Potassium is available in a variety of forms such as potassium chloride, potassium bicarbonate, potassium citrate, potassium gluconate and potassium acetate. There are different forms because potassium is available as capsules, tablets, effervescent tablets, liquids and powder. Getting the right amount of potassium is important. Ask your physician if you need potassium supplements and if so, how much your body needs.
Dosage
Most Americans get enough potassium from diet alone, but it may be necessary for some individuals to take a potassium supplement to prevent or treat a potassium deficiency. The recommended dose for healthy adults, according to Drugs.com, ranges from 40 to 100 mEq per day to replace potassium lost by your body. To prevent potassium loss, your body won't require as much as it would to replace lost potassium; you only need 16 to 24 mEq per day. The dosage should not be taken at one time, as your body can only absorb so much potassium at one time. The dose should be split into two or three smaller doses throughout the day; allowing your body to absorb small amounts over a period of time.
Prevention vs. Loss
Preventing a potassium loss can help keep you from developing a deficiency. Potassium is very important for smooth muscle and skeletal contraction and regulating other minerals within your body. Preventing the loss of potassium will help keep your potassium levels normal. A potassium loss means that your potassium levels are no longer within the normal range and have dropped. Depending upon the severity of the loss, you could develop a deficiency.
How Potassium is Lost
Potassium is found in plenty of fruits and vegetables so most people don't have to worry about developing a potassium deficiency. You can lose potassium through excessive sweating, vomiting and diarrhea. You may also have difficulty absorbing potassium if you suffer from malnutrition or have malabsorption syndromes. Certain medications, such as some heart medications and diuretics, can also deplete your potassium or make it difficult to absorb potassium.
Sources
It's better to receive nutrition from food rather than a supplement. The most abundant source of potassium, according to MayoClinic.com, is cooked acorn squash; it delivers 896 mg of potassium, or 23 mEq. Beans, yogurt, raisins, milk and fruits such as watermelon, cantaloupe and bananas also provide a good amount of potassium.
