I have found that the standard recommended doses of gut bacteria are far too small to be effective in recolonisation of the right bacteria and have little effect on candida and fungal infections etc. A large crash course in bacterial recolonisation has been useful to initiate the right intestinal environment and then the standard doses of the right bacteria are useful as a maintenance. The right ingredients and the right type of ingredients in the vitamins and minerals are essential for intracellular uptake. Items in isolation are out of context and cannot be used. Most people are deficient in correct essential fatty acids and plentiful in toxic damaged fats.
Mercury interferes with fat metabolism and so does a high temperature.
Attending to correction of fatty acids could be most important and I have found it beneficial in the short term with circulatory problems. Thyroid support for amalgam toxicity is a necessary step to be considered in treatment. A subnormal temperature on waking is a good indication of a need in this area. Even a tiny subnormality could be significant. A knowledgeable practitioner will be able to advise here.
