Isagenix is a food supplement used for dieting.   My wife contacted the firm through a nurse who works at the QMC and told her that she was Type 1 and the nurse said that there was no danger.   The first time she took the supplement she had an instant reaction and we later found that it contains Kiwi fruit amongst other things that she is allergic to.
 
The firm at first denied that there was anything in it that could cause a reaction but later admitted that it contained Kiwi.
 
The full course cost £200 and they will only offer a part refund.
 
Avoid this at all costs.
