Functional Yeast Extract (Saccharomyces cerevisiae) Cell Wall
Also known as: Baker's yeast extract, Saccharomyces cerevisiae cell wall, Yeast beta-glucan, Nutritional yeast extract
Functional yeast extract is derived from baker's yeast cell walls and is standardized to contain beta-glucans, polysaccharides that may support immune function. Research suggests beta-glucans can enhance innate immune responses, though human clinical evidence remains limited.

Evidence notes
Good mechanistic and in vitro evidence for beta-glucan immunomodulation. Some human studies show immune marker improvements (NK cell activity, cytokine production), but limited large-scale RCT data for clinical outcomes. Yeast extract extracts are less studied than purified beta-glucan isolates.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
