Dr Oz: Do You Need More B12?

Vitamin B12 Deficiency: Dr Oz

Are you getting enough Vitamin B12? Dr Oz and experts discussed symptoms and causes of Vitamin B12 Deficiency, which affects 40% of adults.


Are you tired all the time? Do you feel like you’re always forgetting things or just seem depressed for no particular reason? One possible explanation is a lack of Vitamin B12, which affects an estimated 40% of people.

B12 is vital in guarding your immune system against disease. It helps you feel young as the body produces more red blood cells. You can get it naturally in foods you eat or as an injection, which begs the question: why are so many of us (up to 47 million Americans) not getting the Vitamin B12 our bodies crave?

In some instances, a lack of B12 could be mistaken for symptoms of other medical issues, like Alzheimer’s Disease, strokes, or clinical depression. Before this episode taped, the audience submitted to medical testing. Dr Oz revealed that 1/3 of his audience was deficient in Vitamin B12.


Dr Oz: Vitamin B12 & Anemia

Dr David Katz said that Vitamin B12-deficient patients are at a greater risk for anemia. The body won’t produce DNA properly if it doesn’t have the vital B12 it needs. That means cells aren’t replaced as needed. Part of the deficiency is caused by the increased percentage of processed foods in our diets. Another contributing factor is a rise in prescription drug use, which can interfere with B12 levels.

Registered dietician Kate Geagan said that this is a growing concern, because a low Vitamin B12 level could cause permanent damage to your health. However, this is a uniquely American problem. These statistics aren’t seen in other industrialized countries like Japan.

Kate explained that cultural differences in diet are one factor. In Japan, seafood is much more integral to the diet, and it’s naturally loaded with B12. Comparatively, the Japanese also have fewer prescription medications as well.

Dr Oz: Vitamin B12 Deficiency Symptoms

Ask yourself these questions to see if you could have low Vitamin B12.

  • Is your energy low?
  • Do you have unexplained mood swings?
  • Are you having trouble with memory or concentration?
  • Do you have numb or tingling feet or fingers?
  • Is your tongue inflamed?

Answering yes to just one of the questions means you could be Vitamin B12 deficient, according to Dr Oz.

What Causes Vitamin B12 Deficiency?

Here are some of the contributing factors mentioned by Dr Oz and his guests.

  • Medication – Common medications such as Aspirin, heartburn medication (proton pump inhibitors) and Folic Acid can cause issues with Vitamin B12. Fortified Folate can also accelerate Vitamin B12 deficiency, leading to irreversible symptoms.
  • Stomach Acid – The stomach’s cells actually change with age, because our stomachs produce less gastric acid. About 30% of adults over age 50 aren’t producing enough stomach acids. This is needed to help process proteins as well as B12.
  • Animal Protein – Chicken and seafood are two staples in Japan, but they aren’t nearly as popular in the US. These natural animal proteins are often loaded with B12.
  • Alcohol – Drinking alcohol can wreak havoc on your gastrointestinal function, sometimes leading to stomach atrophy. Moderate drinking can be safe, but excessive drinking can lead to various health issues.
