Can low B12 or ferritin make you feel shaky and weak, with heart palpitations?

[BaconAddict]

Wondering if this is the culprit. I'm due on my period and most of today have felt shaky and now this evening my muscles feel very weak! Just no strength in my arms or legs at all.

Does this sound familiar to anyone else?

Low b12 made me feel awful. Very short of breath, exhausted and generally crap. Thought I was having a nervous breakdown and was relieved to find out I had a deficiency.

Watching with interest as I’m vegetarian and have had horrendous palpitations/tiredness for weeks now, plus recurrent illnesses. Doctor has booked a blood test and ecg but it’s not for 6 weeks!

@intergalacticplanetary I hope you're feeling better these days, are you on B12 injections now?

@Changethenamey I hope you get some answers! I'm doing blood tests on Friday to see where my B12 is now.

It tends to hover around 200 to 300 ish. I'm always tired but feel so bad today, I'm wondering if it's taken a nosedive.

Yes it can do, also the surge of hormones will be felt even more so because you are anemic and not in the best health.

Low ferretin yes, it's known for causing heart palpitations. When mine was low I would feel weak and my chest would ache.

Yes - exactly this. I had horrendous constant heart palpitations with my low iron and folate a few months ago. The good news is it only took a few days or Treatment for it to improve substantially.

I don't think I'm anaemic though? My haemoglovin is fine, it's on the high side.

Is it not that it can eventually turn into anaemia once the ferritin runs out?

I feel thick as a plank, but can just not understand the whole interplay between iron, B12 and vitamin D. I've got my vitamin D up to 50 after it being in the 20s for literally years, and read somewhere that upping the vit D can have some sort of knock on effect that tanks either the ferritin or B12?

Brain fog as a side effect of all these deficiencies is really unhelpful when it comes to trying to figure it all out, I must say

Haemoglobin, even

@BaconAddict it was a little while ago but I had supplements for a few months and felt sooooo much better. Was amazing how much it affected me.
