Function of Ingredients in Proprietary Blend
DMAE: DMAE (dimethylaminoethanol) is naturally present in small amounts in the human brain, and is found naturally in some foods, like anchovies and sardines. It is a precursor (building block) to Acetylcholine, a major brain neurotransmitter, which of course readily crosses the blood-brain barrier. Research indicates that supplementary DMAE promotes neurological processes which result in increased intellectual capacity, increased learning capability, increased short and long-term memory capability, promotes concentration, focus and alertness, and improves general sensory capabilities (vision, hearing, etc.) DMAE also contributes to the reduction of anxiety and hyperactivity, and contributes to stable behavior and mood. DMAE is part of the "choline cycle", which allows cells to convert certain specific biochemicals into each other as needed. One of the key roles for choline is as the rate-limiting factor in the production of acetylcholine. Acetylcholine is one of the dozen or so major neurotransmitters which allow brain and nerve cells to communicate with each other. Acetylcholine-using neurons are especially important in: (1) cognitive (intellectual) function; (2) memory formation and emotional modulation; and (3) the reticular-activating system (RAS). The RAS is a group of nerve clusters which sits at the top of the spinal cord and acts as a "traffic controller". The RAS determines what stimuli from the senses will be allowed to reach conscious attention, as well as what thoughts and feelings will be allowed to initiate corresponding bodily movements. It is partly due to the RAS that a passing angry thought or feeling doesn't automatically and instantaneously trigger violent behavior toward the object of our anger. It is the intensity of signals (mediated by DMAE- derived acetylcholine) from the RAS to the hippocampus and cerebral cortex which determines the intensity and duration of sustained mental focus and attention - the very issue at the root of genuine attention deficit disorder. Thus DMAE, by being the most effective precursor for brain/RAS acetylcholine, literally increases attention span, mental focus, and ability to screen out distracting and extraneous stimuli (both from the environment as well as from within). An acetylcholine-deficient RAS will have a difficult time maintaining a high level of focus, attention, alertness and arousal. DMAE is the most effective acetylcholine precursor for several reasons. Choline salts (e.g. choline bitartrate, choline chloride, choline citrate) are frequently broken down by bacteria living in our gut. DMAE does not suffer this fate. What choline is absorbed into the bloodstream has a poor ability to cross the blood-brain barrier. The blood-brain barrier is a two-part barrier which prevents toxins from entering the brain and also prevents disruptions of brain function due to surges in the blood of various nutrients, even those essential for optimum brain function. Unlike choline, DMAE passes easily through the blood-brain barrier. Because of this fact, DMAE has been shown to be effective at doses as low as 10-20 mg, although doses of 500-1000 mg are often needed. The unique effectiveness of DMAE is also due in part to its ability to inhibit choline oxidase, an enzyme which can divert choline away from acetylcholine production, into betaine production instead. And while a third acetylcholine precursor, phosphatidylcholine, is more effective than simple choline salts, studies have found large (and expensive) doses - 10 to 60 grams(!) - are often needed to elevate brain acetylcholine levels. Many other products on the market rely on phosphatidylcholine, which is not as effective as DMAE.

PREGNENOLONE: PREGNENOLONE is a precursor for all other steroid hormones naturally present in the body. It is converted directly into DHEA, which in turn converts to testosterone, estrogens, cortisol and aldosterone. It is this same set of successive conversions that makes human life possible. Without the presence of Pregnenolone, there can be no human steroid production. Research into Pregnenolone with factory workers and pilots began in the 1940's, and the evidence rapidly materialized that Pregnenoline had energizing and cumulative anti-stress, anti-fatigue and anti-depression effects, especially after it was taken after a period of two weeks. Studies at St. Louis School of Medicine showed the memory enhancement effects of pregnenolone, with improvement in spatial memory, perception and verbal recall. There is considerable evidence that pregnenolone modulates both NMDA and GABA receptors systems in the brain (which are involved in learning, memory and alertness and decrease with age). Pregnenoline enhances NMDA receptor function and lowers excessive GABA activity and seems to be a natural anti-depressant. During research conducted in the 1940's, it was found pregnenolone use resulted in a reduction in joint pain - it was used as a treatment for arthritis, but it was replaced by Cortisone in the 1950's. The body produces a steroid called cortisol, the levels of which increase with age, causing a number of problems. Pregnenolone counteracts the negative effects of accumulating cortisol levels in the body, including the enhancement of memory areas in the brain damaged by cortisol. One of the major determinants of the body's ability to detoxify poisonous chemicals is the health and effectiveness of the Cytochrome P450 enzyme system in the liver. Pregnenolone increases the overall P450 detox enzyme power of the liver by promoting conservation of the existing enzymes, promoting body detoxification processes. Works with TMG, detailed below.

