I order it from overseas...due to it's high cost. My insurance used to pay for it, but not anymore
I was just curious if there was a specific reason you questioned the other ingredients in this case. I'm not familiar with Titanium dioxide...but then again, I don't think I would know which ingredient is problematic when there is so many and the 'other ingredients' are typically in smaller amounts than the main ingredient.
If you have SIBO, then it is very effective for this. I have not had any side-effects from it and I'm actually taking it at the moment for the same reason.
In the US, it is $840 for 14 day at just 2 x daily (550mg)!!
