Learn More About Noopept

Noopept is an elite Nootropic which produces unparalleled effects. Noopept revitalizes neuroprotective processes[2] in the user through the stimulation of the essential proteins Nerve Growth Factor (NGF) and Brain Derived Neurotrophic Factor (BDNF).[1] NGF assumes a vital role in neuronal development, neuronal survival, and neuronal regeneration. BDNF connects to receptors in the synapses among neurons that result in increased electrical power and more effective signaling between neurons. BDNF enables new neurons to branch out, while at the same time preventing degradation of existing neurons. The synapses in which BDNF bind to will change and adapt with time, in response to experience, an attribute known as synaptic plasticity. BDNF helps regulate synaptic plasticity, which is critical for learning and memory.

At the same time, Noopept stimulates the AMPA[3] and NMDA receptors as well as their pathways. AMPA receptors are responsible for most of the fast excitatory synaptic transmission which allows for memories to be retrieved. Stimulation of NMDA receptors is imperative for controlling synaptic plasticity and memory function. Long Term Potentiation (LTP), implicated as a primary mechanism behind learning and memory, occurs after AMPA and NMDA receptor stimulation that can be induced by Noopept. Furthermore, LTP is a primary mechanism which underlies learning and memory. Noopept leads to increased communication between the two hemispheres of the brain. This is hypothesized to improve language fluidity and the synthesis of abstract ideas. Also, Noopept possesses anxiolytic properties due to its activation of the dopamine receptors: D2 and D3. These receptors are associated with not only reward and reinforcement mechanisms, but also the working memory. Lastly, Noopept induces a sensitizing effect of acetylcholine (ACh) processes, while also stimulating the delivery of ACh to neurons. ACh is a neurotransmitter that prompts sustained attention[4], enhancement of sensory perceptions[5], and responsiveness to sensory stimuli. With supplementation of a high-quality choline source, such as CDP Choline, Noopept will induce significant cognitive enhancement. In short, Noopept is a powerful nootropic which delivers increased cognitive function through multiple mechanisms.

Learn More About Citicoline

CDP Choline is a nootropic compound which plays an important role in cellular metabolism. After ingestion, CDP Choline is hydrolyzed into choline and cytidine. Cytidine will then be converted to uridine. The choline and uridine will pass through the blood-brain barrier and turn back into CDP Choline. CDP choline simultaneously increases ACh synthesis and enhances signaling of ACh receptors. ACh is a neurotransmitter that induces sustained attention[4], enhancement of sensory perceptions[5], and responsiveness to sensory stimuli. Studies have concluded that CDP Choline supplementation can improve attention as well as improve memory retention at doses of 250-500 mg.[16] Another noteworthy benefit of CDP Choline is the production of increased levels of Phosphatidylcholine (PC).[18][19][20] PC forms part of brain cell membranes and is responsible for membrane-mediated cell signaling. The highlight of PC is its ability to act as a choline reservoir from which ACh can be discharged when necessary.[21] Additionally, CDP Choline helps to restore phospholipid levels, specifically cardiolipin[22] and sphingomyelin. Cardiolipin is an important component of the inner mitochondrial membrane. It is essential for the optimal function of numerous enzymes that are involved in mitochondrial energy metabolism and is responsible for importing proteins into the mitochondrial matrix. Sphingomyelin is found in the membranes myelin sheath that surrounds some nerve cell axons. Sphingomyelin, therefore, acts as an insulator of nerve fibers as well as an activator of universal signaling pathways. CDP Choline also stimulates glutathione (GSH), a key antioxidant that promotes neuroprotective properties.

