Something should also be said of which types of magnesium is best or most absorbable. Magnesium oxide is often used in multi supplements, but it is considered to be one of the least absorbable forms. If this is the main or only form in your supplements, than you can consider yourself as not having taken any. The absorbtion rate of Mg oxide is about 4%. The better forms to use are: 'Magnesium acetate, chloride, citrate, gluconate, glycinate, lactate, malate, succinate, sulfate, tartrate and taurate are all very good, ionizable sources of magnesium'(quoted from above article). Magnesium aspartate is also considered well absorbed. So, as you increase you magnesium intake be sure to use an absorbable form.
Also, in considering the 'which came first the chicken or the egg' aspect of candida, Mg deficiency, and dysbiosis, I have to make the observation that candida is known to be present in the healthy digestive tract of healthy people(whatever that may mean). And I personally believe that the candida has a beneficial role to play in the intestinal tract in healthy amounts. In fact, in the research I have done, I have read that the toxins released by the candida organism can and should actually be broken down in the normal Krebs cycle to produce a source of energy to the body. However, in the absence of adequate trace minerals, like molybdenum, the process is not completed and the acetaldehyde left adrift causes our systems innumerable problems. So to me, candida is not the cause, it is a symptom of something else.
Likewise, dysbiosis, is the result of something missing, which results in an overgrowth of something else, but it too is a symptome of what is missing. The presence of dysbiosis can and does exacerbate existing problems, and facilitate the formation of other problems, but it did not create the origin of the problem.
The origin to me, is whatever causes the original deficiency. This, in my opinion can be several specific things. It can be a healthy diet, that lacks one or two very important nutrients such as magnesium or ascorbic acid. Or it can be the inclusion of an ingredient that causes a specific reaction in the intestinal tract, such as gluten or milk for those incapable of processing it thru genetic predisposition. And of course, it can be the regular consumption of a diet deficient in nutrients and high in GI irritants. The symptoms may not be palpable until sufficient damage has been done. And this damage will have been creating deficiencies, and therefore, dysbiosis for some time before the individual becomes aware. This is the beginning of disease, and the playground of candida.
