Vitamin B12 helps the body make healthy red blood cells. Red blood cells carry oxygen throughout the body. When the body does not have enough B12, red blood cells may not develop normally.
This can contribute to a type of anemia that may cause fatigue, weakness, pale skin, shortness of breath, dizziness, or a fast heartbeat. Because these symptoms can overlap with other conditions, blood testing is important.
B12 deficiency and pernicious anemia
One condition linked to B12 deficiency is pernicious anemia. This happens when the body lacks enough intrinsic factor, a substance needed to absorb vitamin B12 properly. Some patients with pernicious anemia may need long-term B12 replacement, often through injections or another provider-directed method.
B12-related anemia may also occur when someone does not get enough B12 in the diet or cannot absorb it well due to medical conditions, stomach surgery, intestinal surgery, or certain medications.
Why the cause of anemia matters
Anemia can have many causes. Healthcare providers usually rely on blood tests to determine whether B12 is involved and whether another cause needs treatment.
When B12 deficiency is confirmed, replacement can be very helpful. The best form depends on the patient’s medical situation, absorption ability, and provider recommendation. Patients with a valid prescription can learn more about the Pill Pals B-12 Kit – Subcutaneous Cyanocobalamin B12 Injection.

Medication Safety Note
Do not assume anemia is caused by B12 deficiency. Iron deficiency, folate deficiency, chronic disease, bleeding, kidney disease, and other conditions can also cause anemia. A healthcare provider should determine the cause before treatment.
