New study demonstrates efficacy of vitamin D supplementation with autism spectrum disorder

Approximately 2% of American children experience symptoms among the autism spectrum including deficits in social interaction, impairment in verbal and nonverbal communication, and stereotyped patterns of activities. Many families seek integrative doctors to investigate food sensitivities, environmental toxins, nutritional deficiencies, and metabolic imbalances not seen on the usual laboratory testing.

According to a study published 2 weeks ago in The Journal of Child Psychology and Psychiatry, researchers demonstrated the efficacy of vitamin D supplementation in autism spectrum disorder (ASD). Vitamin D has an essential role in neurodevelopment, gene regulation, immune function, inflammation, and overall health. Previous studies have shown a link between the risk of ASD and vitamin D insufficiency. In addition, vitamin D deficiency during pregnancy is linked with adverse effects in the fetus and an increased risk of autism.

This study was a 4-month, double-blinded, randomized, placebo-controlled trial including 109 children with ASD from outpatient clinics and five private autism treatment centers. Serum vitamin D levels were measured at the beginning and at the end of the study.

Vitamin D supplementation was dosed at 300 IU per kg/day and not to exceed 5,000 IU/day. The autistic symptoms of the children improved significantly following 4-months vitamin D supplementation, which was not seen in the placebo group. There was a significant improvement in irritability, hyperactivity, social withdrawal, stereotypic behavior, and inappropriate speech as well as significantly fewer autistic mannerisms such as, repetitive hand movements, creation of noises, and jumping.

This is the first double-blinded RCT demonstrating the efficacy of vitamin D supplementation in children with ASD. Nutrition is incredibly important and can be difficult to accomplish for children with Autism Spectrum Disorders. It can be difficult for some parents to get their kids to eat a nutrient dense diet. Children are growing, the brain is developing and there tends to be some nutritional gaps due to lack of variety in their diet, soil deficiencies, or eating processed, convenience foods. Children may be influenced by advertising or packaging and sometimes pick products to eat. A well balanced diet consisting of whole foods should be the number one priority and foundation of their health but supplements can definitely fill in some of the gaps to support optimal health.

The level of nutrient intake that maintains the best possible health is highly variable from person to person. Lifestyle choices and environmental exposures filtered through genetic predisposition are fundamental factors in ASD, and a successful treatment approach must include investigation into these factors. It is important to assess the nutrient status of the child. This can be the antioxidant status, vitamins, essential fatty acids, vitamin D, B12, folate, calcium, etc. An organic acid test is also a great test to assess nutrient deficiencies, oxidative stress, and detoxification impairment as well as stool testing to assess the gut microbiome.

New study demonstrates lutein and zeaxanthin increases brain function

According to a recent study from the University of Georgia published in the Journal of the International Neuropsychological Society, researchers demonstrated the effect of lutein and zeaxanthin on neurocognitive functioning. The research team used fMRI technology to examine how levels of these compounds affect brain activity.

Previous research has demonstrated the benefits of lutein and zeaxanthin on eye health and more research is emerging on their benefits on cognition in older adults.

In this study researchers used a functional MRI to monitor the brain activity of over 40 adults between 65 and 86 years old and found that individuals with higher levels of lutein and zeaxanthin did not require as much brain activity to complete the task.

The level of lutein and zeaxanthin were assessed through serum and noninvasive flicker photometry. There is a natural deterioration process of the brain as people age, but the brain compensate to some degree by increasing brain activity to maintain the same level of cognitive performance.

As a result, individuals with lower levels of lutein and zeaxanthin used more brain power and relied on different parts of the brain in order to remember the word pairings they were taught. On the other hand, those with higher levels minimized brain activity to complete the task.

I also shared a study a month ago in the journal Redox Biology, in which researchers demonstrated that n-acetyl-cysteine (NAC) may prevent the metabolic declines associated with aging.

Patients and healthcare providers are always seeking prevention strategies and ways to minimize age related memory decline in older adults. Dietary modification and nutritional supplements are the best strategies to help to support this.

