I have just written a complaint to the seller. If a product contains E129 and carries a warning that it may cause 'an adverse effect on activity and attention in children' this needs to be stated on the product details. I'm not complaining about the product, but the lack of information provided for the buyer. E129 is a colouring widely used in the USA but widely banned in Europe. Candy or sweets usually contain pretty grisly ingredients, but if the Americans are putting a warning on, it must be one to avoid.
