The Claim
Chronic high-dose vitamin C supplementation in a 42-year-old male with no prior renal disease was associated with the development of severe acute kidney injury characterized by oxalate crystal deposition in renal tissue, with resolution following discontinuation of supplementation and conservative management.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Chronic use of high-dose vitamin C supplements in a 42-year-old man without prior kidney disease led to severe acute kidney injury with oxalate crystals in the kidneys, and the condition improved after stopping the supplements and receiving standard medical care.

High-dose chronic vitamin C supplementation in a 42-year-old male with no prior renal disease was associated with the development of severe acute kidney injury characterized by oxalate crystal deposition in renal tissue, which resolved after discontinuation of supplementation and conservative management.
When a person takes large amounts of vitamin C for a long time, the body breaks it down into oxalic acid. The kidneys filter this acid out, but too much of it causes crystals to form inside the kidney tubes. These crystals cut and block the tubes, making the kidneys stop working properly. When the person stops taking vitamin C, the body clears the crystals and the kidneys recover.
What the research says
1 studyStudy: VITAMIN C INDUCED OXALATE NEPHROPATHY : A RARE CASE REPORT
A man took a lot of vitamin C pills for two years and got sick kidneys filled with crystals, but when he stopped taking them, his kidneys got better. This shows too much vitamin C can hurt kidneys — and stopping helps.
