Sodium, potassium and magnesium when intake drops

Answering the question post #4 raises rather than the one it answers.

Fluid intake and electrolyte intake are separate questions and drinking more water alone can make a dilutional problem worse.

I would put a moderate confidence on that and no more.

Where there is a genuine question, a measurement answers it and a supplement does not. Blood tests for the common electrolytes are routine and cheap.

The disagreement above is smaller than it looks once the terms are fixed.

Baseline measurements before a substantial change in intake give you something to compare against, and almost nobody has them.

Someone will know this better than I do and I hope they say so.

Post #20 answers the question as asked. The question underneath it is different.

Sodium: losing weight involves losing some sodium. Electrolyte drinks or salty foods help maintain sodium balance. Very low sodium intake on these compounds raises orthostatic symptoms risk.

I am confident about the direction and much less about the magnitude.

Confirming post #33 from a second method, which matters more than confirming it from a second person.

Summarising the sodium thread so far, since it is long and the answer is buried: the first reply has the method, the fourth has the correction to it, and the rest is people agreeing at length.

Constipation and hydration: dehydration makes constipation worse. Increasing fluid intake is the first intervention for constipation alongside other measures.

The literature is thinner on this than the confidence in the thread implies.

Reduced intake reduces electrolyte intake alongside everything else, which is the mechanism behind most of what gets attributed to the compound here.

Reading back through the sodium threads from last year, the same three questions come up every time and only one of them has ever been answered properly. That seems like a documentation gap rather than a knowledge gap.
