Orthomolecular Interventions
Orthomolecular interventions include substances that have roles in promoting or addressing addiction, depending on individual metabolic requirements and the amount present in the body.
Vitamin B1 (thiamine)
Vitamin B1 and alcohol addiction
-
- Thiamin deficiency is a common effect of alcoholism (Dastur et al., 1976; Morgan, 1982).
- Thiamin deficiency can ( Zimatkin & Zimatkina, 1996):
-
- promote increased alcohol consumption
- result from excessive alcohol consumption
- Alcohol decreases thiamin availability in the body by (Jeynes & Gibson, 2017):
-
- decreasing its absorption by intestinal cells
- decreasing production of the enzyme that converts thiamin to the metabolically important coenzyme thiamin pyrophosphate (TPP)
Causes of thiamin deficiencies:
- inadequate intake and excessive consumption of refined grains and sugars
- poor nutrient absorption
- excessive alcohol consumption
Vitamin B3 (niacin)
There are two main forms of nicotinic acid known medically as Niacin and Nicotinamide.
Vitamin B3 deficiency is known as pellagra. Dr. Abram Hoffer reported that the earliest symptoms of subclinical pellagra appear as anxiety, depression, and fatigue (Prousky, 2015.)
Actions of vitamin B3 in regards to mental health:
- helps correct subclinical pellagra
- increases serotonin production by diverting more tryptophan conversion to serotonin (Gedye, 2001)
- has sedative, benzodiazepine effects (Hoffer, 1962)
- can increase the effectiveness of some sedatives, tranquilizers, and anticonvulsants (Hoffer, 1962, 24-31)
Vitamin B3 and alcohol addiction
- People with alcoholism have been shown to be deficient in vitamin B3 (Badawy, 2014).
- Niacin is depleted by (Petralli, “The HPA Axis: The ‘Home’ of Alcoholism.”):
- excessive metabolism of carbohydrates (alcoholics typically consume high-sugar, high-carbohydrate diets)
- chronic stress (promoted by alcohol consumption)
- Nicotinamide adenine dinucleotide (NAD) is a molecule required for energy production in all cells, is created from niacin.
-
- Low cell energy causes issues with physical and mental health
- Chronic heavy alcohol consumption reduces body capacity to synthesize NAD (Zelfand, 2021)
- In the context of low vitamin B3, the amino acid tryptophan is converted to vitamin B3 instead of serotonin. Low serotonin is associated with (Petralli, “The HPA Axis: The ‘Home’ of Alcoholism.”):
-
- carbohydrate and alcohol cravings
- compulsive/addictive behaviour
Causes of vitamin B3 deficiencies (Niacin, 2014):
- inadequate oral intake
- poor bioavailability from grain sources
- issues with absorption of tryptophan
- some metabolic disorders, and the long-term chemotherapy treatments
Vitamin B12 (cobalamin)
Vitamin B12 and mental health
A deficiency of vitamin B12 can affect mood, emotions, sleep, and can result in psychiatric disorders. (Valizadeh & Valizadeh, 2011)
Roles of vitamin B12 in the brain:
- Required for the synthesis of neurotransmitters including serotonin and dopamine
- Required for the preservation of protective myelin sheath around neurons
- Important for homocysteine metabolism
Psychiatric manifestations of vitamin B12 deficiency include (Oh & Brown, 2003: Dommisse, 1991):
- agitation, restlessness, irritability
- dementia
- depression, fatigue
- mild memory impairment
- negativism
- panic/phobic disorders
- personality changes
- psychosis
Vitamin B12 and addiction
- Supplementation with vitamin B12 during recovery may support healing of the brain and affected areas of the nervous system. (“These Are the 4 Best Vitamins for Opiate Withdrawal.”)
Vitamin B12 deficiency
40% of Americans have low levels of vitamin B12, and 20% of elderly people have severe vitamin B12 deficiencies. This is due to a decreased ability to absorb B12 with older age (Wolters et al., 2004) (Andrès et al., 2004) (Greenblatt & Brogan, 2016).
People with depression may have higher needs due to decreased vitamin B12 transport across the blood-brain barrier (Arora, Sequeira, Hernández, Alarcon, & Quadros, 2017), or because of increased breakdown of vitamin B12 in brain tissue (Gaby, 2011)
Vitamin B12 levels can be normal in blood tests but be deficient in the cerebral spinal fluid. (Prousky, 2015)
Vitamin B12 and vegetarians
When comparing omnivores and vegetarians, it was found that vegetarians had (Kapoor et al., 2017):
• significantly lower Serum B12 levels
• significantly higher Methylmalonic Acid (MMA) levels
The most common causes of vitamin B12 deficiency:
- vitamin B12-deficient diet
- vegetarianism or veganism
- decreased stomach acid production
- bacterial overgrowth in the small intestine
Vitamin C
Vitamin C is required for the synthesis of many compounds important for good mental health. Some of these are:
- tyrosine
- thyroxine
- norepinephrine
- epinephrine
- serotonin
- carnitine
- corticosteroids.
