Halal is Arabic for permissible. Halal food is that which adheres to Islamic law, as defined in the Koran. This means that food has been subjected to approved certification systems which guarantee to consumers that nothing in the food has any forbidden components. Halal certificates are issued, for a fee, by a certifying body.
Solgar chose the Halal Food Authority (HFA), a U.K. based organisation that adheres to the strictest laws of Halal, to certify their products.