TRIMETHYLGLYCINE (TMG): TRIMETHYLGLYCINE is what is called a methylation agent, composed of three methyl groups attached to one molecule of the amino acid glycine. It produces unique biological effects including lowering general homocysteine levels in the blood. Homecysteine is thought to contribute toward strokes and cardiovascular disease. TMG also contributes one of its methyl groups to DNA, potentially reducing DNA aging and errant DNA replication processes. In order for TMG to be effective in the body, it needs to have the synergistic co-factor of Vitamin B12, which is also included in the Brain Lightning™ formulation. Trimethylglycine also produces other compounds in the body, such as SAMe (S- Adenosylmethionine. SAMe is an active lipotrope form of Methionine, and is a cofactor in a number of critical biochemical reactions and is found in almost every tissue of the body. SAMe has been used in clinical studies to treat depression, schizophrenia, demyelination diseases, liver disease, dementia, arthritis, peripheral neuropthy and other conditions. Several studies have confirmed that SAMe is up to15% more effective in the treatment of depression than traditional pharmaceutical anti-depressants. SAMe improves and normalizes liver function. SAMe is used in Europe in the treatment of cirrhosis and damage caused by alcohol. SAMe is essential for the production of glutathione, a powerful antioxidant that protects the body from the damaging effects of free radicals. SAMe reduces the number of trigger points, reduces fatigue, reduces morning stiffness,and improves mood in fibromyalgia patients. SAMe improves the binding of neurotransmitters to their receptors sites in the brain. SAMe is essential for the regeneration of neuron axons following injury. SAMe is also essential for the formation of myelin sheaths that surround axons. In tests SAMe has shown great promise in the treatment of Peripheral Neuropathy, and HIV related peripheral Neuropathy. Alzheimer's and Parkinson's patients have very low levels of SAMe. SAMe is currently under investigation as a treatment for Parkinson's disease.

L-TYROSINE: Tyrosine is intimately involved with the important brain neuro- transmitters epinephrine, norepinephrine and dopamine. It is synthesized in the body from existing levels of phenylalanine. Environmental stress is associated with reduced levels of norepinephrine. Tyrosine prevents reduction of norepinephrine levels that are associated with stress. Many clinical studies, along with a large body of anecdotal evidence, indicate that tyrosine may prove to be a vital substance in alleviating depression, as well as the irritating symptoms of premenstral syndrome. Tyrosine is now reportedly being used as an aid in the treatment of and withdrawal from cocaine addiction. In one study, tryptophan and tyrosine were used in conjunction with the anti-depressant imipramine to treat chronic cocaine abuse with a reported 75-80 percent success rate. Researchers at UCLA and elsewhere, have also reported favorably on regimens containing tryptophan and tyrosine for the treatment of cocaine abuse. The importance of Tyrosine is based on the fact that it is a direct precursor to Thyroxine (Triiodo tyrosine) as well as being a precursor to Adrenaline and Noradrenaline. Thyroxine is, of course, a primary Thyroid hormone. Thyroxine deficiency results in a series of conditions including excess weight gain, cold hands and feet, decreased basal metabolism, etc.The catecholamine Adrenaline and Nor Adrenaline are critical in the following conditions: In Science magazine it was reported that Tyrosine lowers blood pressure by increasing Norepinephrine metabolites which through feedback shut down sympathetic output. In this same issue it was found that Tyrosine increased blood pressure 38% to 49% in hypotensive rats through accelerated peripheral synthesis of catecholamine. A study by Dr. I. Goldberg in Lancet revealed that catecholamine also controls immune system output. Allergy sufferers have responded well to Tyrosine. In the American Journal of Psychiatry, Dr. Alan J. Gelenberg postulated that a lack of available tyrosine results in a deficiency of nor adrenaline at a specific brain location, which in turn relates to mood problems such as depression.

