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.
An increased loss of vitamin B12 is also seen in individuals with liver and kidney disease as well as alcoholism. Symptoms of a vitamin B12 deficiency can include:
- muscle weakness and stiffness
- low blood pressure
- mood disturbances
If you have a low vitamin B12 blood test result, there is evidence that supplements can boost energy, concentration, memory and mood.
