Anedote. I became a vegetarian and started 10,000 unit daily vitamin D supplementation this winter. I've also experienced cold after cold. My nose is a river. Body aches, fevers. So has my family, and our friends' families. So by the logic of the other children of the parent I should quit my vitamin D supplementation, and probably avoid friends that take Vitamin D. ;-)
