How Alcohol Causes Nutrient Deficiencies: A Functional Medicine Guide

Understanding How Alcohol Depletes Essential Nutrients: Insights from Functional Medicine

You meet a friend for a drink or two, relax with a beer or cocktail after a long day, enjoy a nice meal with your partner and share a bottle of wine, or attend a celebration where we have a few too many. By the time our week is over, we have had 6 or more drinks without even taking note.

This is common for many of us, but is it healthy?

Not at all: Alcohol is 100% toxic.

While moderate alcohol intake (2 drinks per week) may pose no significant harm to some individuals, excessive or chronic alcohol consumption (more than 2 drinks per week) can have detrimental effects on both physical and mental health, from gastrointestinal issues to the depletion of essential nutrients vital for health. Alcohol consumption is associated with higher risks of cancer (1), neurological and cognitive impairment, brain damage, fatty liver disease, and cirrhosis. (2,3)

As a matter of fact a British study examined brain scans of over 35k middle-aged and older adults, even just one to two alcoholic drinks per day is associated with negative changes in brain structure, including reductions in overall brain volume. (4)

In this blog, we'll explore the impact of alcohol on nutrient deficiencies from a functional medicine perspective, shedding light on how these deficiencies can compromise various bodily functions and contribute to health issues.

Understanding the Effects of Alcohol on Nutrient Depletion

Alcohol consumption interferes with the body's ability to absorb and utilize essential vitamins and minerals, leading to deficiencies that can have far-reaching consequences. Some of the key nutrients affected by alcohol include (5):

Magnesium Deficiency

Alcohol consumption can deplete magnesium levels in the body. (6) Magnesium is an essential “master” mineral involved in over 300 reactions, including energy metabolism, protein synthesis, muscle and nerve function, blood glucose regulation, and blood pressure control. It acts as a cofactor for enzymes involved in these processes, making it essential for overall health and well-being.

Signs and symptoms of magnesium deficiency can include:

Muscle cramps and spasms
Fatigue and weakness
Irregular heartbeat (arrhythmia)
High blood pressure
Insulin resistance and impaired glucose tolerance
Nausea and vomiting
Anxiety and irritability
Poor sleep
Headaches and migraines
Numbness and tingling in extremities

Selenium Deficiency

Selenium deficiency, often observed in alcohol drinkers, can manifest as myopathy and cardiomyopathy. Selenium plays a crucial role in muscle, immune, thyroid, and heart health, and its deficiency can impair these vital functions, causing serious health complications. (7)

Vitamin B1/Thiamine Deficiency

Thiamine plays a critical role in energy metabolism, supporting the growth, development, and function of cells. Thiamine deficiency is a well-known consequence of heavy alcohol consumption and can result in Wernicke-Korsakoff syndrome, characterized by neurologic symptoms such as confusion, memory impairment, and vision changes. Depletion of thiamine can result in fatigue, weakness, and impaired cognitive function. (8)

Vitamin B2/Riboflavin Deficiency

Riboflavin deficiency is associated with glossitis, cheilitis, and lingual papillae atrophy, which can lead to discomfort and difficulty in eating and speaking. Riboflavin plays a crucial role in maintaining oral and skin health, and its deficiency can manifest in these characteristic signs. (9)

Vitamin A/Retinol Deficiency

Alcohol can impair the absorption and utilization of vitamin A, resulting in abnormal dark adaptation and rough skin. Vitamin A is essential for vision, immune function, thyroid and skin health, so its deficiency can have wide-ranging effects throughout the body. (10)

Vitamin C Deficiency

Vitamin C deficiency, though commonly associated with scurvy, can also present with purpura and petechiae due to impaired collagen synthesis and vascular integrity. Vitamin C is a potent antioxidant and is critical for immune function and tissue repair, so its deficiency can compromise overall health. (11)

Vitamin D Deficiency

Alcohol can disrupt vitamin D metabolism, leading to altered bone metabolism and immune function. Vitamin D is crucial for calcium absorption, bone health, and immune regulation, so its deficiency can increase the risk of osteoporosis and infections. (12)

Vitamin E Deficiency

Alcohol-induced vitamin E deficiency can exacerbate oxidative stress, leading to cellular damage and inflammation. Vitamin E is a powerful antioxidant that protects cells from free radical damage, so its deficiency can contribute to various chronic diseases. (13)

Niacin Deficiency

Niacin deficiency, often observed in heavy drinkers, can present with skin photosensitivity, confusion, and pellagra. Niacin is essential for energy production and DNA repair, so its deficiency can affect multiple bodily functions, including cognition, energy, and skin health. (14)

Folate/B9, B6, B12, and S-Adenosylmethionine Deficiency

Alcohol use can deplete B6, B12, folate and S-adenosylmethionine levels, leading to anemia, altered methylation, and epigenetic effects. B6, B12, folate and S-adenosylmethionine are crucial for DNA synthesis, gene regulation, and methylation, so their deficiency can have far-reaching consequences for cellular function and health. (15, 16)

Methylation is essential for immune function, DNA protection, and the prevention of conditions like cancer and cardiovascular disease. A healthy methylation cycle produces glutathione, the body's most potent antioxidant and detoxifying agent.

