Can too much b12 cause hair loss?

My doctor recommended B12 supplements as my levels were low, and I've been taking them diligently for a few months now. However, my hair fall seems to have actually increased since then. I'm wondering if too much B12 could be the problem?

Actually, my health tracker app shows B12 is water-soluble, so excess usually gets flushed out in urine. Still, crazy high doses can sometimes trigger skin breakouts or hair thinning indirectly by messing with other nutrients. Better to track your exact blood levels first.

At my age, half my hair is already gone just by looking at my monthly bills! Honestly though, B12 is usually safe, but taking too much of any supplement without a doctor's nod is just asking for trouble. Keep the pills aside and have some simple home-cooked food.

Excuse me, I am also facing some hair fall recently and was thinking of taking B12. Does it really cause more hair fall if we take too much? Please let me know if anyone got tested by a doctor for this.

Bro, I was taking high-strength B12 injections for my fatigue last year and my hair started thinning like crazy. My doctor told me to stop immediately because excessive levels can trigger imbalances. Once I stopped, my hair fall went back to normal.

Yes, I agree with others that overdoing supplements is never good. It is always safer to get a simple blood test done before buying these over-the-counter B12 tablets.

Please don't believe random Google searches or internet forums for your hair issues. Some say B12 causes hair loss, others say it cures it. Just go to a proper dermatologist and get your scalp and blood work checked professionally.

Haan bhai, log sote hain jitna vitamin kha lo utna accha h, par aisa nahi hota na. Excess B12 se body ka balance bigad sakta hai jo hair loss kara de. Faltu me dawayi mat khao, doc se check karwa lo ek baar.
