Don't Let a Vitamin B Deficiency Hold You Back

Vitamin B complex is a group of eight water-soluble vitamins that are essential for many bodily functions, including energy production, brain function, and cardiovascular health.



Vitamin B Complex: What You Need to Know

The eight vitamins in the B complex are:

  • Thiamine (B1)

  • Riboflavin (B2)

  • Niacin (B3)

  • Pantothenic acid (B5)

  • Pyridoxine (B6)

  • Biotin (B7)

  • Folate (B9)

  • Cobalamin (B12)

These vitamins work together to help the body:

  • Convert food into energy

  • Make and repair DNA

  • Produce red blood cells

  • Maintain a healthy nervous system

  • Keep the skin, hair, and nails healthy

  • Vitamin B12 can help improve your mood. Vitamin B12 is essential for the production of serotonin, a neurotransmitter that helps regulate mood. A deficiency in vitamin B12 can lead to depression, anxiety, and other mood disorders.

  • Folate can help prevent cancer. Folate is important for DNA synthesis and repair. A deficiency in folate has been linked to an increased risk of certain types of cancer, such as breast cancer and colorectal cancer.

  • Vitamin B6 can help boost your immune system. Vitamin B6 is involved in the production of white blood cells, which help fight infection. A deficiency in vitamin B6 can lead to a weakened immune system and an increased risk of infection.

  • Biotin can help improve your skin and hair health. Biotin is important for the production of keratin, a protein that makes up your skin and hair. A deficiency in biotin can lead to dry skin, brittle hair, and other problems.

  • Niacin can help lower your cholesterol. Niacin helps to increase the production of HDL cholesterol, the "good" cholesterol. A deficiency in niacin can lead to high cholesterol levels, which can increase your risk of heart disease.


For pregnant individuals


In addition to helping to prevent birth defects and other problems, B vitamins can also help pregnant and breastfeeding women manage their energy levels and cope with the stress of pregnancy. They may also help to reduce the risk of developing preeclampsia, a serious pregnancy complication that can cause high blood pressure, seizures, and other problems.


If you are pregnant or breastfeeding, it is important to talk to your doctor about getting enough B vitamins. They can help you determine if you need to take a supplement.

There are a number of diseases that can affect the utilization of vitamin B complex. Some of these diseases include:

  • Celiac disease: Celiac disease is an autoimmune disorder that damages the small intestine when gluten is ingested. Gluten is a protein found in wheat, barley, and rye. When people with celiac disease eat gluten, their immune system attacks the small intestine, causing inflammation and damage. This damage can make it difficult to absorb nutrients, including vitamin B complex.

  • Crohn's disease: Crohn's disease is a chronic inflammatory bowel disease that can affect any part of the digestive tract. Like celiac disease, Crohn's disease can damage the small intestine and make it difficult to absorb nutrients.

  • Pancreatic insufficiency: The pancreas is a gland that produces enzymes that help to digest food. In pancreatic insufficiency, the pancreas does not produce enough enzymes, which can lead to malabsorption of nutrients, including vitamin B complex.

  • Alcoholism: Alcoholism can damage the liver, which is responsible for storing and processing vitamins. As a result, people who abuse alcohol are at risk of vitamin B deficiency.

  • Inflammatory bowel disease: IBD is a group of chronic conditions that cause inflammation in the digestive tract. IBD can affect the small intestine, which is where vitamin B complex is absorbed. As a result, people with IBD are at risk of vitamin B deficiency.

  • Infections: Some infections, such as HIV/AIDS, can damage the gut and make it difficult to absorb nutrients, including vitamin B complex.

  • Medications: Some medications, such as metformin, can interfere with the absorption of vitamin B complex.

Most common symptoms of vitamin B deficiency

  • Fatigue: One of the most common symptoms of vitamin B deficiency is fatigue. This is because the B vitamins are involved in energy production.

  • Anemia: Anemia is a condition in which the body does not have enough red blood cells. This can cause symptoms such as fatigue, shortness of breath, and pale skin.

  • Depression: Vitamin B deficiency can also lead to depression. This is because the B vitamins are involved in the production of serotonin, a neurotransmitter that helps regulate mood.

  • Diarrhea: Diarrhea is another common symptom of vitamin B deficiency. This is because the B vitamins are involved in the metabolism of carbohydrates.

  • Neurological problems: Vitamin B deficiency can also lead to neurological problems, such as numbness and tingling in the hands and feet, and difficulty walking.

  • Skin problems: Vitamin B deficiency can also lead to skin problems, such as dermatitis and seborrheic dermatitis.

The specific symptoms of vitamin B deficiency can vary depending on the specific vitamin that is deficient. For example, vitamin B1 deficiency can cause beriberi, which is a condition that affects the nervous system and the cardiovascular system. Vitamin B12 deficiency can cause pernicious anemia, which is a type of anemia that can lead to neurological problems.

If you are experiencing any of these symptoms, it is important to see a doctor to get tested for vitamin B deficiency. The doctor will likely order a blood test to check your levels of the B vitamins.


If you are found to be deficient in one or more of the B vitamins, the doctor may recommend that you take a supplement. The type of supplement that you need will depend on the specific vitamin that you are deficient in.


It is important to note that vitamin B deficiency can be serious, so it is important to get treatment if you think you may have it. Treatment can help to prevent complications and improve your overall health.

Here are some tips to help prevent vitamin B deficiency:

  • Eat a balanced diet that includes a variety of foods that are rich in B vitamins.

  • If you are vegan or vegetarian, make sure that you are getting enough B12 from fortified foods or supplements.

  • If you are pregnant or breastfeeding, talk to your doctor about getting enough B vitamins.

  • If you have any underlying health conditions, talk to your doctor about whether you are at risk for vitamin B deficiency.


It is important to see a doctor if you are experiencing symptoms of vitamin B deficiency, as these symptoms can also be caused by other conditions. Your doctor can rule out other possible causes and make a diagnosis.
