The first thing you should know is that you will rarely if ever, have a problem with potassium if you get it from fresh food—even at 10 cups of vegetables per day. 

However, there are a few exceptions, including if you:
• Have stage 5 kidney disease
• Take an ace inhibitor
• Take a beta-blocker
• Use potassium-sparing diabetics
• Have Addison’s disease
• Have hyperkalemia

Now let’s talk about extreme doses of potassium. When you have between 8,000 and 10,000 mg of potassium, you may begin to feel nauseous. If you are already low on potassium and you take something like 14,000 mg of potassium, this could be very dangerous.

Keep in mind that potassium doesn’t store in the body. If you do prolonged fasting, you can deplete your potassium quickly. To prevent this, I recommend electrolyte fasting, which is including electrolytes in your fast. 
If you already are deficient in potassium, vitamin B1 can exaggerate the symptoms. 
I also recommend that you keep your sodium and potassium levels balanced. If you consume a lot of potassium without any sodium, that’s going to be a problem. The same problem happens if you have a lot of sodium and no potassium. You need four times as much potassium as sodium, so make your you have sodium and potassium in a 1 to 4 ratio.

In summary, the average healthy person would have to take a tremendous amount of potassium to develop a problem of high potassium levels in the blood. If you have 1,000-4,000 mg of potassium a day, you’re not going to have a problem.
