Jarrow FORMULAS® Beta Glucan is made from a special ß1,3 / ß1,6 glucan extract of the Baker’s yeast (Saccharomyces cerevisiae) cell walls. This product activates immune function by stimulation of NK cells, granulocytes, monocytes, and macrophages. After oral consumption, beta glucans are delivered to bone marrow granulocytes by macrophages travelling through lymphatic circulation.

This patented Beta Glucan preparation has demonstrated immunogenic activity in clinical trials.
