Gluten and/or Streptococcus in Probiotics in PANS / PANDAS (Lyme included) Posted October 19, 2012 · Report reply Holy Cow. Dr B recommended VSL 3 powder packets and I had to dig a little, but I discovered that they DO have strep in them. I do remember Dr T telling us to stay away from yogurt and other things with strep in them. Thanks SOOOO much for posting. Nickelmama-thanks for the alternative, I intend to order to ASAP.
