Yeast definitely has a smell. I have a fungal odor, some say it smells musty other say it smells like dirty hair. I use a sauna, take baths in essential oils and eat certified organic only. Mercury is the culprit. Even though I had all of my filings removed, the odor persists. It could also be from liver imbalance because it can cause odor as well.
Wishing you peace.
