I have no idea why that brand contains rice flour, because obviously it doesn’t need to. There are a lot of brands here in the states without it. Since I don’t know how much it contains, I can’t tell you for certain that it won’t bother the treatment, but my guess would be that it’s not enough to make much of a difference.
Benc, you say you go through the Molybdenum so quickly; how much do you take a day and how long have you been taking it? Are you still experiencing bad die-off symptoms? Have you tested lowering your amount to see if the symptoms are worse?
