Magnesium Status and Dementia: Is There a Link ?

Magnesium and DementiaA new study published in Neurology, shows people with either low or high blood levels of Magnesium may have a higher risk of developing dementia.

Approximately 9,500 individuals participated in this prospective study.  Participants with an average age of 65 who did not have dementia were followed for an average of 8 years.  Serum Magnesium levels were measured at the start of the study.  Results were adjusted for variables like alcohol intake, body mass index, smoking status and kidney function, which may affect dementia risks and Magnesium levels.  Participants were divided into quintiles based on their serum Magnesium levels.

During this follow up period, over 800 individuals developed dementia.  Over 650 of these individuals were diagnosed with Alzheimer’s Disease. The incidence of dementia was found to be 30% higher in both the lowest blood Magnesium groups and the highest blood Magnesium groups.  Since this was an observational study only, no causality could be determined from the study outcomes.

There was however a few limitations on the way the study was set up.  First, Magnesium levels were only taken at the onset of the study, so changes in these blood levels may have occurred during the follow up period.  Second, blood levels of Magnesium may not be a reliable measure of total body Magnesium, meaning a person can have a normal serum Magnesium level and still have a Magnesium deficiency.  These limitations confirm that further research is needed.

The National Institute of Health (NIH) lists Magnesium as being involved in over 300 enzymatic processes in the body, such as helping to maintain normal nerve and muscle functions, keeping our bones strong as well as supporting a healthier immune response.  This important mineral is also necessary for supporting healthy blood pressure and blood sugar management.  70% – 80% of the population in the United States is not achieving the recommended intakes of daily Magnesium.

Lutein: For the Brain? Adults and Children May Benefit

Lutein and Brain for Adults and KidsLutein, a carotenoid, is usually associated with its benefits for ocular support.  This carotenoid is commonly found in both vegetables and fruits.  Research supports the role Lutein plays in the retina and its ability to decrease the risk of age related eye diseases.  Currently, Lutein is beginning to be recognized as support for the brain.

Lutein is taken up into brain tissue on a selective basis and is the main carotenoid in adult and infant brains.  Increased levels of Lutein correlate with improve cognitive function in older individuals.  Interestingly enough Lutein concentrations in the macula of the retina correspond with the levels of Lutein found in the brain tissue, and provides a non invasive means to measure Lutein in the brain.  This reinforces research showing increased macular pigment density in adults being significantly associated with improvements in cognitive performance.

Lutein also plays a role on cognition in early life.  Lutein is the preferred carotenoid taken up in cord blood and in breast milk.  Young brains show the ratio of Lutein to total carotenoids to be twice those found in adults which accounts for over half the concentration of total carotenoids.

The increased proportion of Lutein found in young brains suggests Lutein is needed during neural development.  Recent studies in children 8 – 10 years of age, shows macular pigment density was significantly related to academic performance and better memory.

Lutein’s role as an antioxidant and a natural anti-inflammatory may be why Lutein is so important.  In a randomized double blind placebo controlled study in healthy newborns supplementing Lutein significantly increased serum antioxidant activity providing a benefit when in brain tissue.

Ginkgo May Enhance Performance, Boost Brain Health for Active Men

Ginkgo Biloba Enhances Performance and CognitionAccording to a small study extracts of Ginkgo Biloba may offer both mind and body advantages for young active men.

18 young active men participated in this study.  Participants were randomly assigned to receive either a standardized extract of Ginkgo Biloba or a placebo.  The study lasted six weeks.  Improvements in VO2max (maximal oxygen uptake) and blood antioxidant capacity were seen in both groups, however the greatest increases were seen in the Ginkgo Biloba group. Participants in the Ginkgo Biloba supplementation group also showed increased brain-derived neurotrophic factor (BDNF) during exercise.  BDNF acts on certain neurons of the peripheral nervous system and the central nervous system.  These proteins help to support the survival of existing neurons and encourage growth of new neurons.  BDNF is vital to higher thinking, learning and memory.

Although no statistical significance was noted between the groups (a marginal increase of 6% vs 1% was seen in VO2max) researchers attribute that to the dosage levels used in the study, since previous studies have shown even more benefits with higher doses.  Researchers believe that the polyphenolic compounds found in Ginkgo Biloba enhance antioxidant effects by both indirectly boosting the actions of antioxidant enzymes like glutathione peroxidase, SOD, and catalase and by directly scavenging reactive oxygen species (ROS).  A 20% increase in SOD activity was seen in the Ginkgo Biloba group compared to the placebo group.

Larger studies are needed.

Lutein Levels Linked To A More Agile And “Youthful” Brain

Lutein and CognitionA new study finds a high intake of Lutein may slow down cognitive decline.

60 healthy adults between the ages of 25 and 45 participated in this study.  Carotenoid levels were assessed by measuring MPOD (Macular Pigment Optical Density), which is considered a trusted indicator of Lutein levels in the brain. Event related brain activity was used as a gauge of cognitive function and was recorded as the participants performed cognitive control testing.  Study results showed MPOD was related to both specific electrical brain activity and age during the decision making process, known as the P3 wave.  Younger adults showed a larger abundance of P3 than the older participants however, the older participants with higher MPOD levels displayed P3 measures equal to the younger participants.  Researchers concluded that Lutein appears to have a protective role in the brain since the study data indicated that participants with more Lutein were able to utilize more cognitive resources to finish their tasks.

