Professor Hayes' vitamin D research featured

Dr. Hayes has studied nutrition and the immune system for more than 25 years, and vitamin D and MS for almost 20 years. She has many friends with MS. Dr. Hayes is a recipient of numerous National Multiple Sclerosis Society grants, and was notified in October that she would receive another award to continue her vitamin D studies.

"There is very good scientific evidence correlating low levels of vitamin D with a high risk of MS and with high disability in people with MS," said Colleen Hayes, PhD, a professor and researcher at the University of Wisconsin-Madison.
