Hi Charlotte and welcome to A2K.
First things first, let me say I am absolutely crazy about your son.

No news to you I am sure, that he is an absolute gem!! I have been wanting to meet you for the longest time and I know it will happen in due time. Personally, I can hardly wait, he has told me so many wonderful things about you.
I've been reading about the Conquer HA and there doesn't seem to be anything in it that can cause any harm, although the med label does list the caution that you should consult with your physician if you are taking any prescription medications, are pregnant or nursing (wouldn't that be a shocker!!) Also people with cancer, liver or kidney disease should not take this medication. Well...after reading of the warnings on the label and hearing testimonials that it is so safe, I dug a little further on the actual component of HA (Hyaluronic Acid) to find out why it , in itself would be risky for some individuals. I found an interesting article by a woman named Sandra Simmons who appears to have studied HA to great length.
Here is the link to her article if you have not read it already:

Again, I am very glad that you are here and I hope you stick around and get to know some of the different forums and posters within. There is definitely something for everyone here.
Looking forward to the future!
Jan
