What is Vitamin B12 (Vitamin B12)?
Vitamin B12 is measured as part of a cardiac panel. Your B12 is in a healthy range.
What does a high Vitamin B12 mean?
Elevated B12 is usually harmless from supplementation, but very high levels without supplementation can sometimes indicate liver disease or certain blood disorders.
What does a low Vitamin B12 mean?
Your B12 is low. Vitamin B12 deficiency causes fatigue, neurological symptoms (tingling hands/feet), and megaloblastic anemia. Common in vegetarians/vegans, the elderly, and those with absorption issues.
If markedly low: Your B12 is critically low. At this level, neurological damage — tingling, numbness, memory problems — can occur. Injections may be needed.