Lutein, zeaxanthin, NAC, vitamin D, and fish oils can be used to provide protective measures against the natural aging process in older adults. An organic acid test is a great test to identify nutrient deficiencies, oxidative stress, and detoxification impairment. In addition, assessing methylation cofactors such as folate and B12 are also important as these are common deficiencies in the elderly.

Study recommends statin use for the primary prevention of cardiovascular disease

According to a new study published 3 days ago in JAMA, the U.S. Preventive Services Task Force (USPSTF) recommended the use of statins for primary prevention of cardiovascular disease.

They recommend the use of low- to moderate-dose statins in adults ages 40 to 75 years without a history of cardiovascular disease (CVD) who have 1 or more CVD risk factors (dyslipidemia, diabetes, hypertension, or smoking) and a calculated 10-year CVD event risk of 10% or greater.1

The USPSTF concluded that the harm of low- to moderate-dose statin use in adults aged 40 to 75 years is minimal.

In contrast, recent previous studies demonstrate how the education on statins are deceptive and create the appearance that are safe and effective in prevention of cardiovascular disease. There is no questions that statins are effective at reducing cholesterol levels, but they have failed to substantially improve cardiovascular outcomes or have succeeded in reducing the risk of mortality. 2 The role of high cholesterol as an etiological factor in cardiovascular disease (CVD) has been a source of controversy and debate for decades. Studies have demonstrated that older adults with low levels of cholesterol are just as atherosclerotic as those with high levels.3

Also, another study demonstrated how statins stimulate atherosclerosis and heart failure. This study suggests that statins may be causative in coronary artery calcification and can act as mitochondrial toxins that impair muscle function in the heart and blood vessels through the depletion of coenzyme Q10 and ATP generation.4

Statins inhibit the synthesis of vitamin K2 which protects the arteries from calcification. In addition, statins inhibit the biosynthesis of selenium containing proteins. This impairment may be a factor in congestive heart failure as a selenium deficiency is seen with cardiomyopathies.

Health care providers have many more tools today than simply to look at the standard lipid panel to assess cardiovascular health. It is essential to perform a thorough assessment for all of these patients looking at lipid fractionation profiles, chronic inflammatory markers (ferritin, hs-CRP, fibrinogen), nutrient markers (magnesium, potassium, selenium, copper, folate, B12, B6, zinc, and calcium), fat soluble vitamins (CoQ10, vitamin D, vitamin K, Vitamin A, Vitmain E), oxidative stress factors (homocysteine, insulin, and lipid peroxidases), heavy metals, and a fatty acid profile.

At the end of the day protocol driven treatment like this fail. Each person’s biochemical individuality exerts a major influence on his or her health. The level of nutrient intake that maintains the best possible health is highly variable from person to person. Lifestyle choices and environmental exposures filtered through genetic predisposition are fundamental factors in the expression of disease and a successful treatment approach must include investigation into these factors.

Approximately 1 in 5 children with Celiac disease do not heal on a gluten free diet

Celiac disease is an autoimmune disease triggered by the consumption of gluten-containing foods. The medical approach for celiac disease is a lifelong gluten-free diet. However, recent evidence demonstrates that a gluten-free diet may not be enough to prevent many complications associated with this disease.

According to a new study published last week in the Journal of Pediatric Gastroenterology and Nutrition, approximately 20% of children with celiac disease have intestinal abnormalities after one year following a strict gluten free diet.

In this study, researchers reviewed medical records of 103 children and adolescents with celiac disease. The main treatment for celiac disease is a gluten-free diet, which was followed for an average of 2.4 years. In addition, the children also had endoscopy and biopsy at least two times at diagnosis and after one year on a gluten-free diet.

The study focused on the rate of persistent celiac enteropathy which was present in 19% of the children. These results suggest that 1 out of 5 children with celiac disease may have persistent enteropathy, despite following their recommended gluten-free diet which can lead to long-term effects and complications.

