Product Comparison

So, how does PreHistin® stack up against the competition?

PreHistin® is the “World’s First Pre-Histamine.” Most popular allergy relief products on the market, like Claritin®, Zyrtec®, Allegra®, and Benadryl® are “anti-histamine” drugs, which means they attack the histamines after they are released, but often leave you feeling drowsy for hours. PreHistin® is a “pre-histamine” which means it regulates the release of histamine.

PreHistin® is a unique proprietary nutritional supplement available without a prescription, aimed specifically at rectifying imbalances in the immune system that trigger the over-production of allergy symptom-causing substances including histamines.

Anti-histamines act to block the effects of histamine only AFTER histamine has already been released. Anti-histamines often result in uncomfortable and irritating side effects, such as drowsiness or sedation, headache, dry mouth, constipation, dizziness and disturbed sleep. PreHistin® has none of these side effects.
