Biomarkers
Vitamin B12
Vitamin B12 is essential for red blood cell production and nerve function. It can be obtained from food, supplements, and fortified foods. A deficiency may lead to anaemia or nerve damage. Normal B12 levels range from 200 to 900 ng/mL. If levels are low, a doctor may recommend B12 supplements or fortified foods.
Additionally, Folate and Vitamin D may be assessed alongside Vitamin B12 in a test, as they are related in terms of overall health and nutrient balance.
Folate B12
A Folate, folic acid, or Vitamin B test measures the serum levels of folate in the blood. Folate is essential for the healthy production and regulation of red blood cells. A typical folate level is 2.7 to 17 ng/mL. If the result is lower than 2.7 ng/mL, it may indicate a folate deficiency.
Vitamin D
Vitamin D is essential for bone and muscle health, as well as overall immune function. It can be obtained from food, supplements, and fortified foods. A deficiency in vitamin D may lead to osteoporosis or muscle weakness. The typical vitamin D level is between 20 to 50 ng/mL. If your level is low, a doctor may recommend taking a vitamin D supplement or consuming fortified foods to restore optimal levels.

Additional Information
If you are displaying symptoms of a vitamin deficiency, such as fatigue, muscle weakness, bone pain, or rashes, your doctor will likely recommend a blood test to measure vitamin levels and identify any deficiencies.
If a deficiency is found, your doctor may suggest supplements to correct it and recommend dietary changes to include more foods rich in the missing vitamins. Vitamin deficiencies can lead to health issues like anemia, osteoporosis, fatigue, and dizziness.
To prevent deficiencies, aim for a balanced diet full of fruits and vegetables and consider taking a daily multivitamin. If you have concerns, consult your doctor or a registered dietitian to create a dietary plan tailored to your needs. Vitamin deficiencies are common but preventable with proper nutrition.
