Glu-K

For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods.

The following table includes some potassium-rich foods.

The daily amount of potassium needed is defined in several different ways.

For U.S.—
• Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy).
• Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).

For Canada—
• Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.

Because lack of potassium is rare, there is no RDA or RNI for this mineral. However, it is thought that 1600 to 2000 mg (40 to 50 milliequivalents [mEq]) per day for adults is adequate.

Remember:

• The total amount of potassium that you get every day includes what you get from food and what you may take as a supplement. Read the labels of processed foods. Many foods now have added potassium.
• Your total intake of potassium should not be greater than the recommended amounts, unless ordered by your doctor. In some cases, too much potassium may cause muscle weakness, confusion, irregular heartbeat, or difficult breathing.

If you are taking a dietary supplement without a prescription, carefully read and follow any precautions on the label. For these supplements, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Although there is no specific information comparing use of potassium supplements in children with use in other age groups, they are not expected to cause different side effects or problems in children than they do in adults.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of potassium supplements in the elderly with use in other age groups, they are not expected to cause different side effects or problems in older people than they do in younger adults.

Older adults may be at a greater risk of developing high blood levels of potassium (hyperkalemia).

Pregnancy

Potassium supplements have not been shown to cause problems in humans.

Breast Feeding

Potassium supplements pass into breast milk. However, this medicine has not been reported to cause problems in nursing babies.

Interactions with Medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking any of these dietary supplements, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Other Medical Problems

The presence of other medical problems may affect the use of dietary supplements in this class. Make sure you tell your doctor if you have any other medical problems, especially:

• Addison's disease (underactive adrenal glands) or
• Dehydration (excessive loss of body water, continuing or severe)
• Type 2 diabetes mellitus or
• Kidney disease—Potassium supplements may increase the risk of hyperkalemia (high blood levels of potassium), which may worsen or cause heart problems in patients with these conditions.