HUPERZINE A: An amazing, safe alkaloid derived from the Chinese Club Moss, Huperzia serrata, Huperzine occurs in two forms: Huperzine A and Huperzine B, which has far less effect than Huperzine A. Double blind studies in China have demonstrated the positive effects of Huperzine A for the treatment of Alzheimer's Syndrome. It is currently approved for AD treatment in China. Huperzine A appears to relieve symptoms of Alzheimer's disease by blocking the depletion of acetylcholine in the brain. Huperzine A is currently under study by the US Army at Walter Reed Hospital as an antidote for nerve gas poisoning because of its protective effect on the cells of the brain. Huperzine A actually promotes the growth of nerve dendrites! Animal and cell culture studies, along with molecular structure data, suggest that Huperzine A is a potent acetylcholinesterase (AChE) inhibitor and may also protect neurons against glutamate-induced excitotoxicity. The molecule's strong specificity for AChE suggests it may lower liver toxicity and other adverse effects. Huperzine A costs approximately $500,000 per Kilo, because they have to gather it molecule by molecule. Brain Lightning™ uses only natural Huperzine A, as opposed to some formulations on the market which use synthetic Huperzine A. For more data, see this link. In orthodox medicine, there are two phamaceuticals used in the treatment of Alzheimers, tacrine and physostigmine, both of which unfortunately bind to receptors in the central nervous system, causing adverse effects. Also, the two orthodox drugs work on the AChE everywhere in the body instead of just in the brain, so their effect is severely limited. Huperzine A specifically targets the AChE in the brain, does much better in improving memory, does not bind to CNS receptors, and lasts more than ten times longer. Huperzine A is not known to have any toxicity at all, even at doses 100 times the therapeutic dose. Tens of thousands of people, if not more (considering China) have used Huperzine A with no evidence of toxicity anywhere in the body. See studies below

VINPOCETINE: Vinpocetine is more technically referred to as "ethyl apovincaminate." Derived from the periwinkle plant, Vinpocetine, a derivative of Vincamine, increases cerebral blood flow, increases the rate at which brain cells produce Adenosine TriPhosphate (ATP), creating more cellular energy, and increases the use of oxygen and glucose, feeding the brain cells. It also has the unusual effect of raising the level of serotonin in the brain, increasing the general brain information processing rate. It is commonly cited as an aid to improving memory. Literature suggests Vinpocetine may act to improve conditions related to insufficient blood flow to the brain including vertigo and Meniere's syndrome, difficulty in sleeping, mood changes and depression. Vinpocetine may also alleviate speech impairment, improve short-term memory, hearing, assist in the condition of multiple infarct dementia, increase resistance of neurons to lack of oxygen. Several brain boosters (ginkgo biloba, vitamin E, phosphatidylserine, to name just a few) are known to help restore failing memory, but Vinpocetine dramatically enhances memory even in healthy individuals. It also acts as a potent neuroprotective supplement. Strong clinical evidence exists that, in addition to its brain boosting properties, Vinpocetine's ability to improve blood flow also helps protect brain and heart function, prevents macular degeneration (a leading cause of blindness in the elderly), and improves hearing and inner ear problems, and even lessens depression and fatigue. See studies below

DL-PHENYLALANINE: Most amino acids, with the exception of glycine, can appear in two forms called the D- and L- forms. Each form is a reversed mirror image of the other. Amino acids in the L- form are the natural form of amino acids found in living plant and animal tissues, and are considered to be more compatible to human biochemistry than the D- forms. All amino acids used in human protein structures are of the L- form, with the exception of phenylalanine, which can also appear as DL-phenylalanine. Phenylalanine comes in two forms which are mirror images of each other: L-phenylalanine which has a nutritional value, and D-phenylalanine which has painkilling and depression alleviating properties which are attributed to its ability to block the breakdown of enkephalins, the brains natural pain killers. A third form, DL-phenylalanine, is a 50/50 mixture of these two forms. Phenylalanine activity is enhanced by additional Vitamin B6, especially in studies on depression. Vitamin B6 is, of course, included in Brain Lightning™. Phenylalanine deficiency can cause bloodshot eyes, cataracts and behavioral changes. It is one of the amino acids which the body cannot manufacture itself, but must acquire from food. It is abundant in meats and cheese. Phenylalanine is a precursor of tyrosine, and together they lead to the formation of thyroxine or thyroid hormone, and of epinephrine and norepinephrine which is converted into a neurotransmitter used by the brain to manufacture norepinephrine which promotes mental alertness, memory, elevates mood, and suppresses the appetite very effectively.


