TheraLith XR provides 12 mEq of citrate alkali in four daily tablets. The nutrients in TheraLith XR help increase urinary citrate levels and decrease urinary oxalate levels, which are key factors to reduce the risk of calcium oxalate crystallization.* However, TheraLith XR is not formulated to change the pH of urine.

CitraLith provides 30 mEq of citrate alkali in two single-serving powder packets per day. The nutrients in CitraLith also help increase urinary citrate levels and decrease urinary oxalate levels to reduce the risk of calcium oxalate crystallization. But, the additional citrate alkali helps promote an optimal urine pH, which also helps reduce the risk of uric acid crystallization.*

Independently tested and certified. TheraLith XR is tested and certified by NSF® International for content accuracy and purity, so you know exactly what you’re getting.

The list below includes some of the more common potential interactions. This is not meant to be a comprehensive list or take the place of advice from your healthcare provider. As with any dietary supplement, discuss with your pharmacist and/or healthcare team to determine whether TheraLith XR can be taken along with your medications.

Antibiotics: Taking magnesium with antibiotics can decrease their absorption and effectiveness. Depending on which antibiotic is prescribed, you may need to separate TheraLith XR from the antibiotic, as indicated below.  

Tetracycline antibiotics (doxycycline, minocycline, demeclocycline): Separate by 4 hours.   

Quinolone antibiotics (Ciprofloxacin (Cipro), gemifloxacin (Factive), levofloxacin (Levaquin), Moxifloxacin (Avelox)): Separate by 6 hours.

Levodopa: Vitamin B₆ may reduce the effects of levodopa when taken alone, but not when taken in conjunction with carbidopa. Do not take TheraLith XR along with levodopa unless you are also taking carbidopa.  

Potassium-sparing diuretics (spironolactone, eplerenone, triamterene): These medications can increase potassium and/or magnesium levels. Taking TheraLith XR, which contains potassium and magnesium, along with these medications, may cause too much potassium and/or magnesium in the body.    

High blood pressure medications (ACE inhibitors: captopril, lisinopril, cilazapril, enalapril, fosinopril, etc. or Angiotensin Receptor Blockers: losartan, valsartan, azilsartan, candesartan, telmisartan, etc.): These medications can increase potassium levels. Taking TheraLith XR, which contains potassium, along with these medications may cause too much potassium in the body.    

Bisphosphonates (i.e., alendronate (Fosamax), etidronate (Didronel), risedronate (Actonel), ibandronate (Boniva), tiludronate (Skelid)): Magnesium can decrease the absorption of these medications. Separate by 2 hours.
