Hi
I don't have a Testimonial for your problem, but I am a firm believer in the benefits to your immune system by taking them.
The best value at the moment is Glyco Balance, a Glyconutrient powder, available from http://www.I-AmPerfectlyHealthy.com
At the moment they have a special pre Christmas offer of Buy three jars and get one free, this really is a good deal.
Tell Maryanne, the owner, who is very helpful, that Alfred Jones from Australia, sent you, and you will be well looked after.
