1The Methylation Cycle and Mental Health
by
Phyllis D. Light, MA

Depression, anxiety, and other mental illnesses are very challenging for the individual and their family. Natural mental health approaches can help bring the body, mind and spirit back to the present and closer to balance. Whether someone is already taking medication or are considering natural options, being equipped with current information can help make well informed decisions for improved mental health.


Methylation
Methylation is not one specific reaction that occurs in one location in the body, but many reactions taking place continually in our cells, especially in the liver. A methyl group consists of one carbon atom connected to three hydrogen ones which are passed around a group of molecules in a cycle. So any time this takes place, methylation occurs. This can be written as

CH3.


Methylation is important in gene expression and repair and the process can turn on a gene or activate an enzyme. When the methyl group is removed, the reaction stops, which turns off a gene or deactivates an enzyme. Methylation of DNA plays a role in kidney repair and in dysregulation of inflammatory diseases.
In its influence on mental health, the methylation cycle is critical to the metabolism of catecholamines in the synapse via an enzyme (COMT) as well as the synthesis of melatonin, carnitine, and CoQ10. Methylation is also required to inactivate histamine.
Methylation occurs in the liver when the body takes harmful substances, including phenols, and turns them into a less harmful substances during phase two detoxification. This allows for its safe excretion. Methylation also allows the body to detoxify toxins within the cells, repair damaged DNA, and create new cells.
Methionine, which already contains a methyl group, is an amino acid that occurs naturally in all protein foods, especially meats and dairy. Using magnesium, methionine becomes SAMe, which, using ATP (adenosine triphosphate) travels throughout the body delivering a methyl group to any number of reactions. After SAMe delivers the methyl group, it becomes homeocysteine. As an aside, ATP, produced by mitochondria within the cells, is stored energy which can be released as fuel for metabolic processes. Vitamins B6, B12, and folic acid are necessary to reduce homocysteine and keep the methylation process occurring.
Homeocysteine is then ready to accept another methyl group which transforms it back into methionine. However, if there are not enough methyl groups to transform the homeocysteine, then levels build in the body. Elevated homeocysteine levels are associated with heart disease, poor circulation, and other degenerative disorders.
Pathways of Conversion
There are several pathways for the conversion of homeocysteine to methionine. One pathway is folate plus B12. A different pathway is supplied by the choline-based TMG (trimethylglycine aka glycine betaine) and DMG (dimethylglycine) which act similar to B12. Either of these pathways can give a methyl group to homeocysteine for the conversion to methionine. Some people may make better use of one pathway than another.
TMG converts to SAMe (s-adenosyl methionine), which then converts the amino acid tyrosine to dopamine, noradrenalin and adrenalin. These brain chemicals are important for balanced mood and blood pressure, motivation, concentration, alertness and stress management. SAMe also converts tryptophan amino acid to serotonin and melatonin brain chemicals, which are important for balanced mood and sleep. SAMe helps support healthy joints, and muscle and liver function.
Another pathway for converting homeocysteine is with B6 and magnesium. This pathway converts homeocysteine to cysteine. Other conversions happen in this pathway including making glutathione and taurine. One step is adding molybdenum and continuing on to convert toxic sulfite molecules to really helpful sulfate molecules.
The methylation process is inhibited by oxidative stress when converting homocysteine to important antioxidants such as glutathione and the sulphur containing amino acids such as taurine and sulphate which are also key in supporting phase II detoxification in the liver.
Other supplements which support the methylation cycle are calcium, zinc, selenium, methionine and folic acid.
Factors Affecting Methylation
According to research by Carl Pfeiffer, MD, PhD, 45% of the population are under-methylators and 15% are over-methylators, (which together totals 60%) and 40% of people are neither.

The formation of methyl groups initiates serotonin, and thus melatonin, production. Therefore, if you are a under-methylator, you can increase your methylation and have more appropriate levels of serotonin and melatonin. The dissolution of methyl groups in an over-methylator can decrease methylation which can decrease aggression or hyperactivity.