Vitamin C has been shown in research to (Meister, 1994):
- reduce psychological stress
- decrease blood pressure
- lower cortisol levels
Functions of vitamin C in the brain (Smythies, 1996):
- Prevents oxidation of dopamine into toxic derivatives (Baez, Segura-Aguilar, Widerslen, Johansson, & Mannervik, 1997)
- Protects NMDA receptors from glutamate toxicity
- Counteracts the effects of amphetamines
- Enhances the effects of older antipsychotic medications like haloperidol
Vitamin C and mental health
- 3 g/day of vitamin C supplementation in healthy volunteers significantly decreased monoamine oxidase activity (MAO). MAO is responsible for metabolizing serotonin, norepinephrine, and dopamine. (Gaby, 2011)
- Vitamin C exerts a powerful antioxidant and anti-inflammatory effect in the body. It plays a role in brain health by supporting the production of serotonin, and the regulation of dopamine and glutamate. (Zelfand, “Vitamin C, Pain and Opioid Use Disorder.”)
Vitamin C and addiction
Vitamin C deficiency and vulnerability to addiction
- Chronic stress significantly depletes vitamin C.
- Vitamin C plays an essential role in the body’s response to stress by helping to regulate cortisol.
- Deficiency of vitamin C may result in higher levels of cortisol and an impaired stress response, which may increase vulnerability to addiction (Zelfand, 2020).
Opioid addiction and vitamin C depletion:
- Chronic use of opioids can deplete vitamin C resulting in a greater level of oxidative stress damage in the body (Zelfand, 2020).
Vitamin C and opioid withdrawal
- Through its interruption of the brain chemistry associated with opioid addiction vitamin C has been found to help reduce withdrawal symptoms. (Zelfand, 2020).
- Vitamin C also plays a role in the recycling of glutathione, an important antioxidant in the body that is depleted by opioid addiction (Zelfand, 2020).
- By preserving concentrations of glutathione in red blood cells and liver cells, vitamin C can help to address glutathione depletion, Low levels of glutathione can contribute to the perseverance of addiction (Zelfand, 2020).
Vitamin C and smoking
- Smoking increases the body’s requirements for vitamin C while at the same time decreasing the body’s absorption of it (Healthfully, n.d.).
- Vitamin C deficiency in smokers is evidenced by lower levels in the bloodstream Schectman et al., 1989).
Causes of vitamin C deficiency
- restrictive diets
- diet lacking in sources of vitamin C, especially fresh fruit and vegetables
- digestive tract disorders, e.g. diarrhea, Crohn’s and colitis
- smoking
- alcoholism
- chronic inflammatory conditions
Signs of vitamin C deficiency
- bleeding or swollen gums
- frequent nosebleeds
- dry hair, split ends
- easy bruising
- slow wound healing
- fatigue
- moodiness
- depression and cognitive impairment (Plevin & Galletly, 2020)
Vitamin D
Vitamin D, which is made from cholesterol in the skin and UVB radiation, is a neurosteroid hormone that has roles in brain development and normal brain function.
Vitamin D and mental health
- Vitamin D regulates the transcription of genes involved in pathways for synaptic plasticity, neuronal development and protection against oxidative stress (Graham et al., 2015).
- Vitamin D-deficient cells produce higher levels of the inflammatory cytokines TNF-α and IL-6, while cells treated with vitamin D release significantly less.
- In the adrenal glands, vitamin D regulates tyrosine hydroxylase, which is the rate-limiting enzyme for the synthesis of dopamine, epinephrine, and norepinephrine.
- In the brain, vitamin D regulates the synthesis, release, and function of serotonin. Serotonin modulates executive function, sensory gating, social behaviour, and impulsivity (Patrick & Ames, 2015).
Vitamin D and addiction
- Roles of vitamin D in addiction include reduction of pro-inflammatory cytokines and oxidative stress, and neurotransmitter synthesis and regulation in the brain and gut.
Causes of vitamin D deficiency
- limited sun exposure
- strict vegan diet (most sources of vitamin D are animal-based)
- darker skin (the pigment melanin reduces the vitamin D production by the skin)
- digestive tract and kidney issues
- obesity (vitamin D is sequestered by fat cells)
Measuring vitamin D
The best indicator of vitamin D status is serum 25(OH)D, also known as 25-hydroxyvitamin D. 25(OH)D reflects the amount of vitamin D in the body that is produced by the skin and obtained from food and supplements.

