Question:
Can vitamin C from a supplement cause blood in the urine and painful urination?

Answer:
The pain and blood in her urine could have been caused by vitamin C itself rather than by a contaminant. See the Concerns and Cautions section of the Vitamin C Supplements Review for a full explanation >>.

I was asked by a US Navy hospital corpsman decades ago if I took a Vitamin C supplement after examining a urine sample under a microscope. When I told him I did, he warned me to be careful how much supplementary Vitamin C I took. He said it could crystallize in the urine, leading to urinary tract injury and even result in kidney stones. I quit taking it immediately.