GABA: GABA (gamma aminobutyric acid), is an important amino acid which functions as the most prevalent inhibitory neurotransmitter in the central nervous system. GABA's high concentration in the hypothalamus suggests this amino acid plays a significant role in hypothalamic-pituitary function. The hypothalamus is a region of the posterior section of the brain and is the regulating center for visceral (instinctive) functions such as sleep cycles, body temperature, and the activity of the pituitary gland. Supplemental GABA can be useful in producing a state of relaxation. GABA works in partnership with a derivative of Vitamin B-6 (Pyridoxine - included in Brain Lightning™), to cross from the axons to the dendrites through the synaptic cleft, in response to an electrical signal in the neuron and inhibits message transmission. This helps control the nerve cells from firing too fast, which would overload the system. The action of GABA decreases epileptic seizures and muscle spasms by inhibiting electrical signals in this manner. Studies have shown that the site of action in the brain of benzodiazepams, including Valium, is directly coupled to the brain receptor for GABA. GABA itself can be taken instead of a tranquilizer to calm the body without the fear of addiction. Taken with the B-vitamins niacinamide and inositol, it prevents anxiety messages from reaching the motor centers of the brain by filling its receptor site.

GINGKO BILOBA: The primary causes of mental deficiencies is poor blood flow to the brain or "cerebral vascular insufficiencies." An answer to this problem may come from a plant which has been used for medicinal purposes since 2800 B.C. It is found in the oldest Chinese books on herbal medicine, known as materia medicas. The plant may provide the most important medicinal plant extract available as we enter a new millennium-nearly 5000 years later. The plant is Ginko biloba. Ginkgo works in a number of important ways to assist the brain. The effect of the plant on cerebral vascular insufficiency has been widely studied. An analysis of forty of the scientific articles reporting on this subject noted ginkgo's clear value in treating the "symptoms of aging" in the elderly. The studies looked at an extract of ginkgo which was standardized for the level of Ginkgo flavonglycosides. The active principles of Ginkgo extract are believed to have a regulating effect on the entire vascular system of veins, arteries and capillaries. Ginkgo extract may inhibit "Platelet activating factor" (PAF) and promote the metabolism of cerebral and neurosensorial cells. The most common usage of Gingko Biloba is for its widely accepted effects in the regulation of blood flow to the brain, legs and other extremities. It is also thought Gingko Biloba may act to counteract a number of conditions such as vascular insufficiency or tinnitus. Gingko Biloba has also been indicated in the treatment of intermittent claudication (pain while walking). Ginkgo not only assists the brain by increasing its supply of blood and oxygen, but also this plant has been shown to increase ability of brain cells to make use of glucose. Energy production is improved. Nerve signal transmissions are improved. Brain wave tracings are improved. Diverse population grouping have been shown to benefit from administration of ginkgo. The memory of college students as well as the elderly have shown improvement. Ginkgo facilitates short-term memory by increasing the speed of nerve impulses. In recent years, this plant has reached a highly valued status in Europe. In France, 1.5 percent of all prescription sales are for ginkgo leaf extract. The figure is 1 percent in Germany. In both of these countries, the extracts of the ginkgo leaf are among the leading prescription medicines. Worldwide, some 10 million prescriptions for the extract this plant leaf were written in 1989; roughly 100,000 physicians prescribe ginkgo as a regular part of their practices.

Research background on Huperzine A :
Research conducted at the Weizmann Institute of Science in Israel
"A moss extract that has been used for centuries in Chinese herbal medicine ­ to treat a range of symptoms from confusion and strain to swelling and schizophrenia ­ could hold the key to a new generation of drugs for treating Alzheimer's disease (AD), according to researchers at the Weizmann Institute of Science in Israel.
Mia Raves and her colleagues have determined the 3-D structure of a complex formed between Huperzine A (HupA) ­ a novel alkaloid extracted from the club moss Huperzia serrata ­ and the message-carrying brain enzyme acetycholinesterase (AChE), which is thought to be involved in AD. They found that the structure revealed a 'strikingly good fit between HupA and the enzyme' and concluded that it may be a possible starting point for designing 'a new generation of Alzheimer drugs with improved properties'.
According to one theory, memory impairments and other cognitive defects associated with AD patients result from the degeneration of nerve cells which release the message-carrying acetycholine. The deficiency of acetycholine in the brain that ensues is then compounded by the action of AChE, which breaks down acetycholine in the body.
The scientists used high quality crystals of AChE derived from electric organ tissue of the Torpedo fish (one of the richest sources of this enzyme) and soaked the crystals with HupA (Nature Struct. Biol., January 1997, p 57). Using X-ray crystallography they obtained a 3-D computer image of AChE-HupA binding. This revealed how the HupA blocks the enzyme by sliding 'smoothly into the active site of AChE where acetylcholine is broken down, and latches onto the site via a large number of subtle chemical links'. The binding closes off the enzyme's cutting machinery, thus protecting the acetylcholine.
Because the binding is very specific, says Professor Israel Silman, a protein chemist at Weizmann, HupA 'could be a potent drug even when used in small quantities', thus minimising the risk of side-effects. Professor Joel Sussman, a crystallographer and one of the authors of the study, commented: 'It is as if this natural substance were ingeniously designed to fit into the exact spot in AChE where it will do the most good'.
Several cholinesterase inhibitor (ChEI) drugs are already on the market, including tacrine (Cognex), physostigmine (Phy), E2020 (Aricept) and galanthamine, but these have significant limitations. For example, tacrine has been associated with liver toxicity at high doses and Phy has a short duration of action and low dosing range. The researchers at the Weizmann Institute believe that HupA 'may serve both to alleviate reduced AChE levels in the brain and to decrease neuronal cell death' and they have reported positive results from clinical trials in China.
According to Professor Tang Xi-Can, of the Shanghai Institute of Materia Medica, 'HupA has attracted considerable interest because of its unique anti-AChE activity as well as memory-enhancing effects on a broad range of behavioural models. HupA has good penetration through the blood-brain barrier, high oral bioavailability and longer duration of inhibitory action on AChE'. He described HupA as a 'novel Lycopodium alkaloid which is chemically unique from other agents for AD (Asia Pharmacol. Sini., November 1996, p 481).
By solving the structure of the 3-D complex, the researchers have determined how AChE is blocked and hope to use this information to design and analyse analogues of HupA with improved pharmacological characteristics."

