My son has ASD and I was lucky enough to stumble across the horrible effects it had on him over a year ago. His symptoms are irritability and total sleeplessness ... he stays awake all night after having some! I truly believe this is a harmful substance and should be banned. It's confusing because it's a 'natural colour'. I could see a lot of people not knowing that this additive could cause such a huge side effect! – Jenny
