B-12 Q & A

What is vitamin B-12?

Vitamin B-12 is an essential vitamin that plays a major role in maintaining good health throughout life. Although the vitamin is found naturally in foods, studies have found many people are deficient in B-12, which is essential for brain and nervous system health. Vitamin B-12 is also important for metabolism, the process the body uses to convert food to usable energy, and low levels can interfere with weight loss programs and diet. Because the body cannot synthesize vitamin B-12 on its own, supplementation can play an important role in maintaining optimal health for many patients.

What causes vitamin B-12 deficiency?

While low levels of vitamin B-12 can result from poor dietary choices, deficiency can also occur as a result of:

  • irritable bowel syndrome, inflammatory bowel disease and other diseases of the gastrointestinal tract
  • pernicious anemia, a condition that interferes with the body's ability to absorb the vitamin
  • weight-loss surgery that decreases the body's ability to absorb nutrients
  • prolonged use of heartburn medications
  • problems with the immune system
  • alcohol abuse
  • older age
  • following a vegetarian or vegan diet

What symptoms does B-12 deficiency cause?

Vitamin B-12 deficiency cause:

  • heart palpitations or irregular heartbeat
  • dizziness
  • shortness of breath
  • weakness
  • fatigue
  • diarrhea, constipation or bloating
  • vision loss
  • numbness or tingling

Vitamin B-12 deficiency can also cause anemia, a serious medical issue that can decrease the amount of oxygen reaching organs and tissues throughout the body.

Are vitamin B-12 shots better than oral supplements?

Vitamin B-12 shots are designed to be more effective than oral supplements because they deliver the vitamin directly to the bloodstream, bypassing the digestive system which can cause the vitamin to break down and lose its potency. Delivering the vitamin directly to the bloodstream is also important where nutrient absorption is an issue.

How often should I have vitamin B-12 shots?

The frequency and number of shots vary from one patient to another. Blood testing can determine if vitamin B-12 deficiency is present as well as determine the best course of treatment based on the patient's specific needs.
