About this test

For healthy nerves and red blood cells

Vitamin B12 is important for brain health, blood cell production and proper nerve function. Your body doesn’t naturally produce vitamin B12, it comes from animal products like fish, meat, and dairy. Vitamin B12 deficiency is not uncommon and many people have trouble absorbing this vitamin, especially older adults and people with intestinal disorders such as coeliac disease and Crohn’s disease. Vegans and individuals on restricted diets, and people with diabetes are at greater risk of having a low vitamin B12 blood test result.
