  1. A daily dose of 2 x probiotic capsules. Each capsule contains 50 billion colony-forming units (CFU) of live organisms (Lactobacillus acidophilus +Lactobacillus casei +Lactobacillus rhamnosus JB-1.). the probiotic will be taken in addition to a prescribed dose of SSRI medication for participants with a demonstrated history of chronic treatment resistant depression.
  2. A daily dose of 1600mg of Orotic acid in the magnesium orotate form. Magnesium orotate will be taken in addition to a prescribed dose of SSRI medication for participants with a demonstrated history of chronic treatment resistant depression.