Magnesium
Magnesium and mental health
Magnesium in the context of mental health (Kirkland, Sarlo, & Holton, 2018):
- calms neurotransmission by regulating glutamate and GABA
- modulates the HPA axis
- has roles in the synthesis of serotonin and dopamine
- regulates cortisol levels
- increases brain-derived neurotrophic factor (BDNF)
- is required for enzyme systems that use thiamine (vitamin B1) and pyridoxine (vitamin B6) – these vitamins are cofactors in the production of serotonin, GABA, and melatonin (Kanofsky, & Sandyk, 1991)
- decreases activation of the NMDA receptor which in turn, decreases excitatory neurotransmission (Bartlik, Bijlani, & Music, 2014)
Magnesium and alcohol addiction
Magnesium in the context of alcohol addiction (Kirkland, Sarlo, & Holton, 2018):
- calms neurotransmission by regulating glutamate and GABA
- modulates the hypothalamic–pituitary–adrenal (HPA) axis
- has roles in the synthesis of serotonin and dopamine
- regulates cortisol levels
- increases brain-derived neurotrophic factor (BDNF)
- deficiency promotes anxiety and decreases stress tolerance (Henrotte, 1986).
Magnesium deficiency and alcohol addiction
- Alcohol consumption depletes magnesium (McLean and Manchip, 1999)
- Magnesium deficiency in alcoholics is common, with a prevalence of between 13–50 percent. (Dingwall et al., 2015) (Wilkens Knudsen et al., 2014).
Magnesium and opioid withdrawal:
- Magnesium deficiency can contribute to the pain, and nervous system and muscular issues, experienced by individuals withdrawing from opioids (Nabipour et al., 2014).
- Magnesium exerts a calming effect, helping the body to relax both mentally and physically during withdrawal (Miller-Reiter et al., 1995).
Causes of magnesium deficiencies include:
- loss of soil magnesium due to farming practices
- following the standard American diet pattern, as it is high in processed and nutrient-deficient foods,
- decreased magnesium levels in foods, especially cereal grains (Guo, Nazim, Liang, & Yang, 2016)
- low dietary protein (needed for magnesium absorption)
- gastrointestinal disorders (e.g. Crohn’s disease, malabsorption syndromes, and prolonged diarrhea)
- stress, which causes magnesium to be lost through urine (Deans, 2011), and
- chronically elevated cortisol, which depletes magnesium (Cuciureanu, & Vink, 2011).
- high doses of supplemental zinc (competes for absorption)
- alcoholism
- certain diuretic medications
- lower dietary intake, absorption, and increased loss of magnesium (common in the elderly)
Zinc
Zinc and mental health
- Zinc regulates the storage and release of neurotransmitters (Zinc Regulates, 2017)
- Zinc has critical roles in axonal and synaptic transmission development and brain cell growth and metabolism (Pfeiffer & Braverman, 1982).
- Zinc is required for the production of the enzyme, superoxide dismutase, and therefore helps to provide antioxidant support in the body. (Preston, “Cigarette Smoking-Nutritional Implications.”)
- Zinc has anti-anxiety and antidepressant effects, and is critical for regulating excitatory glutamate and NMDA receptor activity in the brain. (Andrews, 1990; Joshi, Akhtar, Najmi, Khuroo, & Goswami, 2012).
Zinc and alcohol addiction
- Alcohol consumption frequently promotes zinc deficiency and altered zinc metabolism (Barve et al., 2017).
Causes of low zinc with alcohol consumption:
- decreased intake and increased urinary excretion (Jeynes & Gibson, 2017).
- negative effects on zinc transporters (Skalny et al., 2018)
Effects of low zinc in the context of alcoholism:
- Impediments to neurotransmission
- leaky gut with a corresponding increase in gut toxins in the blood and brain (Skalny et al., 2018)
- increased inflammatory signaling
- increased oxidative stress
Zinc and smoking addiction
- tobacco smoke is high in cadmium. Cadmium competes with zinc for body enzyme binding sites, altering enzyme function in a negative way. Increasing body levels of zinc can help mitigate the effects of cadmium.
Essential fatty acids
Essential fatty acids and mental health
- Polyunsaturated fatty acids (PUFAs) (omega 3 and 6 fatty acids) are necessary for normal development and function of the brain.
- Omega 3 fatty acids and their metabolites have roles in regulating inflammation, neuroinflammation, and neurotransmission (Larrieu, & Layé, 2018).
Essential fatty acids and addiction
EFAs and alcohol addiction
- Addictive behaviours are associated with neuroinflammation.
- Studies show that alcohol-induced neuronal inflammation and damage can be offset by essential fatty acids (Barve et al., 2017).
- Fish oil has been shown to alleviate withdrawal symptoms (Shi et al., 2019).
- Omega 3 fatty acid intake supports healthy brain function while recovering from chronic alcohol use (Smith, 2021).