CDP Choline not only enhances dopaminergic signaling but also increases dopamine receptor site density.[17] Dopamine is most responsible for cognitive alertness. Norepinephrine, another neurotransmitter stimulated by CDP Choline, is most responsible for vigilant concentration. The noradrenergic neurons originate in the Locus Coeruleus, located in the brain stem. Several studies have implicated the LC-NE system in eliciting the P300, a cortical event related potential that responds to environmental stimuli with behaviorally relevant, motivational, or attention grabbing properties. The P300 may reflect updating of prior knowledge regarding stimuli for accurate and efficient decision making. Lastly, CDP Choline increases cerebral blood flow.[23]

The benefits of Bacopa Monnieri supplementation are far reaching and very well documented. A powerful benefit triggered by Bacopa Monnieri is the proliferation of dendritic Intersections caused by the growth of nerve endings.[7] In other words, when more neural pathways cross, the result is more efficient processing of Information input (learning) and easier recall of information stored (memory).[8] This benefit has been noted in animal studies after 4-6 weeks of supplementation. The nerve ending growth, stimulated by Bacopa Monnieri, directly results in enhanced neuronal communication. In studies, Bacopa Monnieri has proven to boost the memory of learned material as well as increase retention speed.[9] The method by which Bacopa Monnieri improves memory formation is via the enzyme Tryptophan Hydroxylase (TPHZ) and heightening serotonin transporter (SERT) expression.[6] Another benefit associated with Bacopa Monnieri supplementation is increased cerebral blood flow.[15] Bacopa Monnieri is a known adaptogen capable of alleviating stress when pre-loaded.[10] Bacopa Monnieri supplementation has been found to lower levels of HSP70 (a stress biomarker) in all areas of the brain, especially the hippocampus. It is believed Bacopa Monnieri provokes the stress response, preparing the brain to better manage perceived stress.[11] Furthermore, it has been noted that during times of chronic stress Bacopa Monnieri supplementation prevents the reduction of dopamine and serotonin levels.[12] A study using 320 mg of Bacopa Monnieri extract proved to increase performance in a cognitive demand battery test.[13] The results showed an extended consistency of cognitive performance. Bacopa Monnieri certainly offers significant antioxidant effects as well. In animal studies, Bacopa Monnieri causes raised levels of Superoxide Dismutase (SOD) and Glutathione Peroxidase after three weeks of supplementation.[14] The levels were raised in various brain regions including the hippocampus, Frontal cortex, and striatum. Superoxide Dismutase detoxifies Superoxide, in turn preventing attacks on enzymes and DNA mutation, while Glutathione Peroxidase provides protection from oxidative damage.

Learn More About Sulbutiamine

Sulbutiamine is a synthetic variant of thiamine (Vitamin B1), composed of two B1 molecules bound together, which crosses the brain blood barrier with ease. The metabolism of Sulbutiamine in the brain increases levels of thiamine. Sulbutiamine is currently hypothesized to be upregulated through the Reticular Activating System (RAS) in the brain.[27] The RAS mediates transitions from periods of relaxed wakefulness to high attention. One result of Sulbutiamine supplementation is the potentiation of cholinergic activity in the hippocampus. The hippocampus is responsible for consolidating short and long term memory, spatial navigation, as well as casting meaning on one’s experiences. In one study, upon administration of Sulbutiamine, mice displayed greater retention of memory.[25] Another benefit associated with Sulbutiamine is the potentiation of glutamatergic activity in the prefrontal cortex, delivering increased memory function.[24] Increased glutamatergic transmission through the cingulate and prefrontal cortices, credited with influencing decision organization and strategy has been observed from Sulbutiamine supplementation. Furthermore, Sulbutiamine increases dopamine D1 receptor site density, which causes neuronal growth.[28] In other studies utilizing Sulbutiamine, mice were able to score better on operant conditioning and object recognition tests.[25] Sulbutiamine increases the availability of THTP, directly contributing to the phosphorylation of proteins and activation of high conductance chloride channels.[30] Thiamine Triphosphate (THTP), an integral component of synaptosomal membranes, plays an important role in cell energy metabolism.[29] Sulbutiamine has been used to treat chronic fatigue, returning strong results in a study of 58 patients with  Multiple Sclerosis (MS).The improvement was noted regarding fatigue in 91.37% of persons tested.[26] Sulbutiamine has even been shown to increase visual acuity.

Caffeine and L-Theanine are highly synergistic and result in improvements in sustained attention, reaction time, and task switching. While caffeine alone can make task switching difficult even when the occupying stimulus is not the priority.

