Still can’t tolerate magnesium… could this be a sodium/potassium issue?

Hey everyone, I’m dealing with magnesium intolerance for a long time now and I’m still not getting anywhere with it.

I thought it was a B-vitamin issue at first. I reacted badly to B1, then realized B6 might be low (especially because I have copper toxicity). After starting P5P things got a bit easier and I can handle benfotiamine better.

But the magnesium intolerance itself hasn’t improved.

I also thought it might be calcium, but whenever I take extra calcium I feel worse — more flat, depressed, and just generally bad. So now I’m starting to suspect the problem might actually be sodium or potassium.

For context:

I eat around 5–6 grams of potassium per day and I weigh 113 kg.

I salt my food well, but my sodium blood test was on the low end of normal.

I’m also following a B12 protocol, and B12 + B1 both increase potassium needs.

So now I’m wondering:

•	Is it possible that some people just need more potassium than that?

•	Or is this more likely a sodium issue?

•	Is it safe to increase potassium when I’m not sure about sodium?

•	Should I raise both at the same time?

•	Is it okay to take more sodium than I’m already getting?

I’m basically trying to figure out whether this whole magnesium intolerance thing is actually coming from a messed-up sodium/potassium balance that got worse after starting B12.

Any experiences or thoughts would really help.
