My 6 year old son is allergic to dust, cats, and sensitive to some food additives. So far we have had reactions to 621-635 and 160b and are looking at 282 now. Just wanting to thank you for putting us on the right track to start with. Our son's nose was 90% full of swollen tissue. He was working 20% harder to breath giving him terrible headaches etc. He is now starting to feel better, sleeping better, behaving better (prev we were told it was adhd - have my doubts now) and generally feeling better - by email
