“Dietary CDP-choline supplementation prevents memory impairment caused by impoverished environmental conditions in rats.”

Results: These findings indicate that long-term dietary CDP-choline supplementation can ameliorate the hippocampal-dependent memory impairment caused by impoverished environmental conditions in rats, and suggest that its actions result, in part, from a long-term effect such as enhanced membrane phosphatide synthesis, an effect shown to require long-term dietary supplementation with CDP-choline.

“Short-term administration of uridine increases brain membrane phospholipid precursors in healthy adults: a 31-phosphorus magnetic resonance spectroscopy study at 4T.”

Results: This is the first study to report a direct effect of uridine on membrane phospholipid precursors in healthy adults using (31) P-MRS. Sustained administration of uridine appears to increase PME in healthy subjects. Further investigation is required to clarify the effects of uridine in disorders with altered phospholipid metabolism such as bipolar disorder.

(ALCAR) 333mg
Acetyl L-Carnitine

An amino acid that is naturally produced in the body which helps produce energy and can help increase energy production in the mitochondria. This acetylated version of carnitine is able to cross the blood-brain barrier. Its primary effect is on the production of acetylcholine which is one of the main neurotransmitters involved in memory, learning, computation, analysis and many other cognitive processes.†

“Dietary supplementation with acetyl-l-carnitine counteracts age-related alterations of mitochondrial biogenesis, dynamics and antioxidant defenses in brain of old rats.”

Results: Overall, our findings indicate a systemic positive effect of ALCAR dietary treatment and a tissue specific regulation of mitochondrial homeostasis in brain of old rats. Moreover, it appears that ALCAR acts as a nutrient since in most cases its effects were almost completely abolished one month after treatment suspension. Dietary supplementation of old rats with this compound seems a valuable approach to prevent age-related mitochondrial dysfunction and might ultimately represent a strategy to delay age-associated negative consequences in mitochondrial homeostasis.

“L-Carnitine and Acetyl-L-carnitine Roles and Neuroprotection in Developing Brain.”

Results: There is compelling evidence from preclinical studies that L-carnitine and ALCAR can improve energy status, decrease oxidative stress and prevent subsequent cell death in models of adult, neonatal and pediatric brain injury. ALCAR can provide an acetyl moiety that can be oxidized for energy, used as a precursor for acetylcholine, or incorporated into glutamate, glutamine and GABA, or into lipids for myelination and cell growth. Administration of ALCAR after brain injury in rat pups improved long-term functional outcomes, including memory. Additional studies are needed to better explore the potential of L-carnitine and ALCAR for protection of developing brain as there is an urgent need for therapies that can improve outcome after neonatal and pediatric brain injury.

“Chronic acetyl-L-carnitine alters brain energy metabolism and increases noradrenaline and serotonin content in healthy mice.”

Results: These findings are consistent with decreased metabolism of glucose to lactate but not via the TCA cycle. Higher amounts of the sum of adenosine nucleotides, phosphocreatine and the phosphocreatine/creatine ratio found in the cortex of ALCAR-treated mice are indicative of increased energy levels. Furthermore, ALCAR supplementation increased the levels of the neurotransmitters noradrenaline in the HF and serotonin in cortex, consistent with ALCAR’s potential efficacy for depressive symptoms. Other ALCAR-induced changes observed included reduced amounts of GABA in the HF and increased myo-inositol. In conclusion, chronic ALCAR supplementation decreased glucose metabolism to lactate, resulted in increased energy metabolite and altered monoamine neurotransmitter levels in the mouse brain.

LION'S MANE

Hericium Erinaceus (also called Lion's Mane) is an edible and medicinal mushroom. Lion's Mane can induce Nerve Growth Factor synthesis in nerve cells which is essential for the maintenance of the basal forebrain cholinergic system. A double-blind placebo-controlled clinical trial study showed increased cognitive function scores for people who took Lion's Mane vs a placebo group. †

“Neurotrophic properties of the Lion's mane medicinal mushroom, Hericium erinaceus (Higher Basidiomycetes) from Malaysia"

Results: The extract contained neuroactive compounds that induced the secretion of extracellular NGF in NG108-15 cells, thereby promoting neurite outgrowth activity. However, the H. erinaceus extract failed to protect NG108-15 cells subjected to oxidative stress when applied in pre-treatment and co-treatment modes. In conclusion, the aqueous extract of H. erinaceus contained neuroactive compounds which induced NGF-synthesis and promoted neurite outgrowth in NG108-15 cells. The extract also enhanced the neurite outgrowth stimulation activity of NGF when applied in combination. The aqueous preparation of H. erinaceus had neurotrophic but not neuroprotective activities.