Few studies have looked at the effect of non-gluten proteins and celiac disease. An all-too-common contributor to non-responsive celiac disease is cross-reactivity with other foods. Assessing gluten-associated cross-reactive foods is essential for patients with gluten sensitivity and celiac disease since these patients are sensitized to a broad range of dietary proteins due to enzyme dysfunction, villi damage and other disorders.

As a result, many functional abnormalities can persist such as increased gut permeability, pancreatic insufficiency, small-intestinal bowel overgrowth, nutritional deficiencies, hypochlorhydria, and allergies.

Patients with celiac disease many times have to do more than just follow a gluten-free diet to maintain optimal health. Although a majority of celiac patients feel better after implementing a gluten-free diet, they continue to have poor nutrient status. Celiac disease attacks and damages the villi of the small intestine, resulting in the body not being able to absorb all the nutrients it needs. The most common deficiencies are vitamin D, calcium, folate, vitamin B12 and iron. It is importance to assess the nutrient status. This can be antioxidant status, vitamins, essential fatty acids, vitamin D, etc. In addition, it is essential to use stool testing that can assess the overall function of the gastrointestinal tract to rule out autoimmune triggers, digestion and absorption markers, as well as inflammatory and immune markers.

New study demonstrates omega-3 fatty acids promote clearance of beta-amyloid peptides

New research published in The FASEB Journal provides more evidence that fish oil supplementation and an additional benefit for Alzheimer’s disease by improving the function of the glymphatic system. This system is responsible for clearing waste from the brain and metabolites such as amyloid-β peptides. 

In this study researchers found fish oil supplementation significantly promotes the clearance function of the lymphatic system and Aβ clearance from the brain. In addition, omega-3 fatty acids help maintain the brain homeostasis which essential for neurological diseases, traumatic brain injury, and sleep disturbances.

There was another study published in July 2015 in The FASEB Journal where researchers saw a clearance of amyloid-beta protein and reduced inflammation in the neurological tissues with fish oil supplementation.

Omega-3 fatty acids are also essential nutrients involved in numerous metabolic processes that play a significant role in cognitive health. There was an interesting study published in January in the Journal of Alzheimer’s Disease in which researchers found a link between Omega-3 levels, homocysteine, and brain atrophy rates. Homocysteine plays a role in regulating phospholipid metabolism and omega-3 distribution by the methionine cycle. As a result, B vitamins are essential for the synthesis of phospholipids. This study demonstrated when omega-3 levels are in an upper normal range, B vitamins slow cognitive decline and brain atrophy.

In addition to omega-3 fatty acids there are also several nutrients to consider. A study published last September in the journal, Neurology, demonstrated that resveratrol stabilized amyloid-beta40 (Abeta40) in patients with mild to moderate Alzheimer’s disease. This biomarker declines when the disease progresses.

Another study published last year in JAMA Neurology demonstrated a significant association between vitamin D insufficiency and cognitive decline specifically seen Alzheimer’s disease and dementia.
In addition, studies have also demonstrated low levels of magnesium in the brains of patients suffering from Alzheimer’s disease. Magnesium L-threonate is a unique patented form of magnesium that has the ability to cross the blood brain barrier and increase learning ability, working memory, as well as short- and long-term memory.

Glutathione is also essential for neurodegenerative disease which I highlighted last week and its importance in the aging. This powerful antioxidant has been found to be depleted in the brain of neurodegenerative disorders. The extent of glutathione depletion appears to mirror the severity of the disease and is the earliest known indicator of degeneration. The brain has difficulty handling significant amounts of oxidative stress due to the presence of polyunsaturated fatty acids and low levels of antioxidants such as glutathione. In conclusion, providing antioxidant support with NAC or glutathione can also provide a beneficial effect in all neurodegenerative disorders.

Increasing glutathione levels may provide protective measures against age related decline

Glutathione is a powerful antioxidant that helps support detoxification pathways by providing protective measures against environmental stresses, air pollutants, heavy metals, and pharmaceuticals. Numerous condition has been associated with a decline of detoxification pathways such as cardiovascular disease, diabetes, cancer, and neurodegenerative conditions.

