hi Mommyb.. heres hoping you are feeling a little better lately.. I am justbrowsing, and noticed you didnt have any replies.. thats not fair, everyone should have some replies !
I think I would go to a health food shop, say, and ask advice, as whenever I have been in Holland and Barrett and asked anything, they always seem to want to help anyone, and can give advice and look up anything you need to know.. you can ask in confidence too.. so. good luck to you in this matter.
kind regards
w
