Interaction with Herbs
Folic
acid
People receiving dialysis for kidney failure often have low blood levels of folic acid.
However, folic acid blood levels should return to normal following kidney transplant. A
preliminary study of people taking azathioprine to prevent organ rejection revealed that blood
levels of folic acid remained well below those of individuals not taking the drug. The highest
blood folic acid level was observed in an individual who had not taken azathioprine for two
years.1 Controlled studies are needed to determine whether people taking
azathioprine should supplement with folic acid.