Learn More About Caffeine

Caffeine is a stimulant of the Central Nervous System (CNS) which is consumed by 87% of the U.S. population daily. After oral ingestion, caffeine is 100% absorbed within 45 minutes. It is widely known that caffeine consumption causes increased alertness and wakefulness. This is the case for even those consumers who have been deprived of sleep. Caffeine inhibits the molecule adenosine from binding to adenosine receptors effectively raising levels of serotonin and causing nerve cells to speed up and increase neuron firing, thereby preventing lethargy and enhancing mood.[37, 38] Due to this increase in neural activity, additional adrenaline is produced resulting in extra energy. Caffeine alters dopamine levels by slowing the rate of dopamine reabsorption. The neurotransmitter dopamine is most responsible for cognitive alertness, therefore increased dopamine levels would allow for one to be more receptive of stimuli in their environment.

Caffeine also increases acetylcholine levels, specifically in the medial prefrontal cortex, resulting in attention promoting qualities.[39] In a study where participants consumed 3.5 mg/kg of caffeine, while under psychological stress, it was found that adrenaline release was enhanced by 233% in response.[40] Caffeine and L-Theanine are a highly synergistic combination which has been extensively studied. Studies have indicated major improvements in sustaining attention, reaction time, and task switching.[41] The relaxing properties of L-Theanine eliminate the distracting stimuli often experienced from caffeine consumption.[42]

The relaxing properties of  L-Theanine eliminate the distracting stimuli often experienced from caffeine consumption.

Learn More About L-Theanine

L-Theanine is a non-proteinogenic amino acid found primarily in green tea. Since L-Theanine is less bioavailable when consumed through green tea, better results are experienced from L-Theanine supplements. After oral ingestion of L-Theanine, it crosses the brain blood barrier intact and elevates L-Theanine levels for up to five hours.[43] Increased levels of L-Theanine in the brain have been specifically noted in the hippocampus one hour following oral ingestion.[44] L-Theanine’s most profound benefit is its ability to induce relaxation without sedation. This is in part due to raised levels of the neurotransmitter GABA caused by L-Theanine.[46] GABA is the primary inhibitory neurochemical in the brain which prevents excessive neuronal firing to effectively create a calm state of mind. Persons consuming a 200 mg dose during a study, of which had high baseline anxiety levels, reported anxiety relief as well as improvement in attention.[45] In another study supplementing 200 mg of L-Theanine before a stressful task resulted in a reduction of perceived stress noted by participants.[47] L-Theanine supplementation is also accredited with increasing alpha brain-wave patterns which are associated with relaxation, selective attention mechanisms, and mental alertness.[45]. L-Theanine also increases levels of dopamine and serotonin thus influencing an enhanced mood. Additionally, L-Theanine has proven to enhance vascular responsiveness and promote nitric oxide formation.[48][49] Nitric oxide signals smooth muscles to relax, leading to vasodilatation and increased blood flow. L-Theanine and caffeine are a highly synergistic combination that has been extensively studied. Studies have indicated major improvements in sustained attention, reaction time, and task switching.[41] The relaxing properties of L-Theanine eliminate the distracting stimuli often experienced from caffeine consumption.[42]

Vitamin D3 is 1 of 24 micronutrients critical for human survival associated with increased cognition, immune health, bone health, and wellbeing. 1700 IU daily supplementation is needed to achieve the optimal D3 level for 95 percent of the population. D3 confers a protective effect from excitotoxicity induced neuronal cell death while also preserving neuronal cells.[55][56] Furthermore, vitamin D3 blood levels are inversely correlated with depressive symptoms. One study noted an attenuation of depressive symptoms with dosing of 4000 IU daily for one month followed by 2000 IU daily for two more months. The beneficial results were universal among all 54 participants.[57] Vitamin D3 produces significant benefits regarding mood and wellbeing due to increasing serotonin synthesis. Serotonin is synthesized from tryptophan by tryptophan hydroxylase 2, which is transcriptionally activated by vitamin D. During experiments conducted using synthesized DNA vitamin D enhanced the ability of brain cells to produce serotonin anywhere from 2 to 30 times as much.[58] Serotonin has very specific effects on cognition including executive function, learning memory, and relaxation.
