Clinical Need

• Over 25% of Americans experience allergies each year, with symptoms often exacerbated by seasonal changes that increase exposure to allergens.
• Seasonal and environmental factors can trigger histamine responses that lead to respiratory discomfort, sinus pressure, and elevated histamine levels, impacting daily comfort and well-being.
• Many patients seek natural, nondrowsy solutions to maintain normal respiratory and sinus function without the side effects commonly associated with conventional allergy medications.

Science

• Mast cells play a central role in the body’s response to allergens by releasing histamine, which helps fight foreign particles. However, overactive mast cell responses can lead to excessive histamine release, resulting in respiratory discomfort, sinus congestion, and other allergy-like symptoms.
• Oxidative stress can intensify symptoms by generating free radicals that damage cells and amplify inflammatory pathways, potentially worsening respiratory discomfort, sinus pressure, and immune reactivity, creating a cycle that prolongs and intensifies symptoms.
• When the immune system reacts appropriately to allergens without becoming overactive, it promotes overall respiratory and sinus health, reducing susceptibility to discomfort associated with seasonal changes.

Solution 

• Aller-C® is a unique, comprehensive approach to respiratory health, combining carefully selected nutrients to support balanced histamine levels, immune resilience, and sinus comfort, addressing the root causes of seasonal and environmental discomfort
• Featuring isoquercitrin, a clinically studied nutraceutical offering the benefits of quercetin with superior absorption and bioavailability, to help promote cellular antioxidant defenses and a normal histamine response
• Nondrowsy formula
