Warning:
Do not consume nicotine or prescription stimulants with CILTEP. Do not use if pregnant, nursing, or under the age of 18. Consult with a healthcare practitioner before taking this or any nutritional supplement if you'll have or suspect a medical condition or take any medications.

"Nootropic" is the term for supplements that are said to improve our mental abilities such as concentration and memory. CILTEP is included in this category and has quickly become very popular around the world. It is also unique in being fully permitted in Sweden, unlike several other known nootropics.

Function
The development of CILTEP was inspired by Nobel Prize winner Eric Kandel's work. He discovered how synapses efficacy can be changed and which molecular mechanisms that are involved in this. Kandel also showed how synaptic function are central for memory and learning. One of Kandel's discoveries showes how the molecular building block cAMP (cyclic adenosine monophosphate) plays a central role in the formation of memories. cAMP acts as a second messenger for several neurotransmitters and hormones inside the cells. cAMP is degraded by the enzyme phosphodiesterase type 4 (PDE4).
Kandel's research team got astounding results when they managed to medically prevent PDE4s breakdown of cAMP in mice. The mice suddenly began to navigate faster in the mazes (1). This was the start that made PDE4 inhibitors to a new research area where one could observe everything from better memory (2) and neuron-protective effect (3) (4), increased alertness (5) and anti-inflammatory properties (6). The ability to treat a variety of brain-related disorders have also been investigated (7).
The idea behind CILTEP was to produce an optimal combination of natural ingredients that inhibit PDE4 and prolongs the time that cAMP is present in the cells. cAMP activates a protein called CREB, which has a well-documented role in the plasticity of the brain cells and the formation of long term memory (8). CREB is important for so-called Long-term potentiation (LTP) (9), which is the persistent strengthening of simultaneous activation of the synapses in the brain. This is considered by many to be physiologically essential in creating memories. The word CILTEP is short for Chemically Induced Long term potentiation.
Ingredients:
Artichoke extract contains the substance luteolin (10) that has been shown to act as effective inhibitors of PDE4 (11). It also inhibits PDE type 1 to 5, which has been shown to promote synaptic plasticity and memory (12) (13).
Forskolin is produced from the plant Makandi and has long been used in traditional Ayurvedic medicine. The topic has been studied comprehensively in modern research and it has been shown effective in increase the levels of cAMP in the cells (14). Forskolin is paired with luteolinet to work together for a stronger effect.
L-Phenylalanine is an essential amino acid and a natural precursor to dopamine. When CREB is activated, cells increase their dopamine metabolism trough the activation of the enzyme tyrosine hydroxylase (15). L-phenylalanine is added to provide necessary fuel.
Vitamin B6 is required for the conversion of L-fenylalnin into dopamine. The substance is included in the "stack" to achieve the optimal dopamine levels in the higher turn-over during the CREB-enabled LTP.
Acetyl L-carnitine is a form of the amino acid L-carnitine. Both are found in food and can be produced by the liver. Acetyl L-carnitine has been shown to increase levels of the neurotransmitter acetylcholine in the brain (16). cAMP activated forskolin increases the levels of the enzyme acetylcholinesterase (17), which breaks down acetylcholine. Acetyl-l-carnitine has therefor been added to counteract this and can theoretically provide increased energy and better short-term memory.
