Having gone through this myself, I can speak from experience.
Typically, taking probiotics is not the only step in fighting Candida. A vital step is to starve/weaken the Candida. This is mainly done by cutting out almost all sugar, grains, alcohol and legumes from your diet for a period of 3-6 months. You don’t have to follow the diet 100%, but the closer you follow it, the quicker the candida will die off. And they are some tough buggers!
I followed it 97% strictly for 10 days, and 99% of my SEVERE and gross dandruff disappeared…the dandruff was so bad that head and shoulders wouldn’t even stop it. My naturalpath doctor and I were floored to say the least.
After a few months on the diet, the probiotic supplements can begin to take back your body’s ecological habitat and establish effective colonies. But unless you weaken the candida, the probiotics will easily be defeated and won’t help set up permanent colonies…though the probiotics may help a bit with the symptoms of candida in the meantime.
The type of probiotics my Doctor recommended me were the “Re-juvi Flora Probiotic System”. Another good probiotic supplement comes from RenewLife – be sure to take 10-30 Billion daily (though you may need to build up to that amount – see here
If you want to read up further on Candida, check out the book “The Fungal Link” by Doug Kaufmann. It has more details on the diet, and shows how many diseases have been linked to fungal infections.