Results: Intriguingly other neurobiological effects have recently been reported like the effect on neurite outgrowth and differentiation in PC12 cells. Until now no investigations have been conducted to assess the impact of this dietary supplementation on brain function in healthy subjects. Therefore, we have faced the problem by considering the effect on cognitive skills and on hippocampal neurotransmission in wild-type mice. In wild-type mice the oral supplementation with H. erinaceus induces, in behaviour test, a significant improvement in the recognition memory and, in hippocampal slices, an increase in spontaneous and evoked excitatory synaptic current in mossy fiber-CA3 synapse. In conclusion, we have produced a series of findings in support of the concept that H. erinaceus induces a boost effect onto neuronal functions also in non-pathological conditions.

“Soybean-derived phosphatidylserine improves memory function of the elderly Japanese subjects with memory complaints.”

Results: As a result, there was no difference in blood markers and vital signs during Soy-PS treatment and any side effect caused by Soy-PS treatment was not observed. Neuropsychological test scores were similarly increased in all groups including placebo group. However, in the subjects with relatively low score at baseline, the memory scores in PS treated groups were significantly increased against the baseline, while those of placebo group remained unchanged. And the memory improvements in Soy-PS-treated groups were mostly attributed to the increase in delayed verbal recall, a memory ability attenuated in the earliest stage of dementia. In conclusion, Soy-PS used in this study is considered as safety food ingredient and 6 months of Soy-PS supplementation could improve the memory functions of the elderly with memory complaints.

Results: Chronic stress levels and other baseline measures did not differ between treatment groups (all p > 0.05). Acute stress was successfully induced by the TSST and resulted in a hyper-responsivity of the HPAA in chronically stressed subjects. Compared to placebo, a supplementation with a daily dose of PAS 400 was effective in normalizing the ACTH (p = 0.010), salivary (p = 0.043) and serum cortisol responses (p = 0.035) to the TSST in chronically high but not in low stressed subjects (all p > 0.05). Compared to placebo, supplementation with PAS 200 did not result in any significant differences in these variables (all p > 0.05). There were no significant effects of supplementation with PAS on heart rate, pulse transit time, or psychological stress response (all p > 0.05).

“Effects of soy lecithin phosphatidic acid and phosphatidylserine complex (PAS) on the endocrine and psychological responses to mental stress.”

Results: Treatment with 400 mg PAS resulted in a pronounced blunting of both serum ACTH and cortisol, and salivary cortisol responses to the TSST, but did not affect heart rate. The effect was not seen with larger doses of PAS. With regard to the psychological response, 400 mg PAS seemed to exert a specific positive effect on emotional responses to the TSST. While the placebo group showed the expected increase in distress after the test, the group treated with 400 mg PAS showed decreased distress. These data provide initial evidence for a selective stress dampening effect of PAS on the pituitary-adrenal axis, suggesting the potential of PAS in the treatment of stress related disorders.

(DMAE Bitartrate) 58mg
DIMETHYLAMINOETHANOL

DMAE is a precursor to acetylcholine, which is one of the main memory-forming neurotransmitters in your brain. Higher acetylcholine levels have been linked with better performance on some memory tests.† As a nootropic, it is closely related to choline but due to a slightly different chemical structure it crosses the blood-brain barrier differently.†

“Effects of dimethylaminoethanol pyroglutamate (DMAE p-Glu) against memory deficits induced by scopolamine: evidence from preclinical and clinical studies.”

Results: In rat experiments, DMAE p-Glu increased the extracellular levels of choline and acetylcholine in the medial prefrontal cortex, as assessed by intracerebral microdialysis, improved performance in a test of spatial memory, and reduced scopolamine-induced memory deficit in passive avoidance behavior. Clinical study results show that scopolamine induced a memory deficit and that DMAE p-Glu produced a significant positive effect on scores in the Buschke test, as well as a slight but significant difference on choice reaction time.

