Cracked Whole Cell

Cracked whole cell refers to the physical disruption of yeast cells, often *Saccharomyces cerevisiae*. This process breaks open the cell walls and membranes, releasing the cell's contents. The resulting material is then typically dried and powdered.

Manufacturers use cracked whole cell yeast as a source of protein, vitamins, and minerals, particularly B vitamins. It is often added to nutritional shakes, bars, and snacks to boost their nutritional profile.

In the US, yeast products like cracked whole cell are generally recognized as safe (GRAS) by the FDA when used as intended. Yeast is a source of nutrients, and its components are common in the diet. International bodies like JECFA and EFSA have evaluated yeast and its components. Evidence does not suggest adverse effects from typical dietary intake.
