SniZtop® proprietary formula is made of natural & unique bioactives derived from quail eggs. SniZtop® acts upstream of the allergic cascade by blocking allergens before they can activate the immune cells and therefore prevents the release of inflammatory mediators such as histamine. The efficacy of SniZtop® is supported by a randomized, double-blind, crossover & placebo-controlled study. SniZtop® relieves the most bothersome symptoms within 5 to 10 minutes, such as rhinorrhea, itchy eyes, etc. SniZtop® is adapted to the whole family.
