Can too much b12 affect your kidneys?
Just so, does b12 affect kidney function?
B12 deficiency is associated with anemia and neurological disorders. However, in CKD homocysteine levels increase as GFR declines, independent of B12 levels [8]. Thus, there is a complex relationship between the processing of B12 and albumin in the gut and the kidney.
Also asked, what vitamins can be hard on the kidneys?
The fat soluble vitamins (A, D, E and K) are more likely to build up in your body, so these are avoided unless prescribed by your kidney doctor. Vitamin A is especially a concern, as toxic levels may occur with daily supplements. Vitamin C supplements are recommended in a 60 to 100 mg dose.
However, there are reports of certain supplements causing kidney problems. A 2012 review of supplement-induced kidney dysfunction lists 15 herbs and supplements reported to have caused kidney problems, including chromium, creatine, licorice, willow bark, vitamin C and yohimbe (Gabardi, Clin J Am Soc Nephrol 2012).
