Alpha-gal Syndrome: What to Avoid When Choosing Common Household Items

What is Alpha-Gal Syndrome

Alpha-gal syndrome (AGS), is a condition where individuals may experience serious, potentially life-threatening allergic reactions to alpha-gal sugar (galactose-α-1,3-galactose), which is found in most mammals (pork, cattle, rabbit, lamb, etc.). With many products containing animal-derived ingredients, individuals with AGS are at risk of experiencing allergic reactions after not only eating food but also coming into contact with common personal care and household items.

Lone Star Tick

How Is Alpha-gal Syndrome Acquired

The Lone Star tick, native to the eastern United States and Mexico, transmits alpha-gal molecules to humans through its saliva. After being bitten, people begin to create antibodies to alpha-gal sugar, causing signs and symptoms of AGS when exposed to it. The best methods to not be bitten by the Lone Star tick are to wear cover-up garments treated with permethrin, spray shoes with permethrin, and avoid high-exposure areas such as woodlands and bushy tall grasses.

Signs and Symptoms of Alpha-Gal Syndrome

According to the Centers for Disease Control and Prevention, signs and symptoms of AGS may be:

  • hives, itching, scaly skin

  • swelling of the lips, face, tongue and throat

  • respiratory problems such as wheezing or shortness of breath

  • GI effects such as stomach pain, diarrhea, upset stomach, nausea, and vomiting

  • hypotension

Common Animal-Derived Ingredients & Household Products

To know which products will trigger an AGS response, it is important to be able to identify ingredients to avoid or be careful of. Below is a list of ingredients commonly found in household products that may be animal-derived and their use. It is important to note, that although carrageenan is derived from red seaweed and is not animal-derived, it does contain alpha-gal and may cause individuals with AGS to have an allergic reaction.

Because animal-derived ingredients can be found in many unassuming household products, it's difficult for those with alpha-gal syndrome (AGS) to avoid products that may cause a serious and potentially life-threatening allergic reaction. To better assist those within the AGS and animal-free community, the VeganMed team, Two Alpha Gals, and Alpha-gal Information have reviewed common household products for the presence of animal-derived ingredients and listed a few verified animal-free options to choose from with peace of mind.


As a reminder, please comment on this FDA Citizen Petition, requesting clear labeling of animal-derived ingredients in medications. Together, we can make a difference.
