Is the bloom or yeast coating on fruit a source of B12?

yes....bloom or yeast coating on a fruit a source of vitamen B12

Another Answer

The bloom on fruit used to be thought of as wild yeast cells but we now know that it is a waxy covering found on the cells of the skin.

Vitamin B12 is usually found in meat, eggs and dairy products. Supplements and fortified foods are another source. Algae, miso and some other soy products have been reported to have B12 but it is not in a significant amount. Our bodies do make vitamin B12 in our intestines but the production location is far below the absorption location.
