B12 Injections
When You Need B12 Support
Vitamin B12 is an essential water-soluble vitamin that plays a key role in several important body functions—including the production of DNA, red blood cells, and proper nerve function. A deficiency in B12 can lead to megaloblastic anemia, which causes fatigue, weakness, and other symptoms due to the production of abnormally large red blood cells.
You can get B12 from foods like meat, fish, eggs, dairy, nutritional yeast, and certain fortified foods. In animal products, B12 is bound to protein and must be separated by stomach acid during digestion. From there, a substance called intrinsic factor helps your body absorb it.
Some people don’t produce enough stomach acid or intrinsic factor, often due to a condition called autoimmune atrophic gastritis, and can’t absorb B12 properly. Others, such as those who’ve had gastrointestinal surgery or have certain digestive disorders, also struggle with absorption. In these cases, B12 injections are often recommended to maintain healthy levels and prevent pernicious anemia.
Who Might Benefit from Vitamin B12 Injections?
Vitamin B12 injections may be recommended for individuals who are deficient or unable to absorb enough from food. While many people get enough from their diet, deficiency is surprisingly common, especially among older adults, with studies showing up to 43% may have low levels.
You might benefit from B12 shots if you:
Follow a vegetarian or vegan diet
Have had gastric surgery
Have conditions like pernicious anemia, celiac disease, or Crohn’s disease
Are pregnant or breastfeeding
Symptoms of low B12 levels can include:
- Fatigue, muscle weakness, or dizziness
- Memory problems or confusion
- Personality or mood changes
- Tingling or numbness in hands and feet
- Pale skin, heart palpitations, or weight loss
- Constipation, low appetite, infertility, or a sore tongue
If you’re experiencing any of these, it’s important to see your doctor. A simple blood test can determine whether you’re deficient, and Dr. Flippin can guide you on whether injections or other treatments are right for you.
