Another Problem for Members of the Church of Herbs and Supplements

A study of women who were followed over an 8-year period has found that vitamin C supplementation, particularly in high dose and long duration, may increase the risk of age-related cataracts. The study included 24,593 women aged 49-83 years from the Swedish Mammography Cohort (follow-up from September 1997 to October 2005). The researchers used a self-administered questionnaire to collect information on dietary supplement use and lifestyle factors. (from Quackwatch)

The study controlled for hormone replacement thereapy, so it wasn't that, sports fans.  They also compared steroid users, and multi-vit users (containing C) to the high dose C group, and eliminated those as contributory factors. 

Don't get me wrong.  Vitamin C may do some good things with intermittent high use.  I've had "some" patients who were prone to bladder infections that "may" have benefited from taking C (along with the antibiotic, not without it).  It's hard to quantify and I didn't do a controlled study.  Vitamin C acidifies the urine, which germs don't cotton to.
