The tics are unlikely being triggered from candida. I would still treat the Candida, but would also do strep antibodies – ASO titer and Anti-DNAse B.
Also, the 5-HTP and/or Inositol may help the tics. I cannot say I have seen universal success though. In this case I would definite use 5-HTP first. This is a priority. The inositol could be used, but only after on 5-HTP for a few weeks.
Other probiotics – ProBiotic Support Formula from New Beginnings Nutritionals is good probiotic that doesn’t have the S. Thermophilus.
I hope this helps,
