Vitamin B12 is critical for healthy nerve function and the production of DNA. It’s also necessary for the development of red blood cells, which help carry oxygen throughout your body.

When you don’t get enough of this vitamin, you can develop a deficiency that can cause a variety of symptoms.

Here’s a quick test to help you determine if you might have a B12 deficiency. Keep in mind, this is just a quick test and should never replace the advice of a doctor.

1. Are You Vegan or Vegetarian?

If you’ve cut meat out of your diet, you’re at a higher risk for a vitamin B12 deficiency. That’s because vitamin B12 is found almost exclusively in animal products.

If you’re avoiding all animal products, you need to find alternate sources of the vitamin.

2. Have You Recently Had Gastric Surgery?

Patients who have had gastric bypass surgery have a higher risk of a B12 deficiency because the surgery can limit their ability to absorb the vitamin.

If you’ve had this type of surgery, talk to your doctor about whether or not you need to take a B12 supplement.

3. Are You Over 50?

As you age, your body’s ability to absorb vitamin B12 declines. This means that people over 50 are at a higher risk for developing a deficiency. If you’re over 50, talk to your doctor about whether or not you need to be screened for a deficiency.

4. Do You Have Digestive Issues?

If you suffer from digestive issues like Crohn’s disease or celiac disease, you may not be able to absorb the vitamin B12 your body needs. This can lead to a deficiency over time.

5. Do You Suffer From Anemia?

Anemia is a condition where you don’t have enough iron in your blood. This condition can also affect your body’s ability to absorb vitamin B12.

6. Do You Lack Energy?

Lack of energy is one of the most common symptoms of a B12 deficiency. If you’re finding that you’re tired all the time, it may be worth talking to your doctor about getting tested for the deficiency.

7. Are You Experiencing Numbness or Tingling?

If you’re experiencing numbness or tingling in your hands or feet, it may be a sign of a vitamin B12 deficiency. This is because B12 is important for healthy nerve function.

8. Do You Have Dizziness or Balance Issues?

Vitamin B12 deficiency can cause issues with balance and dizziness. This is because the vitamin is important for healthy brain function.

9. Are You Experiencing Mood Swings or Depression?

10. Do You Experience Memory Loss or Confusion?
