"As you probably know, we all naturally host Candida colonies, although in a healthy environment they do not dominate and create systemic imbalance; the body finds it more tolerable to have yeast overgrowth rather than the ultimately more damaging effects of uncontained mercury. It is not that the Candida contributes to health, but it is part of damage control.
The most important point here is that trying to fight Candida overgrowth without first bringing toxic levels of mercury to lower levels is a loosing battle. Once mercury is successfully reduced, Candida overgrowth can become manageable."
As far as the chlorella, make sure your Naturopath recommends one that has been tested for heavy metals. Because Chlorella binds so effectively with heavy metals, it often "picks them up" as it is being cultivated.
