Vitamin B6, known as pyridoxine, is vital in maintaining overall health. This water-soluble vitamin supports numerous bodily functions, including metabolism, brain development, and immune function. Despite its importance, many people must know the risks and causes of vitamin B6 deficiency.
Recognizing these causes is crucial for preventing and addressing vitamin B6 deficiency. Awareness and proactive management can help maintain optimal health. With the right knowledge, ensuring adequate intake and avoiding the complications associated with deficiency is possible.
What is vitamin B6 deficiency due to?
Understanding the common causes of vitamin B6 deficiency helps address and prevent this health issue effectively. Here’s a closer look at the primary factors that can lead to a deficiency in this essential nutrient:
1. Poor diet
A poor diet is a leading cause of vitamin B6 deficiency [1]. Many people rely heavily on processed foods, which often lack essential nutrients, including vitamin B6.
Fast food, packaged snacks, and sugary drinks may be convenient, but they do not provide the vitamins and minerals your body needs to function properly.
To maintain adequate vitamin B6 levels, it’s crucial to incorporate a variety of nutrient-rich foods into your diet. Some excellent sources of vitamin B6 include:
- Turkey
- Chicken
- Fish, including salmon, tuna, and other varieties
- Potatoes
- Sweet potatoes
- Other vegetables high in starch
- Bananas
- Avocados
A balanced diet that includes these foods helps ensure you get enough vitamin B6. Neglecting this aspect of nutrition can lead to a deficiency, which can affect your metabolism, brain function, and immune system.
Making conscious food choices can support your overall health and prevent vitamin B6 deficiency.
2. Chronic diseases
Chronic diseases can significantly contribute to vitamin B6 deficiency, impacting the body’s ability to absorb and utilize this essential nutrient effectively. Conditions such as kidney and liver diseases are particularly influential in this regard.
- Kidney disease: Patients with chronic kidney disease often experience vitamin B6 deficiency because the kidneys are crucial in processing and excreting nutrients [2]. Dialysis, a common treatment for advanced kidney disease, can also deplete vitamin B6 levels.
- Liver disease: The liver is vital for nutrient metabolism, including vitamin B6. Liver diseases like cirrhosis or hepatitis can impair this function, leading to lower levels of the vitamin in the body.
Addressing vitamin B6 deficiency in individuals with chronic diseases often requires a tailored approach, including dietary adjustments and supplements.
3. Malabsorption disorders
Malabsorption disorders are a significant cause of vitamin B6 deficiency. These conditions impair the digestive system’s ability to absorb nutrients effectively, leading to various deficiencies, including vitamin B6.
- Celiac disease: This autoimmune disorder damages the small intestine when gluten is consumed, hindering nutrient absorption. People with celiac disease often struggle to absorb vitamins and minerals from their diet, including vitamin B6.
- Crohn’s disease: As a kind of inflammatory bowel disease (IBD), Crohn’s disease can impede nutrition absorption by causing inflammation in the digestive tract. The gut lining is damaged as a result of the inflammation, which lowers the effectiveness of nutrient absorption.
- Ulcerative colitis: Another form of IBD, ulcerative colitis, affects the colon and rectum, leading to similar absorption issues. The chronic inflammation associated with this condition can result in poor nutrient absorption, including vitamin B6.
Managing vitamin B6 deficiency in individuals with malabsorption disorders typically involves a multifaceted approach. This may include a specialized diet that avoids trigger foods (such as gluten in celiac disease), nutritional supplements, and medications to control inflammation.
4. Alcoholism
Alcoholism is a major contributor to vitamin B6 deficiency. The body’s capacity to absorb and utilize nutrients, including vitamin B6, is hampered by excessive alcohol use [3].
Additionally, alcoholics often have poor dietary habits, further exacerbating nutrient deficiencies. Chronic alcohol use damages the liver, which is crucial for nutrient processing, leading to even lower levels of vitamin B6.
To address this, individuals struggling with alcoholism should seek medical help to reduce alcohol intake and improve their diet, focusing on nutrient-rich foods and possibly incorporating vitamin B6 supplements as advised by healthcare professionals.

5. Medications
Certain medications can lead to vitamin B6 deficiency by interfering with the body’s ability to absorb or metabolize this essential nutrient. These interactions often require close monitoring and adjustments to maintain adequate vitamin B6 levels.
- Isoniazid: Used to treat tuberculosis, isoniazid can inhibit the activity of vitamin B6 in the body. Patients on long-term isoniazid therapy may need to take vitamin B6 supplements to prevent deficiency.
- Hydralazine: This medication for high blood pressure can also deplete vitamin B6 levels. Patients prescribed hydralazine should monitor their vitamin B6 status regularly to avoid potential deficiency-related issues.
- Oral contraceptives: Some birth control pills can lower vitamin B6 levels. Women taking these contraceptives might need to increase their intake of vitamin B6 through diet or supplements.
- Antiepileptic drugs: Medications such as phenobarbital and phenytoin, used to control seizures, can interfere with vitamin B6 metabolism. Individuals on these medications should discuss their nutrient needs with their healthcare provider.
Addressing vitamin B6 deficiency caused by medications involves dietary changes and supplementation guided by healthcare professionals.
What happens when your vitamin B6 is low?
Vitamin B6 deficiency can manifest through various symptoms, affecting both physical and mental health. Here are some common signs to watch for:
Physical symptoms
- Anemia: A deficiency can lead to microcytic anemia, characterized by small red blood cells and reduced oxygen transport.
- Dermatitis: Skin conditions, including rashes, scaling, and cracking, especially around the eyes, nose, and mouth.
- Glossitis: Inflammation of the tongue, causing pain and swelling.
- Peripheral neuropathy: Tingling, numbness, or pain in the hands and feet due to nerve damage.
Mental health symptoms
- Depression: Low levels of vitamin B6 are linked to mood disorders.
- Confusion: Cognitive impairment and difficulty concentrating.
- Irritability: Increased irritability and mood swings.
Immune system symptoms
- Increased susceptibility to infections due to impaired immune function.
Recognizing these symptoms early can lead to timely intervention and treatment, preventing more severe health issues.
How do you prevent vitamin B6 deficiency?
Adequate vitamin B6 levels are essential for maintaining overall health. Addressing a deficiency involves dietary changes, supplementation, and lifestyle adjustments. Here’s a comprehensive guide to treating and preventing vitamin B6 deficiency:
1. Recommended supplements
Supplements can be crucial in addressing vitamin B6 deficiency, especially when dietary intake alone isn’t sufficient. Here’s what you need to know about vitamin B6 supplements:
