A great place to start is with any of these blogs: – website of Jeff Leach and – the two websites of Dr Grace Liu – website of Richard Nikoley – website of Tim Steele aka Tatertot – website of Shant Mesrobian – website of Matt Pepin


Blog Posts



  • Elixa Probiotic – a new UK manufactured high-strength, short-course probiotic.
  • Prescript Assist
  • Equilbrium
  • Primal Defense Ultra
  • Primal Flora
  • AOR Probiotic 3 – The enterobacteria contained in ProBiotic 3 act in symbiosis and promote a healthy intestinal flora. Lactic acid and butyric acid-producing probiotics inhibit the growth of pathogenic bacteria while promoting the growth of the beneficial Bifidobacterium strain.
  • Symbioflor – contains the natural intestinal bacteria Enterococcus faecalis and Escherichia coli, in inactive form. Grace Liu recommends this one.
