Along with pottassium get calcium and magnesium.

Also tak ea good multivatamin that doesn't contain sugar or starches. I like Twin Labs one a day. You can get them with or without iron. Ifyou eat alot of red meat, you probably want the iron free. I don't get enough iron in diet, so I use the ones with iron. Be careful of the one a day weight smart, those so have sugar.

Read through the suppliment forum on this board for other suggestions so you can taylor a suppliment plan for what you need.

I regularly take suppliments. I had blood work odne a few months ago and all my blood levels were fine for potassium, calcium and so on.

If you have any preexisting heart, kidney, or other issues, be careful about suppliments though and get medical advice.