According to a new study published in the journal Redox Biology, researchers at Oregon State University demonstrated that n-acetyl-cysteine (NAC) may help maintain glutathione levels and prevent the metabolic declines associated with aging. This powerful antioxidant declines with age and helps the body resist the stresses of everyday life.

In this animal study, researchers demonstrated that cells from younger animals are more resistant to stress than those from older animals. In younger animal cells stress doesn’t cause a rapid loss of glutathione as seen in older animals. As a result, prophylactic use of NAC increased glutathione levels in the older cells and offset cell death.

I also shared a study earlier this year published in June in PLOS ONE in which researchers from Thomas Jefferson University demonstrated a potential benefit of n-acetylcysteine (NAC) in patients with Parkinson’s disease. The study showed that patients receiving NAC improved both mental and physical abilities with brain imaging studies that tracked the levels of dopamine.

This demonstrates that NAC may have a unique physiological effect on the brain that alters the disease process and improves the function of dopamine neurons and offers a new approach for managing patients with Parkinson’s disease.

Glutathione is an important antioxidant which has been found to be depleted with the natural aging process and also seen in patients with neurodegenerative conditions. The extent of glutathione depletion appears to mirror the severity of disease and is the earliest known indicator of degeneration.

N-acetyl-cysteine can definitely play a significant a role in preventing the increased toxicity faced with aging and the body’s reduced ability to eliminate toxins. NAC has the ability to improve the metabolic resilience that lost with the aging process as well as it detoxification support. Increasing NAC can reduce the toxicity of some prescription drugs, cancer chemotherapies, and support other health issues. Therefore, using NAC as prophylactic support instead of a treatment can allow glutathione levels to be maintained to provide protective measures against the natural aging process in older adults.

Folate improves verbal communication in autistic children according to study

Approximately 2% of American children experience symptoms among the autism spectrum. Many of these children have difficulty interacting and communicating with others. The only currently approved medications for autism are antipsychotic medications that address some symptoms but many times lead to unwanted side effects. Most of these families seek integrative doctors to investigate food sensitivities, environmental toxins, nutritional deficiencies, and metabolic imbalances not seen on the usual laboratory testing.

According to a study published in Nature’s Molecular Psychiatry, researchers demonstrated that therapeutic doses of folinic acid can help improve the language and communication skills of children with autism spectrum disorder (ASD).

Previous research has identified a link between autism and abnormalities in the metabolism of folate as well as genes involved in folate metabolism. In addition, other studies have demonstrated that children of mothers who took folate supplements before during pregnancy had a lower risk of having a child with ASD. Researchers have also described cerebral folate deficiency (CFD) in which the concentration of folate is below normal in the central nervous system but not in the blood. Many children with CFD have ASD symptoms and respond well to high-dose folinic acid. The research team also demonstrated that folate receptor autoantibodies were commonly found in children with ASD.

In this study, researchers found that children with folate receptor autoantibodies had a more favorable response to treatment with folate. Improvement in verbal communication was significantly greater in children who received folinic acid compared with those receiving the placebo.

Folate is not the only important nutrient for this children. I shared a study earlier this year in January published in PLOS One which found that vitamin B12 levels in the brain are significantly lower in children with autism. In this study autistic children were found to have brain vitamin B12 levels three times lower then what is commonly seen in adults in their fifties. These differences were not seen in serum B12 levels. This large deficit of brain B12 in individuals with autism may provide insight to why these patients experience neurological and neuropsychiatric symptoms.

Autism spectrum disorders are also associated with oxidative stress, which may play an underlying role in the decreased brain B12 levels observed in this study. These results suggest there may be a need for supplemental vitamin B12 and antioxidant support to prevent or decrease oxidative stress. This may include using n-acetyl-l-cysteine, glutathione, and/or s-acetyl-glutathione.

