Vitamin D helps fight E. coli
Reduce the risk of UTIs caused by E. coli
Postmenopausal women are more likely to have urinary tract infection and low levels of vitamin D. To test the effect of vitamin D on immune activity, researchers took healthy bladder tissue samples from eight postmenopausal women before and after the women took 2,000 IU of vitamin D per day for 12 weeks.
By the end of the study, vitamin D levels had increased 70 percent and, when researchers exposed bladder cells to E. coli bacteria, immune activity tripled.
Researchers concluded vitamin D prepares bladder tissue to fight E. coli infection by increasing the antimicrobial immune response.
