Re: Caffeine and potassium levels?
No, caffeine does not deplete potassium levels.
Your body normally regulates potassium within a very narrow normal limit (around 3.5-5.0mg/dl, depending on the lab), as one of potassium's very important job, is regulating the heart beat.
Some medications can cause a low potassium, such as diuretics for high blood pressure (hydrochlorathaizide).
Some medical conditions can also change the potassium level. - If you have kidney disease, your potassium can actually go too high.
Hope this helps.
