The studies weren't using regular forms of potassium. Also, like
this one, the reason the 'slow-potassium' inhibited B12 --
just slightly -- was because it interfered with it
in the small intestine. Not sublingually
Thank you for taking a look, and explaining.
Right now, I'm actually wondering about sodium. My diet isn't really normal. I eat almost totally whole foods. So the only sodium I get is from putting salt on my food, which I do.
But all of this potassium, I mean how does that affect sodium? I drank potassium throughout the night (just plain powder in water). Then I drank another 450 mg in water first thing in the morning. I guess it could have been in my mind but I started having chest pain (I have no heart conditions of which I'm aware and I've had many tests). So I stopped.
About an hour and a half later, I was feeling more and more tired. My BP was very low and my heart rate was high. I've been associating this with low potassium bc those are listed on the Cleveland Clinic website as symptoms of severe low potassium. (Sometimes my HR is high but more often very low, usually with extreme tiredness, and sometimes muscle twitching, when I decide to take potassium.)
This has really confused me bc normally I would think potassium would lower your BP.
Anyway, today I was even more suspicious bc I had just taken a large dose of potassium 1.5 hrs earlier, and had very little relative sodium since dinner last night. And that B12 consultant lady actually suggested sodium (I emailed her to ask if she had seen this before.) I did the elliptical machine yesterday so would have lost electrolytes that I may not have replaced, including sodium. I had real issues last night with what I thought was low potassium (BP started low then went high.)
I had no problems balancing electrolytes naturally before the B12 shots. I'm totally perplexed.
I have been assuming this is all potassium bc that's a known risk of the shots. But both low potassium and low sodium apparently can cause low BP and high HR.
I just don't know how we can possibly know without constant monitoring and testing. Or i guess the fall back would be to add sodium to every potassium drink. But then if only one or the other were out of balance, I don't see how that would work, either.
@Freddd do you have any ideas based on the cases you've seen?
