Why was this study done?
Previously we investigated the immuno-stimulatory effects on immune alert mediator production and immune cell proliferation of a blend of extracts containing polysaccharides including yeast beta-glucan in human immune cells isolated from blood of a healthy donor. We further explored other potential blends of natural extracts known to have immune enhancing properties.
What did the study find?
Ginseng and mushroom showed the beneficial immuno-stimulatory effects when used in combination with yeast beta-glucan.
