Shiva,
Candex is an option, but it doesn’t work as good as Interfase. I really haven’t had to use Candex as an alternative. The Candex could be mixed in liquid, just like the Interfase. For people who are really, really sensitive to candida than starting with lower amounts, i.e. 1/4 capsule may be necessary.
The BioChelate is option I use for heavy metals. It is well tolerated and could help in the Biofilm process too. I have not used IMD, but have heard good things about the Quicksilver products.
Sincerely,
Dr. Woeller
