Vitamin B12 is essential, but can you have too much? While B12 is water-soluble, meaning your body typically excretes excess amounts, consistently high B12 levels can sometimes indicate underlying health concerns.
What's considered 'high'? This varies depending on the lab, but generally, it's above the upper limit of the normal range. While rare, high B12 could be linked to liver or kidney problems, certain cancers (like leukemia), or autoimmune disorders.
Don't panic if you see a high result! It's crucial to consult your doctor. They'll review your medical history, medications, and potentially order further tests to determine the cause. Self-treating based solely on lab results is never recommended. Finding the root cause is key to maintaining your health.
