The 10 Best Potassium Supplements

One of the many nondescript minerals that are present in our body is potassium. It gives no provisions of robust energy or toned muscles. There are no claimants of its benefits as a weight control supplement. Yet, the human body cannot function without it.

This mineral is needed for the daily tasks of the organs. It works in every cellular organism of the body. However, its quantities have to be optimum. A quantum increase in the level of potassium in the body can lead to serious medical conditions over a period of time.

For this reason, the FDA has permitted only 100mg of potassium that can be purchased over the counter. This is less than 2% of the total daily intake of 4700mg. Most potassium supplements serve only 99mg and for good reasons.

They are made from GMO-free ingredients with a minimum addition of other minerals. It is recommended for healthy adults, those without any underlying medical conditions and who are not pregnant or nursing.

A doctor’s consultation is always necessary. The user should never exceed the recommended dose without consulting his or her doctor. The best natural dietary foods that are rich in potassium are spinach, prunes, tomatoes, potatoes, citrus fruits, and bananas.

The Dosage And Side Effects of Potassium Supplements

Scientific research has advised the following dosage according to the age and medical condition of the user. However, a consultation with your doctor is necessary before use. For an adult an oral supplementation of 4.7 gams a day is normal. A person suffering from low potassium in their body would take about 1560 to 3900 mg of elemental potassium on a daily basis. The dosage would be divided between 2 to 5 times a day.

The recommendation of potassium for a person suffering from hypertension would be 3500 to 5000 mg a day. Patients who had a stroke would be given 3.5 grams of elemental potassium to be taken every day. Infants are given only 0.4 grams a day until they are about 6 months old. 0.7 grams/day for ages between 6 to 12 months and 3 grams for ages between 1 to 3 years. 3.8 grams are for children between 4 to 8 years of age and 4.5 grams for children who are between the ages of 9 to 13 years old.

High levels of potassium can result in burning or tingling sensations leading to weakness. If left untreated for a long time it may cause mental confusion, low blood pressure, irregular heart rhythm or death.  If you are allergic to aspirin or tartrazine avoid supplements that have tartrazine.

If you are taking dialysis the potassium in your blood will vary depending on the type of dialysis. Supplementation may be required and should be supervised by a health care professional. If you are suffering from any digestive disorders abstain from using any supplemental forms of potassium. If you have had a kidney transplant any supplementation should be under the guidance of your doctor.

Frequently Asked Questions (FAQs)

How To Prevent Consuming Too Much Potassium, If I Am On A Low Potassium Diet?

Try and avoid foods that contain high potassium. Note your food intake and collaborate with your physician for a guideline. A process called leaching removes some potassium from vegetables. Corn, beets, sweet potatoes should be peeled and rinsed in warm water and then cooked with 5 times more water than you would normally use. A ratio of 10:1 for water to vegetables is to be used for this process.

How Long Does It Take For The Supplements To Work?

Mild hypokalemia (condition of low potassium) the levels will become normal in a few days. If symptoms are present you would need a few days of treatment for them to go away.

Is There Too Much Potassium In Black Coffee?

One cup of black coffee has 116 milligrams of potassium. Potassium levels can rise with 3 to 4 cups of drinking coffee in a day. Adding cream or milk only raises the quantity of potassium in the body. It is safe to limit coffee intake to only two cups in a day.

The Final Note

Potassium levels should be maintained by consuming a balanced diet. Supplementation should be taken only after consulting a doctor. A check on the number of caffeinated drinks is essential. The diuretic action of caffeine in caffeinated beverages is one of the reasons that can cause hypokalemia.

Although potassium supplements are quite helpful in helping meet our daily requirements of potassium, make sure to follow a balanced diet plan as well. Cabbage, radish, mushroom, raw onion, grapes, pineapple, blueberries, eggplant, lettuce leaves, cucumber, cauliflower, and green beans are some potassium-rich foods you can include in your diet.