“People are different: tyrosine's modulating effect on cognitive control in healthy humans may depend on individual differences related to dopamine function.”

Results: Therefore, these findings have two interesting implications for studies on TYR. First, the higher TH transcription activity associated with the T allele in the C-824T polymorphism could mean that low baseline DA individuals who carry this allele can benefit especially from TYR supplementation, as more TYR can be converted into DA. Second, the idea that the T allele protects against cognitive decline in schizophrenia could imply that it does so in old age as well. In that case, the effect of this polymorphism on TYR supplementation might be strongest in older individuals, as might be the case with the DRD2 gene. This possibility again underscores the need to keep age and age-related changes in neurophysiology in mind when investigating TYR.

(NAC)100mg
N-ACETYL CYSTEINE

N-acetyl cysteine (sometimes refered to as NAC) comes from the amino acid L-cysteine, that has been known as a strong antioxidant and one of the few supplements to help combat hangover symptoms from Alcohol.†

“Intravenous Administration of Stable-Labeled N-Acetylcysteine Demonstrates an Indirect Mechanism for Boosting Glutathione and Improving Redox Status.”

Results: Molar ratios of the reduced and oxidized forms of GSH (GSH divided by glutathione disulfide, redox ratio) were also determined. The elimination phase half-life of NAC was approximately 34 min. Both labeled and unlabeled GSH in RBC were found to increase; however, the area under the curve above baseline (AUCb0-280 ) of labeled GSH was only 1% of the unlabeled form. These data indicate that NAC is not a direct precursor of GSH. In addition, NAC has prolonged effects in brain even when the drug has been eliminated from systemic circulation.

“N-acetylcysteine amide confers neuroprotection, improves bioenergetics and behavioral outcome following TBI.”

Results: The current study evaluated a novel, cell permeant amide form of N-acetylcysteine (NACA), which has high permeability through cellular and mitochondrial membranes resulting in increased CNS bioavailability. Cortical tissue sparing, cognitive function and oxidative stress markers were assessed in rats treated with NACA, NAC, or vehicle following a TBI. At 15 days post-injury, animals treated with NACA demonstrated significant improvements in cognitive function and cortical tissue sparing compared to NAC or vehicle treated animals. NACA treatment also was shown to reduce oxidative damage (HNE levels) at 7 days post-injury. Mechanistically, post-injury NACA administration was demonstrated to maintain levels of mitochondrial glutathione and mitochondrial bioenergetics comparable to sham animals. Collectively these data provide a basic platform to consider NACA as a novel therapeutic agent for treatment of TBI.

“Social isolation rearing induces mitochondrial, immunological, neurochemical and behavioural deficits in rats, and is reversed by clozapine or N-acetyl cysteine.”

Results: Clozapine+NAC was more effective than clozapine alone in reversing SIR-induced PPI, mitochondrial, immune and DA changes. In conclusion, SIR induces mitochondrial and immune-inflammatory changes that underlie cortico-striatal DA perturbations and subsequent behavioural deficits, and responds to treatment with clozapine or NAC, with an additive effect following combination treatment. The data provides insight into the mechanisms that might underlie the utility of NAC as an adjunctive treatment in schizophrenia.

“Attenuation of rotenone toxicity in SY5Y cells by taurine and N-acetyl cysteine alone or in combination.”

Results: The combined taurine/NAC treatment also attenuated rotenone-induced reductions in aconitase activity suggesting the cytoprotection afforded by the combined treatment may be associated with anti-oxidative mechanisms. Together, our data suggest that a multi-targeted approach may yield new avenues of research exploring the utility of combining therapeutic agents with different mechanisms of actions at concentrations lower than previously tested and shown to be cytoprotective.

BACOPA MONNIERA EXTRACT

Created from the Brahmi plant which is native to the wetlands of India and has been a consistent part of traditional medicine for centuries. A 2013 study demonstrated that Bacopa Monniera extract has a potential to improve cognitive performance, particularly speed of attention by reducing choice reaction time.†

“Meta-analysis of randomized controlled trials on cognitive effects of Bacopa monnieri extract.”

