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 of entrepreneurs, doctors, firefighters and students around the world are using CILTEP® to boost their focus, motivation and memory. 

Introducing CILTEP® (sil-tep) for Focus and Memory

CILTEP® is 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 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 INHIBITION

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] CILTEP contains 900 mg of the highest quality Artichoke Extract in each serving.

INCREASING cAMP

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. [10]

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

02/ Ingredients

Artichoke Extract(900 mg)

Artichoke extract contains Luteolin, a natural inhibitor of PDE4 [1,2]. PDE4 is an enzyme that breaks down cAMP molecules, messenger systems that relay signals in the brain. Studies have correlated lower levels of the enzyme PDE4 to significant increases in normal mental performance, including increased cognition [3], improved long term memory [4], increased wakefulness [5], and neuroprotection. [6,7,8]

03/ Suggested Use

Take 1-3 capsules in the morning immediately upon waking on an empty stomach, or as directed by a healthcare practitioner. 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 (We recommend SMART CAFFEINE®).

CILTEP® can be taken daily, however we advise taking 1-2 days off per week (weekends for example).

Memory has improved using CILTEP

At 48 I noticed a growing difference in my focus and memory. Other supplements were not improving the situation. However within 2 weeks of taking 2 CILTEP capsules each morning, 30 mins before any food I feel confident that my cognitive performance is better. 3 capsules was too many as it caused some jitters.