Omega 3 fatty acids and opioid withdrawal
- Low omega 3 fatty acid status has been linked to decreased levels of dopamine. (“These Are the 4 Best Vitamins for Opiate Withdrawal.”)
- Supplementation with omega 3 fatty acids may help to reduce drug-seeking behaviours during opioid maintenance and withdrawal as a result of the protective role they may play in mitigating composition of the gut microbiome (Hakimian et al., 2019).
- Preclinical data suggests that a diet enriched with omega 3 fatty acids may also help to alleviate anxiety and associated behaviours that accompany withdrawal (Hakimian et al., 2019).
Omega 3 fatty acids and opiod relapse prevention
- Supplementation with omega 3 fatty acids may help to facilitate a positive shift in the composition of the gut microbiome.
- This may help to reduce anxiety, which is often a contributing factor in relapse (Hakimian et al., 2019).
Reasons for EFA deficiencies
- Inadequate dietary intake
- Poor absorption
- Deficiencies of nutrients required for EFA metabolism
- Issues with metabolism that cause decreased incorporation of, or increased removal of, fatty acids from cell membranes
GABA (gamma-aminobutyric acid)
GABA and mental health
- GABA is the most important calming neurotransmitter in the body.
- Low levels of GABA are associated with anxiety (Lydiard 2003: Braverman 2003)
- GABA levels are depleted by chronic substance abuse
Glutamine
Roles of glutamine in mental health:
- is a precursor molecule for the production of the neurotransmitters glutamate and GABA.
- provides fuel for the brain and stimulates many brain functions (Treatment Protocol for Alcoholism, n.d.)
- supports brain detoxification by supporting glutathione production (Yu et al., 1999)
- protects digestive tract cells from damage.
Glutamine and addiction
- Glutamine decreases physiological cravings in general (Addiction, n.d.), and especially for alcohol
- Glutamine is made in the body by the kidneys and liver and certain brain cells. Chronic alcohol consumption damages the liver and kidneys which reduces their production of glutamine. (Treatment Protocol for Alcoholism, n.d.)
- Glutamine can be converted into glucose in the brain without raising insulin levels. Elevated insulin promotes alcohol cravings.
NAC (n-acetylcysteine)
- N-acetylcysteine, more commonly known as NAC, is a derivative of the amino acid cysteine.
NAC in the context of mental health:
- has roles in inflammation regulation and antioxidant production, and is required for the production of glutathione
- modulates neurotransmitters including glutamate and dopamine, and provides neurotrophic support (Dean, Giorlando, & Berk, 2011)
- regulates inflammation
- supports mitochondrial energy production
- supports neurotransmitter metabolism
Phenylalanine
Phenylalanine is an essential amino acid. It can be found in 3 forms: L-phenylalanine , D-phenylalanine and DL-phenylalanine, a combination of both (Phenylketonuria, n.d.).
Phenylalanine and mental health
- People have reported mood improvement after taking phenylalanine. This may be because phenylalanine increases production of chemicals in the brain such as dopamine and norepinephrine (PHENYLALANINE: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews, n.d.)
- Phenylalanine also appears to protect endorphins from routine destruction. Supplementation of phenylalanine therefore increases endorphins levels and can improve depressed moods” (Greenblatt & Brogan, 2016) Page 139.
Causes of Phenylalanine deficiencies
- A low-protein diet
- phenylketonuria (PKU, genetic condition)
Theanine
Theanine and mental health
- Theanine is a calming amino acid. The L-theanine form of theanine is extracted from green tea.
- L-theanine helps reduce anxiety by enhancing alpha brain wave activity and increasing GABA synthesis. Increased GABA levels promote feelings of calm and well-being by raising brain serotonin and dopamine levels (Mason, 2001).
Tryptophan/5-HTP
Tryptophan and 5-HTP and mental health
- Serotonin, regarded as the happy, feel good neurotransmitter, is synthesized from the amino acid tryptophan. Tryptophan is converted in the body to 5-HTP , which is then converted into the neurotransmitter serotonin.
- Serotonin is depleted by substance abuse. Tryptophan and 5-HTP help maintain proper serotonin levels
Tyrosine
Tyrosine is a dietary amino acid that also functions as a neurotransmitter.
The body can also make tyrosine from the amino acid phenylalanine
Tyrosine and mental health
Tyrosine is a precursor molecule for the neurotransmitters dopamine, noepinephrine, and epinephrine, and is also required for the production of thyroid hormones.
Tyrosine and opioid WIthdrawal:
- Tyrosine may help to mitigate symptoms of depression, anxiety, and fatigue that accompany opioid withdrawal (Opiate Withdrawal Vitamins, 2018).
Causes of deficiencies
- a low-protein diet
