Hello Jesusfiliu, thank you for your inquiry. Under Swiss law, the origin of ingredients must be indicated if they make up 50% or more of the product (for ingredients of animal origin, this threshold is only 20%), and only if the packaging is misleading—for example, if it suggests a different origin. We comply with these regulations as well as the safety standards for our products. If you cannot find any indication on a product, it means that we consider the origin of the ingredients to be internal information that we do not disclose. Best regards, your M-Infoline team
