Although high-dose methyl donor supplements can help patients with methylation deficits, some healthcare professionals may occasionally encounter patients with an intolerance to methylation donors. Patients with an intolerance to methyl donors can experience worsening symptoms as well as the appearance of neurological symptoms, regardless of their need for methylation support. Neurological symptoms may include, anxiety, depression, irritability, and brain fog, among other symptoms.

Intolerances to methyl donor supplements are not properly understood and further research studies are required to help determine the frequency and effects of these problems. It’s believed that the impaired metabolism of catecholamines through COMT and MAOA may play a role in the intolerance of methylation donors. Increased SAH is also believed to cause a variety of adverse effects.

Case 1.0: Methyl Donor Intolerance with COMT Polymorphism

A 31-year-old female diagnosed with a long-term panic disorder and a recent onset of agoraphobia demonstrated homozygous for COMT and MTHFR single nucleotide polymorphisms, or SNPs, through genetic testing. Vanilmandelic acid, or VMA, and homovanillate, or HVA, urinary organic acids were found to be between low and low-normal, respectively, indicating poor clearance of norepinephrine and epinephrine. These catecholamines are catabolized through COMT methylation, and their poor clearance may increase anxiety symptoms. Her homocysteine levels, on the other hand, were normal which demonstrated that either the MTHFR SNP was still functional enough to maintain SAMe levels, or that increased oxidative stress was confounding the normal homocysteine finding by increasing transsulfuration of homocysteine for glutathione formation.

High-dose methylated folate and betaine supplements were recommended, however, the patient immediately reported experiencing aggravated symptoms. This may have occurred due to the increased production of SAMe from the combined effects of the supplementation. SAMe levels in the brain regulate the rate of epinephrine biosynthesis from norepinephrine through methylation, therefore, increased SAMe availability could have triggered increased epinephrine synthesis. The decreased clearance due to the COMT SNP could have been the underlying cause for the increased symptomatology. Replacing methylated folate with unmethylated folic acid, and the discontinuation of betaine supplements resulted in significant symptom improvement, including the resolution of agoraphobia.

Folic Acid Supplement Risks

Furthermore, fortification and standard folic acid supplementation are believed to increase the risks of developing neural tube defects, particularly at levels above 400 mcg/d of dietary folate equivalent units, or DFEs. Folic acid is a purely synthetic compound which must first be converted to tetrahydrofolate, or THF, by being cycled twice through the enzyme dihydrofolate reductase, or DHFR, to be utilized in methylation. One cause of folic acid side-effects include elevated unmetabolized folic acid or UMFA.

Folic acid side-effects and restricted capacity of liver DHFR are believed to be the main problems in folic acid metabolism. One-time folic acid doses of 260 mcg or multiple folic acid doses of 100 mcg throughout the day have been demonstrated to cause detectable UMFA. People who regularly consume fortified foods, such as ready-to-eat cereals and fortified grains, are exposed to folic acid beyond the Tolerable Upper Limit of 1.0 mg/d, and with the utilization of multivitamin supplements, it may increase beyond that.

Folic acid from supplements is also much more easily absorbed than folate from foods. One DFE is equivalent to 1 mcg of dietary folate as compared to 0.6 mcg of folic acid from supplements taken with food or fortified foods. Therefore, 400 mcg of folic acid is equivalent to 667 mcg DFE. Research studies associate higher levels of folic acid intake with other side-effects. Dihydrofolate, or DHF, the intermediate metabolite in the conversion of folic acid to tetrahydrofolate and UMFA, can cause a variety of health issues.

DHF has been demonstrated to prevent thymidylate synthase and purine synthesis enzymes, which can affect DNA synthesis. DHF is also believed to restrict the production of the MTHFR enzyme, which can lead to a decrease in methionine synthesis and homocysteine clearance. A recent research study demonstrated that 5 mg/d of folic acid supplementation in infertile men demonstrated an unexpected reduction in sperm DNA methylation, similar to patients homozygous for the MTHFR C667T polymorphism.

Other research studies have also reported a connection between fortification and standard folic acid supplementation and colorectal cancer. According to the research studies, UMFA may actually metabolize through photo-catalysis into DNA-toxic products. A recent research study which evaluated the connection between UMFA and colorectal cancer diagnosis demonstrated a small positive association in men and individuals with the MTHFR C677T genotype, both heterozygous and homozygous.

However, the research studies demonstrated a small inverse association with women. Higher UMFA was also found to be associated with anemia in US seniors who consumed alcohol and reduced NK cell cytotoxicity in otherwise healthy postmenopausal women. Recent research studies looking at folate receptors in epithelial cancers demonstrated a high frequency of receptor FR-alpha which uptakes UMFA. It is believed that FR-alpha promotes tumor progression and reduces apoptosis through increased expression of anti-apoptotic protein Bcl-2. Folic acid exposure to tumor cells in-vitro was demonstrated to enhance the progress of this process.

Methylation is a biochemical process required for cell division, DNA and RNA synthesis, gene expression, histamine clearance, detoxification, and cellular energy metabolism, among other essential functions. As important as methylation, however, many people are diagnosed with methylation deficits, which can cause a variety of health issues. Healthcare professionals recommend high-dose methyl donors to help treat methylation deficits. But, are we supplementing too much? Some patients may have an intolerance to methylation donors and they may experience side-effects, such as worsening symptoms or neurological symptoms.

Additional Topic Discussion: Acute Back Pain

Back pain is one of the most prevalent causes of disability and missed days at work worldwide. Back pain attributes to the second most common reason for doctor office visits, outnumbered only by upper-respiratory infections. Approximately 80 percent of the population will experience back pain at least once throughout their life. Your spine is a complex structure made up of bones, joints, ligaments, and muscles, among other soft tissues. Injuries and/or aggravated conditions, such as herniated discs, can eventually lead to symptoms of back pain. Sports injuries or automobile accident injuries are often the most frequent cause of back pain, however, sometimes the simplest of movements can have painful results. Fortunately, alternative treatment options, such as chiropractic care, can help ease back pain through the use of spinal adjustments and manual manipulations, ultimately improving pain relief.
