I started experimenting with sodium intake a few weeks back. My hematocrit did decrease 2 points during that time. I did a blood test before and after sodium intake.
I consume a little extra salt 3 to 4 times per day. Each time I also take a potassium tablet. I’ve heard that you should consume salt with potassium. I also take in a little magnesium.
It is said sodium intake makes you a little more vascular, more blood volume and will help preserve muscle when on a low carb diet, which is what I am doing. I can’t say it made be feel like a million bucks cuz I usually feel like that anyway when eating and sleeping right.
On a side note, few years back when I went to the hospital they did bloodwork before administering IV fluids. My Hematocrit was 47. Twenty-four hours after IV it was 44. Main ingredients in IV are sodium and potassium. Also gained 10 lbs from it.
