I asked Becky about this and her statement was that at times her sense of smell was impaired. She hadn't figured out the conditions that preceded those occasions when it was. However, she shared information she had gleaned from Herb Mendell's Vitamin and Herb Bible (I think I have the name correct, at least Herb Mendell is correct). It is that, accoding to this book, Vitamin A and Zinc both contribute to restoring one's sense of smell. Zinc is pretty cool and does lots for us. The book also explains that chelated (formulated for easy digestion) is the preferred form of zinc. Jeff, part time CG for Becky [log in to unmask],net
