Balancing phosphorous and sodium


#1

Hey, as I’m looking at the formulations you guys have put up, I’m curious if you guys are taking too much sodium. Some of the spread sheets get 100% dv of sodium from table salt, but then also use monosodium phosphorous, which is 23% sodium by weight. Has anybody either used a different source of phosphorous, or decreased the amount of table salt and supplemented chloride somewhere else? Or am I misunderstanding something?


#2

I don’t use monosodium phosphate for exactly this reason. Instead I use a mix of: Calcium Phosphate (powder), plus a little rice bran (which gives magnesium and fiber - careful not to overdo the fiber), and there’s phosphate in the protein mix I use.


#3

If you do take too much sodium, from what I understand, it gets flushed out quite easily. I could be wrong, though.


#4

Aaaand you just alerted me to an error in my spreadsheet. Thanks @Sofor9. Chloride could be supplemented with potassium chloride, see the simple math I did.

When I get home I’m going to revisit this, see if I can work potassium chloride in better, since it’s a cheaper source of potassium.

I could be mistaken about this, but I believe I remember reading that potassium gluconate is somehow better than potassium chloride, or that the gluconic acid has some kind of side benefit, I want to say having to do with the gut flora. I believe potassium chloride is also cheaper by potassium mass, since it is a higher proportion of the molar mass than in potassium gluconate. Let me know what you learn.


#6

Well, that’s sort of true. It would be harder to overdose on sodium than magnesium or iron, but higher amounts of sodium can cause high blood pressure, retention of water weight, and I believe it either decreases absorption or accelerates loss of other ions.


#7

I’ve been doing what @chris suggested – I consider monosodium phosphate a source of sodium, and I only use as much NaCl as is necessary to get up to the sodium RDA. I use KCl as my potassium source. All in all, I’m getting 240% of the RDA of chloride, but I couldn’t find anything that indicates that this would be problematic.

Is anyone aware of any negative effects of consuming this much chloride? (No problems so far!)


#8

Oh hey, it turns out my spreadsheet didn’t have an error after all, as the nutrition label on my monosodium phosphate included sodium. So my numbers from above are accurate. If I crunch some numbers on combining potassium chloride and gluconate with as little gluconate as possible I’ll post those.
