there is no universally applicable answer to whether all of ALLEN's products are halal, as the company may offer a diverse range of products, and their halal status can vary depending on ingredients and manufacturing processes.
If you are concerned about the halal status of a particular product from ALLEN or any other company, it's best to check the product's packaging or labeling for any halal certification or contact the company's customer support directly to inquire about the specific product's halal status. Companies often provide information about the halal certification status of their products, especially if it is relevant to their target market.