Other Research and Evaluation
Alzheimer's disease is characterized by abnormalities and degeneration of neurons which depend upon acetylcholine and acetylcholine esterase for normal activity and viability. These cells located in the basal forebrain are also implicated in other neurological diseases such as Parkinson's disease. Huperzine A is a potent inhibitor of acetylcholine esterase, superior in activity to TACRINE, the first drug licensed in the USA for Alzheimer's disease and E2020 which was licensed recently by Eisai Pharmaceuticals. In addition, Huperzine A has been shown to protect neuronal cells in culture from death caused by the excitoamino acid glutamate. Because of the dual pharmacological action of Huperzine A, provides a unique and important activity for the treatment of AD and senile memory deficits.
Toxicology and efficacy studies of Huperzine A show it to be non-toxic even when administered at 50-100 times the human therapeutic dose. The extract is active for 6 hours at a dose of 2 µg/kg with no remarkable side effects.
In Alzheimer's disease, double blind controlled studies of over 160 patients, showed significant improvement measured by Weschler scale results, at doses of only 150 µg given twice daily (3-5 µg/kg).
Two important characteristics of Huperzine A distinguish it from TACRINE and E2020 as well as other experimental compounds in development. Huperzine A is highly specific for brain acetylcholine esterase (AChE) vs. AChE found elsewhere in the body. This selectivity is believed to be responsible for the relatively low toxicity of the extract. In addition, unlike the two approved drugs for Alzheimer's disease, TACRINE and E2020, Huperzine A has been shown to lack binding to receptors in the CNS that can cause side effects such as the muscarinic receptors M1 and M2.
The duration of action of Huperzine A at 3 hours is superior to TACRINE (2 hours) and physostigmine (30 minutes). In behavioral experiments of learning and memory enhancement in animals, the difference between amounts of the extract effective for memory and learning and the no-toxic-effect dose (from toxicity studies) was 30-100 fold. These data strongly suggest that Huperzine A can be useful in treating Alzheimer's disease with minimal side effects.

Pregnenolone
The role of pregnenolone and its enhancement of memory function are being explored with very interesting and promising results. The Geriatric Research Education and Clinical Center in St. Louis, Missouri is one of the world's leading research centers on pregnenolone. A 1995 study conducted at the Center suggested that low levels of steroid hormones might be the cause of learning and memory impairment (Flood et al., 1995). They also did a study in 1992, which found a relationship between pregnenolone levels in aging and the increase of cancer, and behavioral disorders in people whom receive drugs that block the synthesis of cholesterol (the precursor of pregnenolone) (Flood et al., 1992). The National Institute of Mental Health in Bethesda, Maryland also supports that pregnenolone is important for effective memory. The NIH study found that pregnenolone positively modulates NMDA receptors in the brain, which are believed to be responsible for retention (Mathis et al., 1994). A French research study in 1995 found that when they administered a series of cognitive tests to mice, those with the highest steroid hormone levels performed significantly better (Rebel et al., 1995). In addition to memory, serum levels of pregnenolone are also a factor in depression. The NIH found that people with clinical depression have significantly lower levels of pregnenolone. Pregnenolone levels were decreased in subjects with affective illness, particularly during episodes of active depression (Mathis et al., 1994).
