Answer:

Although most Americans get enough potassium from their diets and many common foods are rich in potassium, there is evidence that many Americans may not be getting adequate potassium, which, for most adults is 4,700 mg per day.

Many potassium supplements provide just a small fraction of this amount, often 99 mg of potassium per daily serving. The reasons for this are explained in the "What to Consider When Buying" section of the Potassium Supplements Review. However, as also noted in the Review, supplements providing larger doses of potassium are now available on the market. These may be more practical for people who take larger doses of potassium for a specific reason, such as lowering high blood pressure, or for those who are unable to get enough potassium in their diet.

Coconut water is high in potassium. One of the highest ways of getting it naturally.
A very low sugardrink (1tsp from the coconut) but make sure you purchase only 100% coconut water not from concentrate or with preservatives etc in. A very pleasant drink when chilled. However don't overdue a good thing as too much of this could cause an imbalance of potassium and salt as it can cause you to get too high in potassium, 2 or 3 glasses a day should be fine.

Hi Wendy - You're correct that coconut water can contain substantial amounts of potassium. Please see our tests of products in the Coconut Water Review: https://www.consumerlab.com/reviews/_/coconut-water/, which includes amounts of potassium. sodium, magnesium and sugars found in each. Also, beware that people taking certain medications, or with certain conditions should be cautious: https://www.consumerlab.com/reviews/_/coconut-water/#cautions

Many salt substitutes are made from potassium chloride. I take 1/8 tsp of salt substitute in water once daily to keep my potassium up.
