I've just checked the LT bag (all the info on how & when to take the shakes and also the full list of the ingredients) and there is no mention of eggs. Just soya and lactose and a bunch of other stuff!!
Was quite surprised to see citric acid in the flapjacks though as I thought we weren't allowed that. Not really looked at the ingredients on the flapjacks as there is not a chance I'll have them!! I would have beleived if they were made from composte and straw!!
