Can vitamin b12 damage your liver?

I was told I need to increase my Vitamin B12 intake, but my friend warned me about taking too much. Can high levels of Vitamin B12 actually damage your liver? I'm a bit confused.

I was prescribed B12 tablets last week and I'm honestly so worried about my liver. Has anyone else felt mild nausea or heavy feelings after taking them, or is it just my anxiety acting up? Let me know if this is normal.

Vitamin B12 is actually stored in the liver naturally, and it doesn't cause any damage. If you are taking high doses, just get a simple liver function test done next time you do your blood work. It's a cheap and easy way to stay sure.

I have been taking high-dose B12 for nerve issues for two years. My doctor told me it's a water-soluble vitamin, so whatever your body doesn't need just gets flushed out, and it's completely safe for the liver. Just don't self-medicate without a doctor's dose advice.

Managing my thyroid means I get my liver and vitamin levels checked every six months. B12 is actually beneficial for liver health, but you should always run regular tests to monitor your levels. Keep your doctor updated on all your supplements.

B12 is highly unlikely to cause liver toxicity, but taking extremely high doses without knowing your actual levels is never a good idea. Please get a simple blood test done and consult your doctor to ensure you are taking the correct safe dosage.

I completely understand why you'd worry about how pills affect your body. Unlike heavy medicines, B12 is very gentle and actually helps your liver function well. Still, always consult your physician before taking any supplements long-term.
