They look like such good products?
Yeah??? Well, ask the horses!
You might get more of a response over at the Yahoo Cushing's Board. I think some over there have used Phyto Quench and their horses were less than enthusiastic about it--of course, some horses might like it.

I'm a big fan of Bio-Quench and have used it for several years. My mildly-IR horse has bad reactions to insect bites and it seems to really help as a preventive during the summer months. Without it, he'll get all-over hives if the bugs really get him, and dust and pollen will give him goopy eyes, too. He does get some other supplements as well, but I definitely think the Bio-Quench helps him. It's expensive, though.
It's made by a company called Uckele - you can order it on their web site (look under antioxidants). They are notoriously expensive for shipping - I can't imagine what they'll charge to ship to the UK. Good luck!
