I had quit taking potassium supplements because so many posts I read made me feel like I would die if I took even a little too much.
Several days ago when I first started getting at least 4 g of salt every day to deal with orthostatic hypotension, I quit supplementing with potassium.
I hadn’t been sleeping well up til then, but slept really well right from the first day of adequate sodium, then in the past couple of days, started not being able to sleep. Last night was the worst and my calf and feet muscles felt like wood.
I gave in when I couldn’t sleep and took 891 mg of potassium. After about 45 mins, my legs felt better and I slept soundly through the rest of the night.
This morning I researched potassium and found that the recommended daily intake is 4.7 g and there is no established upper limit, although 1 study said that more than 13 g per day was probably not a good idea.
Also, the sodium:potassium ratio is listed as 1:2 or 1:3 but that’s based on a recommendation of no more than 2.5 g of salt per day, so I have no idea what the real ratio should be.