Assessing other methylation cofactors such as folate are also important as a folate deficiency has been associated with developmental delay, autism, and is essential in treating these conditions as identified in the study above. An organic acid test is also a great test to assess nutrient deficiencies, oxidative stress, and detoxification impairment as well as stool testing to assess the gut microbiome.

Low vitamin D levels during pregnancy may be linked to an increased risk of ADHD

According to a study published in The Australia & New Zealand Journal of Psychiatry, pregnant women who took vitamin D during pregnancy had children with fewer symptoms of ADHD. Researchers demonstrated for every 10 nmol/L increase in umbilical blood vitamin D levels, there was an 11% reduced risk of ADHD symptoms.

In this study 1,233 children from were monitored. Researchers measured vitamin D levels in umbilical blood and mothers completed the Child Behavior Checklist (CBCL) when their child was 2½ years of age. The CBCL questionnaire can be used to identify early symptoms of ADHD, but an ADHD diagnosis cannot be made at that age.

The research team demonstrated that there was a clear association in mothers who had taken vitamin D and had umbilical blood levels greater than 25 nmol/L had children with lower ADHD scores. This was after they had corrected for other factors, such as the mother’s age, smoking, alcohol, obesity, education, number of children, psychiatric disease in the parents, child’s sex, age and seasonal variation.

There has not been a previous link between vitamin D and ADHD or that this could be identified at such an early age. However, we cannot conclude or prevent which children will develop ADHD later in life. In addition, this study confirm that vitamin D will protect against ADHD but previous studies have demonstrated the role of vitamin D in the early brain development.

There was interesting study in February 2015 published in FASEB Journal which described that serotonin may be a possible link demonstrating how vitamin D and fish oil support cognitive function. Many brain based conditions, such as ADHD commonly has low brain serotonin. This study explains how serotonin is a critical modulator of executive function, impulse control, sensory gating, and pro-social behavior.

Researchers link serotonin production and function to vitamin D and omega-3 fatty acids, which suggests one way that these important nutrients help the brain function and affect our behavior.

The bottom line is it we need optimize every patient’s nutrients status based upon testing and support accordingly and we cannot forgot supporting these individuals with essential fatty acids. These are major deficiencies in the US and assessing and supporting optimal vitamin D and essential fatty acids levels would optimize brain serotonin concentrations and function. As a result, we can possibly prevent and alleviate some of the symptoms associated with these disorders without the harmful side effects.

Magnesium supplementation improves insulin sensitivity and glucose control

According to a new study published last month in Pharmocological Research, researchers demonstrate magnesium supplementation significantly improves HOMA-IR index and fasting glucose.
Over the past several decades diabetes has become a growing epidemic and it’s a fact that more than 50% of Americans are magnesium deficient. I cannot emphasis enough the importance of magnesium deficiency as a serious and common health problem. Magnesium plays a key role in more than 350 enzymes in the body. It is involved in virtually every metabolic process occurring in the body. Magnesium is the second most abundant intracellular cation and a cofactor involved in the modulation of glucose transport. In addition, a magnesium deficiency interferes with the tyrosine-kinase activity of the insulin receptor as well as increases intracellular calcium concentration which is associated with impaired insulin sensitivity, so it makes sense that a magnesium deficiency could play a significant role in the development of insulin resistance, metabolic syndrome, and type 2 diabetes.

This review consisted of 1,362 individuals from 21 RCTs including 684 and 678 individuals into the magnesium and control groups from studies published between 1992 and 2015. The range of magnesium supplementation was from 1 to 6 months and the doses ranged from 300 mg to 600 mg of magnesium per day. The impact of magnesium supplementation on plasma concentrations of glucose, HbA1c and insulin, and HOMA-IR were assessed.

The results of the meta-analysis demonstrated that magnesium supplementation for greater than 3 months significantly improves the HOMA-IR index as well as fasting glucose in both diabetic and non-diabetic individuals.