The process of methylation is influenced by:
Genetic factors

Psychological/emotional/physical stress

Smoking, alcoholism and other environmental toxins

Diet and nutrition (including supplements), especially B-vitamin and methionine intake


Elevated levels of homocysteine suggests a blockage in methylation. Homocysteine has been investigated as a separate risk factor for coronary heart disease. It has been postulated as a putative factor in endothelial dysfunction and arteriosclerosis.
Undermethylation
According to research by Carl Pfeiffer, undermethylation or high histamine is the dominant chemical imbalance in about 20% of people with psychosis. However, only about 20% of those diagnosed with undermethylation will respond to nutritional therapies designed to remedy the imbalance. Most undermethylated persons in the general population tend to be high-achievers in good mental health. Laboratory indications include whole-blood histamine above 70 mg/ml and folate overload, creating a low methyl to folate ratio. This can result in lower levels of dopamine, norepinephrine, and serotonin. These types can benefit from supplemental methionine, SAMe, and inositol (methyl donor).
The following issues are associated with undermethylation: depression, compulsions (like OCD), addictions (gambling/shopping/sex/alcohol, etc.), eating disorders (anorexia/bulimia), and phobias. According to Pfeiffer, these folks react badly to folate, even dietary folate in fresh vegetables could worsen their depression. They responded well to methionine and calcium supplements.
The following is a list of characteristics and factors associated with undermethylation. The presence of 30-50% of the factors may be sufficient for diagnosis.
delusions (thought disorder)

self-motivated during school years

very high libido

higher metabolic rate

high fluidity (tears, saliva, etc.)

high accomplishment before onset of serious symptoms

adverse reaction to B-complex vitamins

sparse chest/leg/arm hair

suicidal tendencies

addictiveness

prior diagnosis of OCD or ODD
Overmethylation
Overmethylation or low histamine is the dominant chemical imbalance for about 45% of persons diagnosed with schizophrenia. This imbalance is associated with extreme deficiencies of folate and Vitamin B-12, and usually coincides with elevated serum copper. Laboratory indications include whole-blood levels below 40 mg/ml, and depressed absolute basophils.
These folks tend to suffer from paranoid schizophrenia, bipolar disorder, psychosis, anxiety/panic attacks, hallucinations, hyperactivity, and depression. Pfeiffer found that these people often benefitted from large doses of folic acid, B12, B3, B6, zinc, and manganese.
The following is a list of characteristics and factors associated with overmethylation. The presence of 30-50% of the factors may be sufficient for diagnosis.
auditory hallucinations

high anxiety or panic tendency

hyperactivity

low libido

religiosity

tendency to be overweight

nervous legs, pacing

dry eyes and mouth

belief that everyone thinks ill of them

low motivation during school years

high pain threshold

paranoia


depression

sleep disorder

history of eczema

absence of seasonal allergies

frenetic activity during illness onset

tinnitus


upper body/neck/head pain

hirsutism

food/chemical sensitivities

artistic or musical ability

copper overload

adverse reaction to estrogen therapy

adverse reaction to anti-histamines

adverse reaction to SAMe

improvement after lithium

self mutilation

obsessions without compulsions

post-partum onset of psychosis

adverse reaction to SSRI’s

adverse reaction to methionine

improvement after benzodiazepines

diagnosis of paranoid schizophrenia

low blood histamine

low absolute basophils



Pyroluria
Pyroluria could overlap with either under-or-over-methylation or exist on its own. It is associated with anxiety, depression, food sensitivities/celiac disease, social withdrawal, learning disabilities/ADHD, schizophrenia and autism. Very severe cases result in mental retardation and delayed growth and puberty. In some cases psychological symptoms could be alleviated within just a few days with supplemental B6 and zinc.
During the synthesis of hemoglobin in the body, kryptopyrroles are generated as waste products. Kryptopyrroles, however, don’t serve any useful biological purpose and are normally excreted. If someone with pyroluria is low in either zinc, B6 or both, they won’t secrete kryptopyrroles which then tend to build up in the blood, more so under stress. Heavy metal toxicity can also cause elevated kryptopyrroles.
Kryptopyrroles have a tendency to bind with zinc and vitamin B6, when then reduces their availability to the rest of the body. Zinc and B6, of course, are nutrients critical for the functioning of your entire body and mind–including your digestion, immune system, cognitive functioning and emotions. Over time, zinc and B6 deficiencies have serious effects on the function of the body. Often supplementation with manganese, vitamins C and E may be necessary.
Pyrolurics also have a greater than normal need for omega-6 fatty acids, particularly dietary arachidonic acid (AA), which is found in eggs, butter, red meat and liver) and the essential fatty acid GLA (gamma linolenic acid), found in black currant seed oil and evening primrose oil. Once determined, supplementation, along with stress management, can improve symptoms but should be continued over time. Omega 3s can worsen symptoms of pyrolurics since both omega 3 and 6 compete for certain receptors.
Additional considerations for the pyroluric include the need for improving digestion and hydrochloric acid status and the avoidance of phytate-containing foods such as grains, legumes and soy. If positive for pyroluria one must also avoid excess fish oil, copper, and red and yellow food dyes.
The characteristics and factors associated with pyroluria are:
severe inner tension

