Vitamin Supplements for Thyroid and Cardiac Issues

Has anyone here any issues with taking supplements such as B12, Vit D3, magnesium etc, and had any adverse reaction from their heart? I've found B vitamins give me palpitations and would like to know if anyone else has had similar experiences. If so, what were you taking and how did you resolve them?

I had severe palps when on levothyroxine but not on vitamins.

Thank you.

I have palpitations whether I take vitamins or not, although hawthorn makes them less obvious.

Do you feel that vitamins improve your overall health condition?

Are you drinking Hawthorn tea or taking a supplement?

Supplement. I made all my hawthorn berries into chutney last year.

Some people cannot tolerate vits, I and a few others on here come into that group. On paper I am deficient in both B12 and vitd but taking supplements causes side effects so my conclusion is that my body is happy with them where they sit and doesn't want any more. Just because there are ranges for all these things doesn't mean we all need to fit within them, my theory anyway.

For you, are bouts of extreme fatigue common? If so, how do you manage it?

I don't suffer with extreme fatigue.

Did you ever get symptoms of b12 deficiency, like nerve damage? I had a seriously rough time with b12 and b9, but when I stopped taking them, the nerve damage followed quickly. I agree there's quite a grey area with b12.

I'm not really sure about having nerve issues- In the distant past, I realized once I stopped taking B vitamins supplement that all my skipped beats stopped happening.

Now with the onset of my current condition, (I'm not sure if it's related to thyroid, renal or ME/CFS issues. I haven't got a firm diagnosis. I often feel chest discomfort and have skipped beats.

I'm hoping that by taking Magnesium and some other supplements I can get some relief- I've just never been one to take supplements so I'm a little anxious.

I think sometimes low potassium and can cause problems. If you're anemic, and you get an influx of b12, you start making red blood cells, and that puts a strain on your electrolytes. I got horrible muscle cramps and stiffness, and I think sometimes the heart palps can come from that too.

Ideally I guess you doctor would check your electrolytes when you're symptomatic, and then advise you how to get enough, particularly magnesium and potassium.

I take supplements, but I'm not telling you to go out and take them, because they're not always safe if not taken properly.

But it's generally a good idea to eat very potassium and magnesium rich food, particularly around your b12 doses.

Yes, I was initially put on high dose methylcobalamin, before the thyroid issues were discovered, and I had very severe palpitations. I'm on lower doses now of a different form of b12, through injection, and I tolerate it much better.

I couldn't tell exactly what fixed it, because so many changes were made.

But I think it's important to have all the supporting nutrients like potassium, iron, magnesium, etc when taking b vitamins. It's best to get it through diet first if possible, and then to have a doctor monitor your levels.

I had palps prior to methylcobalamin, but on it they were much, much worse.
