changed the name of CILTEP® to NEUROFUEL™. The same powerful, patented formula remains the same but it's now available at a new lower price.
Yes. It's all-natural, vegan, soy-free and paleo.
NEUROFUEL™ works best on an empty stomach. You'll feel the fuel fast, within 30 minutes of your first dose. Due to the effects it's recommended to take NEUROFUEL™ during the daytime or early afternoon.
The formula works by: PDE4 Inhibition + Increasing cAMP = Long-Term Potentiation
Developed by Abelard Research, the NEUROFUEL™ Formula is a protected by United States Patent and Trademark Office US9149457B2.
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. [3,4,5,6,7,8]
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. [1,2]Artichoke Extract is a safe, effective and natural PDE4 Inhibitor. [1,2]
NEUROFUEL™ contains 900 mg of the highest quality Artichoke Extract in each serving.
The herb 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. 
Neuro Fuel™ 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
NEUROFUEL™ uses a simple, all-natural formula that works by increasing the number of messenger systems inside of your brain cells. This enables neurons to quickly communicate with each other and retain information. It makes you more engaged and efficient at whatever mental task you might be doing.
NEUROFUEL™ enhances your mental capacity without relying on altering neurotransmitter levels. It acts inside of the cell to naturally strengthen connections between neurons, promoting improved learning, memory, and cognitive function.
