[Update - Oops! I typed in the wrong amount of sodium in my electrolyte mix. Correct amount is much higher, see later post on this thread] I was looking through a bunch of different research studies and found the following recommendation for patients with low blood volume (hypovolemic patients) in a review of POTS - http://onlinelibrary.wiley.com/doi/10.1111/j.1540-8167.2008.01407.x/pdf : Wow, that's a lot of sodium! I thought I was taking a reasonable amount but it's nowhere near this. I looked it up and 1 gram salt has 387.6 mg sodium. So that means (please check my math!) that 10 grams of salt = 3876 mg sodium or 168.52 mEq sodium. (Note: I used http://www.nafwa.org/convert1.php to convert the units from mg to mEq). That's on the low end of the recommendation. Double everything to get the high end of 20 grams of salt. I know I don't get this much. My guess is that I get maybe 2000 mg of sodium daily (maybe more?). This guess comes from adding up salt tablets (180 mg x 5 tablets = 900 mg), a liter of electrolyte solution (my home made version has about 450 mg sodium) and whatever is in my diet. I think my diet is fairly low in sodium because I don't eat a lot of fast/processed food other than some canned beans. Does anyone out there take 10-20 grams of salt? Comments? I'm just curious whether I should try increasing my sodium a bit more.
