Great. I take Vitamin C supplement and have had three MRIs done in the past two years.
have you had contrast used with the MRI in any of the three? That is the key, gadolinium contrast (the only type used with MRI). The oxalate pulls the contents out of the contrast.
I’ve been trying to tell people for a while that vitamin C supplements (most are junk) are linked to stone formation, not vitamin D supplements or calcium supplements per se.
Mayo has 24 hour urine test for this . It is expensive. You will need to have symptoms to get insurance to pay.
