Doctor-formulated, Allerfin® is a unique proprietary blend of the world’s most researched natural ingredients for helping you feel your best, whatever the season. Unlike other products, which offer only partial relief, Allerfin is a holistic formula that targets three areas of the body: the sinuses, lungs, and eyes.*

  • Sinus Support*: This formula includes three ingredients shown in human clinical research to support the health of the nasal passageways*: Allerinol™ —  a proprietary extract of the Japanese herb Perilla frutescens; Bromelain —  an enzyme derived from pineapple; and Nettles —  an herb used in traditional European herbalism.
  • Lung Support*: Double-blind, placebo-controlled trials have shown that bromelain supports free and easy breathing.* This effect is likely due to bromelain’s documented ability to support the health of the bronchial passageways.*
  • Eye Support*: Double-blind, placebo-controlled trials have found that both Allerinol and quercetin support the health and comfort of the eyes in human subjects.*
