@seamyb - low-sodium V8 (or generic equivalent) has a lot of potassium - 900 mg per 8 oz. glass, 500 mg. or so for regular V8. This has helped a lot of people who wanted a quick dose of potassium and fewer calories than sweet potatoes, which I love!
btw, I'm not scared of potassium supplementation - when I first tried methylfolate 10 years ago, it gave me a noticeable boost in energy after 1 or 2 days, followed the next day by severe fatigue due to potassium tanking (which I'd learned by reading several posts by member Freddd here about low potassium and methylation).
I was very leery at first, but titrated up using a potassium supplement over a couple of days, in divided doses (spread throughout the day) started with 400 mg. I think and over 2 or 3 days worked up to 1000 mg a day (200 or 300 mg with each meal) and I still need that much. I also take 200 mg middle of the night because for some reason my potassium tends to drop during the night and I would often wake up with cramps in my feet or legs or feet before I started the potassium supplementation.
The RDA for potassium is 4700, so the 1000 - 1200 mg I take is 25% of the RDA. Also, I found that I tolerated potassium gluconate the best. Many do well with potassium citrate, but it contributed to or exacerbated a UTI infection for me.
