title: Role of vitamins in urolithiasis.
abstract: The serum vitamin A level of the lithiasis patients was found to be low, although vitamin A intake was not different from control subjects. Vitamin C level in blood was not significantly different in the patients as compared with control subjects. The control subjects and urolithiasis patients were also subjected to the oral supplementation of L-tryptophan and glycine. It was observed that neither oxalate nor xanthurenic acid increased in urine after loading. It was concluded that vitamin B6 deficiency does not exist in these cases.