The Link Between Alcohol, Nutrient Deficiencies, and Health Issues

The depletion of essential nutrients due to alcohol consumption can contribute to a range of health issues, including (17):

Neurological Disorders: Deficiencies in B vitamins, particularly B6, B12, and folate, can lead to neurological disorders such as peripheral neuropathy, cognitive impairment, and even irreversible nerve and brain damage.

Immune Dysfunction: Impaired methylation processes resulting from B vitamin deficiencies can weaken the immune system, making individuals more susceptible to infections and chronic diseases.

Oxidative Stress, Inflammation, and Impaired Detoxification: Depletion of a powerful antioxidants like glutathione (which relies on proper methylation) due to alcohol-induced nutrient deficiencies can lead to impaired detoxification, increased oxidative stress and inflammation, contributing to the development of various chronic conditions, including cardiovascular disease, liver disease, and cancer. (18)

Gut dysfunction: Excessive alcohol consumption can lead to dysbiosis, characterized by an imbalance between beneficial and harmful bacteria in the gut. This dysbiosis can contribute to digestive disorders such as gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and leaky gut syndrome. Nutrient absorption is compromised in a damaged gastrointestinal tract, further exacerbating nutrient deficiencies.

Gut-Brain Axis Dysfunction: The gut-brain axis, a bidirectional communication network between the gut and the brain, plays a crucial role in regulating mood, behavior, and cognitive function. Alcohol-induced gut dysfunction can disrupt this communication pathway, contributing to mood disorders such as anxiety and depression. Imbalances in gut microbiota and increased intestinal permeability can lead to the production of neuroactive compounds and inflammatory cytokines that affect brain function and mental health. (19)

Increased Toxicity: Alcohol, when consumed, is metabolized in the liver, where it breaks down into a highly toxic substance called acetaldehyde. This compound is far more harmful than alcohol itself and is classified as a probable carcinogen. Acetaldehyde can cause oxidative stress, damaging cells and tissues throughout the body. It impairs DNA repair, weakens the immune system, and promotes inflammation, which can accelerate aging and increase the risk of liver disease, certain cancers, and neurological issues.
Additionally, acetaldehyde contributes to the classic symptoms of a hangover, as it disrupts normal cellular function and contributes to dehydration, headaches, and nausea.
Reducing alcohol intake can minimize acetaldehyde exposure, supporting healthier aging, cellular function, and longevity. (20)

Addressing Alcohol-Induced Nutrient Deficiencies

To mitigate the effects of alcohol-induced nutrient deficiencies and promote overall health and well-being, individuals can take several proactive steps:

Limit Alcohol Consumption: Moderation is key when it comes to alcohol intake. Limiting consumption to 2 drinks per week can help reduce the risk of nutrient depletion and associated health issues. A recent study demonstrated that abstaining from alcohol for a month had a range of health benefits such as better energy and concentration, improved sleep, weight loss, and generally improved health. (21)

Optimize Nutrition: Focus on consuming a balanced diet rich in whole foods, including fruits, vegetables, lean proteins, and whole grains. Incorporate foods high in B vitamins, such as leafy greens, legumes, nuts, and seeds, to support neurological health and methylation processes.

Supplementation: In many cases of alcohol use, supplementation may be necessary to address existing nutrient deficiencies. Consult with your functional medicine doctor to determine the appropriate supplementation regimen based on individual needs and health goals.

Support Detoxification: Enhance detoxification pathways by supporting liver health with nutrient-rich foods, adequate hydration, and targeted supplements such as milk thistle and N-acetylcysteine (NAC). (22, 23)

Seek Professional Guidance: If you or someone you know is struggling with alcohol overuse, dependence, or addiction, seeking professional guidance from a team of healthcare providers such as an addiction specialist, psychotherapist, acupuncturist, functional medicine doctor is essential to address the direct and underlying causes.
These professionals can assess your individual needs and develop a personalized treatment plan that may include acupuncture along with other supportive therapies.
By taking a proactive approach to addiction treatment and seeking comprehensive care, individuals can increase their chances of successful recovery and achieve long-term sobriety.

Acupuncture: Acupuncture, an ancient practice rooted in Traditional Chinese Medicine (TCM), can benefit health issues related to alcohol by improving digestive and liver function, supporting detoxification, and reducing stress and mental/emotional issues, the very reason you may reach for a drink. (24, 25, 26, 27)
Furthermore, acupuncture has gained recognition for having a strong therapeutic effect in the treatment of chemical dependency and addiction, including alcohol. (28, 29)