Results: Nine studies met the inclusion criteria using 518 subjects. Overall quality of all included trials was low risk of bias and quality of reported information was high. Meta-analysis of 437 eligible subjects showed improved cognition by shortened Trail B test (-17.9 ms; 95% CI -24.6 to -11.2; p<0.001) and decreased choice reaction time (10.6 ms; 95% CI -12.1 to -9.2; p<0.001).

“An acute, double-blind, placebo-controlled cross-over study of 320 mg and 640 mg doses of Bacopa monnieri (CDRI 08) on multitasking stress reactivity and mood.”

Results: Outcome measures included cognitive outcomes from the MTF, with mood and salivary cortisol measured before and after each completion of the MTF. Change from baseline scores indicated positive cognitive effects, notably at both 1 h post and 2 h post BM consumption on the Letter Search and Stroop tasks, suggesting an earlier nootropic effect of BM than previously investigated. There were also some positive mood effects and reduction in cortisol levels, pointing to a physiological mechanism for stress reduction associated with BM consumption. It was concluded that acute BM supplementation produced some adaptogenic and nootropic effects that need to be replicated in a larger sample and in isolation from stressful cognitive tests in order to quantify the magnitude of these effects.

“CDRI-08 Attenuates REST/NRSF-Mediated Expression of NMDAR1 Gene in PBDE-209-Exposed Mice Brain.”

Results: The findings showed upregulated expression of NR1 and decreased binding of REST/NRSF to NR1 promoter after postnatal exposure of PBDE-209. Interestingly, supplementation with CDRI-08 significantly restored the expression of NR1 and binding of REST/NRSF to NR1 promoter near to the control value at the dose of 120 mg/kg. In conclusion, the results suggest that CDRI-08 possibly acts on glutamatergic system through expression and regulation of NR1 and may restore memory, impaired by PBDE-209 as reported in our previous study.

Results: In the biochemical tests, tissue malondialdehyde (MDA) levels were significantly higher in the traumatic brain-injury group compared to the sham group (p < 0.05). Administration of CoQ₁₀ after trauma was shown to be protective because it significantly lowered the increased MDA levels (p < 0.05). Comparing the superoxide dismutase (SOD) levels of the four groups, trauma + CoQ₁₀ group had SOD levels ranging between those of sham group and traumatic brain-injury group, and no statistically significant increase was detected. Histopathological results showed a statistically significant difference between the CoQ₁₀ and the other trauma-subjected groups with reference to vascular congestion, neuronal loss, nuclear pyknosis, nuclear hyperchromasia, cytoplasmic eosinophilia, and axonal edema (p < 0.05).

“Maternal vitamin D3 deprivation and the regulation of apoptosis and cell cycle during rat brain development.”

Results: Our results confirm that vitamin D(3) regulates these processes in the developing brain at both cellular and molecular levels. Compared to control animals, the embryos and pups from vitamin D(3) depleted mothers had significantly less apoptotic cells, this finding being most pronounced at birth. Additionally, there were significantly more mitotic cells but this was not associated with any particular developmental period. Targeted gene arrays specific for apoptosis and cell cycle genes confirmed a pattern of transcription deregulation in the deplete group consistent with the known properties of vitamin D(3). While most current vitamin D(3) research is focussed on the pro-apoptotic and pro differentiating properties of vitamin D(3) as adjuncts for the treatment of cancers, our findings highlight the important role that this hormone plays in normal development via these same properties specifically in the brain.

“Nicotinamide riboside, a trace nutrient in foods, is a vitamin B3 with effects on energy metabolism and neuroprotection.”

Results: Recent work investigating the effects of nicotinamide riboside in yeast and mammals established that it is metabolized by at least two types of metabolic pathways. The first of these is degradative and produces nicotinamide. The second pathway involves kinases called nicotinamide riboside kinases (Nrk1 and Nrk2, in humans). The likely involvement of the kinase pathway is implicated in the unique effects of nicotinamide riboside in raising tissue NAD concentrations in rodents and for potent effects in eliciting insulin sensitivity, mitochondrial biogenesis, and enhancement of sirtuin functions. Additional studies with nicotinamide riboside in models of Alzheimer's disease indicate bioavailability to brain and protective effects, likely by stimulation of brain NAD synthesis.
