Blueroot Health Recalls Aller-C Supplements Over Undeclared Egg, Hazelnut, and Soy Allergens

What Triggered the Aller-C Supplement Recall?

According to the announcement posted to the FDA recall database, Blueroot Health of Middletown, Connecticut initiated the voluntary action after internal quality review flagged the possibility that two lots of Vital Nutrients Aller-C may contain traces of egg, hazelnut, and soy that were not listed on the product label. Cross-contact typically occurs when shared manufacturing equipment is used for products containing allergens, and residue remains despite cleaning protocols. The company has urged consumers who are allergic or severely sensitive to any of these ingredients not to consume the affected product and to return it to the point of purchase for a full refund.

Undeclared allergens remain the leading cause of FDA food and supplement recalls in the United States. According to FDA enforcement data published annually, undeclared milk, eggs, tree nuts, soy, and wheat consistently rank among the top reasons for Class I and Class II recalls. The Food Allergen Labeling and Consumer Protection Act (FALCPA) requires that the nine major food allergens — milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame — be clearly declared on packaging, and sesame was added as the ninth major allergen under the FASTER Act that took effect in January 2023.

Why Are Undeclared Allergens Dangerous in Supplements?

The Centers for Disease Control and Prevention (CDC) and American College of Allergy, Asthma & Immunology (ACAAI) estimate that roughly 33 million Americans live with food allergies, including approximately 5.6 million children. Tree nut allergies, including hazelnut, and egg allergy are among the most common and are frequently associated with severe reactions. For a person with IgE-mediated allergy, even milligram quantities of a hidden allergen can provoke hives, airway swelling, vomiting, a drop in blood pressure, or full anaphylaxis requiring epinephrine.

Dietary supplements pose a particular labeling challenge because consumers often take them daily, sometimes assuming that "hypoallergenic" or "allergy support" branding implies the product is safe for people with allergies. Aller-C is marketed as an immune-support formula containing vitamin C and quercetin. The irony of an allergy-themed product potentially containing undeclared allergens underscores why the FDA continues to emphasize allergen control programs, supplier verification, and clear labeling under the Food Safety Modernization Act and under the Dietary Supplement Health and Education Act framework.

What Should Consumers Do If They Have the Recalled Product?

Consumers should locate the lot number printed on the bottle and compare it to the lots specified in the Blueroot Health recall notice, which is posted on the company website and on the FDA's public recall portal. If a bottle matches, the company advises discontinuing use and returning it to the point of purchase. People without a known allergy to egg, hazelnut, or soy are not considered at elevated risk, but the recall still applies.

Anyone who experienced symptoms that may be linked to the product — including itching, hives, swelling, wheezing, gastrointestinal distress, or anaphylaxis — should seek medical attention and document the event. Adverse events associated with dietary supplements can be reported directly to the FDA through the MedWatch Safety Information and Adverse Event Reporting Program, which helps regulators identify patterns that may warrant broader enforcement action. Clinicians managing patients with multiple food allergies should continue to advise rigorous label reading and awareness of recall notices, particularly for supplements and compounded products where manufacturing oversight varies.
