What is Vitamin B12?
Vitamin B12 (cobalamin) is an essential vitamin found only in our diet, mainly in animal products, and is required for DNA and fatty acid synthesis as well as nerve health. Optimal B12 levels are thus required to maintain blood and nerve health.
What does it assess?
Vitamin B12 levels assess an individual’s status of this essential vitamin, which is crucial for nerve function, DNA synthesis, red blood cell formation, and overall cellular health. Adequate B12 levels support brain health, energy production, and the prevention of anemia.
How do I optimize my Vitamin B12 levels?
Include animal-based foods in your diet, as they are the primary natural sources of B12. Good options include fish, meat, eggs, and dairy products. These foods provide bioavailable B12, which is well-absorbed by the body.
Vitamin B12 absorption depends on adequate stomach acid and intrinsic factor production. For optimal absorption, manage conditions that may lower stomach acid.
Excessive alcohol can impair B12 absorption and storage, as it affects the liver, where B12 is stored. Limiting alcohol can help optimize your B12 levels and support liver health.
What do high and low Vitamin B12 levels mean?
Elevated vitamin B12 levels are less common and can occur from excessive supplementation. High vitamin B12 levels in the absence of supplementation may occasionally indicate liver dysfunction. Certain blood disorders or kidney disease can also elevate vitamin B12 levels.
Low vitamin B12 levels indicate a deficiency, which may be due to poor intake or absorption issues. Symptoms of vitamin B12 deficiency include fatigue, tingling or numbness, difficulty concentrating, and anemia. Left untreated, B12 deficiency can lead to nerve damage and cognitive impairments.
