How does PreHistin® work?

Elevated IgE levels have been shown to be associated with an overly active release of histamine which has been linked to annoying symptoms such as runny nose, sneezing, itchy eyes and throat, and nasal congestion. PreHistin® works by maintaining healthy IgE antibody levels in your body, which helps regulate normal histamine release. By regulating histamine release, your body may not overreact to foreign substances like pollen, mold, airborn allergens, mountain cedar, grass allergens, or animal dander.
