About Effer-K®

Effer-K® is an effervescent liquid potassium supplement in tablet form. Simply drop the tablet into a glass of water, one minute for the tablet to dissolve, then enjoy the great tasting non-carbonated beverage.

Effer-K® is the combination of potassium bicarbonate and citric acid as an effervescent tablet. When placed in water, or other aqueous liquids, the citric acid and potassium bicarbonate react. The effervescent reaction provides potassium as potassium citrate in a slightly acidic solution. The initial bicarbonate molecule is bubbled off as carbon dioxide and water. Potassium citrate and water remain. Potassium citrate is the type of potassium found naturally in fruit, which is why Effer-K® tastes great!

Effer-K® is now available in 20mEq and 10mEq doses:

Effer-K® 20 mEq, Unflavored
Effer-K® 20 mEq, Orange Cream
Effer-K® 10 mEq, Unflavored
Effer-K® 10 mEq, Cherry Vanilla

Most physicians prescribe potassium in tablet form in these doses. Effer-K® can be taken instead of a solid potassium tablet.
