B12

What is B12?

Vitamin B12 is an important nutrient that your body needs but can't produce on its own. You get it from foods, especially meat, fish, and dairy products. B12 helps your body make red blood cells, keeps your nerves working well, and helps with DNA production.

Why is it measured?

B12 is critical for analysis of a variety of issues:

  1. Anemia Check: Low B12 levels may cause a type of anemia called pernicious anemia. This is when your body can't make enough healthy red blood cells, which can leave you feeling weak and tired.

  2. Nerve Health: Long-term B12 deficiency may lead to nerve damage, which can cause tingling and numbness in the hands and feet, balance problems, and memory difficulties.

  3. Health in Older Adults: Sometimes, older people have trouble absorbing B12, which can lead to a deficiency. Doctors often check B12 levels in older adults who are feeling weak, tired, or confused.

  4. Hormonal and Reproductive Health: Vitamin B12 has been shown to play a critical role in Hormonal Regulation, Fertility levels, and Sperm health.

How can I better understand my results?

  • Low Levels: This may mean that you are not intaking enough B12 or your body simply is not absorbing it correctly. It may be a sign of a genetic disorder as well. Low levels may result in fatigue, weakness, and other symptoms. 
  • Higher than Average levels: Higher than average levels might indicate that you are taking supplemental B12 in some form. It could, however, indicate a more serious underlying health condition.