ongoing anxiety or anxiousness

episodes of irritability or anger

poor stress tolerance (with added stress of any kind making the symptoms worse)

digestive issues and difficulty digesting protein

frequent colds and infections

joint pain or stiffness

acne


eczema or psoriasis

mood swings and reactivity

poor short term memory

tendency towards being a loner

little or no dream recall

white spots on finger nails

poor morning appetite with tendency to skip breakfast

morning nausea

pale skin which burns easily in sun with poor tanning

sensitivity to bright light

hypersensitive to loud noises

reading difficulties (e.g. dyslexia)

poor ability to cope with stress

mood swings or temper outbursts

easily upset by criticism

histrionic (dramatic) tendency

augmentative/enjoy argument

new situations or changes in routine (i.e., traveling) particularly stressful

higher capability and alertness in the evening, compared to mornings

poor short term memory

abnormal body fat distribution

belong to an all-girl family with look-alike sisters

dry skin

reaching puberty later than normal

difficulty digesting, a dislike of protein or a history of vegetarianism

tendency toward being a loner and/or avoiding larger groups of people

stretch marks on skin

poor sense of smell or taste

feel very uncomfortable with strangers

frequently experience fatigue

tendency to overreact to tranquilizers, barbiturates, alcohol or other drugs (in other words, a little produces a powerful response)

tendency toward anemia

family history of mental illness or alcoholism in family

sweet smell (fruity odor) to breath or sweat when ill or stressed

prone to acne, eczema or psoriasis

tendency toward feeling anxious, fearful and carrying lifelong inner tension

difficulty recalling past events or people

bouts of depression or nervous exhaustion

prone to frequent colds or infections

ADD/ADHD

Avoid boredom and correct authority issues.

Work on balancing any chemical imbalances using Pfeiffer’s method.

Autism

Possible lack of mercury detox ability due to depletion of metallothionein, a protein needed by the body and brain to detox metals. It is synthesized in the liver and kidneys and is its production is dependent on the availability of the dietary minerals, as zinc, copper and selenium, and the amino acids histidine and cysteine.


Pfeiffer believed that autism is caused by an inability to cope with environmental oxidative stress, involving weak functioning of the neuroprotective metallothionein/glutathione system. The causes for this can include genetics, infection or trauma during pregnancy, and exposure to environmental toxins. This condition results in inability to regulate copper and zinc, hypersensitivity to metal toxins, extremely poor immune function & hypersensitivity to vaccines, yeast overgrowth, inability to break down casein & gluten, and worst of all..... incomplete maturation of brain cells and synaptic connections.... especially in hippocampus, amygdala, and pineal gland.

Under or over methylation and malabsorption also influence the incidence of autism.


Depression
The major causes of depression include nutritional imbalances, metabolic disorders, abuse, chronic stress, chronic pain, life circumstance such as the death of a loved one, moving, or personal problems, genetics, chronic or serious illness and substance abuse. Nutritional imbalances include zinc deficiency, copper overload, folate imbalances, and omega 3 and 6 imbalances. Other nutrients that may affect depression include methionine, folate, vitamins B 6 and 12, niacin, vitamins C, A dnd E, and the minerals selenium, chromium, manganese and iodine. Metabolic imbalances include methylation disorders, severe oxidative stress, toxic metal overload, adrenal deficiency and low thyroid.
