What are the different ways I can take a potassium supplement?

Dr. Michael Roizen, MD

There are about as many ways to take a potassium supplement as there are ways to skin a cat. Only kidding! We’re pet lovers. If you’re in the market for a potassium supplement, you have a number of choices. Your doctor will help you figure out which one is best for you, but your options include:
  • a liquid that you take by mouth
  • regular tablets that you take by mouth
  • long-acting, extended-release tablets
  • long-acting capsules that may be a bit easier to swallow
  • powder or granules that get dissolved in a liquid like water or juice
  • effervescent tablets which dissolve in a glass of water or juice.
 Regardless of which form of potassium you take, you should take it with a full glass of water (the colder the better as this will help make the potassium taste, well, better) or juice. DON’T TAKE A POTASSIUM SUPPLEMENT WITHOUT YOUR DOC’S OKAY and have kidney function tests beforehand. Follow your doc’s directions about how many times a day to take your potassium, whether you should take it with food, and anything else you should know about taking the supplement.

Potassium supplements are available as liquids, powders and granules to mix with fluids, tablets, extended-release tablets and extended-release capsules. Take your supplement with a full glass of water or fruit juice, usually about one to four times a day either with food or right after a meal. Talk to your doctor or pharmacist about which form of potassium best meets your needs.