How much magnesium is enough? Unfortunately, we do not have a great way to measure magnesium status. For example, serum magnesium represents only 1% of magnesium stores. Magnesium is homeostatically controlled in the serum and measuring serum magnesium levels provides many false negatives. By the time your serum is low, you are very deficient as the body cannot maintain the serum magnesium levels. Serum magnesium is not the answer. Red blood cell magnesium is definitely better and can be done by most labs and all functional medicine labs. I test RBC magnesium levels on all my patients and it’s surprising to see how many patients that are deficient.

Chemical exposure has been linked to low levels of vitamin D

This study investigated data from 4,667 adults between 2005 and 2010. EDC exposure was measured by a urine analysis. The researchers found that individuals who were exposed to larger amounts of phthalates had lower levels of vitamin D in the bloodstream than the those who were exposed to smaller amounts of the EDCs. This link was strongest seen in women. It is possible that EDCs alter vitamin D through some of the same mechanisms that they use to impact other hormones in the body.

We live in an ever-increasing toxic environment. We are exposed to According to a new study published Tuesday in the Journal of Clinical Endocrinology & Metabolism, researchers discovered a link between chemical exposure and reduced serum vitamin D levels.

Endocrine disrupting chemicals (EDCs) have been known to cause adverse health effects such as diabetes and obesity by interfering with hormones in the body. There is currently more evidence than ever before. It is a fact that EDCs disrupt hormones in a manner that harms human health. Hundreds of studies have confirmed over and over again
EDCs are found in everyday products and throughout the environment. There are more than 85,000 manufactured chemicals. Many of these chemicals mimic, block or interfere with the body’s natural hormones and as a result, EDCs alter the way cells proliferate and develop.

Examples of EDCs:
• Bisphenol A (BPA)- found in food can linings and cash register receipts.
• Phthalates – found in plastics (PVC products, vinyl shower curtains) and cosmetics (perfumes, nail polish, lotion)
• Flame retardants, solvents, lubricants (PCBs, PBBs, and PBDEs)
• Pesticides (sprayed on conventional fruits and vegetables), insecticides.
• Heavy Metals: cadmium, lead, arsenic, mercury

Everyone is exposed to endocrine-disrupting chemicals, so the connection of these chemicals impacting vitamin D levels have a significant impact on our health. Vitamin D plays a significant role in musculoskeletal, immune and cardiovascular health as well as diabetes and cancer.

pesticides, herbicides, chemical solvents, xenobiotics, and industrial chemicals of all kinds that we get exposed through the food we eat, the water we drink and the air we breathe. These toxins accumulate in our body and contribute to the total toxic load that can cause a variety of health problems.
We need to do their best to minimize further exposure. We also have to keep in mind that our indoor environment is often more toxic than our outdoor environment.

Tip to Help Avoid EDCs:
• Eat organic produce (join your local CSA)
• Buy free-range, organic meats to reduce exposure from added hormones and pesticides.
• Buy products available in glass containers rather than plastic or cans when possible.
• Cookware: Replace non-stick pans with glass, ceramic, or cast iron.
• Drink filtered water
• Use a shower head with a filter
• Use household products that are fragrance-free and free of phthalates and BPA.

There is also significant evidence on the importance of diet and nutritional supplementation in maintaining detoxification pathways.

Nutritional Support for Detoxification
• Milk Thistle is one of the most protective herbs for the liver with hundreds of studies that confirm its protective properties.

• N-Acetyl Cysteine- supports phase II detoxification and precursor to glutathione

• Calcium D-Glucarate- aids in liver detoxification through the glucuronidation pathway. Xenobiotics, environmental toxins, and excess estrogens are cleared through this pathway.

• EGCg- the most extensively studied green tea polyphenol. Green tea also supports detoxification by enhancing the glucuronidation pathway in addition to modulating blood glucose, and its antioxidant and cancer protective properties.

• A Detoxification Program

Exposure to endocrine-disrupting chemicals are virtually impossible to avoid. We need to do our best to limit our exposure and make lifestyle and nutritional choices to properly detoxifying these chemicals.
