oxalates and fat absorption
Taking calcium carbonate supplements with meals reduces oxaluria, whereas taking them at bedtime increases calciuria and has no effect on oxaluria.3 The preferred calcium supplement for people at risk of stone formation is calcium citrate because it helps to increase urinary citrate excretion. We recommend a dose of 200–400 mg if dietary calcium cannot be increased. the use of vitamin C supplements may increase oxaluria and be associated with an increased risk of stone formation. The ingestion of animal protein has adverse affects on urine chemistries: it lowers citrate excretion and increases calcium and uric acid excretion https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1455427/ Previous studies revealed that calcium oxalate (CaOx) or calcium phosphate (CaP) with carbonate-apatite and hydroxyapatite is the major component of prostate calculi [3], which are usually discovered in men with acute or chronic prostatitis and can cause chronic prostatitis [8 https://www.ncbi.nlm.nih.gov/pmc/ar
