Collodial silver worked for me for about a week and then did nothing after that. Hard to find products that actually work longer than a week. Candida fungus seems to adapt very quickly. Just finished a week of potassium sorbate. Worked great for about a week and then seems like the candida figured it out. Rotation might be a good idea considering how fast candida adapts to anti-fungals. Some candida experts recommend rotating anti-fungals.
