Vitamin B6 is crucial in maintaining overall health, influencing everything from brain function to immune support. A deficiency in this vital nutrient can lead to various health issues, including mood changes, irritability, and weakened immune response.
Recognizing the symptoms and finding practical solutions is essential for maintaining wellness. The Eating Enlightenment Food Journal App can be valuable in this journey, helping individuals track and manage their cravings, emotional eating, and binges.
By providing insights into eating patterns, the app empowers users to understand and address their dietary habits more effectively.
What are the Causes of Vitamin B6 Deficiency?
Many different things can cause someone to become Vitamin B deficient. One of the most common causes is not getting enough of the vitamin in their diet.
This can happen if someone does not eat enough foods rich in Vitamin B or has a medical condition that prevents their body from absorbing the vitamin properly.
Another common cause of Vitamin B deficiency is alcoholism.
People who drink excessive amounts of alcohol are more likely to become deficient in some vitamins, including Vitamin B.
Alcoholism can cause damage to the liver, which is responsible for processing and storing many vitamins and minerals. This can lead to a Vitamin B deficiency.
Certain medications can also cause Vitamin B deficiency.
These include diuretics, anticonvulsants, and isoniazid.
People who take these medications regularly may need to supplement with Vitamin B to prevent deficiency.
Heart disease
Crohn’s disease and celiac disease are also conditions that can lead to Vitamin B deficiency.
This is because these diseases can damage the intestines, making it difficult for the body to absorb other B Vitamins properly.
As you know, Vitamin B is water-soluble, which means that it is not stored in the body. If someone is not getting enough Vitamin B, they can become deficient very quickly.
Premenstrual syndrome (PMS)
Vitamin B deficiency can also be caused by premenstrual syndrome (PMS). This is because the body’s vitamin B stores are depleted during the luteal phase of the cycle.
Pregnant women are also at risk for B Vitamin deficiency. During pregnancy, the body’s Vitamin B stores are used to support the growing baby.
Rheumatoid arthritis
Vitamin B deficiency can also be caused by rheumatoid arthritis.
This is because the inflammation associated with this condition can damage the intestines and make it difficult for the body to absorb Vitamin B.
Fatigue

One of the most common symptoms of Vitamin B deficiency is fatigue. This can be caused by a number of different things, including anemia, which occurs when there are not enough healthy red blood cells in the body.
Fatigue is also one of the most difficult health conditions because when you’re out of energy, you don’t know where you’re going.
Red blood cells are responsible for carrying oxygen to the tissues and organs.
When there are not enough red blood cells, the body does not get enough oxygen, which can lead to fatigue.
Nerve Function
Vitamin B deficiency can also cause problems with nerve function. Vitamin B is necessary for the proper development of the nervous system.
People deficient in Vitamin B may experience tingling or numbness in their hands and feet, problems with balance, and muscle weakness.
Depression
Vitamin B deficiency can also cause mood swings and depression. This is because Vitamin B is involved in the production of serotonin, a chemical that helps improve mood.
Vitamin B deficiency can also affect memory and brain function. This is because Vitamin B is involved in the production of dopamine, a chemical that helps regulate mood and cognition.
Nausea and vomiting during pregnancy (morning sickness)
Nausea and vomiting during pregnancy are commonly referred to as “morning sickness.” Morning sickness can occur in the first trimester of pregnancy and is typically caused by a combination of hormones and Vitamin B deficiency.
Vitamin B is essential for the proper development of the nervous system.
When a pregnant woman is deficient in B Vitamins, her baby’s nervous system may not develop properly. This can lead to many problems, including birth defects, mental retardation, and cerebral palsy.
Tardive dyskinesia
Tardive dyskinesia is a condition that is characterized by involuntary movements of the face, tongue, and extremities.
Several different things can cause this condition, but it is most commonly associated with the use of antipsychotic medications.
Antipsychotic medications work by blocking dopamine receptors in the brain.
Carpal tunnel syndrome
Carpal tunnel syndrome is a condition characterized by pain, numbness, and tingling in the hands and wrists. It is caused by compression of the median nerve.
Vitamin B deficiency has been linked to carpal tunnel syndrome. Vitamin B is involved in the production of myelin, a substance that helps to protect the nerves.
When there is a Vitamin B deficiency, the myelin does not develop properly, which can lead to pain in the median nerve.
Age-related macular degeneration (AMD)

Age-related macular degeneration causes vision loss and is the leading cause of blindness in people over the age of 60.
Vitamin B supplements can help to prevent or slow the age-related macular degeneration.
What is pyridoxine deficiency?
Pyridoxine deficiency is a condition characterized by Vitamin B deficiency. Vitamin B is important for the proper function of the nervous system, and pyridoxine is one of the most important forms of B Vitamins.
Pyridoxine deficiency can cause several different problems, including birth defects, mental retardation, and cerebral palsy.
Precautions
Vitamin B supplements should be taken with caution.
Supplements can interact with several different medications, so it is important to speak to a doctor before taking any Vitamin B supplements.
Vitamin B12 is the only form of Vitamin B stored in the body, and it is impossible to overdose on Vitamin B12.
Pregnant women should speak to their doctor before taking any Vitamin B supplements, as too much Vitamin B can lead to birth defects.
If you are worried about a possible vitamin deficiency, you should order an online vitamin deficiency blood test for peace of mind. Read about the best blood tests for vitamin deficiency here.
How to Take It?
So, how do you take the supplements? Vitamin B supplements are available in various forms, including tablets, capsules, and liquids.
Vitamin B12 is only available in injectable form. These injections are usually given intramuscularly (into the muscle) or subcutaneously (under the skin).
I highly recommend checking with a doctor before proceeding any further, but I also acknowledge that if you want to take supplements at home, technically, there’s nothing wrong with it. It not only helps you with vitamin B6 deficiency but also with your immune system.
What are the foods that can help?
As you know, I mostly encourage people to eat good foods that are healthy and rich in vitamins. I believe food can be a wonderful source of recovery.
Some different foods can help to prevent or treat Vitamin B deficiencies. If you want to get started, here are a few of them:
- Liver
- Kidney
- Eggs
- Milk
- Cheese
- Whole grains
- Legumes
- nuts and seeds.
