Prelief tablets and granulate


Key Facts: Prelief is AkPharma's brand name for calcium glycerophosphate which has a number of important uses. These fields include:

Urinary : As a palliative in interstitial cystitis, prostatitis, overactive bladder.

Intestinal : As a symptoms reducer in irritable bowel syndrome.

Prelief is taken in periodic dosages, regardless of meals or foods eaten. Clinical studies demonstrate that such use greatly reduces urinary pain and urgency in overactive bladder. Prelief is also used beneficially in terms of pain and urgency with interstitial cystitis and prostatitis. A pilot clinical study suggests beneficial use by persons with diarrhea-predominant irritable bowel syndrome (IBS) and a clinical study to confirm this is nearing completion. Clinical studies are also underway to confirm cellular effects in interstitial cystitis.

Safety Information: Prelief is made from an FDA Generally Recognized as Safe (GRAS) 1 mineral and is also listed in the Food Chemicals Codex (FCC). 2



Prelief Tablets : Each tablet contains 345 mg calcium glycerophosphate (65 mg of elemental calcium). The tablets also contain 0.25% magnesium stearate as a processing aid. Two tablets are equivalent to 690 mg calcium glycerophosphate (130mg of elemental calcium).

Prelief Powder : Each ¼ teaspoon usage of powder is comparable to two tablets. The powder dissolves rapidly in food or non-alcoholic beverages. Tablets are recommended for taking with alcoholic beverages.

Two tablets or about ¼ teaspoon of powder provides 15% (130 mg) of the FDA Recommended Daily Intake (RDI) for calcium and 10% (100 mg) of the FDA RDI for phosphorus. No sodium; no aluminum; no sugar; no potassium.

Reasons for Use: Prelief is used as an intervention in certain identifiable urinary and intestinal problems such as interstitial cystitis, prostatitis, overactive bladder and irritable bowel syndrome.

Action: Through a mechanism not fully elucidated, Prelief appears to reduce cellular inflammation in the urinary bladder. It also appears to non-irritatively encourage cellular reproduction. This is possibly a result of Prelief's uniquely free calcium ion and/or the glycerophosphate moiety, working singly or together. In addition, Prelief neutralizes the acid found in a large number of foods which many people find cause them discomfort.

Powder: ¼ teaspoon of powder 2 times a day. More can be used when needed.

Kosher: Prelief is Kosher and Parve.
