They do have a prescript
ion version if Visbiome. It's the exact same formulation as VSL 3#DS was in January 2016. One of the lead creators left VSL and took his formulation but couldn't take the name VSL. Hence VSL adding corn starch to change their formulation.
If you visit their website you can read more info but yes they have the prescript
ion 900 billion sachets.
My insurance won't cover VSL or Visbiome at the prescript
ion level...stating that since I can buy it over the counter...after many appeal fights...I lost.
I am taking Visbiome sachets at 450 billion over the counter. I can't handle corn starch. I was originally taking 2 VSL #3DS sachets a day for 4 years (since diagnosis) until they stopped covering it.
I now take 1 or 2 (when needed) 450 billion sachets. Luckily my gut likes it (same formula as original VSL) and the lower dosage hasn't affected anything
