I take DIM from a company called NutriCost that I ordered on Amazon. But I recently read an article about how there is a patent on a special version of DIM and a company called Nature's Way has that patent. I just placed an order for Nature's Way DIM-Plus on Amazon and waiting to receive it. I will look for that article about DIM and post it but I will have to search for it and I need to shower and get to work. 

Lotus, thank you for the DIM info! I have been taking DIM for a while but didn't know that it was such a prize supplement!
