Love this article on the importance of adequate Vitamin C for brain function. This is just another in a list of many reasons to supplement Vitamin C. I often prescribe it to “bowel tolerance” or a maximum of 10,000 mg daily in divided doses. I know others who prescribe even higher doses via IV therapies. A minimal dose in my opinion is 1,000 mg Vitamin C twice daily. AND eat those Vitamin C-rich foods, too!!