Besides being beneficial to brain health, Lutein and Zeaxanthin have been shown to provide support for vision and vision diseases since Lutein appears to accumulate in both the brain and in the eyes.  The ability of Lutein in brain processing, memory, speed and processing is intriguing since Lutein cannot be manufactured on its own in the body.

Further study is warranted.

Micronutrient Supplementation For Mothers Boosts Infant Cognitive Health

Infant CognitionA major follow up study has determined pregnant women should take more micronutrients besides iron and folic acid to increase the long-term cognitive development of their children.

The Supplementation with Multiple Micronutrients Intervention Trial (SUMMIT) lasted from 2001 – 2004.  Over 31,000 pregnant women participated in this study.  The study goals were to determine if more micronutrients during pregnancy were necessary to increasing long-term cognitive and brain development.  Half the study participants received iron and folic acid supplements (IFA) during their pregnancy and for 3 months after their babies were born.  The other half of the study participants received iron and folic acid in addition to other micronutrients like B6, zinc and iodine (MMN).

Positive effects of the MMN supplement group were seen in 487 children who were assessed for cognitive ability at the ages 3 – 5 years old.  After 10 years of age, researchers tested almost 3,000 children who were now between 9 and 12 years of age.  The MMN Group totaled 1,466 children and the IFA group had 1,413 children.  The goals of this second round of testing were to assess the long term effect of MMN supplementation on socio-emotional, cognitive and motor development in the children and to assess the effect of socio-environmental and biomedical determinants on these results.

Children born from women in the MMN group showed significant proficiency in general intellectual ability and procedural memory when compared with the children of the women in the IFA group. This is equivalent to cognitive development gained from an additional half a year of schooling.   In general the children born to mothers in the MMN group showed improvements in socio-emotional, fine motor and cognitive abilities when compared with the children of the other group.

Omega-3’s Linked to Better Cognitive Function in Mildly Impaired Older People

Omega-3 and CognitionA new study finds daily supplementation with Omega-3 essential fatty acids may improve measures of cognitive function like perceptual speed and memory.

86 people with mild cognitive impairment (MCI) were randomly assigned to receive a placebo (olive oil) or an Omega-3 supplement (EPA 720 mg DHA 480 mg) daily for 6 months.  The average mean age of the participants was 71 years of age. Significant improvements in scores on Basic Cognitive Aptitude Tests (BCAT), which measure cognitive function, were seen in the group taking the Omega-3 essential fatty acid supplements.  Additionally significant improvements in working memory, space imagery efficiency and perceptual speed were seen in the Omega-3 group while no improvements were seen in recognition memory or mental arithmetic efficiency.  Men tended to see significant improvements in space imagery efficiency, working memory, and perceptual speed, while women saw significant improvements in space imagery and perceptual speed.  Both men and women saw significant improvements in BCAT scores compared to the placebo group.

Because the study group was small further research is needed.

Make sure your fish oil is molecularly distilled to remove potential toxins.  Also a Fish oil that is manufactured to comply with strict European standards will be free of heavy metals, PCB’s, dioxins, pesticides and other unwanted compounds.  An enteric coating will protect the Fish Oil  from the harsh environment of the stomach, and then  the softgel will better travel to the small intestine where it can be digested and its fatty acids released and absorbed into the body. This prevents a fishy aftertaste and odor, and is helpful to sensitive individuals.  Some products will use lemon oil to help with the digestion of the Fish Oil softgel without any fishy burps.

Resveratrol Shows Metabolic and Brain Signaling Benefits

ResveratrolA new animal study found that daily supplementation with Resveratrol may increase energy metabolism, cell signaling pathways and neurotransmission.

23 male adult monkeys were randomly assigned to one of three groups: A control group fed a healthy diet, A negative control group fed a diet high in sugar and fat and a group fed a diet high in sugar and fats and supplemental Resveratrol (80 mg per day for the first year and 480 mg per day for the second year).  The study lasted 2 years.  Researchers used proteomics to identify changes in the expression of 12 specific proteins in the brains of these rhesus monkeys.

Improvements in energy metabolism and the efficiency of cell signaling pathways and neurotransmission in the group supplementing with the Resveratrol in addition to the high fat and sugar diet were seen.

This study adds to the existing science on the healthy benefits of Resveratrol, a very powerful polyphenal.  A lot of research has focused on Resveratrol’s cardiovascular benefits due to the nutraceuticals association with the “French Paradox”.  This phrase was used to describe the low incidence of obesity and heart disease in the French people even though they have a diet moderately high in fat.  It is believed to be their consumption of Red wine that neutralizes the damage of their high fat diet.

Further studies are needed.

A good Resveratrol product will be standardized to 200 mg of trans-resveratrol (the phyto-nutrient in the resveratrol that gives the polyphenal its beneficial properties).  Additional Grape Seed Extract may be added to provide additional antioxidant benefits.
